Answers

Answer 1

The answer is 140 tamales would remain.

What is an expression?

An expression is a combination of numbers, variables, and mathematical operations, such as addition, subtraction, multiplication, and division, among others. It is a mathematical phrase that represents a value or a set of values when evaluated.

We are given that Claudio made 300 tamales to give to pedestrians. Let the number of tamales Claudio passed out to pedestrians be represented by p.

If we assume that Claudio passed out p tamales, then the number of tamales remaining would be:

300 - p

If Claudio passed out samples to 160 pedestrians, then the number of tamales remaining would be:

300 - 160 = 140

Therefore, 140 tamales would remain.

One angle of a triangle measures 10°. The other two angles are in a ratio of 3:14. What are the measures of those two angle

Answers

Answer: Let's denote the two unknown angles as x and y.

We know that the sum of the three angles in a triangle is 180 degrees. So we can set up the following equation:

10 + 3x + 14x = 180

Simplifying the equation:

17x = 170

x = 10

Now we can use the ratio of the other two angles to find the value of y:

3:14 can be simplified as 3x:14x or x:4.67x

So y is 4.67 times larger than x:

y = 4.67x = 4.67(10) = 46.7

Therefore, the measures of the two unknown angles are x = 10 degrees and y = 46.7 degrees.

Step-by-step explanation:

The measure of the remaining two angles are 46.7

What is the angle sum property of a triangle?

Show that abcd is a trapezoid

Answers

Slope AB = slope CD = 1/1 and slope BC ≠ slope DA. Therefore, AB and CD are parallel sides, and ABCD is a trapezoid.

Describe Trapezoid?

In geometry, a trapezoid (also known as a trapezium in some countries) is a quadrilateral with at least one pair of parallel sides. The parallel sides are called the bases of the trapezoid, and the other two sides are called the legs.

The trapezoid can be classified into three types based on the positions of the bases:

Isosceles trapezoid: A trapezoid in which the non-parallel sides are congruent.

Right trapezoid: A trapezoid in which one of the angles formed by the legs is a right angle.

Scalene trapezoid: A trapezoid in which none of the sides are congruent.

The area of a trapezoid can be calculated by the formula:

A = (b1 + b2)h/2

where b1 and b2 are the lengths of the bases and h is the height of the trapezoid (the perpendicular distance between the bases).

To show that ABCD is a trapezoid, we need to demonstrate that it has at least one pair of parallel sides. One way to do this is to calculate the slopes of the line segments that connect the vertices.

The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:

slope = (y2 - y1) / (x2 - x1)

Using this formula, we can calculate the slopes of the four line segments:

slope AB = (4 - 1) / (2 - (-1)) = 3/3 = 1

slope BC = (1 - 4) / (3 - 2) = -3/1 = -3

slope CD = (-3 - 1) / (-3 - 3) = -4/-6 = 2/3

slope DA = (1 - (-3)) / (-1 - (-3)) = 4/2 = 2

We can see that slope AB = slope CD = 1/1 and slope BC ≠ slope DA. Therefore, AB and CD are parallel sides, and ABCD is a trapezoid.

The x-intercept of function g is

Answers

The x-intercept of g(x) is (3,0) and the vertex of g(x) is (3,0).

What is the x-intercept of the function?

To find the x-intercept of the quadratic function g(x), we need to set g(x) equal to zero and solve for x:

0 = -5(x - 3)²

Dividing both sides by -5, we get:

0 = (x - 3)²

Taking the square root of both sides, we get:

x - 3 = 0

x = 3

So the x-intercept of the function g(x) is (3,0).

To find the vertex of the function g(x), we can use the formula:

vertex = (h, k)

where;

h is the x-coordinate of the vertex and k is the y-coordinate of the vertex.

For a quadratic function in the form:

f(x) = a(x - h)² + k

the vertex is located at the point (h, k).

In the given function g(x), we can see that a = -5, h = 3, and k = 0.

So the vertex of the function g(x) is:

vertex = (h, k) = (3, 0)

Answers

Answer:

[tex]1/4\\[/tex]

Explanation:

To subtract 2/3 from 11/12, we need to find a common denominator for the two fractions. The least common multiple (LCM) of 3 and 12 is 12. We can rewrite each fraction with a denominator of 12:

11/12 - 2/3 = (11/12) - (2/3) * (4/4) (Multiplying the denominator and numerator of 2/3 by 4 to get a denominator of 12)

11/12 - 8/12 = 3/12

Now that both fractions have a common denominator of 12, we can subtract the numerators:

11/12 - 2/3 = (11 - 8)/12 = 3/12

Simplifying this fraction by dividing both the numerator and denominator by 3, we get:

3/12 = 1/4

Therefore, 11/12 - 2/3 = 1/4.

Omar has 7 2/5​ yards of ribbon to make bows. Each bow is made from a piece of ribbon that is 3/5 yard long. What is the maximum number of complete bows Omar can make?

Answers

Omar can make a maximum of 12 complete bows from the given length of ribbon.

How To find the maximum number of complete bows?

To find the maximum number of complete bows Omar can make, we need to divide the total length of ribbon he has by the length of ribbon needed for each bow, and then round down to the nearest whole number since we can only make complete bows.

First, we need to convert 7 2/5 yards to an improper fraction so that we can work with it more easily. To do this, we multiply the whole number (7) by the denominator of the fraction (5), and then add the numerator (2):

7 2/5 = (7 x 5) + 2/5 = 35/5 + 2/5 = 37/5 yards

Now we can divide the total length of the ribbon by the length needed for each bow:

37/5 ÷ 3/5 = 37/5 x 5/3 = 37/3

This gives us a fraction, but we want a whole number, so we round down to the nearest integer:

37/3 ≈ 12.33

Since we can only make complete bows, the maximum number of bows Omar can make is 12.

Therefore, Omar can make a maximum of 12 complete bows from the given length of ribbon.

In a math class with 23 students, a test was given the same day that an assignment was due. There were 15 students who passed the test and 18 students who completed the assignment. There were 13 students who passed the test and also completed the assignment. What is the probability that a student chosen randomly from the class failed the test and did not complete the homework?

Answers

Answer: To find the probability that a student chosen randomly failed the test and did not complete the homework, we need to subtract the number of students who passed the test and/or completed the homework from the total number of students in the class. Then, we can divide that number by the total number of students in the class to get the probability.

To start, we can use the information given in the problem to create a Venn diagram:

```

Test

|------|------|

| | |

Fail | | |

| | |

--------|------|------|

| | |

| | |

Pass | | |

Assignment|------|------|

| | |

| | |

```

From the diagram, we can see that the number of students who failed the test and did not complete the homework is the number of students outside the intersection of the two circles. To find this number, we can add the number of students who passed the test but did not complete the homework to the number of students who completed the homework but did not pass the test, and then subtract the number of students who passed the test and completed the homework:

Number of students who failed the test and did not complete the homework = (Number of students who passed the test but did not complete the homework) + (Number of students who completed the homework but did not pass the test) - (Number of students who passed the test and completed the homework)

Number of students who failed the test and did not complete the homework = (15 - 13) + (18 - 13) - 13

Number of students who failed the test and did not complete the homework = 4

Therefore, there are 4 students who failed the test and did not complete the homework.

To find the probability of choosing one of these students at random, we can divide the number of students who meet both conditions by the total number of students:

Probability of choosing a student who failed the test and did not complete the homework = Number of students who failed the test and did not complete the homework / Total number of students

Probability of choosing a student who failed the test and did not complete the homework = 4 / 23

Probability of choosing a student who failed the test and did not complete the homework ≈ 0.17

Therefore, the probability that a student chosen randomly from the class failed the test and did not complete the homework is approximately 0.17, or 17% (rounded to two decimal places).

suppose that a factory produces light bulbs and the percentage of defective lightbulbs is 3.5%. if a sample of 550 light bulbs is selected at random, what is the probability that the number of defective bulbs in the sample is greater than 15?

Answers

The probability that the number of defective bulbs in the sample is greater than 15 is  0.401, or 40.1%.

This is a binomial distribution problem with n=550 and p=0.035. We want to find the probability that the number of defective bulbs in the sample is greater than 15, which can be written as P(X > 15), where X is the number of defective bulbs in the sample.

Using the binomial probability formula, we have:

P(X > 15) = 1 - P(X ≤ 15)

P(X ≤ 15) = Σi=0¹⁵ (550 chooseᵃ) * 0.035ᵃ * (1-0.035)⁵⁵⁰⁻ᵃ

We can use software or a calculator with a binomial probability distribution function to find this sum, which is approximately 0.599.

Therefore, the probability that the number of defective bulbs in the sample is greater than 15 is:

P(X > 15) = 1 - P(X ≤ 15) ≈ 1 - 0.599 = 0.401

So the probability that more than 15 bulbs in the sample are defective is approximately 0.401, or 40.1%.

The quadratic equation written in vertex form is:

A(x) = x^2 - 4

How to write the equation in vertex form?

Here we want to find the vertex form of the quadratic equation:

A(x) = (x + 2)*(x - 2)

Remember that for a quadratic equation with the vertex (h, k) and leading coefficient a is written as:

f(x) = a*(x - h)^2 + k

Now, notice that the zeros of the quadratic function are x = -2 and x = 2.

Then the vertex is just between these two, at x = 0.

Then h = 0, and the y-value of the vertex is what we get when we evaluate in x = 0.

k = (0 + 2)*(0 - 2) = 2*-2 = -4

Then the vertex is (0, -4) and the leading coefficient is 1, we can write the quadratic equation as:

A(x) = (x - 0)^2 -4

Answers

Therefore , the solution of the given problem of area comes out to be the cone has a 5 millimetre height.

What exactly is area?

Calculating how much space would be needed to fully cover the outside will reveal its overall size. When calculating a trapezoidal form's surface, the environs were also taken into account. The surface area of something determines its overall measurements. The amount of edges connecting each of a cuboid's four parallelogram ends reveals how much underground water it can hold.

Here,

Let's name the cone using the details provided:

Its base measures 25 mm2.

A parallel slice 6 mm from the vertex has a 36 mm2 surface.

We can use the fact that the area of a circular slice of a cone is proportional to the square of its distance from the vertex to build up a proportion:

(area of slice) / (base area) Equals (distance from vertex) / (height) 2/ (area from slice)

When we enter the numbers we are aware of, we obtain:

=> 36 / 25 = 6² / h²

If we simplify, we get:

=>  h² = (25 * 6²) / 36 = 25

When we square the two edges, we obtain:

=>  h = 5

As a result, the cone has a 5 millimetre height.

What in geometry is a transformation matrix?

For describing a geometric transformation such a translation, rotation, scaling, or shearing, a matrix known as a transformation matrix is utilised. By multiplying the matrix by the column matrix of the original coordinates, the matrix is used to change the coordinates of points in a geometric figure. The modified figure is then drawn using the resultant transformed coordinates.

Given that the coordinates of the point are:

S(3, 6), T(4,4), and U(5,1)

When the figure is rotated by 90 degrees the resultant image has the following coordinates.

(x, y) → (-y, x)

Thus,

S(3, 6) →  (-6, 3)

T(4,4) → (-4, 4), and

U(5,1) → (-1, 5)

The rank of a matrix can be determined by converting it to its reduced row echelon form. It is also known as the row reduced echelon form or simply the reduced echelon form. The rank of a matrix is the number of non-zero rows in its reduced row echelon form. The given matrix is,

`A=[[2,3,-1,-1],[1,-1,-2,-4],[3,1,3,-2],[6,3,0,-7]]`

We need to convert the given matrix to its reduced row echelon form. It is done by applying elementary row operations on the matrix. The elementary row operations are as follows:

- Interchange the order of two rows.
- Multiply a row by a non-zero scalar.
- Add a multiple of one row to another row.

Let us apply these operations on the given matrix,

`[[2,3,-1,-1],[1,-1,-2,-4],[3,1,3,-2],[6,3,0,-7]]`

`= [R1, R2, R3, R4]`

`R1 → R1 - R2/2` (subtract half of R2 from R1)
`R2 → R2 - R1/2` (subtract half of R1 from R2)
`R3 → R3 - 3R1/2` (subtract three times half of R1 from R3)

`[[1,5/2,1/2,1/2],[0,-3/2,-5/2,-9/2],[0,-7/2,3/2,-7/2],[0,0,-3,-6]]`

`= [R1, R2, R3, R4]`

`R2 → -R2/3` (multiply R2 by -1/3 to make its first entry as 1)
`R3 → R3 - 7R2/3` (subtract 7 times -1/3 of R2 from R3)
`R4 → -R4/3` (multiply R4 by -1/3 to make its first entry as 1)

`[[1,5/2,1/2,1/2],[0,1,5/3,3/2],[0,0,-4/3,-4],[0,0,1,2]]`

`= [R1, R2, R3, R4]`

`R3 → -3R3/4` (multiply R3 by -3/4 to make its third entry as 1)

`[[1,5/2,1/2,1/2],[0,1,5/3,3/2],[0,0,1,1],[0,0,1,2]]`

`= [R1, R2, R3, R4]`

`R4 → R4 - R3` (subtract R3 from R4 to make its third entry as 0)

`[[1,5/2,1/2,1/2],[0,1,5/3,3/2],[0,0,1,1],[0,0,0,1]]`

`= [R1, R2, R3, R4]`

The given matrix is converted to its reduced row echelon form. The last row contains only a single non-zero entry, hence the rank of the matrix is 4.

Find the amplitude, phase shift, and period of the function.
y = 2 – (1/2) cos (3x+π)
Give the exact values, not decimal approximations. Amplitude: ___
Phase shift: ___
Period: ____

Answers

The amplitude οf the functiοn is 1/2, the phase shift is (-π)/3, and the periοd is 2π/3.

What is Phase Shift?

Phase shift simply means that the twο signals are at different pοints οf their cycle at a given time.

The given functiοn is y = 2 – (1/2) cοs (3x+π).

We can see that the general fοrm οf this functiοn is y = A cοs (Bx - C) + D, where A is the amplitude, B is the frequency, C is the phase shift, and D is the verticaI shift.

Cοmparing the given functiοn with the general fοrm, we can see that:

A = 1/2

B = 3

C = -π

D = 2

Therefοre, the amplitude is |A| = 1/2.

The phase shift is given by C/B = (-π)/3.

The periοd οf the functiοn is given by T = 2π/B = 2π/3.

The equivalent expression is 9b^6/a^4c^6

What is an equivalent expression?

An equivalent expression is a mathematical expression that has the same value as another expression, even though it may be written differently. Equivalent expressions can be useful in simplifying complex mathematical expressions or in solving equations by replacing a complex expression with a simpler, equivalent one.

In algebra, two expressions are considered equivalent if they simplify to the same expression, or if they have the same solution set when solved.

We have that;

(-3ab^2c^-3/a^3b^-1)^2

9a^2b^4c^-6/a^6b^-2

9a^-4b^6c^-6

9b^6/a^4c^6

A cylinder has a height of 23 m and a volume of 18,488 m³. what is the radius of the cylinder? round your answer to the nearest whole number. responses 256 m 256 m 50 m 50 m 32 m 32 m 16 m

Answers

Answer:

Step-by-step explanation:

The volume for a right cylinder is

[tex]V=\pi r^2h[/tex]

We are given all the values except the radius, so we plug them in as follows:

[tex]18488=\pi r^2(23)[/tex]

Begin by dividing by 23π to get

255.8657603 = r²

and then take the square root of both sides to find that

r = 15.995 or 16 m

Do you know the answer?

Answers

Answer:

A. No Solution

B. Unique Solution (0,0)

Step-by-step explanation: When you are dealing with a system of equations and they have the same variables with the same coeffiencts adding up to different numbers, it is unsolvable and therefore has no-solution. When you are dealing with two y-values equaling different amounts of x-values, 0 satisfy both varaibles.

If you approach this from a graphing perspective, you can put both equations in the system into slope intercept form.

System A:

Line 1: 3x + 5y = 8

                  5y = -3x + 8

                    y = -3/5 x + 8/5

Line 2: 3x + 5y = 7

                  5y = -3x + 7

                    y = -3/5 x + 7/5


Because both lines have the same slope, but different y-intercepts, the lines are parallel and will never intersect.  This is why there is no solution to the system.

System B:

Line 1: y = 7x is in slope intercept form.

Line 1: y = 3x is in slope intercept form.

Since these lines have different slopes, they are guaranteed to intersect only once.  There is a single solution.

If you graph these lines, they will intersect at the origin, at (0,0), since that is a common point on both lines.

C=9 when p=7 write an equation for c in terms of p

Answers

The equation for c in terms of p is c = (9/7)p. To obtain this equation, we use the given values of C and p to find the constant of proportionality.

We know that c and p are directly proportional, which means that c = kp for some constant k. We can find k by plugging in the given values:

9 = k(7).

We can solve this system of equations for k by using elimination or substitution. Solving for k, we get

k = 9/7.

Thus, the equation for c in terms of p is

c = (9/7)p.
