question 1 options: two polygons are similar if and only if there is a correspondence among their angles and among their sides so that all corresponding angles are congruent and all corresponding sides are .

Answer:

B.   51 in²

Step-by-step explanation:

The area of a sector which has a central angle of θ degrees is given by
Area of circle x θ/360

where
area of circle = πr² with r being the radius

So area of sector = πr² x θ/360

here r = 14 in and θ=30°

Area of sector
= π x 14² x 30/360

= 51.31268 in²

≈ 51 in²

Answer:

The probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards is 11/26 or approximately 0.423.

Step-by-step explanation:

Part A

No, selecting a face card and selecting a spade when randomly selecting one card from a standard deck of cards are not mutually exclusive events. This is because there are face cards that are also spades, so there is an overlap between the two events.

Part B

The probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards can be calculated as follows

P(face card or spade) = P(face card) + P(spade) - P(face card and spade)

Part C

The probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards can be calculated as follows

P(face card or spade) = P(face card) + P(spade) - P(face card and spade)

P(face card or spade) = 12/52 + 13/52 - 3/52

P(face card or spade) = 22/52

P(face card or spade) = 11/26

Hence, the probability of selecting a face card or a spade when randomly selecting one card from a standard deck of cards is 11/26 or approximately 0.423.

As a result, it takes around 0.25 minutes for the oven to reach 300°F, or equation roughly 15 seconds. Rounded to the closest minute, the answer is 0 minutes.

A math equation is a mechanism for connecting statements and indicating equivalence with both the equals symbol (=). An equation is an algebraic claim that asserts the equivalency of two formulae in algebra. In the calculation 3x + 5 = 14, for example, the equivalence sign separates the numbers 3x + 5 and 14. To explain the relationship among the two words on each surface of a letter, a formula can really be employed. The software and the logo are usually interchangeable. For instance, 2x - 4 equals 2.

Set T = 300 in the equation and solve for t to discover the number of minutes it takes for the oven's temperature to reach 300°F:

T = 400 - It

300 = 400 - It / subtraction T = 300

It = 400 - 300

It = 100

t = 100 / I

T = 400 minus It I = (400 minus T) / t

When we substitute T = 0 and T = 1, we get:

I = (400 - 0) / 1\sI = 400

Now we can substitute I = 400 into the equation we found before for t:

t = 100 / I\st = 100 / 400\st = 0.25

As a result, it takes around 0.25 minutes for the oven to reach 300°F, or roughly 15 seconds. Rounded to the closest minute, the answer is 0 minutes.

(x + 2)2 + (y - 4)2 - 11 = 0

The equation of the circle in standard form is x2 + y2 + 36x - 72y + 11 = 0. To arrive at this answer, you need to complete the square for both the x and y terms in the equation. First, divide the equation by 9 to get the following:

x2 + y2 + 4x - 8y + 1 = 0

To complete the square for the x terms, add and subtract (4/2)2 = 16/4 = 4 to the equation:

x2 + 4 + y2 + 4x - 8y + 1 - 4 = -4

Simplifying gives you:

(x + 2)2 + y2 - 8y + 5 = 0

To complete the square for the y terms, add and subtract (8/2)2 = 64/4 = 16 to the equation:

(x + 2)2 + (y - 4)2 + 5 - 16 = -11

Simplifying gives you:

(x + 2)2 + (y - 4)2 - 11 = 0

This is the equation in standard form.

Answer:

[tex]y^2 = x^3 / 2^{3/2}[/tex] or [tex]y = x^{3/2} / 2^{3/4}[/tex]

Step-by-step explanation:

We can use the identity [tex]cos^3(t) = cos(t)*cos^2(t) and sin^3(t) = sin(t)*sin^2(t)[/tex] to rewrite the given parametric equations in terms of x and y:

[tex]x = 2cos(t)*cos^2(t) = 2x^2 - 2y^2[/tex]

[tex]y = 2sin(t)*sin^2(t) = 2xy^2[/tex]

Solving for y in terms of x, we get:

[tex]y = x^{3/2} / 2x^{3/4}[/tex]

Therefore, the cartesian equation of the curve is:

[tex]y = x^{3/2} / 2^{3/4}[/tex]

or, equivalently:

[tex]y^2 = x^3 / 2^{3/2}[/tex]

Answer:

c ≈ 11.2

Step-by-step explanation:

Using the distance formula, we have:

c = √[(x2 - x1)² + (y2 - y1)²]

c = √[(-7 - 3)² + (1 - (-4))²]

c = √[(-10)² + 5²]

c = √(100 + 25)

c = √125

c ≈ 11.2

Therefore, the distance between the two points is approximately 11.2 units.

[tex]\sqrt{(-7-3)^{2} + (1-(-4))^{2} } = \sqrt{(-10)^{2} + (5)^{2} } = \sqrt{100 + 25} \\[/tex]

1 kilogram of soil will fit in the container, since 1 kilogram is less than 27/5 kilograms.

We can start by using ratios to solve this problem.

From the information given, we know that:

We want to know how much soil will fit in the entire container (which is equivalent to 3 times the amount that fills 1/3 of the container)

To find out how much soil fills the entire container, we can set up a ratio:

(3/5 kg of soil) : (1/3 of container) = (x kg of soil) : (1 container)

We can cross-multiply to solve for x:

(3/5 kg of soil) * (1 container) = (1/3 of container) * (x kg of soil)

Multiplying both sides by 3/1 gives:

(3/5) * 3 * (1 container) = (1/3) * x

Simplifying gives:

9/5 = 1/3 * x

Multiplying both sides by 3 gives:

By answering the given question, we may state that Therefore, the equivalent inequality is: x < 2

A relationship between two terms or values which is not equal is known as an inequality in mathematics. Inequality follows imbalances, therefore. In mathematics, an inequality makes a link among two quantities that are not equal. Egality and inequality are different. Use the not similar symbol most frequently when two components are not equal (). Various inequalities are employed to contrast values of all sizes. By changing the two parts until only the variables are left, one can solve many straightforward inequalities. However a variety of factors support inequality: Negative values are split or added on either side. Switch between the left & right.

How to calculate mean and median?

Given data set:

58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57

Median = (100 + 105) / 2

Mean = (58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57) / 12

= 965 /12

= 80.4°

Range = Highest value - lowest value

= 105 - 57

= 48°

Interquartile range = Third quartile - First quatile

= 88.5° - 74°

Answer:

Add to eliminate X

Step-by-step explanation:

To eliminate a variable, we need to make its coefficient equal and opposite in the two equations. In this case, we can see that the coefficient of x in both equations is the same (6x), so we can eliminate x by adding the two equations.

When we add the two equations, the x term will cancel out, leaving us with the equation:

9y = 36

We can then solve for y by dividing both sides by 9:

y = 4

Now that we know the value of y, we can substitute it back into one of the original equations to solve for x. Let's use the first equation:

6x + 5y = 12

6x + 5(4) = 12

6x + 20 = 12

6x = -8

x = -4/3

Therefore, the solution to the system of equations is x = -4/3, y = 4.

Polynomial multiplication is the process of multiplying two polynomials together to get a new polynomial that represents the product of the two original polynomials.

It should be noted that to multiply two polynomials, you need to perform a distributive operation. You take each term of the first polynomial and multiply it by each term of the second polynomial. Then, you add all the resulting terms together to get the final polynomial.

For example, let's say you want to multiply the polynomials (x + 2) and (x - 3).

First, you multiply the x term in the first polynomial by the x term in the second polynomial:

(x) * (x) = x²

Next, you multiply the x term in the first polynomial by the -3 term in the second polynomial:

(x) * (-3) = -3x

Then, you multiply the 2 term in the first polynomial by the x term in the second polynomial:

(2) * (x) = 2x

Finally, you multiply the 2 term in the first polynomial by the -3 term in the second polynomial:

(2) * (-3) = -6

Now, you add up all the resulting terms to get the final polynomial:

x² - x - 6

Therefore, the product of (x + 2) and (x - 3) is x² - x - 6.

Answer:

To find the perimeter and area of the square garden shed without graphing the coordinates, you can use the distance formula to calculate the length of one side of the square. The distance formula is d = √((x2 - x1)^2 + (y2 - y1)^2), where (x1, y1) and (x2, y2) are the coordinates of two points. Using this formula with the coordinates of two adjacent corners of the square, such as (-2,8) and (1,8), we find that the length of one side of the square is 3 units. Since all sides of a square are equal in length, the perimeter is 4 times the length of one side, or 12 units. The area of a square is equal to the length of one side squared, so the area of the square garden shed is 9 square units.

This problem is different from finding the perimeter and area of the base of a house because it involves a square shape rather than a more complex shape. However, you can use similar strategies to solve both problems by calculating distances between points and using geometric formulas to find perimeter and area. The specific formulas used may vary depending on the shape of the base of the house.
