Answer:
We can use the formula for the area of a triangle to solve for the height of the isosceles triangle, which will then allow us to find the lengths of the other two sides.
Let h be the height of the isosceles triangle, and let s be the length of each of the two equal sides. Then the area of the triangle is given by:
A = (1/2)bh = (1/2)(10m)(h) = 5h
We also know that the area of the triangle is 60 square meters, so we can set these two expressions equal to each other and solve for h:
5h = 60
h = 12
Now that we know the height of the triangle is 12 meters, we can use the Pythagorean theorem to find the length of each of the other two sides:
s^2 = h^2 + (1/2b)^2
s^2 = 12^2 + (5^2)
s^2 = 169
s = sqrt(169)
s = 13
Therefore, the lengths of the other two sides of the isosceles triangle are both 13 meters.
Yuri's dad needs to fertilize the grass in the yard. The back yard measures 55 feet by 30 feet, while the front yard is a square with a length of 42 feet on each side
Answer: To find the total area of the grass that Yuri's dad needs to fertilize, we need to calculate the area of the back yard and the area of the front yard, and then add them together.
Area of the back yard:
The back yard measures 55 feet by 30 feet, so the area is:
55 feet x 30 feet = 1650 square feet
Area of the front yard:
The front yard is a square with a length of 42 feet on each side, so the area is:
42 feet x 42 feet = 1764 square feet
Total area:
To find the total area, we add the area of the back yard and the area of the front yard:
1650 square feet + 1764 square feet = 3414 square feet
Therefore, Yuri's dad needs to fertilize a total area of 3414 square feet.

Part2) Write a polynomial for the area of the rectangle
The perimeter of the rectangle is (x² + 30x + 104) in² while The area of the rectangle is (x² + 30x + 104) in²
What is an equation?An equation is an expression that shows how two or more numbers and variables are related using mathematical operations of addition, subtraction, multiplication, division, exponents and so on.
The rectangle have a length of (0.5x + 13) and width of (2x + 8)
1) Perimeter = 2(length + width)
Perimeter = 2(0.5x + 13 + 2x + 8) = 2(2.5x + 21) = (5x + 42) inches
The perimeter of the rectangle is (x² + 30x + 104) in²
2) Area = length * width
Area = (0.5x + 13) * (2x + 8) = x² + 4x + 26x + 104
Area = (x² + 30x + 104) in²
The area of the rectangle is (x² + 30x + 104) in²

Answer:
We know that 120 can be factored as 2^3 * 3 * 5, so its totient function value can be found as follows:
φ(120) = φ(2^3) * φ(3) * φ(5)
= 2^2 * 2 * 4
= 16
Therefore, there are 16 numbers less than or equal to 120 that are relatively prime to 120
Question 1 (3 points) Saved If A and B are independent events
with P(A) = 0.4 and P(B) = 0.25, then P(A ∪ B) = Question 1
options: 0.65 0.55 0.10 Not enough information is given to answer
this quest
The value of the probability P(A ∪ B) if the events are independent events is 0.55
How to determine the value of the probabilityThe formula for the probability of the union of two events is:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
Since the events A and B are independent, the probability of their intersection is simply the product of their individual probabilities:
P(A ∩ B) = P(A) × P(B)
Substituting the given values, we have:
P(A ∩ B) = 0.4 × 0.25 = 0.1
Now we can use the formula for the union:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
So, we have
P(A ∪ B) = 0.4 + 0.25 - 0.1
This gives
P(A ∪ B) = 0.55
Therefore, the probability of the union of events A and B is 0.55.

(1 point) A tank contains 60 kg of salt and 2000 L of water. Pure water enters a tank at the rate 8 L/min. The solution is mixed and drains from the tank at the rate 4 L/min. (a) What is the amount of salt in the tank initially
The initial amount of salt in the tank is 60 kg, calculated using the formula M = ρV, where M is the mass of the salt, ρ is the density of the salt, and V is the volume of the tank.
Initially, the tank contains 60 kg of salt and 2000 liters of water. The amount of salt in the tank can be calculated using the formula M=ρV, where M is the mass of the salt, ρ is the density of the salt, and V is the volume of the tank. The density of salt is 2270 kg/m3. Assuming the tank has a constant volume, the mass of the salt in the tank is 60 kg.
The amount of salt in the tank changes due to the addition of pure water and mixing of the solution. The amount of salt in the tank at any given time can be calculated using the formula M=ρV, where M is the mass of the salt, ρ is the density of the salt, and V is the volume of the tank. The rate at which the salt is added to the tank is equal to the rate at which the salt-water solution is drained from the tank.
Therefore, the rate of change of the mass of the salt in the tank is equal to 8 liters/minute of pure water entering the tank minus 4 liters/minute of salt-water solution draining from the tank. Thus, the amount of salt in the tank initially is 60 kg.

The probability of getting at least one "r" of the alphabet if letters of the alphabet are selected at random is 1/1.
The reason for this is that if any letter of the alphabet is selected at random, the probability of getting an "r" is 1/26, or 0.0385. Since letters can be used more than once, this probability remains the same regardless of how many letters are selected. Thus, the probability of getting at least one "r" of the alphabet if letters of the alphabet are selected at random is 1.
In summary, the probability of getting at least one "r" of the alphabet if letters of the alphabet are selected at random is 1. This is because, when a letter is selected at random, each letter has an equal chance of being chosen (1/26), and since the probability of selecting an "r" remains the same regardless of how many letters are selected, the probability of getting at least one "r" is also 1.

During a basketball game, Jeremy scored triple the number of points as Donovan. Kolby scored double the number of points as Donovan.
If the three boys scored 36 points, how many points did each boy score?
Donovan scored 6 points, Jeremy scored 18 points, and Kolby scored 12 points.
Let's denote the number of points scored by Donovan as "D".
According to the problem, Jeremy scored triple the number of points as Donovan, so he scored 3D points.
Similarly, Kolby scored double the number of points as Donovan, so he scored 2D points.
We also know that the total number of points scored by all three boys is 36. So we can write an equation:
D + 3D + 2D = 36
Simplifying this equation, we get:
6D = 36
Dividing both sides by 6, we get:
D = 6
So Donovan scored 6 points.
Using the values we found for Donovan's score, we can find the scores of Jeremy and Kolby:
Jeremy scored 3D = 3(6) = 18 points
Kolby scored 2D = 2(6) = 12 points
Therefore, Donovan scored 6 points, Jeremy scored 18 points, and Kolby scored 12 points.

Jimmy volunteers at events at the hospital each year.
The random variable x is the number of hospital events Jimmy works at each year.
What values dose x take on?We understand that he does not work for more than two events in a year
So, x can take on the values 0, 1, or 2.

He attended exactly two events seven timesOne event two timesNo events one timeSo, the table is
X P(X)
0 0.1
1 0.2
2 0.7
To find the expected value, we take the sum of the products of x and P(x)
So, we have
E(x) = 0(0.1) + 1(0.2) + 2(0.7)
E(x) = 1.6
To find the standard deviation, we need to first calculate the variance:
Var(X) = E(x^2) - [E(x)]^2
Where
E(x^2) = 0^2(0.1) + 1^2(0.2) + 2^2(0.7)
E(x^2) = 3
So, we have
Var(X) = 3 - (1.6)^2
Var(X) = 0.44
This means that
SD(x) = √0.44
SD(x) = 0.66
Hence, the standard deviation is 0.66

Which fractions have 20 as the LCD (lowest common denominator)?
The lowest common denominator, 20, can be used to represent any fraction that can be stated as a ratio of integers with factors of 2 and 5 in the denominator. eg. 1/4, 1/2, 2/5 and 7/10
To find all the fractions that have 20 as the lowest common denominator, we need to identify all the prime factors of 20, which are 2, 2, and 5.
Then, we can express each fraction with these prime factors in the denominator, by multiplying the numerator and denominator by the missing factors. For example, for the fraction 1/4, we need to multiply both the numerator and denominator by 5 to get:
1/4 = 5/20
Similarly, for the fraction 3/5, we need to multiply both the numerator and denominator by 2 to get:
3/5 = 6/10 = 12/20
By doing this for all fractions, we can express them with the same denominator of 20. Here are some examples:
1/4 = 5/20
3/5 = 12/20
1/2 = 10/20
2/5 = 8/20
7/10 = 14/20
Therefore, any fraction that can be expressed as a ratio of integers with factors of 2 and 5 in the denominator can be written with 20 as the lowest common denominator.

The domain and range of g of x equals the square root of the quantity x plus 4, g(x) = √x + 4, are equal to d: [–4, [infinity]) and r: [0, [infinity]). Thus, the right choice of answer is option (c).
We have a function g(x) and defined as square root of the quantity x plus 4, i.e.,
g(x) = √x + 4
We have to determine the domain and range of function g(x).
The domain of function is all input values of x that make the expression defined. The range is the set of all output values that valid g(x) values. A square root limits the function because we can't have negative numbers under the square root (they become imaginary numbers). Let y = g(x) = √x +4
the square root '√ 'sign must be implies ≥ 0, therefore, x + 4 ≥ 0
Subtracting the 4 from both sides
=> x + 4 -4 ≥ 0 - 4
=> x ≥ -4
The domain is x∈ [-4,+∞)
When x = -4, g(x) = 0
Therefore, The range is y∈ [0, 00)

find the length of side 3
answers
5x^3-4x^2+3x-4
5x^3-4x+3x-12
5x^3-4x^2+3x+4
5x^3=4x^2+3x+12
Answer:
Side 3 is: 5x^3 - 4x^2 +3x - 12
Note that the answer options do not include this result, but it is likely that the second option is simply missing the square term for the -4x, and it should read -4x^2.
Step-by-step explanation:
The perimeter is the sum of all three sides. To find Side 3, subtract Sides 1 and 2 from the perimeter:
5x^3 - 2x^2 +3x - 8 - (3x^2-4x-1) - (4x-x^2+5) = Side 3
Perimeter - Side 1 - Side 2 = Side 3
5x^3 - 2x^2 +3x - 8 - 3x^2+4x+1 - 4x+x^2-5 [Remove parentheses]
5x^3 - 3x^2 +x^2 - 2x^2 +3x +4x - 4x - 8 +1 -5 [Combine like terms]
5x^3 - 4x^2 +3x - 12 [Simplify] = Side 3
A, B and C lie on a straight line. Given that angle y = 95° and angle z = 330°, work out x .
If A, B, and C lie on a straight line, the sum of angles y, x, and z will be 180 degrees:
y + x + z = 180
Substituting the values given in the problem:
95 + x + 330 = 180
Simplifying:
425 + x = 180
Subtracting 425 from both sides:
x = -245
Therefore, x is -245 degrees.
However, since x represents an angle on a straight line, we can add 180 degrees to get an equivalent angle:
x + 180 = -245 + 180 = -65
Therefore, x is -65 degrees.

Ahmet borrows $700 and is charged compound interest at 15% per year. How much will he have to pay back in total after 6 years?
Give your answer to two decimal places.
Answer:
The required amount Ahmet needs to pay after 6 years is $1619.14.
What is compound interest?
Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
Amount = principal[1 + r/n]ⁿᵃ
Principal = P rate= r Time =a , n = compounding frequency
Here,
From the given data,
P = 700, r = 15% and t = 6 (n =1)
Now,
Amount = principal[1 + r/n]ⁿᵃ
Amount = 700(1 + 0.15)⁶
Amount = $1619.14
Thus, the required amount Ahmet needs to pay after 6 years is $1619.14.
Step-by-step explanation:
ABCD is a parallelogram and CE stands on AD, DF stands on AB. If AD = 20 metre, CE = 8 metre, AB = 16 metre, find DF
In the parallelogram ABCD the value of DF is 13.33 metres or DF = 40/3 metres (rounded to two decimal places).
In the parallelogram ABCD, we can draw a diagonal AC that splits the parallelogram into two congruent triangles, namely, △ABC and △ADC.
Let x be the length of DF. We can use similar triangles to find x.
Notice that △BCE and △DFE are similar triangles, since they share the same angle at E and the angles at B and D are congruent due to opposite angles in a parallelogram. Therefore, we can write the following proportion:
BC/CE = DF/FE
Substituting the given values, we have:
16/8 = x/(20-x)
Simplifying this equation, we get:
2 = x/(20-x)
2(20-x) = x
40 - 2x = x
3x = 40
x = 40/3
Therefore, DF = 40/3 meters or 13.33 meters (rounded to two decimal places).
