An animal pen is in the shape of a triangle. One of the interior angles of the triangle is 40 degrees. The measure of the other interior angles are in the ratio 3 : 5. What are the measures of the other interior angles?
Final answer:
In a triangle, the sum of all interior angles is always 180 degrees. Given the ratio of the other interior angles, we can find their measures.
Explanation:
In a triangle, the sum of all interior angles is always 180 degrees. Given that one of the interior angles is 40 degrees, let's denote the measures of the other two angles as 3x and 5x. The sum of all three angles is 40 + 3x + 5x = 180. Simplifying this equation, we get 8x + 40 = 180. Subtracting 40 from both sides gives us 8x = 140. Dividing both sides by 8, we find x = 17.5.
Now, we can substitute the value of x back into the expressions for the other two angles. So, the first angle is 3x = 3(17.5) = 52.5 degrees, and the second angle is 5x = 5(17.5) = 87.5 degrees.

Mary bought 3 cartons of milk for $1.06 each. If she paid for the milk with a five-dollar bill, how much money should she get back
Answer:
shed get $1.82 back
Step-by-step explanation:
Answer:
She would get $1.82 back
Step-by-step explanation:
If she bought 3 cartons costing $1.06 each, you would have to multiply $1.06 by 3
$1.06 x 3 = $3.18
Then if she paid with a five dollar bill you have to subtract $3.18 from 5
5 - 3.18 = 1.82
$1.82 is the answer
The daily high temperatures in Philadelphia for the first 15 days in February is normally distributed with a standard deviation of 2.5°. If it was 37° on Valentine's Day with a z-score of 2.4, the mean temperature is _________°.Immersive Reader
Answer:
The mean temperature is 31.
Step-by-step explanation:
The formula for the z-sore is
x - mean
z = ----------------------
(std dev)
In this case let's multiply both sides by (std dev), obtaining:
x - mean = z*(std dev).
Solving for (mean), we get
mean = x - z*(std dev)
Substituing 37 for x, 2.4 for z and 2.5 for (std dev), we get:
mean = 37 - (2.4)(2.5) = 31
The mean temperature is 31.
Final answer:
To find the mean temperature with the given z-score and standard deviation, the z-score formula is used. After calculation, the mean temperature in Philadelphia for the first 15 days of February is determined to be 31°.
Explanation:
The question is asking us to find the mean temperature in Philadelphia for the first 15 days in February, given that the daily high temperatures are normally distributed with a standard deviation of 2.5° and that on Valentine's Day (February 14th), the temperature was 37° with a z-score of 2.4. To solve for the mean temperature, we can use the z-score formula:
Z = (X - μ) / σ
Where:
Z is the z-score,
X is the value in the dataset,
μ is the mean, and
σ is the standard deviation.
We know Z = 2.4, X = 37°, and σ = 2.5°. Plugging these values into the z-score formula, we can solve for the mean (μ).
2.4 = (37 - μ) / 2.5
Multiplying both sides by 2.5, we get:
2.4 x 2.5 = 37 - μ
6 = 37 - μ
μ = 37 - 6
μ = 31°
Therefore, the mean temperature in Philadelphia for the first 15 days in February is 31°.

Solve the inequality.
8+8(x + 4) >32
The solution is
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
Inequality Form: x > - 1
Step-by-step explanation:
Answer:
x > -1
Step-by-step explanation:
To solve, we must isolate the variable, x
8+8(x + 4) >32
Distribute the 8
8+ 8*x +8*4
8+8x+ 32 >32
Combine like terms
8+32 +8x >32
40 + 8x >32
Subtract 40 from both sides
8x > -8
Divide both sides by 8
x > -1

Quadrilateral RSTV is a rectangle, and the diagonal intersect at W. Find the value of X and Y.
Answer:
x = 3
y = 14
Step-by-step explanation:
VR = TS VT = RS (Rectangle)
y = x + 11
y - 3x = x + 2
y = 4x + 2
x + 11 = 4x + 2
3x = 9
x = 3
y = 14

Solve the equation for all real values of x. 3tan^2x=3tanx
The equation 3tan²x = 3tanx solved for all real values of x is [tex]x = n\pi[/tex] or [tex]x = \dfrac{\pi + 4n\pi}{4}[/tex], where n is an integer
Solving the equation for all real values of x.
From the question, we have the following parameters that can be used in our computation:
3tan²x = 3tanx
This can be expressed as
3tan²x - 3tanx = 0
Factor out 3tanx
3tanx(tanx - 1) = 0
Expand
3tanx = 0 or tanx - 1 = 0
So, we have
tanx = 0 or tanx = 1
Take the arctan of both sides
x = tan⁻¹(0) or x = tan⁻¹(1)
Evaluate the arctan for all real values of x.
[tex]x = n\pi[/tex] or [tex]x = \dfrac{\pi + 4n\pi}{4}[/tex], where n is an integer
Luisa Díaz drove her vehicle about 7,200 miles last year. Her fixed costs totaled $1,058.40 and her variable costs were $1965.60 how much did it cost per mile
Answer:
$0.42
Step-by-step explanation:
Given:
Luisa Díaz drove her vehicle about 7,200 miles last year.
Total fixed cost = $1,058.40
Total variable cost = $1965.60
Question asked:
How much did it cost per mile ?
Solution:
Total cost of driving 7200 miles = Total fixed cost + Total variable cost
= $1,058.40 + $1965.60
= $3024
By unitary method:
Cost of driving 7200 miles = $3024
Cost of driving 1 mile = $3024 [tex]\div[/tex] 7200
= $0.42
Thus, cost of driving per mile is $0.42

The points (2,10) and (minus2,minus10) are plotted on the coordinate plane using the equation yequalsatimesx. How can you use the coordinates to find the value of a? Select the correct answer below, and fill in the answer box to complete your choice. (Type a whole number.) A. The value of a is the number that the y-values are multiplied by to get to the corresponding x-values. So, aequals nothing. B. The value of a is the absolute value of the difference of the y-values. So, aequals nothing. C. The value of a is the number that the x-values are multiplied by to get to the corresponding y-values. So, aequals nothing. D. The value of a is the absolute value of the difference of the x-values. So, aequals nothing.
Answer: The value of a is the number that the x-values are multiplied by to get to the corresponding y-values. So, a equals 5
We have
y=ax
so a is clearly the number we multiply by the x values.
Substituting either points (2,10) and (-2,-10),
10 = a(2)
a = 10/2 = 5

Step-by-step explanation:
Jeremy caught 8 fish in a contest.
The mean weight of the fish was 4.3125 kg.
He forgot to make his own record of the weight of the last fish,
but the first 7 were: 4.3 kg, 5.3 kg, 6.8 kg, 2.6 kg, 3.2 kg, 4.4 kg and 4.8 kg
What was the weight of the last fish?
kg [2]
The weight of the last fish was 3.1 kg. It's found by subtracting the sum of the weights of the first 7 fish from the sum of all weights.
To find the weight of the last fish, we can use the mean weight formula:
[tex]\[\text{Mean weight} = \frac{\text{Sum of all weights}}{\text{Number of fish}}\][/tex]
Given:
- Jeremy caught 8 fish.
- The mean weight of the fish was 4.3125 kg.
- The sum of the weights of the first 7 fish is [tex]\(4.3 + 5.3 + 6.8 + 2.6 + 3.2 + 4.4 + 4.8\).[/tex]
First, let's calculate the sum of the weights of the first 7 fish:
[tex]\[4.3 + 5.3 + 6.8 + 2.6 + 3.2 + 4.4 + 4.8 = 31.4\text{ kg}\][/tex]
Now, let's find the sum of all weights of the 8 fish:
[tex]\[4.3125 \times 8 = 34.5\text{ kg}\][/tex]
To find the weight of the last fish, we subtract the sum of the weights of the first 7 fish from the sum of all weights:
[tex]\[34.5 - 31.4 = 3.1\text{ kg}\][/tex]
So, the weight of the last fish was 3.1 kg.

Step-by-step explanation:
Average rooms cleaned per housekeeper day: The average number of rooms cleaned per housekeeper day is performance ratio that gives an idea of how many rooms each housekeeper cleaned.
Average rooms cleaned per housekeeper day = [tex]\frac{ Number of rooms occupied}{Number of full-time housekeepers}[/tex]

Find the value of two numbers if their sum is 5 and their difference is 30
Answer:
The 2 numbers are -12.5 and 17.5.
Step-by-step explanation:
Let 1 number be x then x - y = 30 where the other number is y.
y = x - 30 so the sum is:
x - 30 + x = 5
2x = 35
x = 17.5
and y = 17.5 - 30 = -12.5.
Answer:
17.5 and -12.5

Emilce pide 5 platos por semana para almorzar en la oficina. El menú ofrece 5 opciones diferentes. De cuantas maneras puede realizar el pedido de la semana si quiere repartir los platos?
Answer:
120 different ways
Step-by-step explanation:
For the first lunch, Emilce has 5 options to choose,
In the second lunch, now she has only 4 options, as one was already chosen.
Then, in the third lunch, she has 3 options.
In the fourth lunch, she has 2 options.
In the last lunch, she has just 1 option.
So, the number of different ways she can order her lunches in the week is:
5 * 4 * 3 * 2 * 1 = 120
She can order in 120 different ways.
