Step-by-step explanation:
Given:
156 $ to United way for a year.
With each weeks.
To Find:
How much amount he will take for pay for giving to United way.
Solution:
He wants to give money to united way in a year
So there are 365 days per year
And he held money from is his pay every week
So there 7 days per weeks.
Hence Total number of weeks in a year will given by,
=365/7
=52 weeks per year
Now he held every week from his pay to United way
And Total amount to distribute is about 156 $ in 52 weeks.
So Every week amount will be
=156$/52
=3 $ /week
Final answer:
To donate $156 to United Way over a year, Philip needs to have $3 withheld from his savings each week.
Explanation:
To calculate the amount Philip will need to have withheld every week to give $156 to United Way over a year:
First, find the number of weeks in a year (52 weeks).
Divide the total amount to be donated ($156) by the number of weeks in a year to find the weekly amount: $156 ÷ 52 = $3.
Therefore, Philip will need to have $3 withheld from his savings each week to donate $156 to United Way over a year.

The answer to your question is below
Step-by-step explanation:
Data
Right triangle
hypotenuse = 24
Opposite side = 15
Adjacent side = ?
Process
1.- Calculate the adjacent side using the Pythagorean theorem.
hypotenuse² = opposite side² + adjacent side²
-Solve for adjacent side
Adjacent side² = hypotenuse² - opposite side²
-Substitution
Adjacent side² = 24² - 15²
-Simplification
Adjacent side² = 576 - 225
Adjacent side = 351
-Result
Adjacent side = 18.73°
2.- Find the value of x°
a) Using sin x
sinx = Opposite side/Hypotenuse = 15/24 = 0.625
x = 38.68°
b) Using cos x
cos x = Adjacent side/Hypotenuse = 18.73/24 = 0.78
cos x = 38.68°
c) Using tan x
tanx = Opposite side / Hypotenuse = 15/18.73 = 0.80
tan x = 38.68°
The coordinates of point A on a grid are (2, -5). Point A is reflected across the x-axis to obtain point B. The coordinates of point B are (2, ___). (1 point)
Answer:
(2,5)
Step-by-step explanation:
If you are flipping a point over the x-axis, multiply the y coordinate by -1, if you are flipping something over the y-axis, multiply the x coordinate by -1.
The coordinates of point B are (2,5)
How does reflection across axis work?When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If you study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
Given that coordinates of point A on a grid are (2, -5). Point A is reflected across the x-axis to obtain point B.
Since flipping a point over the x-axis, then we have to multiply the y coordinate by -1,
And ifyou are flipping something over the y-axis, then we have to multiply the x coordinate by -1.
Therefore, the point B are (2, _5_).

The playground of a school has areas fixed for various activities. One-fifth of the playground is used for students to sit and read. Of the remaining playground, is used for playing soccer. The rest of the playground is used for playing basketball. Which equation represents the part of the playground used for soccer?
Answer:
2/3* 4/5 = 8/15
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached file below.
Given:
One-fifth (1/5) of the playground is used for students to sit and read2/3 is used for playing soccer The rest of the playground is used for playing basketballSo assume that the the playground is divided into 5 equal part
=> 1 part is used for students to sit and read or (1/5)
=> the remaining equal part is 4 or (4/5)
Because 2/3 of the remaining part is used for playing soccer
=> the equation represents the part of the playground used for soccer is:
2/3 of 4/5
= 2/3* 4/5
= 8/15
To find the part of the playground used for soccer, remember one-fifth is for reading, leaving four-fifths. Then, calculate three-quarters of the remaining area for soccer.
To represent the part of the playground used for soccer, we need to consider that one-fifth of the playground is used for students to sit and read. Therefore, the remaining four-fifths of the playground is available for other activities. Since three-quarters of the remaining playground is used for playing soccer, the equation representing the part of the playground used for soccer is:
4/5 * 3/4 = 12/20 = 3/5
What is the length of the diagonal of a 10 cm by 15 cm rectangle?
Answer:
18.02 cm
Step-by-step explanation:
A diagonal makes a rectangle into two right triangles. So if we use the Pythagorean theorem we can find the hypotenuse which is the diagonals.
Remember, because we know the length and width, we know the two sides.
10^2 + 15^2 = c^2
100+225 = c^2
325 = c^2
18.027 ≈ c
We can use the Pythagorean theorem to solve for the diagonal. The diagonal is the same as the hypotenuse of a triangle.
Pythagorean Theorem: a² + b² = c²
Now, solve for the diagonal.
(10)² + (15)² = c²
100 + 225 = c²
325 = c²
√325 = √c²
18.0277... = c
Round if necessary.
18.0277... = 18.03
Therefore, the diagonal of the rectangle is approximately 18.03cm.

Which expression is equivalent to 3(7x – 5)?
Answer:
21x-15
Step-by-step explanation:
Use the distributive property:
3×7x=21x
3×5=15
Don't forget the - sign!!!
So,
3(7x - 5) = 21x - 15
Final answer:
The expression 3(7x - 5) using the distributive property is equivalent to 21x - 15, which is obtained by multiplying 3 by each term inside the parenthesis.
Explanation:
The expression 3(7x
- 5) is equivalent to 21x - 15. This process is known as the distributive property, where you multiply the number outside the parenthesis by each term inside the parenthesis. Let's break it down step by step:
Multiply the first term inside the parenthesis by 3: 3 ×7x = 21x.
Multiply the second term inside the parenthesis by 3: 3 ×(-5) = -15.
Combine these results to get the equivalent expression: 21x - 15.
Given f(x)=-5x+1 find f(6)
Answer:
f(6)=-29
Step-by-step explanation:
f(6)=-5(6)+1
f(6)=-30+1
f(6)=-29
The value of f(6) is -29.
Given,
f(x)= -5x+1
We need to find f(6).
How do we solve a function at a point?A function is denoted by f(x) and the point can be a value of x.
The x values are called domain and f(x) is called the output.
Example:
f(x) = x + 2
At x = 1
f(1) = 1 + 2 = 3.
Find f(x) = -5x + 1 at x = 6.
f(x) = -5x + 1
f(6) = - 5 x 6 + 1
= -30 + 1
= -29
This means the function f(x) is -29 at x = 6.
Thus the value of f(6) is -29.

What is the interval estimate for the proportion that would fail in the form
(lower limit, upper limit)?
Answer:
(Lower limit, Upper limit) = (0.10, 0.14)
(Lower limit, Upper limit) = (10%, 14%)
Step-by-step explanation:
Total number of cars = 150
Cars that failed the safety inspection = 18
The proportion is given by
p = 18/150
p = 0.12
p = 12%
The confidence interval is given by
p ± margin of error
Where margin of error is 0.02
0.12 ± 0.02
Lower limit = 0.12 - 0.02
Lower limit = 0.10
Lower limit = 10%
Upper limit = 0.12 + 0.02
Upper limit = 0.14
Upper limit = 14%
(Lower limit, Upper limit) = (0.10, 0.14)
(Lower limit, Upper limit) = (10%, 14%)
Answer:

Explain why P(AD) and P(DIA) from the table below are
not equal.
Answer:
P(A) ≠ P(D)
Step-by-step explanation:
P(A|D) = P(AD)/P(D)
P(D|A) = P(AD)/P(A)
The two denominators are not equal, so the quotients cannot be equal.
P(A|D) and P(D/A) are not equal because the total number of A and D are not equal.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
From the table, we have the following parameters:
n(A) = 8
n(D) = 10
n(A and D) = 2
P(A|D) and P(D|A) are both conditional probabilities, and they are calculated using:
P(A|D)=2/10
=1/5 = 0.2
P(D/A)= 2/8
=1/4
From the above computations, we have:
P(A|D)≠P(D/A)
Hence, P(A|D) and P(D/A) are not equal because the total number of A and D are not equal.

Step-by-step explanation:
The generic equation for a movement with constant acceleration is:
S = So + Vo*t + (a*t^2)/2
Where S is the final position, So is the inicial position, Vo is the inicial speed, a is the acceleration and t is the time.
If we compare with our equation (where x is the time and f(x) is the final distance), we have that:
So = 34.3
Vo = 29.4
a = -9.8
So we have that the inicial position (So) of the object is 34.3 meters

Find the volume of a right circular cone that has a height of 9.1 m and a base with a circumference of 12.1 m. Round your answer to the nearest tenth of a cubic meter.
Answer:
[tex]V=35.3\ m^3[/tex]
Step-by-step explanation:
-Given the cone's height is 9.1m and the Circumference is 12.1
#We use the circumference formula to calculate the radius:
[tex]C=2\pi r\\\\12.1=2\pi r\\\\r=\frac{12.1}{2\pi}=\frac{6.05}{\pi}\ cm[/tex]
-The volume of the cone using the radius above can then be calculated as follows:
[tex]V=\pi r^2\frac{h}{3}\\\\=\pi\times(\frac{6.05}{\pi})^2\times \frac{9.1}{3}\\\\\\=35.3\ m^3[/tex]
Hence, the cone's volume is [tex]35.3\ m^3[/tex]
