Let the equation C = 2.32 N + 34,180 represent the cost of raising a child, C, on an income, N.
If the Murphy family has an annual income of $60,000, what is the expected cost of raising a child?
$172,460
$173,380
$175,620
$176,980
Answer:
173,380
Step-by-step explanation:
just took the test and got it right
The expected cost of raising a child is $173,380.
Given,
C = 2.32 N + 34,180.
C represents the cost of raising a child.
N represents the income.
If the Murphy family has an annual income of $60,000.
We are to find the expected cost of raising a child using the given equation.
We have,
C = 2.32 N + 34,180________(A)
Now,
If the Murphy family has an annual income of $60,000.
N = $60,000___________(B)
Putting (B) in (A).
C = 2.32 x $60,000 + 34,180
C = 139,200 + 34,180
C = $173,380.
Thus the expected cost of raising a child is $173,380.

Answer:
-1.5
Step-by-step explanation:
4x - 36 = 36 + 52x
We can make this into another equation.
72 + 52x = 4x
4x - 52x = -48x
-48x = 72
48x = -72
x = -72/48 = -1.5
Pls do mark me as brainliest.Thanks! ;)
Answer:
x = - [tex]\frac{3}{2}[/tex] = - 1.5
Step-by-step explanation:
Given
4(x - 9) = 4(9 + 13x) ← distribute parenthesis on both sides
4x - 36 = 36 + 52x ( subtract 52x from both sides )
- 4x - 36 = 36 ( add 36 to both sides )
- 4x = 72 ( divide both sides by - 4 )
x = [tex]\frac{72}{-4}[/tex] = - [tex]\frac{3}{2}[/tex] = - 1.5

Answer:
x=45
Step-by-step explanation:
Because angles TRS and TRV are a linear pair, their two angle measures must add up to 180 degrees. Therefore:
x+3x=180
4x=180
x=180/4=45 degrees
Hope this helps!

45
Step-by-step explanation:
its a strait line so both of those angles are equal too 180 deg.

Which graph shows a rate of change of one-half between –4 and 0 on the x-axis? On a coordinate plane, a straight line with a positive slope crosses the x-axis at (6, 0) and the y-axis at (0, 3). Solid circles appear on the line at (negative 4, negative 1), (0, 3). On a coordinate plane, a parabola opens up. It goes through (negative 5.25, 4), has a vertex of (0, negative 3), and goes through (5.25, 4). Solid circles appear on the parabola at (negative 4, 1), (0, negative 3). On a coordinate plane, a parabola opens down. It goes through (negative 5.5, negative 4), has a vertex of (0, 4), and goes through (5.5, negative 4). Solid circles appear on the parabola at (negative 4, 0), (0, 4). On a coordinate plane, a curved line opens up and left in quadrant 2. It is asymptotic to the negative x-axis and positive y-axis. Solid circles appear on the line at (negative 4, 0.25), (0, 4).
Answer:
First option
Step-by-step explanation:
There is a mistake in the description of the first function.
On a coordinate plane, a straight line with a positive slope crosses the x-axis at (-6, 0) and the y-axis at (0, 3). Solid circles appear on the line at (-4, 1), (0, 3).
Given two points of a function, (x1, y1) and (x2, y2), its rate of change between them is:
Rate of change: (y2 - y1)/(x2 - x1)
Points of the 1st graph: (-4, 1), (0, 3).
Rate of change: (3- 1)/(0 - (-4)) = 1/2
Points of the 2nd graph: (-4, 1), (0, -3).
Rate of change: (-3 - 1)/(0 - (-4)) = -1
Points of the 3rd graph: (-4, 0), (0, 4).
Rate of change: (4 - 0)/(0 - (-4)) = 1
Points of the 4th graph: (-4, 0.25), (0, 4).
Rate of change: (4 - 0.25)/(0 - (-4)) = 0.9375

Michael made a spinner to use in a game. He tested the spinner by spinning it 4 times. The pointer landed on 1 each time. What do these results suggest about the spinner?
A. It is probably a fair spinner. The probability of spinning a “1” is 0.25.
⊝
B. It is probably a fair spinner. The probability of spinning a “1” 4 times is 0.25 × 4, which equals 1.
⊝
C. It is probably not a fair spinner. The probability of spinning a “1” on all 4 spins is about 0.004.
⊝
D. It is probably not a fair spinner. The probability of spinning a “1” on all 4 spins is less than 0.0001.
Please help
Answer:
C
Step-by-step explanation:
If The probability of spinning a “1” is 0.25, then the probability of spinning 4 ones is:
0.25*0.25*0.25*0.25 = 0.25^4 ≈ 0.004
(the four events are independent)
The pointer landed on 1 each time, which probability is very low. So, we can conclude that the spinner is not fair.

Step-by-step explanation:
Take away the negative signs:
-80/-20

Now, divide normally.
80 ÷ 20 = 4
Since a negative number divided by another negative number is positive, the quotient is still 4.
Therefore, the simplified fraction is 4.

1. There were 144 people in attendance at the school football game last Friday. This week there were 346 people in attendance at the school football game.What is the percent of change from last week to this week?Round your answer to the nearest whole number
Answer:
percentage change ≈ 140%
Step-by-step explanation:
There were 144 people in attendance at the school football game last Friday. This week there were 346 people in attendance at the school football game.What is the percent of change from last week to this week?Round your answer to the nearest whole number
To calculate the percentage change, we will follow the steps below:
First, we will find the difference(that is increase) between 144 and 346
Increase = New number - Original number
= 346 - 144
= 202
Next is to divide the increase which is 202 by the original number which is 144 and then multiply by 100
That is;
percentage change = increase ÷ original number × 100
=202 / 144 × 100
≈ 140 to the nearest whole number
percentage change ≈ 140 %
Line segment AB was dilated to create line segment A'B' using the dilation rule DQ,0.15.
What is x, the distance between points A and A'?
2.4 units
4.8 units
13.6 units
14.4 units
Answer:
13.6
Step-by-step explanation:
The measure of the segment AQ is related to the measure of the segment A'Q by the dilation factor as follows:
dilation factor = A'Q/AQ
AQ = A'Q/dilation factor
Replacing with data:
AQ = 2.4/0.15 = 16
Then, the distance between points A and A' is
x = 16 - 2.4 = 13.6
The distance between points A and A' is 13.6 units
Dilation of coordinatesDilation is a way of changing the position of an image on an xy-plane.
The measure of the segment AQ is related to the measure of the segment A'Q by the dilation factor. Hence'
scale factor = A'Q'/AQ
Given the following
A'Q' = 2.4
Scale factor = 0.15
Substitute
AQ = 2.4/0.15
AQ = 16
x = 16 - 2.4
x = 13.6
Hence the distance between points A and A' is 13.6 units
