Answer:

23. 0.4583 seconds

24. 0.0107 seconds

Step-by-step explanation:

The problem statement tells you how to work it. You need to convert speed from miles per hour to feet (or inches) per second.

90 mi/h = (90·5280 ft)/(3600 s) = 132 ft/s = (132·12 in)/s = 1584 in/s

23. The time it takes for the ball to travel 60.5 ft is ...

time = distance/speed

time = (60.5 ft)/(132 ft/s) = 0.4583 s

It takes 458.3 milliseconds to reach home plate.

24. time = distance/speed

time = (17 in)/(1584 in/s) = 0.0107 s

The ball is in the strike zone for 10.7 milliseconds.

If the triangles are similar, the proportion of the legs on the left to the legs on the right will be equal. This proportion would look like:

$\frac{2x+1}{3x}=\frac{10}{14}$

(You needed to combine the orange segment and the yellow segment to find the total length of the large triangle).

Now, cross multiply and solve for x:

28x+14=30x

*Subtract 28x from both sides to isolate the variable*

14=2x

*Divide both sides by 2*

7=x

Hope this helps!!

Let the equation C= 2.32 N + 34,180 represent the cost of raising a child, C on an income, N. If the Corlone family has an incom

Answer:

$126,980

Step-by-step explanation:

Given the equation C = 2.32N + 34,180 where 'C' is the cost of raising a child and 'N' is the income. If the Corlone family has an income of $40,000, you can use this value for 'N' and solve for 'C':

C = 2.32(40,000) + 34,180

C = 92,800 + 34,180

C = $126,980
