Answer:
Exact answer = 10.41666666666666666666666666666pi
Estimated answer = 32.70938
Step-by-step explanation:
Semi circle formula: 1/2 * 4/3 * pi * r^3
r = 2.5
1/2 * 4/3 * pi * 2.5^3
2/3 * pi * 2.5^3
2/3 * pi * 15.625
10.416..... * pi
Exact answer = 10.417pi
We can estimate pi as 3.14
So, 10.417 * 3.14 = 32.70938
Exact answer = 10.41666666666666666666666666666pi
Estimated answer = 32.70938
Answer:
120 + 3.5x≤ 190
Step-by-step explanation:
Add up all the costs
80+ 10+10+20 + 3.50x where x is the number of cupcakes
Combine like terms
120 + 3.5x
This must be less than or equal to 190
120 + 3.5x≤ 190
Answer:
22.05 minutes
Step-by-step explanation:
7.2 + 7.35 + 7.5 = 22.05 minutes
If a function has roots -1 and -5, it must be in the form

We can fix the coefficient a by imposing the passing through (0,-30):

So, the function is

16(3b−0.25)
=(16)(3b+−0.25)
=(16)(3b)+(16)(−0.25)
=48b−4
