Answer:
Step-by-step explanation:
On the return trip from the beach, you pedal hard for the first ten minutes and cover 4 miles.
Speed = distance covered/time taken
This means that your speed for the first 4 miles would be
4/10 = 0.4 miles per minute
Tired, you slow down and cover the last 6 miles in 36 minutes. This means that your speed for the last 6 miles would be
6/36 = 0.17 miles per minute
Therefore, your average speed for the return trip would be
(0.4 + 0.17)/2
= 0.285 miles per minute
Answer:
volume of the sphere is V=1766.25 
Step-by-step explanation:
step:1
<u>The volume of the sphere formula is V=
</u>
<u>step:2</u>
Given radius of the sphere r=7.5 ft
substitute given radius r=7.5 ft value in volume of the sphere formula
![V=[tex]\frac{4 pi r^{3} }{n}](https://tex.z-dn.net/?f=V%3D%5Btex%5D%5Cfrac%7B4%20pi%20r%5E%7B3%7D%20%20%7D%7Bn%7D)
\\
V=\frac{4(3.14)(7.5)^{3} }{3}[/tex]
V=1766.25
Final answer is V=1766.25

Answer:
5.1
Step-by-step explanation:
-44.288-31.6 / -3.1(6-1.2)
Add -44.288 and -31.6
= -75.888 / -3.1(6-1.2)
Subtract 1.2 from 6
= -75.888 / -3.1(4.8)
Multiply -3.1 and 4.8
= -75.888 / -14.88
Divide -75.888 by -14.88
-75.888 / -14.88
=5.1
