Answer: D. 14.1 cubic inches
Step-by-step explanation:
Formula for volume of a sphere: 4/3 x pi x radius cubed
Substitute: 4/3 x pi x 1.5 cubed
= 14.1
L = A/W
L = 72a³b⁴ / <span>6a²b
L = 12 a b</span>³
1hr=60mins
1min=60seconds
1hour=60*60=3600seconds
ratio and proportaion
distance/time=distance/time
39/7=x/3600
times both sides by (7*3600)
140400=7x
divide both sides by 7
20057 and 1/7=x
answer is 20057 and 1/7 meters per hour
or
20.0571428km per hour
Answer:
See below.
Step-by-step explanation:
Formula:
![a_n = 3(n + 4)](https://tex.z-dn.net/?f=%20a_n%20%3D%203%28n%20%2B%204%29%20)
First term: n = 1
![a_1 = 3(1 + 4) = 15](https://tex.z-dn.net/?f=%20a_1%20%3D%203%281%20%2B%204%29%20%3D%2015%20)
Second term: n = 2
![a_2 = 3(2 + 4) = 18](https://tex.z-dn.net/?f=%20a_2%20%3D%203%282%20%2B%204%29%20%3D%2018%20)
Third term: n = 3
![a_3 = 3(3 + 4) = 21](https://tex.z-dn.net/?f=%20a_3%20%3D%203%283%20%2B%204%29%20%3D%2021%20)
Fourth term: n = 4
![a_4 = 3(4 + 4) = 24](https://tex.z-dn.net/?f=%20a_4%20%3D%203%284%20%2B%204%29%20%3D%2024%20)
Tenth term: n = 10
![a_{10} = 3(10 + 4) = 42](https://tex.z-dn.net/?f=%20a_%7B10%7D%20%3D%203%2810%20%2B%204%29%20%3D%2042%20)
