Answer:
The size of the tank is 16 gallons
Step-by-step explanation:
Here, we want to calculate the size of the gas tank of the truck
we simply divide the total amount spent by the price per gallon
Mathematically, that will be;
53.28/3.33 = 16 gallons
Answer:
D. 10
Step-by-step explanation:
To find the slope of the equation, we first need to put the equation into slope-intercept form:
y=mx+b
So first, we need to get y by itself.
10x-y=2
Subtract 10x from both sides.
-y=-10x+2
Then, divide -1 on both sides.
y=10x-2
Slope=10
Answer:
Radius of the sphere = ![\sqrt[3]{91.13} \,feet](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B91.13%7D%20%5C%2Cfeet)
Step-by-step explanation:
Volume of a sphere is :
For, Volume = 
As, 
![121.5\times \pi =\dfrac{4}{3}\times \pi \times r^3 \\\\121.5=\dfrac{4}{3}\times r^3\\\\ 121.5\times \dfrac{3}{4} =r^3\\\\r^3=91.13\\\\r=\sqrt[3]{91.13} \,feet](https://tex.z-dn.net/?f=121.5%5Ctimes%20%5Cpi%20%3D%5Cdfrac%7B4%7D%7B3%7D%5Ctimes%20%5Cpi%20%20%5Ctimes%20r%5E3%20%5C%5C%5C%5C121.5%3D%5Cdfrac%7B4%7D%7B3%7D%5Ctimes%20r%5E3%5C%5C%5C%5C%20121.5%5Ctimes%20%5Cdfrac%7B3%7D%7B4%7D%20%3Dr%5E3%5C%5C%5C%5Cr%5E3%3D91.13%5C%5C%5C%5Cr%3D%5Csqrt%5B3%5D%7B91.13%7D%20%5C%2Cfeet)
