We have been given that a sphere and a cylinder have the same radius and height. The volume of the cylinder is 21 meters cubed. We are asked to find the volume of the sphere.
We know that height of sphere is equal to its radius. This means that
.

Using
, we will get:


Upon comparing volume of sphere and volume of cylinder, we can see that volume of sphere is
times volume of cylinder.




Therefore, the volume of the sphere would be 28 cubic meters.
The function y = 5x has a rate of change that is in between the equation y = 4x and y = 6x.
In an equation, the rate of change is also called the slope. It is the amount that a number is increasing by. We put that value in front of the x in most equations.
In the equal that I gave, the 5 is in between the rates of 4 and 6.
Answer:
17.70-2.90=14.80
14.80/1.85=8
He could buy a maximum of 8 chip bags.
bags of chips = x
17.70-2.90/1.85≥x
Answer:

Step-by-step explanation:
Let
d ------> the number of days
c -----> the cost
we know that
The cost is equal to the number of days multiplied by $2 per day plus the initial fee of $5
The linear equation in slope-intercept form is

where
m is the slope
b is the c-intercept (value of c when the value of d is equal to zero)
in this problem we have
m=$2 per day
b=$5
substitute

It's the third one. It is the correct option.
