well if 18 out of 25 like it, then the remaining 7 doesn't like it, namely 7 out of 25.
if we take 25 to be the 100%, what is 7 off of if in percentage?
What is the volume of a sphere with a radius of 9 inches
2 answers:
Answer: 972π in.³
Step-by-step explanation: To find the volume of a sphere, start with the formula for the volume of a sphere.
Volume =
Notice that our sphere has a radius of 9 inches, so we can plug a 9 in for the radius in our formula.
Volume =
Start by simplifying the exponent. (9 in.)³ is equal to 9 inches × 9 inches × 9 inches or 729 in.³.
Volume =
Notice that we can cross cancel the 3 in 4/3 and 729 to 1 and 243.
Volume = (4) (243 in³) (π)
Volume = 972π in.³

Using the given information and what we know about linear equations, we will find the sketch below.
<h3>How to sketch a graph?</h3>Here we need to analyze each part separately.
In a coordinate axis where the y-axis represents distance and the x-axis represents time, we will have that:
First, we know that he rides for 30 minutes at a given speed, this will be represented with an increasing linear function.
Then he stops for 20 minutes, this is represented with a horizontal line.
Finally, he returns the motion, but slower than before, so the slope of this line will be smaller than the first one.
So for 0 to 30 we have an increasing linear equation, then for 30 to 50 we have a constant horizontal line, then for 50 to 80 we have another increasing linear equation
The sketch can be seen below.
