Answer:
Step-by-step explanation:
Let y be the amount of water in the bottle x seconds after the faucet was turned on.
We have been given that the gauge on the bottle indicates that it contains 19 ounces of water after it has been filling for 5 seconds. After it has been filling for 11 seconds, the gauge indicates the bottle contains 37 ounces of water.
We have two points on the line 
and 
.
Let us find slope of the line passing through these points.
We will write our required equation in slope-intercept form 
, where, m represents slope and b represents the y-intercept.
Let us find y-intercept by substituting and coordinates of point in slope intercept form.
Therefore, our required equation would be .
Many people would say "one point six seven" or "one dot six seven".
But technically, it's "<em>one and sixty-seven hundredths</em>".
Answer:
(D) 30pi inches
Step-by-step explanation:
First, we use the given volume, the given height, and the formula of the volume of a cylinder to find the radius of the base. Then we use the radius of the base to find the circumference of the base.
We set the formula equal to the volume and replace h with 30 in.
Divide both sides by 30pi in.
Take the square root of each side.
The radius of the base is 15 in.
Now we use the radius of the base and the formula of the circumference of a circle to find the answer.
