A cement truck pours cement into a container in the shape of a cylinder with a radius of 4 feet. The heighth of the cement in the container increases at a rate of approximately 10 inches per minute. Write an equation that models the volume V of the
cement in the container in terms of h then use the equation to determine the time at which the volume is 80 cubic feet.
Note that the volume of a cylinder is Vrh where and h are the radius and height of the cylinder

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

idk

step-by-step explanation:

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%

b.
