Mr king is going to paint his house. The paint costs 21.99$ a gallon or 93.65$ for a 5 gallon can. What would be the unit price
vampirchik [111]
Divide 93.65 by the 5 gallons.

93.65/5= 18.73

If me.king bought the larger container, the unit price would be $18.73 per gallon. 

21.99-18.73= 3.26

The savings is $3.26 per gallon.

I hope this helps!

A pair of shoes are on sale for 25% off their regular price of $180. Students at Pikesville Middle can get an additional 10% off
Nikolay [14]

Answer:

$121.5

Step-by-step explanation:

$180 × 0.25 = $45 <-- because it is a discount, we will subtract

$180 - $45 = $135 <-- price with 25% discount

$135 × 0.10 = $13.5

$135 − $13.5 = $121.5

One brand of coffee is packaged in cylinders where the height is equal to the radius, r. The volume of the package, in cubic cen
aliya0001 [1]

Answer:

<h2>C(V(r)) = 3.2πr3</h2>

Step-by-step explanation:

This problem is a composition of function defined by C(V(r)), now we have the functions V(r)= \pi r^{3} and C(V)=3.2V, where the first depends on the radius, and the second dependes on the volume, that means, to find the number of ounce of coffe, we need to determine the volume of the cylinder, that's why we have to replace the volume function inside the ounces function,

C(V(r))=3.2(\pi r^{3} )

Therefore, the right answer is the last choice.
