You are buying 12-packs of Mountain Dew for $\text{4.50}4.50 each and have a gift card worth $77. The function m\left(x\right)=4

poizon [28]

Answer:

$191

Step-by-step explanation:

The function is given by :

m(x) = 4.50x-7 ...(1)

Where

m(x) is the total cost if you buy x 12 packs of Mountain Dew.

We need to find the cost you pay to buy 44 12-packs of Mountain Dew

Put x = 44 in equation (1), we get :

m(x) = 4.50(44)-7

m(x) = 198-7

m(x) = $191

Hene, the cost for 44 12- packs of Mountain Dew is $191.

A square pyramid has a base with a side length of 7.5 feet and lateral faces with heights of 16 feet.What is an expression that

Goryan [66]

Answer:

$SA=592.50\text{ ft}^2$

Step-by-step explanation:

We have been given that a square pyramid has a base with a side length of 7.5 feet and lateral faces with heights of 16 feet. We are asked to find the surface area of the square pyramid.

We will use surface area of square pyramid to solve our given problem as:

$SA=2a^2+4ah$ , where,

a = Length of each side of base,

h = Height of lateral face.

Upon substituting our given values in above formula, we will get:

$SA=2(7.5\text{ ft})^2+4(7.5\text{ ft})(16\text{ ft})$

$SA=2(56.25\text{ ft}^2)+480\text{ ft}^2$

$SA=112.5\text{ ft}^2+480\text{ ft}^2$

$SA=592.50\text{ ft}^2$

Therefore, the surface area of the given square prism would be 592.50 square feet.
