Gaming systems are on sale for 20% off the original price (g), which can be expressed with the function p(g) = 0.8g. Local taxes are an additional 12% of the discounted price (p), which can be expressed with the function c(p) = 1.12p. Using this information, which of the following represents the final price of a gaming system with the discount and taxes applied?c(p) + p(g) = 1.92g c[p(g)] = 0.896g g[c(p)] = 1.92p c(p) ⋅ p(g) = 0.896pg

John and 3 friends are going out for pizza for lunch. They split one pizza and 4 large drinks. The pizza cost $13.00. After using a $6.00 gift certificate, they spend a total of $13.20. Write an equation to model this situation, and find the cost of one large drink. A. 4d – $13.00 + $6.00 = $13.20; $6.73

B. 4d + $13.00 – $6.00 = $13.20; $1.55

C. 4d + $13.00 – $6.00 = $13.20; $1.60

D. 3d + $13.00 – $6.00 = $13.20; $2.07

Answers

If John and 3 friends ordered pizza for $13.00 and they paid $13.20 where in they also used the $6.00 gift certificate. Then we can deduce that the total amount of the bill was $13.20 + the gift certificate which is $6.00 which is equal to $19.20 and since the pizza was for $13.00 then we can deduct this from the total bill to get the amount of the drinks, ergo $19.20 - $13.00 = $6.20 since there were 4 large drinks so we divide the total amount of the drinks to the number of drinks. We would have $6.20 / 4 = $1.55 / large drink.

So the answer would be:

B. 4d + $13.00 – $6.00 = $13.20:$1.55

Which pair of angles is complementary

Answers

The complementary angles are angles that add up to 90°.

It is required to find the pair of angles is complementary.

What is angle?

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle and corner whether constituting a projecting part or a partially enclosed space.

Solution:

When the sum of two angles is equal to 90° degrees, they are called complementary angles. For example, 30° and 60° ,45° and 45° ,80° and 10° are complementary angles.

Therefore, the complementary angles are angles that add up to 90°.
