Plz helpmeee The total cost after tax to repair Deborah’s computer is represented by 0.07(80h)+80h, where h represents the number of hours it takes to repair Deborah’s computer. What does each part of the expression represent? a. 80 b. 80h c. 0.07 d. 0.07(80h) e. If it took 3.5 hours to repair the computer, how much would Deborah have to pay including tax?

a. hourly rate

b. the cost before the tax

c. tax rate

d. tax amount

e. 299.6

Step-by-step explanation:

When you look at the formula, since h represents the number of hours and it is multiplied with 80, you can tell that 80 is the hourly rate. This is how you would calculate the cost if there was no tax. Also, you can see that it is also multiplied with 0.07, that implies 0.07 is the tax rate and 0.07(80h) is the tax amount.

Since h represents the number of hours in the given formula:

→ 0.07(80h)+80h = 0.07(80(3.5)) + 80(3.5) = 19.6 + 280 = 299.6

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
