Answer 1

Answer:

yes, it is a right triangle and ∡Q is the right angle

Step-by-step explanation:

if the slope of QR is the opposite reciprocal of QS then the two segments are perpendicular and form a 90° angle

slope of QR:  -3 - (-1) ÷ 2 - 0  = -2 ÷ 2 = -1

slope of QS:  -3 - (-1) ÷ 2 - 4  = -2 ÷ -2 = 1

-1 and 1 are opposite and reciprocal so m∡Q = 90°

Answer:

divide the cost by the amount.

4.95/5 = 0.99

8.50/10 = 0.85 (better buy)

3.59/3 = 1.20

4.99/5 = 1.00 (better buy)

1.25/16 = 0.078125

1.55/20 = 0.0775 (this one is the better buy however when you round to 2dp they are both the same price of 0.08.)

An employee at a health club takes home an after-tax salary of $950 every two weeks. If the tax rate is 8%, how much does the employee make every two weeks before taxes? Round your answer to the nearest dollar.Write an equation and explain how you used it to find your answer.

Answers

Answer:

$1032.60

Step-by-step explanation:

Given data

salary = $950 every two weeks

tax rate = 8%

let the initial pay be x

and let the pay after tax deduction be p

p= x-8/100x

Hence the equation for his pay is

[tex]p=x-0.08x-------------1[/tex]

subsitute

950=x-0.08x

950= 0.92x

divide both sides by 0.92

x= 950/0.92

x=$1032.60

The employee make $1032.60 every two weeks before taxes
