Mathematics
1 answer:
ladessa [460]3 years ago

Answer:

D

Step-by-step explanation:

The line x originates from the center of the circle and forms a perpendicular line with line RS, which means that the line is bisected.

That means that line RT is half of line RS, or 7.

Then we can use the Pythagorean Theorem to find the measure of x.

7^2+b^2=9^2

49+b^2=81

b^2=32

b = √32

b ≈ 5.66

kirill [66]

Answer:

<h3>A. 1 hour</h3>

Step-by-step explanation:

If one cleaning company's cost can be calculated by the expression 75 + 50x, where x is the amount of hours they spend cleaning and another cleaning company's cost can be calculated using the expression 50 + 75x, then to calculate how long each company will have to clean to cost the same amount, we will equate both expression of the company cost and solve for x as shown;

On equating:

75 + 50x,  =  75x + 50

collect like terms'

50x-75x = 50-75

-25x = -25

divide both sides by -25

-25x/-25 = -25/-25

x = 1

hence the number of hours each company will have to clean to cost the same amount is 1 hour
