Apainting contractor paints with a brush at a rate of 192 square feet per hour. using a paint sprayer, she is able to cover 576 square feet per hour. she has a contract to paint a house with 1632 square feet of wall surface and 2400 square feet of ceiling space. she estimates she has 3 hours of brushwork to perform. how many hours will she need to use the sprayer in order to complete the job?

Hi there,

2400 + 1632 = 4032

3 * 192 = 576

4032 - 576 =>

3532 - 76 =>

3532 + 24 - 76 - 24

3556 - 100

3456

3456 / 576 => 6

Therefore, 6 hours of sprayer work

Hope this helps!

Sincerely,

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
