Aplumber charges $25 for a service call plus $50 per hour of service. write an equation in slope intercept form for the cost, c, after h hours of service. what will be the total cost for 8 hours of work? 10 hours of work?

8 hour cost $425   10 hour cost $525

Step-by-step explanation:

multiply 8 by 50 then add 25=425

multiply 10 by 50 then add 25=525

(8×50)+25=425

(10×50)+25=525

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
