Answer:

  72°

Step-by-step explanation:

The external angle E is half the difference of subtended arcs CG and DF.

  E = (CG -DF)/2

  2E = CG -DF . . . . . . multiply by 2

  DF = CG -2E = 160° -2(44°) . . . . . add DF-2E to both sides; substitute values

  arc DF = 72°

Tim installs 50 square feet on his floor in 45 minutes. At this rate, how long does it take him to install 495 square feet?
Katena32 [7]

Answer:

445.5 minutes

or 7 hours 25 minutes 30 seconds

Step-by-step explanation:

We can use ratio's to solve

50 ft^2           495 ft^2

--------------  = ------------

45 minutes    x minutes

Using cross products

50x = 45*495

50x=22275

Divide each side by 50

50x/50 = 22275/50

x =445.5

445.5 minutes

If we want to convert to hours and minutes, divide by 60

7 hours is 420 minutes

445.5 -420 = 25.5

7 hours 25 minutes

.5 minutes is 30 seconds

7 hours 25 minutes 30 seconds

Marge Torelli is a pilot. Her annual group insurance costs $4,400 and her company pays 80% of the cost. How much does Marge pay
kondor19780726 [428]

The insurance company pays 80% of $4,400:
0.8*4400 = $3520

Therefor the amount Marge pays is 4400 - 3520 = $880

Note however that $4400 is the cost of annual group insurance, so to find how much she pays monthly we need to divide the amount she pays in one year by 12:
880/12 = $73.33 (correct to two decimal places)
