Answer:

5) 140.8m^2 6) 360in^2

Step-by-step explanation:

6.4 x 6.4 = 40.96

(7.8 x 6.4) ÷ 2 = 24.96

24.96 x 4 = 99.84

99.84 + 40.96 = 140.8m^2

12 x 10 = 120in

13 x 10 = 130in

5 x 10 = 50in

(12 x 5) ÷ 2 = 30in

30 x 2 = 60in

60 + 50 + 130 + 120 = 360in^2

1800 * 5.5 = 9900

Answer: <u>A light bulb consumes 9900 watt-hours each 5 days and 12 hours</u>.

Answer:

Step-by-step explanation:

A radius to the tangent point always forms a right angle with the tangent:

m∠XWY = 90°

So:

90° + 58° + x - 7° = 180°

141° + x = 180°

x = 39°
