Define x:
----------------------------------------------------
Let the number of hours be x.
----------------------------------------------------
Construct inequality:
----------------------------------------------------
37 + 6.7x < 97.30
----------------------------------------------------
Solve x:
----------------------------------------------------
37 + 6.7x < 97.30
----------------------------------------------------
Take away 37 from both sides:
----------------------------------------------------
6.7x < 60.30
----------------------------------------------------
Divide by 6.7 through:
----------------------------------------------------
x < 9 hours

Answer:
Step-by-step explanation:
m∠3 = 18°
m∠1 = 90° - 18° = 72°
m∠2 = 180° - 2(72°) = 36°
m∠4 = 2(72°) = 144°
Answer:
70%
Step-by-step explanation:

Check the picture below.
notice, if we start checking its pattern from the 10th unit, backwards, it begins to repeat at the unit 4, namely, every 6 units.
