Answer:

  2 hours

Step-by-step explanation:

Time, speed, and distance are related by ...

  d = st

The distance covered is ...

  d = (60 mi/h)(3 h) = 180 mi

Then the time taken at the higher speed is ...

  180 mi = (60 mi/h +30 mi/h)(t)

  t = (180 mi)/(90 mi/h) = 2 h

The time taken at the higher speed is 2 hours.

What is the measure of angle Q to the nearest whole degree?<br> 43°<br> 49°<br> 53°<br> 58°
geniusboy [140]

Answer:

m∠Q ≈ 53°

Step-by-step explanation:

To find the measure of ∠Q, the law of cosines will need to be used. Lowercase letters represent the side lengths, while upper case letters represent angles.

In this situation, 'A' will be ∠Q. Therefore:

17² = 18² + 20² -2(18)(20)cosQ

Simplify:

289 = 324 + 400 -2(360)cosQ

Continue simplifying down:

-435 = -720cosQ

Divide both sides by '-720':

0.604 = cosQ

cos^{-1}Q = 0.604

m∠Q ≈ 52.83 or 53° rounded to the nearest whole degree.
