a hose fills a hot tub at a rate of 3.14 gallons per minute. How many hours will it take to fill a 329 gallon tub?

1 answer:

5 0

There are 60 minutes in an hour, so to find the hourly rate, you would multiply 3.14 by 60, which gives us 188.4. If the rate is 188.4 gallons an hour, then we can divide 329 by 188.4. The full number would be 1.7462845011, but you can simplify that. If you need the minimum number of precise hours needed, then it would be 2. If you are allowed a small amount of error through simplifying your decimals, then you could say about 1.7.

Find the given angle measure for regular hexagon ABCDEF.

stepan [7]

Answer:

Question 12: 60°

Question 13: 30°

Question 14: 60°

Question 15: 120°

Step-by-step explanation:

Question 12: The measure of a circle is 360°, so ∠CGD which is $\frac{1}{6}$ of a full rotation is 60°.

Question 13: ∠CGH is $\frac{1}{2}$ of ∠CGD, so its angle measure is 30°.

Question 14: Since the interior sum of all angles in a triangle is 180° and two angles have measures of 90° and 30°, that means ∠HCG has a measure of 60°.

Question 15: Since ∠EGC is $\frac{1}{3}$ of a full rotation, and is twice as great as ∠CGD, that means it has an angle measure of 120°.
