Answer is F
Step-by-step explanation:
Answer: 21120 feet.
Step-by-step explanation: We start with the fraction 1/180, found by putting 20 seconds over one hour. Then, we need to get the amount of miles the speed of sound travels in 20 seconds. We can use the fraction above as a ratio to get it. 720/1 x 1/180 = 4 miles. Then, we'll just do 4 times 5280, which is 21120.
Since we know 16 ounces equal a pound, we just need to divide 72 by 16.
72/16 = 4.5
Your answer should be 4.5 pounds. Hope this helps!
The given 8 rolls will have a length of 144 feet or in other words, they will be 144 feet long.
Here, we are given that thee are 8 rolls of carpet and each roll is 6 yards long.
We know that the conversion factor of yards to feet is as follows-
1 yard = 3 feet
Thus, 6 yards = (6 × 3) feet
= 18 feet
⇒ each roll of carpet is 18 feet long
Since there are a total of 8 carpets given, the length of all the 8 rolls will be given as follows-
18 × 8
= 144
Thus, we find that the given 8 rolls will have a length of 144 feet or they will be 144 feet long.
