Mr. Ryan had 8 yards of cable. He used 12 ft. 6 in. to hook up the television in his living rooom. Then he used 10 ft. 2 in. to hook up the television in his office. How many feet of cable did Mr. Ryan have left?

Is the answer 27

8 yards is 24 feet, right?

He used
10'2"
+12'6"
or
22' 8" total used.
So how much is left?

1 ft. 4 inches?

exactly correct. Go to the head of the class.

To find out how many feet of cable Mr. Ryan had left, we need to subtract the total length of cable he used from the initial length of cable he had.

First, we need to convert the length of cable used in feet and inches to just inches.

12 ft. 6 in. is equal to (12 * 12) + 6 = 150 inches.
10 ft. 2 in. is equal to (10 * 12) + 2 = 122 inches.

Now, let's calculate the total length of cable used:
150 inches + 122 inches = 272 inches.

Since there are 36 inches in a yard, we can convert the answer to yards:
272 inches / 36 inches = 7.5555 yards (rounded to four decimal places).

To find out how many feet of cable Mr. Ryan had left, we subtract the total length used from the initial length of 8 yards:
8 yards - 7.5555 yards = 0.4445 yards.

Finally, we convert the remaining yards to feet:
0.4445 yards * 3 feet = 1.3335 feet.

Therefore, Mr. Ryan had approximately 1.3335 feet of cable left.
