The number of square feet of carpet you need to buy is; 203 ft²
Total Cost of Carpet = $281.51
<h3>How to solve algebra word problems?</h3>
We are given;
Measurement dimensions = 11.75 ft by 17.25 ft
A) The number of square feet would be needed is the area of the carpet. Thus;
Number of Square foot = 11.75 * 17.25
Number of Square foot = 202.6875 ft² ≈ 203 ft²
b) From conversions, we know that;
1 sq. feet = 1/9 sq. yards
Thus;
203 sq.ft = 203 * 1/9 sq.yards = 22.56 sq. yards
Now, the cost of carpet is $11.49/sq yd and the sales tax is
do 8.6%. Thus;
Total Cost of Carpet = (11.49 * 22.56) + 8.6%(11.49 * 22.56)
Total Cost of Carpet = $281.51

<h3>
Answer: 6 hours, 40 minutes</h3>
======================================================
Work Shown:
(x hours strength)/(4 hours endurance) = 5/3
x/4 = 5/3
3x = 4*5
3x = 20
x = 20/3
x = (18+2)/3
x = 18/3 + 2/3
x = 6 + 2/3
x = 6 & 2/3
He needs to spend 6 full hours, plus an additional 2/3 of an hour, on strength training.
1 hr = 60 min
2/3 hr = (2/3)*60 min
2/3 hr = 40 min
6 hr + 2/3 hr = 6 hr + 40 min
Therefore, he needs to spend 6 hours, 40 minutes on strength training.
This is equivalent to 6*60+40 = 360+40 = 400 minutes.
