The commutative porperty states that numbers can be swapped over , they can change their place in the equation and the result will still be the same.
In our case 13 x 7 x 21, the commutative property means that the numbers can be rearranged
13x7x21=13x21x7=7x21x13=7x13x21

Andre owned a 1/4 acre lot. He wanted to construct a 120’ x 80’ tennis court on the lot. How many square feet will remain uncove
OLga [1]

The area of the tennis court is computed by multiplying the dimensions given,

                               A = 120' x 80'

                               A = 9600 ift


Then, we convert the area in ft² to acres,

                       A = (9600 in²)(2.3 x 10^-5/ 1 in²)

                           A = 0.24 acre


The portion of land remaining is,

                  A of remaining = 0.25 acre - 0.24 acre

                                           = 0.1 acre


The remaining portion is for Andre's studies.


This, 0.1 ft² is equal to the 4% of the given area of the court.

A killer whale can swim 40 miles in 1 1/4 hours. how far can the whale swim in an hour?
bogdanovich [222]
Okay so 1 \frac{1}{4} = 75 minutes. Now we divide 40 by 75. 40÷75=0.53333333333333 miles. We know 1 hour is 60 minutes so we are going to multiply 0.5333333333333 by 60. 60×0.533333333333=32 miles. Therefore, your answer is 32 miles.
