Step-by-step explanation:
We need to rewrite 36 as product of two square roots of perfect squares.
36 can be written as product of 2 numbers as:
From above we found that only 4 X 9 are square root of perfect squares

For this problem you can create a proportion.
Since 31,100 copies is 7.8% of the total copies spoke up to date you can make this proportion:
31,100. 7.8%
——— =. ———
x. 100%
Now you cross multiply and you will get
7.8x=3,110,000
After this you solve for x by isolating the variable.
7.8x/7.8. 3,110,000/7.8
x=398,717.949
Since the question asks you to round to the nearest whole number which is 7 then the final answer would be 398,718
Answer: There has been 398,718 copies sold to date.
Answer:
Maria bought five shirts and spent a total of $34.25. How much did one shirt cost if all of the shirts cost the same? *We know the price of 5, how do we find the price of 1? ( PLS HELP MEEEEEEE I HAVE MORE WORK TOO
L = the length of the property
W = the width of the property
Area
L * W = 6
but it says," The width of the property is of 3/8 the length he property."
therefore
W = 3%2F8L
or
W = .375L
In the area equation, replace W with .375L
L * .375L = 6
.375L^2 = 6
L^2 = 6%2F.375
L^2 = 16
L = sqrt%2816%29
L = 4 mi is the length
then
.375(4) = 1.5 mi is the width
