We know that
area of the square=b²-------> b=√area
where
b is the side length of the square
for the smaller square
area=256 m²
b=√256-------> b=16 m
for the larger square
area=625 m²
b=√625-----> b=25 m
<span>the ratio of their sides is 16/25</span>
x=8
Explanation:
the opposite side is 72, which means I have to make 9x end up equaling 72.
72÷9
////
72/9
=8
9×8=72
<u>Therefore</u>
the value of x is 8.
Start by proving to them that the number 0.57 can be converted into a fraction . A whole number can't exactly be put in to a fraction. 0.57 can be converted to 14.25/25. This information means that 0.57 IS a rational number. Hope this convinced them!
There are 15 articles of clothing
5 are blue and 10 are red
5/15 will give you a percent which is your answer
Answer 0.333333333
A/2-b/3=1 solve for a, add b/3 to both sides
a/2=1+b/3 which is equal to
a/2=(3+b)/3 multiply both sides by 2
a=(6+2b)/3 now you can substitute this into 2a+3b giving you:
2(6+2b)/3 + 3b which is equal to
(12+4b+9b)/3
(13b+12)/3
