Answer:
false 1 is equal to its own square
Answer:
(D). 6.
Step-by-step explanation:
The number of parts = 1 + 10 = 11.
So 10/11 of the alloy is copper and 1/11 is aluminium.
So the answer is 1/11 * 66
= 66/11= 6 pound,s
Answer:
X ∈ {-2, -1 ,1 ,5 ,6}
Step-by-step explanation:
<h2 />
<span>The side length of square AA is 1212 yards.
The ratios of side length between AA and BB is 4:9.
To determine the side length of BB, we need to compare the ratios:
(4/9)=(1212/x) where x is the side length of BB.
If you solve for x, then you have: x= (1212)*(9/4) = 2727 yards
A square has 4 equal sides so once you have the side length, you can solve for the perimeter, which is the total length of all the sides.
Perimeter = 4 * 2727 = 10,908 yards.</span>
