First, we can raise each number to the second power by multipying it by itself. :)
1^2=1
4^2=16
9^2=81
16^2=256
These numbers are called "perfect squares" because their square roots are whole numbers, rather than decimals. For example, If you had a square with an area of 16, the side legnths of the square would be the whole (thus "perfect") number 4. For this reason, 16 (4^2) is considered a "perfect square" number. I hope that makes sense!! :)
The first one I'll go with 2nd one ...But I'm dumb so hope that helps
Answer:
u = 7
Step-by-step explanation:
In a parallelogram, GI = GK so:
u + 28 = 5u
4u = 28
u = 7
5:11 is the ratio of those who completed in the freestyle to those who didn't. It <u>would not be 5:16 </u>because 5 of the members from the 16 members did the freestyle. 16-5 equals 11. 5(Men who did freestyle):11(Men who didn't do freestyle)
Your answer is 5:11.
Answer:
-42 ≤ x ≤ 102
