Answer:
A, B, C, E, D
F, G, H, I, J
Step-by-step explanation:
You can go at this a couple of ways.
Consider the squares of number 1 through 9.
![\begin{array}{cccccccccc}n&1&2&3&4&5&6&7&8&9\\n^2&1&4&9&16&25&36&49&64&81\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcccccccccc%7Dn%261%262%263%264%265%266%267%268%269%5C%5Cn%5E2%261%264%269%2616%2625%2636%2649%2664%2681%5Cend%7Barray%7D)
Then when the number under the radical is close to n², the root on the number line will be close to n.
The other way you can do this is to find the square root using your calculator.
- √10 ≈ 3.2 ⇒ A
- √35 ≈ 5.9 ⇒ B
- √48 ≈ 6.9 ⇒ C
- √71 ≈ 8.4 ⇒ E
- √54 ≈ 7.3 ⇒ D
- √19 ≈ 4.4 ⇒ F
- √89 ≈ 9.4 ⇒ G
- √6 ≈ 2.4 ⇒ H
- -√20 ≈ -4.5 ⇒ I
- -√2 ≈ -1.4 ⇒ J
10 + 10 + 10 + 5 + 5 = 40. 40/5 = 8 pieces on average.
Jack's age is 14, so his age can't be 14 - g
Mara's age is 14 - g, which means she is g years young than Jack(not older because if she was older, you would need to add not subract)
The answer is B.
Answer:
13
Step-by-step explanation:
First find the average the numbers (40 / 4 = 10)
2 are more and 2 are less
