Question

Questions below!! :D

Answer 1

Find the consecutive whole numbers that each number falls between. Then estimate the numbers value.

Answer 2

\[\sqrt{55}\]

Answer 3

\[\sqrt{8}\]

Answer 4

55 falls between 49 and 64, and \(\sqrt{49}=7\) and \(\sqrt{64}=8\). So, you know that \(\sqrt{55}\) falls somewhere between these two.

Try using the same reasoning to estimate \(\sqrt8\).

Answer 5

Okay hold on

Answer 6

Wait but i thought that you took \[\sqrt{55}\] which is 7.4 rounds to 8 which is between 7 and 9? is it like that?

Answer 7

You're supposed to estimate based on the fact that \(\sqrt{49}<\sqrt{55}<\sqrt{64}\), or \(7<\sqrt{55}<8\).

7 and 8 are the "consecutive whole numbers" you have to find first. Then you make a guess like 7.4 or 7.5.

Answer 8

So for \[\sqrt{55}\] its 7 and 8 and the whole value or whatever is 7.4

Answer 9

Right?

Answer 10

The *estimated* value is 7.4, yeah.

Answer 11

ok so for 8...

Answer 12

Find the two consecutive perfect squares that 8 falls between, then...

Just like the first one.

Answer 13

estimated 2.8 then 3 and 4?

Answer 14

It looks like you did it backwards.

First, you notice that \(4<8<9\). 4 and 9 are perfect squares, and so you know that \(\sqrt4<\sqrt8<\sqrt9\), or that \(2<\sqrt8<3\). Then you make the guess of 2.8.

Answer 15

okay so 2.8 is right.. so what about the 3 and 4 for the consectutive numbers

Answer 16

Are they right?

Answer 17

They are.

Answer 18

ok

Answer 19

so for 55 7 and 8 for consectutive and 7.4 for estimate?
