My textbook doesn't explain square roots well. Can someone help me understand? Example 1 is the square root of 9

Vilka [71]

A square root is doing the opposite of squaring. Squaring is multiplying a number by itself. Square rooting is trying to figure out what number squares into the number you have currently.
For your Example 1, the square root of 9 is 3.
3 x 3 = 9.
Some better examples are:
4 x 4 = 16.
4 is the square root of 16, and 16 is the square of 4.

Kaitlyn is making a quilt she purchased a 46 foot long piece of lace to sew around the edges of the quilt she needs 322 inches o

kupik [55]

Answer:

<u>19.17 feet</u> of lace will be leftover.

Step-by-step explanation:

Given:

Kaitlyn is making a quilt she purchased a 46 feet long piece of lace to sew around the edges of the quilt she needs 322 inches of lace for the quilt.

Now, to find the feet of lace will be leftover.

<u><em>Total feet of lace =</em></u> <u>46</u>.

Kaitlyn needs lace for the quilt = 322 inches.

So, by using conversion factor we change inches into feet:

12 inches = 1 foot.

322 inches = $\frac{322}{12} =26.83\ feet.$

<u><em>Feet of lace she need for the quilt =</em></u> <u>26.83</u>.

Now, to get the feet of leftover lace:

<u><em>Total feet of lace - feet of lace she need for the quilt</em></u>

$=46-26.83$

$=19.17\ feet.$

Therefore, 19.17 feet of lace will be leftover.
