6) Kate wants to buy some daisies for $6.99, some potting soil for $3.98, and a ceramic pot for $7.95. She has $20.00. Which num

Mama L [17]

By taking a subtraction, we will see that the change that Kate receives is $1.08

<h3></h3><h3>How to get the change?</h3>

The change will be given by the difference between what Kate has, and the cost of all the items she buys.

She has $20.00, and the costs are: $6.99, $3.98, and $7.95.

Then the change will be:

C = $20.00 - $6.99 - $3.98 - $7.95 = $1.08

We conclude that the change is $1.08

I need help thank you

Answer:

≈ 5

Step-by-step explanation:

<u><em>You can use the Pythagorean Theorem to solve this:</em></u>

$a^{2} + b^{2} = c^{2}$

<u><em>Now plug in the numbers into the formula:</em></u>

$6^{2} + b^{2} = 8^{2}$

36 + $b^{2}$ = 64

<u><em>Subtract 36 from both sides:</em></u>

36 + $b^{2}$ = 64

-36 -36

_________

$b^{2}$ = 28

<em><u>Square both sides:</u></em>

$\sqrt{b^2} = \sqrt{28}$

b = 5.29

b ≈ 5
