Plz answer its easy math.

Answer:

B and E

Step-by-step explanation:

The rules of indicies states:

$x^{a}$ ÷ $x^{b}$ = $x^{a-b}$

So $3^{-8}$ ÷ $3^{-4}$ = $3^{-8 - - 4}$ = $3^{-4}$

So that means B is one of the correct answers.

To find the other correct value, you can divide the two fractions as stated in the question:

$3^{-8}$ by $3^{-4}$ = $\frac{1}{81}$

81 is equivalent to 3⁴

So that means E is also correct.

Anyone by chance know how to answer this geometry question I need help so bad

NemiM [27]

Answer:

x = -8 and BDC is 68 degrees.

Step-by-step explanation:

Combine -7x+12 and -8x+48 to get -15x+60. Since BDA is a straight angle put the above equation to get -15x+60=180. Subtract 60 from both sides to get -15x=120. Divide -15 both sides to get -8 as your x value. Plug in -8 to BDC, since both negatives are being multiplied, it would turn to a positive number which is 56, add 12 to get 68 as your final result for BDC.

7. The bottom of a circular swimming pool

mote1985 [20]

<h2>Hello!</h2>

The answer is:

1017.88 square feet are blue.

To calculate how many square feet are blue, we need to calculate the area of the bottom of the circular swimming pool.

We need to remember that we can calculate the area of any circle using the following formula:

$Area_{circle}=\pi radius^{2}$
