Zina [86]

The answer is -30. The absolute value of -3 is 3. Then you evaluate the power of 6 to the power which is 36. Next you multiply the numbers 2 x 3 which is 6. Then calculate the two numbers left over 6 - 36 which is -30.

____ [38]

Answer:

6 3/8 pizzas

Step-by-step explanation:

She estimates that each player will eat three eighths if a pizza and there are 17 players.

Therefore, we have to multiply 3/8 by 17:

3 / 8 * 17 = 6.375 pizzas = 6 3/8 pizzas

They will eat 6 3/8 pizzas.

Answer:

$\large\boxed{C)\ \dfrac{8}{5}\pi\ cm}$

Step-by-step explanation:

The formula of an area of a circle:

$A_O=\pi r^2$

The formula of a perimeter of a circle:

$P_O=2\pi r$

r - radius

We have the area of a circle

$A_O=\dfrac{16}{25}\pi\ cm^2$

Substitute:

$\pi r^2=\dfrac{16}{25}\pi$ <em>divdie both sides by π</em>

$r^2=\dfrac{16}{25}\to r=\sqrt{\dfrac{16}{25}}\\\\r=\dfrac{\sqrt{16}}{\sqrt{25}}\\\\r=\dfrac{4}{5}\ cm$

Calculate the perimeter:

$P_O=2\pi\left(\dfrac{4}{5}\right)=\dfrac{8}{5}\pi$
