Choose the correct simplification of (9xy^5)^2.
Grace [21]

Answer:

D) 81x²y¹⁰

Step-by-step explanation:

(9xy⁵)²

Because all of 9xy⁵ are in the parentheses, each component is raised to the 2nd degree.

(9)² = 81

(x)² = x²

(y⁵)² = y¹⁰ -- When you raise an exponent to another exponent, you multiply the exponents.

Now combine the components.

D) 81x²y¹⁰

A zoo has 151515 Emperor penguins. The Emperor penguins make up 30\%30%30, percent of all the penguins at the zoo.
Fiesta28 [93]

Answer:

50 total penguins

Step-by-step explanation:

In the following example x = the total number of penguins.

Set it up as follows.

15 over x = 30 over 100

Cross multiply the numbers. (30 times x) and (15 times 100)

This results in 30x = 1500.

Divide both sides by 30 which results in x = 50.

This means that there is a total of 50 penguins.

In the following example x = the number of Emperor penguins.

If you would like to double check this, set up as follows.

x over 50 = 30 over 100

Cross multiply the numbers. (30 times 50) (100 times x)

This results in 100x = 1500.

Divide both sides by 100 which results in x =1 5.

This means that there are 15 Emperor penguins.
