Answer:

There are 21 emperor penguins at the zoo

Step-by-step explanation:

The total number of penguins in the zoo = 60

The percentage share of emperor penguin in the total population of penguin = 35 %

Number of emperor penguins at the zoo

\frac{35}{100} * 60

0.35 * 60

= 21

There are 21 emperor penguins at the zoo

The length of a rectangle is five times its width.
Vera_Pavlovna [14]

Answer:

72

Step-by-step explanation:

l = 5w

A = l*w

180 = 5w *w

180 = 5w^2

Divide each side by 5

180/5 = 5w^2 /5

36 = w^2

Taking the square root of each side

sqrt(36) = sqrt(w)^2

6 =w

l = 5w = 5*6 = 30

The perimeter is

P = 2(l+w)

P = 2(6+30) = 2(36) = 72
