What is the surface area of the figure 8" 8" 12"

fgiga [73]

First, find the surface area of the bigger sides (there are 4 of them so what you get for one you will multiply by 4)

12 x 8 = 96

96 x 4 = 384

Then find the surface area of the smaller sides ( there are two small sides so multiply your answer by two)

8 x 8 = 64

64 x 2 =128

Then add both together

128 +384 = 512

Hope this helps :)

An ecologist studies the fox population of the arctic circle, and observes that the population loses 1/11 of its size every 7 mo

Ksju [112]

Answer: The fox population decrease 1.298% every month.

Step-by-step explanation:

Since we have given that

Initial foxes = 170000

Every 7 months, the population loses $\dfrac{1}{11}$

So, we need to find the rate of change in population every month.

So, we will use "Unitary method":

So, In every month, the population loses $\dfrac{1}{11}\times \dfrac{1}{7}=\dfrac{1}{77}$

So, the percentage would be

$\dfrac{1}{77}\times 100=1.298\%$

Hence, the fox population decrease 1.298% every month.
