Remark

One of the things you need to do is learn to read phrase by phrase.

What is the quotient of a number and 7? That meas you have a number, x, and it is divided by 7. What you do that the answer you get is the quotient.

x/7 is what you know so for. Now the first part says you take 12 away from that.

x/7 - 12 is what you have after doing that.

The result you get is - 2

x/7 - 12 = - 2 Add 12 to both sides

x/7 - 12 + 12 = - 2 + 12

x/7 = 10 Now multiply by 7

x = 10 *7

x = 70 <<< Answer the number is 70

4. Mr. Perez's science students conducted a wildlife count in the local forest. The results of their count are shown in the tabl

Circle graphs are used to display the relationship between variables using a complete circle

The angle measures of the sections are 180 degrees, 72 degrees, 72 degrees and 36 degrees, respectively.

The count of the animals are given as:

Squirrel = 25
Rabbit = 10
Deer = 10
Raccoon = 5

The total count of animals is:

$\mathbf{Total = 25 + 10 +10 + 5}$

$\mathbf{Total = 50}$

The angle measure of each section is then calculated using:

$\mathbf{Angle = \frac{Animal \times 360}{Total}}$

So, we have:

$\mathbf{Squirrel = \frac{25 \times 360}{50} }$

Simplify the numerator

$\mathbf{Squirrel = \frac{9000}{50} }$

Divide

$\mathbf{Squirrel = 180}$

$\mathbf{Rabbit= \frac{10\times 360}{50} }$

Simplify the numerator

$\mathbf{Rabbit= \frac{3600}{50} }$

Divide

$\mathbf{Rabbit= 72}$

$\mathbf{Deer= \frac{10\times 360}{50} }$

Simplify the numerator

$\mathbf{Deer= \frac{3600}{50} }$

Divide

$\mathbf{Deer= 72}$

Lastly, we have:

$\mathbf{Raccoon= \frac{5\times 360}{50} }$

Simplify the numerator

$\mathbf{Raccoon= \frac{1800}{50} }$

Divide

$\mathbf{Raccoon= 36}$

Hence, the angle measures of the sections are 180 degrees, 72 degrees, 72 degrees and 36 degrees, respectively.
