If ratio of men to women in a city of 54,000 people is 3:1, how many women are there in the city
Ilya [14]

<u>ANSWER</u>

135,000 women are in this city

<u>EXPLANATION</u>

The given ratio of men to women is 3:1

The total ratio is 3+1=4.

The total number of men and women in this city is 54,000.

\frac{ratio \: of \: women}{total \: ratio}  \times total \: population

\frac{1}{4}  \times 54000

= 13500

Therefore the total number of women in this city is 135,000

Find the area of the triangle using Pythagorean theorem
Furkat [3]

Answer:

48

Step-by-step explanation:

Remark

Use a^2 + b^2 = c^2 to solve for the height.

Givens

c = 10

b = 6

h = ?

Solution

b^2 + h^2 = c^2

6^2 + h^2 = 10^2

36 + h^2 = 100            Subtract 36

h^2 = 100 - 36

h^2 = 64                      Take the square root of both sides

sqrt(h^2) = sqrt(64)

h = 8

The height = 8

Area = 1/2 * b * h

Area = 1/2 *12 * 8

Area = 48

Comment

You might wonder where the 12 came from. It wasn't given The base is the whole line across the bottom. 1/2 of it is six. The whole base = 12
