If the average (arithmetic mean) of 2, 7, and x is 12, what is the value of x?

stealth61 [152]

Answer:

x = 27

Step-by-step explanation:

mean is calculated as

mean = $\frac{sum}{count}$

sum = 2 + 7 + x = 9 + x and count = 3 , then

$\frac{9+x}{3}$ = 12 ( multiply both sides by 3 to clear the fraction )

9 + x = 36 ( subtract 9 from both sides )

x = 27

Find the area of the triangle given below.

Nimfa-mama [501]

Given:

A triangle with a base length of 22 ft and a height of 20 ft.

To find:

The area of the given triangle.

Solution:

The area of a triangle is obtained by multiplying $\frac{1}{2}$ with its base length and its height.

The area of a triangle $= \frac{1}{2} (b)(h).$

The height is the distance from the base to the highest point on the triangle and the length of the base is the base length.

The given triangle has a base length of 22 ft and a height of 20 ft.

The area of the triangle $= \frac{1}{2} (b)(h) = \frac{1}{2} (22)(20).$

$\frac{1}{2} (22)(20) = \frac{1}{2} (440) = 220$ ft².

The given triangle has an area of 220 ft².
