What is the percent of change from 800,000 to 600,000?

Dimas [21]

$\frac{1}{2} s$ = 4s - 21

First, simplify $\frac{1}{2} s$ to $\frac{s}{2}$ / Your problem should look like: $\frac{s}{2} = 4s - 21$
Second, multiply both sides by 2. / Your problem should look like: $s = 8s - 42$
Third, subtract 8s from both sides. / Your problem should look like: $s - 8s = -42$
Fourth, simplify s - 8s to -7s. / Your problem should look like: $-7s = -42$
Fifth, divide both sides by -7. / Your problem should look like: $s = \frac{-42}{-7}$
Sixth, simplify $\frac{42}{-7}$ to $- \frac{42}{7}$ / Your problem should look like: $s = \frac{42}{7}$
Seventh, simplify $\frac{42}{7}$ to 6. / Your problem should look like: $s = 6$

Answer: s = 6

The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 36 m, Find t

Korvikt [17]

Applying the Pythagorean theorem, the height of the building is: 24.9 m.

<h3>How to Apply the Pythagorean Theorem?</h3>

Where c is the length of the hypothenuse of a right triangle, and a and b are the legs of the right triangle, the Pythagorean theorem states that:

c = √(a² + b²).

The diagram of the building and its shadow form a right triangle as shown in the image below, where:

a = height of the building

b = 26

c = 36

Applying the Pythagorean theorem, we will have:

a = √(36² - 26²)

a = 24.9 m
