4 is 80% of what number?

2 answers:

6 0

Your equation would be 4=80%x. Let X represent the number you are looking for.
First, you must change 80% in to a decimal because you cannot multiply a percent. 4=8x
Then, divide 4 by 8 to solve X.
Your answer is .5.
To check if your answer is correct, plug in .5 into the equation. 4=8×.5.

A circle has a diameter of 12 units, and its center lies on the x-axis. what could be the equation of the circle? check all that

The equation of a circle with radius of 6 units and center on the x axis could be (x - 6)² + y² = 36

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

The circle has a diameter of 12 units. Hence, radius = 12/2 = 6 units.

The center of the circle is at x axis (*, 0), the equation could be:

(x - 6)² + (y - 0)² = 6²

(x - 6)² + y² = 36

The equation of a circle with radius of 6 units and center on the x axis could be (x - 6)² + y² = 36

The population of Detroit, Michigan, decreased from 1,027,974 in 1990 to 688,701 in 2013 (Source: U.S. Census Bureau). Find the

AleksandrR [38]

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

to get the slope of any straight line, we simply need two points off of it, so let's use the ones provided in that

$\begin{array}{|cc|ll} \cline{1-2} \stackrel{years}{x}&\stackrel{population}{y}\\ \cline{1-2} 1990&1027974\\ 2013&688701\\ \cline{1-2} \end{array}\hspace{5em} (\stackrel{x_1}{1990}~,~\stackrel{y_1}{1027974})\qquad (\stackrel{x_2}{2013}~,~\stackrel{y_2}{688701}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{688701}-\stackrel{y1}{1027974}}}{\underset{run} {\underset{x_2}{2013}-\underset{x_1}{1990}}} \implies \cfrac{-339273}{23}\implies -14751\qquad \stackrel{rate~of}{change}$

let's notice, is negative since the population decreased.

jenyasd209 [6]

Answer:

Step-by-step explanation:

We can write a proportion to solve

5 made x made

------------ = -----------

3 missed 36 missed

Using cross products

5 * 36 = 3x

Divide each side by 3

5 * 36/3 = 3x/3

50 = x

She made 60
