How do you determine whether you are finding a percent of increase or a percent of decrease between two values? Explain.

Slav-nsk [51]

Answer:

Increase:

It will have increase when y>x

so, percentage of increase is

$=\frac{y-x}{x}\times 100$

Decrease:

It will have decrease when x>y

so, percentage of decrease is

$=\frac{x-y}{x}\times 100$

Step-by-step explanation:

Let's assume initial value as x

assume final value as y

Increase:

It will have increase when y>x

so, percentage of increase is

$=\frac{y-x}{x}\times 100$

For example:

Initial value is 40

So, x=40

Final value is 50

so, y=50

now, we can find percentage in increase

$=\frac{50-40}{40}\times 100$

$=25$

Decrease:

It will have decrease when x>y

so, percentage of decrease is

$=\frac{x-y}{x}\times 100$

For example:

Initial value is 50

So, x=50

Final value is 40

so, y=40

now, we can find percentage in decrease

$=\frac{50-40}{40}\times 100$

$=25$

Using rounding to estimate the solution to the problem. 538-714 Be sure to give the estimated solution, not the exact solution.

amid [387]

Answer:

1. -370

2. 70

3. 10.75

4. 6700

5. 37.26

Step-by-step explanation:

1. Estimating the solution means round the numbers to the nearest ten, then subtract the rounded numbers.

2. Same thing as #1

3. Using long division, it should be quite easy. If you need more evaluation, comment and I'll answer.

4. To the nearest hundred, you write the closest exact hundred. example: 8334 would be rounded to 8300.

5. To the nearest hundredth, you write the closest exact hundredth. example: 65.734 would be rounded to 65.73

Hope this helped, good luck!

This quarter circle has a radius of 7 centimeters what is the area of this shape?

IgorLugansk [536]

Answer:

153.94

Step-by-step explanation:

I literally just typed in "how to find area of a circle with given radius" to refresh my memory lol. But then all I had to do was type in the radius and it gave me the answer: 153.94

However, if you need the actual steps:

Use the formula: A = πr^2

A = π7^2

A = 49π

A = 153.938 which rounds to 153.94 :)
