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

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

$=25$

Help please The area of the figure is blank square units

zimovet [89]

Answer:

132 square units

Step-by-step explanation:

First, I would figure out the areas of the right triangles

Left triangle: 1/2(6x8) =24 units²

Right triangle: 1/2(8x3) = 12 units²

entire rectangle between triangles: 12x8 = 96 units²

add all areas together: 24+12+96 = 132 units²
