There are 20 pieces of fruit in a bowl and 5 of them are apples. What percentage of the pieces of fruit in the bowl are apples?

25%

Step-by-step explanation:

In order to find percentage, we can write this relationship as a fraction, with the larger number in the denominator.

This fraction simplifies to

If we divide, we get 0.25. Therefore, the answer is 25%

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
