The number of cars at a dealership dropped from 64 to 48 after a weekend sale.

what is the percent decrease in the number of cars?

round to the nearest percent, if necessary.

20%

25%

30%

75%

25%

Step-by-step explanation:

{(whole- part)/whole}*100%

(64 -48)/64 *100%= 25%

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
