An art museum received a collection of 92 African American paintings. The museum can display 40 of the paintings on the first floor. Explain how you could find the percent of paintings displayed on the first floor.

About 43% of the paintings are displayed on the first floor.

Step-by-step explanation: For this problem we can use a percent equation to solve for p, the percent of paintings that will be displayed on the first floor.

Lets write the percent equation:

40/92 = p/100  (We basically are finding 40 out of 92 paintings is what percent of the total paintings.

40/92 x 100 = p/100 x 100 (We always multiply both sides by 100 when dealing with percent that are out of a whole, or 100.)

40 x 100 = 4000/92 = ABOUT 43. p/100 x 100 = p.

About 43 = p

So about 43% of the paintings are displayed on the first floor.

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
