Which proportion can be used to find 65% of 90? a. 65/90 = x/100 b. 65/x = 90/100 c. 65/100 = x/90 d. x/100 = 90/65

The proportion which represents the 65% of 90 is:

Step-by-step explanation:

Given information:

We need to find the proportion that can be used to find

65% of 90

Let us take :

% of

C.

Step-by-step explanation:

65% means 65 out of 100, or 65/100.

65% of 90 is an unknown number, x.

65 is to 100 as x is to 90.

65/100 = x/90

Answer is C.

tangent

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."
