$3.29 for 9.25 ounces

How much is it per ounce?

About $0.36 per ounce

Step-by-step explanation:

Set up a proportion.

Let p = price per ounce

3.29/p = 9.25 ounces/(1 ounce)

9.25p = 3.29

p = 3.29 ÷ 9.25

p = 0.3556756757

We can say 35 cents per ounce or 36 cents per ounce if rounded to 2 decimal places.

angle addition postulate

2x=56

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."
