Answer:
$0.20
Step-by-step explanation:
To find the price of the apples we will divide the total price buy the number of apples. 1.8/9
1.8/9=.20
So each apple cost $0.20
Time to check
.20 x 9=1.8
2 inches per minute. Just divide the total amount of inchs by the number of minutes and you have your unit rate.
2(5x-15) + 2(2x+7) =0
10x-30+4x+14 = 0
14x = 16
x = 8/7
Answer:
240 m
Step-by-step explanation:
Figure is attached.
The distance the particle travels is the area under the v-t graph over the time interval from 0 min to 4 min. The reason you can't just multiply velocity by time is that the velocity is changing at a constant rate over the given time interval (the line is going upward--the particls is speeding up).
What's the area under the graph?
The red outline forms a trapezoid. The area of a trapezoid is where the <em>b</em>'s are the lengths of the two parallel base and <em>h</em> is the height (the distance between the bases).
Reading the graph carefully (notice the scales!)...
