Answer:
eliver mail. The table shows the truck's distance d from the post office at time t. Calculate the average rate of change over the interval from 8 to 15 minutes. t(min) d (km) 0 0 8 7 11 11 15 14 22 16 (1 point) The rate of change is about 0.8 kilometers per minute. The rate of change is 7 kilometers
Step-by-step explanation:
1)Take the time he is traveling divided by the speed to get the time.
2)Subract the time you have got from the average time,then subtract the average distance from the traveling distance,then divide the two to get the speed.
3)Take the total distance, divide it by the total time to get the average speed.
Price after off =80- 1/4 * 80 = 80-20 = $60
Coupon discount = 60*10/100 = $6
So, he have to pay, 60-6 = $54
Answer:
0.012t + 28 = 30
Step-by-step explanation:
The depth starts at 28 meters. The amount of increase in t minutes will be 0.012t, so the total depth after t minutes is ...
0.012t +28
We want to find when that is equal to 30, so the appropriate equation is ...
0.012t +28 = 30
0.7 / 100 = 0.007 or 0.007 x 100 = 0.7 hope this helps
