Answer:
250 miles
Step-by-step explanation:
So we know that the time (t) equals 5 hours and that the rate (r) equals 50 mph. So knowing that, we can use the formula t*r=distance. We plug in the numbers and we get 250 miles.
Another way to think about this is, since we go 5 hours and 50 miles per hour, every hour we go 50 miles and we do that for 5 hours, so we go 50, 100, 150, 200, 250.
Let the width be x
width = x
length = 2x - 3
Perimeter = x + 2x - 3 + x + 2x - 3 = 6x - 6
6x - 6 = 78
6x = 78 + 6
6x = 84
x = 14 cm
2x - 3 = 2(14) - 3 = 25cm
The width is 14cm and the length is 25cm
Answer:
Each Pencil Cost 4 Dollars
Step-by-step explanation:
First you can subtract 21 by 9 to get 12 dollars which shows how much he spent.
Second you can divide 12 by 3 to get 4 dollars spent. So he spent 4 dollars on each pencil.

Answer: Mean= 82.8
Median= 95
Mode=100
Step-by-step explanation:
Mean is the average of the scores
Mean= 95+100+65+95+75+98+100+55+100+45 =828/10= 82.8
To get the median, we rearrange the numbers in either ascending or descending order.
45,55,65,75,95,95,98,100,100,100
Median= 95
Mode is the number that occurs most which is 100
