Answer:
1000 miles
Step-by-step explanation:
Given the following :
Number of miles driven :
First trip = 240 miles
Second day = 205 miles
Third day = 315 miles
Fourth day; miles driven before arriving at their final destination = 220 miles
Total number of miles driven after 4 days before reaching their destination :
(240 + 205 + 315 + 220) = 980 miles
However, they still haven't reached their destination ;
Using front end estimation :
We can take the total miles recorded and make an estimation based on the first digit of the recorded miles traveled:
In other to estimate 980 using front end estimation : the actual number is replaced with a number with only one nonzero digit (which is the first digit)
Hence,
980 - - - - > we round the digit after 9 either 1 or 0, since it is greater than 4, then it is rounded to and added to the first digit, all subsequent dots are rounded to zero
Hence 980 - - - - > 1000
Hence, estimated miles driven = 1000 miles
Answer:
The answer is D. Range Hopefully this helps!
No it does not it would have to be a straight line
Answer: 15
Step-by-step explanation: Perimeter is adding the width and the length together. For a rectangle, it has four sides, so it has two lengths and two widths. The width is 10, so you add 10 + 10 which is 20. The length of the rectangle would be 15 since 15 + 15 is 30, and then 30 + 20 = 50, the perimeter.
