To round to the nearest ten, we will look at the number in the ones place, and determine if it is higher, lower, or equal to 5. In this case, 3 is less than 5, so we round down. This means that 483 rounded to the nearest ten is 480. :) I hope this helps you in the future! A common phrase you can think about is:
Four or less, give it a rest. 5 and above, give it a shove.
So first we need to convert all of these to feet:
2450 yards is 7350 feet
3 miles is 15840 feet
Now we need to find the perimeter and then multiply by 2:
2(7350) + 2(15840) = 43680
2(43680) = 87360
Answer:
13405
Step-by-step explanation:
because 35 x 383 = 13405 so yes
