The constant of proportionality should be 45 miles per hour, and the car should travel 135 miles in three hours.
Exterior angles for n sides = 360/n = 17.14, n = 360/17.14 = <span>21 sides</span>
For us to find out how many times more expensive is the deli roast compared to the uncooked roast we need to change the units;
cost of 100g=0.221lb is $2.99
cost of 1 lb will therefore be:
1/0.221*2.99
=$13.53/lb
therefore the number of times more expensive the deli roast is compared to uncooked roast is:
[price of 1lb roasted meat]/[price of 1 lb uncooked meat]
=13.53/4.99
=2.7 times
