The perimeter is the sum of all lengths of the side of a polygon. For a triangle it is expressed as:

P = a + b + c

We let a = 7.3, b = 2.94 and c=x

Therefore, the perimeter of the given triangle is:

14.8 = 7.3 + 2.94 + x

From the options given, the correct answer is the last option. The expression, <span>x - 14.8 = 2.94 + 7.3, will give an erroneous value of the third side. It will be more than the perimeter given.</span>

Assume that riding a bike burns 50 calories per mile. If you ride at a speed of 15 miles per hour, what is your average power ou

beks73 [17]

50 calories are consumed per milefor 15 miles per hour, calories consumed
= 50*15
=750 calories per hour,
this is equal to 750/3600
= 0.2083 calories/second, given that,
1 calorie per sec
= 4.19 watt, the average power output
= 0.2083*4.19
= 0.873 Watts
