Answer:
10 calories per minute
Step-by-step explanation:
We do not have much information to go on such as the speed that Tai is biking or his/her weight. Regardless we can use the data gathered by the University of Harvard which after a study came up with the following results. Their results showed that if an individual bikes at a speed of 13 mph and are around 155 pounds they will burn calories at a rate of 10 calories per minute. Therefore we can assume that Tai is burning roughly 10 calories per minute. This rate increases if the person bikes at a faster speed or weighs more as they are exerting more energy.
A kite is a four-sided polygon with two sets of equal side. If we let x be the length of the first two sides, we represent the length of the second set as 2x-5. Given the perimeter,
P = 2L + 2W
8 = 2(x) + 2(2x - 5)
The value of x is 3. Thus, the sides of the kite measure 3 cm, 3 cm, 1 cm, and 1 cm.
