Arte-miy333 [17]

Answer:

The correct answer would be - remain the same.

Explanation:

In the given table showing the average daily calories requirement according to the weight of the adult men. Which is as follows:

weight                daily intake

132                        2250

154                        2450

176                        2650

198                        2850

220                       3050

242                       3250

In this, the highlight weight and required calories should be taken by the man who does not perform any physical exercise but according to the question a man with 154 lb perform a moderate exercise, and according to the CDC a 154 lb men can burn anywhere between 140 and 295 calories in 30 minutes by moderate exercise for an hour.

Thus, the total calories he takes: 2700

burn by exercise: 295

should take: 2450

then = 2700 - (2450+295)

= 50 calories over the limit that will have negligible effect on the weight.
