To find out how much of the weight is muscle, we need to determine the ratio of muscle weight to body weight for the certain animal.
According to the given information, there are approximately 4lbs of muscle for every 5lbs of body weight. This can be written as:
4lbs muscle : 5lbs body weight
To find out how much muscle weight the 115-lbs animal has, we can set up a proportion using this ratio:
4lbs muscle / 5lbs body weight = x lbs muscle / 115lbs body weight
Cross-multiplying, we get:
4lbs * 115lbs body weight = 5lbs * x lbs muscle
460lbs = 5x
Dividing both sides by 5:
460lbs / 5 = x lbs muscle
x = 92lbs
Therefore, for a 115-lbs animal, approximately 92lbs of its weight is muscle.
To determine the amount of weight that is muscle for a 115-lb animal, we need to first calculate the ratio of muscle weight to body weight.
Given that there are approximately 4 lbs of muscle for every 5 lbs of body weight, we can set up the following equation:
4 lbs of muscle / 5 lbs of body weight = x lbs of muscle / 115 lbs of body weight
To solve for x, we can cross-multiply and then divide:
4 lbs * 115 lbs of body weight = 5 lbs * x lbs of muscle
460 lbs = 5x
Dividing both sides of the equation by 5:
460 lbs / 5 lbs = x
92 lbs = x
Therefore, for a 115-lb animal, approximately 92 lbs of its weight is muscle.
