Answer:
The answer is below
Explanation:
The question is not complete, the complete question is in the form of: David is choosing between two exercise routines. In Routine #1, he burns 20 calories walking. He then runs at a rate that burns 10.5 calories per minute. In Routine #2, he burns calories 38 walking. He then runs at a rate that burns 8.5 calories per minute. For what amounts of time spent running will Routine #1 burn at most as many calories as Routine #2? Use for the number of minutes spent running, and solve your inequality for .
Answer:
Let us assume that the number of minutes spent running is t minute. The equation that represents the total calories burnt for routine 1 is given as:
20 + 10.5t
While the total calories burnt for routine 2 is given as:
38 + 8.5t
Since Routine #1 burn at most as many calories as Routine #2, hence it can be represented by the inequality
20 + 10.5t < 38 + 8.5t
Solving the inequality:
10.5t - 8.5t < 38 - 20
2t < 18
t < 9 minutes
For routine 1 to burn at most as many calories as routine 2, the time spent running must be less than 9 minutes
Disappears with no ill effects

Answer:
Option D is correct.
Explanation:
To measure and compare the muscular endurance of two persons with completely different physical features, the best method is the Fixed percentage method.
With this method, first, you determine the 1 RM (one repetition max) or the maximum weight this person can lift in a full repetition. Then you use 70% of that weight to calculate the muscular endurance.
If someone's RM is 200 lb, then you will use 140 lb (70% of 1 RM) to conduct the test.
This method takes into account the person's specific capabilities, as the 70% of a 140 lb person will be completely different from the one of a 210 lb person.
