Answer:Marvin burned more calories per hour.
Step-by-step explanation:
Thomas went for a long hike and burned 657 calories in 2 1/2 hours. Converting 2 1/2 hours to improper fraction, it becomes 5/2 hours
This means that the amount of calories that Thomas burnt in 1 hour would be 657 × 2/5 = 262.8 calories per hour
Marvin decided to go for a bike ride and burned 1,035 calories in 3 1/4 hours. Converting 3 1/4 hours to improper fraction, it becomes 13/4 hours
This means that the amount of calories that Thomas burnt in 1 hour would be 1035 × 13/4 = 3363.75 calories per hour
Therefore, Marvin burns more calories per hour.

so, for this one you first figure out how many study French.
2/9 of 270 is 60 (simple method: 1/9 is 270 divided by 9, which is 30. So 2/9 is 1/9 multiplied by 2, which is 60).
60 are doing French.
Then use this in the ratio of French to Spanish (3:7) and you have 3 and 60 on the same side. You have to multiply 3 by 20 to get to 60 (or divide 60 by 20 to get 3).
So the number you use to do the same to the other side of the ratio is 20.
7 multiplied by 20 (or 7 multiplied by 10, then multiply that by 2) to get 140.
140 are doing Spanish.
Then take the French and Spanish from the big total and you get 270-140-60=70
70 are doing German.
Of these 70, 42 are boys. 70-42 gives 28 girls. 42/70 is the fraction of boys doing German. This is the same as 6/10 and to get a percentage you multiply the fraction by 10 so that the bottom of it is out of 100 (so that’s 60/100).
And 60/100 is the same as 60%.
So your answer is 60%

A rational number includes any whole number, fraction, or decimal that ends or repeats. An irrational number is any number that cannot be turned into a fraction, so any number that does not fit the definition of a rational number.
Alex is correct the book would cost $18.52 before taxes adding 10% tax the book would cost an additional $1.85 for a total of $20.37. This would be just under the $21.00 that both Alex and Laura had to spend. Laura tried to combined the 35% discount which you cannot do. So yes they both would be able to purchase the book.
5,486 plus 8,602 is equal to around 14,000, give or take.
