Answer: 300 calories
Step-by-step explanation: let us assume that moving at any speed expends approximately 100 calories per mile. Moving a less-minute mile will burn a few more calories than moving a high-minute mile because of the added effort. Since the minutes for the 3 scenarios are the Same, then we can conclude that he is burning calorie at the same level in which the total equal to 300 calories
Answer:
9 times
Step-by-step explanation:
The best way to go about this is to give actual figures
Let us consider rectangular shape
Let us have a rectangle with dimensions 6 m by 12 m
The area will be 6 * 12 = 72 m^2
The shape having a similar dimension would have dimensions 12m by 36 m
So its area will be ;
18 * 36 = 648 m^2
So we finally proceed to make a division
Mathematically, that will be 648/72 = 9
So the area will be in the ratio of 1 to 9
Answer:
-3
Step-by-step explanation:
-12(x-12)=-9(1+7x)
-12x+144=-9-63x
-12x+63x=-9-144
51x=-153
x=-153/51=-3
Answer:
32.40
Step-by-step explanation:
The shirts were 40% of the regular price
The sale price of 1 shirt was
18*40% = sale price
18*.40 =7.20
He bought 3 shirts, so multiply by 3
3 * 7.2 =21.60
He paid 21.60
The price he would have paid without the discount is
18*3 = 54
The savings is
54- 21.60 =32.40
