Answer:
319 calories
Step-by-step explanation:
<u><em>Steps to answering this question : </em></u>
- Determine the amount of calories burnt per minute
- Multiply the answer gotten in the above step by 29 minutes to determine the total calories burnt in 29 minutes
Calories burnt per minute = total calories / minutes
220 / 20 = 11 calories
275 / 25 = 11 calories
385 / 35 = 11 calories
11 calories is burnt per minute
Total calories burnt in 29 minutes = calories burnt per minute x 29 minutes
11 x 29 = 319 calories
319
1. The tables represent a ratio of 3:5. For example, 6 x 3 = 18, and 6 x 5 = 30. Also, 20 x 3 = 60, and 20 x 5 = 100.
2. The table has a ratio of 3:4, so the missing blank is 64.
<em>There are 24 pictures</em>
<em>If he drew 1/6 of them ⇒ he drew 1/6 of the 24</em>
1/6 of 24 =1/6 x 24 = 4
So he drew 4 of them.
