Answer:

1.) It's Carmen because she study like 1 hour and more time because she study 5:45-7:20.

2.) 66

3.) 360 minutes

4.) 400 dekameters

5.) He was 2.4 meters tall 2 years ago.

In centimeter, 240 cm.

Step-by-step explanation:

1.) wala

2.) How?

In this question you can apply trial and error or guess and check

Since 20 kg=20,000 g we can make it more easier in this form, so he can not exceed to 20,000 g

20,000÷300=66.66

So I tried to multiply 300 by 66 I got 19,800 and then when I tried 300×67 the product became 20,100 and since he can't exceed to 20,000 so the answer is 66

3.) 6 x 60 = 360

4.) FORMULA - multiply the length value by 100

4 X 100 = 400 dekameters

5.) 30 centimeters in meters is 0.3

Subtract 0.3 from his height.

2.7m - 0.3m = 2.4m
