Answer:
27
Step-by-step explanation:
Answer:782
Step-by-step explanation: area equals length x width so your length is 23 and your width is 34 so you have to do 23x34
A. d=rt d is 32.12 and your rate is 8.8 so the answer for A is 32.12=8.8t
B. The word ascend means to go up
C. Just divide 32.12 by 8.8
12:20 = ![\frac{3}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D)
15:25 =
3:5 = ![\frac{3}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D)
9:15 = ![\frac{3}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D)
All the rectangles are similar because they all have identical lenght to width ratios.
Hope that helps!
Answer:the mass of the air inside the inflated balloon is 4 grams
Step-by-step explanation:
The initial mass of the balloon before it was inflated by the Math and Science class is 4 grams. After the balloon was inflated, the mass was 8 grams. This means that the mass by which the balloon increased would be the mass of the inflated balloon - the initial mass of the balloon. It becomes
8 - 4 = 4 grams.
Therefore, the mass of the air inside the inflated balloon is 4 grams.
