Applying the percentages, and considering that 70% of the first group drinks at least 2 glasses of water a day, it is found that 0.725 = 72.5% of the team drinks at least 2 glasses of water a day.
The team is divided into two equal groups, hence, each represents 50%.
The <em>percentages </em>associated with drinking at least 2 glasses of water a day is:
- 70% of 50%(first group)
- 75% of 50%(second group)
Hence, applying the weighed percentage, the total percentage is:
0.725 = 72.5% of the team drinks at least 2 glasses of water a day.

times larger than the volume of the smaller on
c) Riley is not correct, the surface area of the larger aquarium is 9
times the surface area of the smaller one
2.
a) There are 8 boxes of office supplies can be packed into
the larger box for shipping
b) The surface area of the shipping box is 567 inches²
Step-by-step explanation:
1.
a) * Lets study the first aquarium:
- The formula for volume is V = l × w × h
∴ It is a rectangular box of dimensions 16 in , 8.5 in , 10.5 in
∴ Its volume = 16 × 8.5 × 10.5 = 1428 inches³
* The full capacity of this aquarium is 1428 inches³
- Riley noticed that it 3/4 full of water, then still can fill with
1/4 to be full
- Why 1/4 because 1 - 3/4 = 1/4
∴ The volume of 1/4 the aquarium = 1/4 × 1428 = 357 inches³
* There are 357 inches³ of water more would be required to fill the tank
b) * Lets talk about the larger aquarium
- Each dimension will be triple to construct the larger aquarium
- That means we will multiply each dimension of the small aquarium by 3
- That means the ratio between each dimension in the larger
aquarium to the smaller aquarium is 3 : 1
∴ The ratio between their volumes will be (3 : 1)³
- Because we will multiply each dimension by 3 and they
are 3 dimensions, that means 3 × 3 × 3 ⇒ 3³
∴ The ratio between their volumes = 27 : 1
∴ Riley is not correct because the volume of the larger aquarium is 27
times larger than the volume of the smaller aquarium
c) * Similar for the surface area of the larger aquarium
- Each dimension will be triple to construct the larger aquarium
- That means we will multiply each dimension of the small aquarium by 3
- That means the ratio between each dimension in the larger
aquarium to the smaller aquarium is 3 : 1
∴ The ratio between their surface area will be (3 : 1)²
- Because we will multiply each dimension by 3 and to get the
surface area we multiply each two dimensions for the six faces
and then add them
∴ The ratio between their surface area = 9 : 1
∴ Riley is not correct because the surface area of the larger aquarium
is 9 times larger than the surface area of the smaller aquarium
2.
a) * Lets think about this situation
- We want to fill some office supplies boxes of side length
4.5 inches inside the shipping box of dimensions 18 in , 9 in , 4.5 in
- That means the volume of the shipping box is how many times
the volume of the office supplies box
∴ The number of office supplies boxes = the volume of shipping box ÷ the volume of the office supplies box
∵ the volume of shipping box = 18 × 9 × 4.5 = 729 inches³
∵ the volume of the office supplies box = 4.5 × 4.5 × 4.5 = 91.125 inches³
∴ The number of office supplies boxes = 729 ÷ 91.125 = 8 boxes
* There are 8 boxes of office supplies can be packed into
the larger box for shipping
b) Look to the Net of the shipping box
- The net has 6 faces shaped rectangles
- Each two faces are congruent
- To find the surface area we will add all the areas of the 6 faces
- Two faces with dimensions 18 in and 9 in
∴ Their areas = 2 (18 × 9) = 324 inches²
- Two faces with dimensions 18 in and 4.5 in
∴ Their areas = 2 (18 × 4.5) = 162 inches²
- Two faces with dimensions 4.5 in and 9 in
∴ Their areas = 2 (4.5 × 9) = 81 inches²
∴ The total surface area = 324 + 162 + 81 = 567 inches²
* The surface area of the shipping box is 567 inches²
