Answer 9

A company makes two sizes of boxes shaped like rectangular prisms. The large box is
16
16 inches tall,
10
10 inches wide, and
10
10inches long. The drawing shows the dimensions of the small box.








Part A



What is the maximum number of small boxes that can fit inside the large box?








Part B



The company plans to increase the width and length of the large box by
4
4 inches each to create a new larger box. How many more of the small boxes will be able to fit inside this new larger box compared to the original large box?

Answer 11

part 1 one wrong

Answer 12

B
C

Answer 13

13.2-8x

Answer 14

We know that the two expressions are equivalent, so their coefficients must be equal.

The coefficient of x in the first expression is 21.2, while in the second expression it's 5.3*4 = 21.2. Therefore, c = -2.6.

Answer 15

Let's equate the coefficients of x in both expressions:

For 21.2x in the first expression, the coefficient is 21.2.

For 5.3(4x) in the second expression, the coefficient is 5.3 * 4 = 21.2.

So, the value of c when the expressions are equivalent is 0.

Answer 16

True
False
False
True

Answer 17

To find the value of x when the scale mapping Figure A onto Figure B is 1:7⅕, we set up the proportion:

1/7 = x/14

Cross multiplying:

7x = 14
x = 2

Therefore, the value of x is 2.

Answer 18

I apologize for the mistake.

Given that the ratio is 1:7⅕, we convert the second value to a fraction first:

7⅕ = 7 + 1/5 = 36/5

Now, we set up the proportion:

1 / 36/5 = x / 14

To solve for x, we take the reciprocal of 36/5 and multiply:

x = 1 * 14 / (36/5)
x = 14 * 5 / 36
x = 70 / 36
x = 35 / 18

Therefore, x = 35/18.

Answer 19

The correct answers are:

False - The factory uses 4 gallons of water when it is in operation for 4000 hours. Since the relationship is proportional, if 4000 hours corresponded to 4 gallons, the true statement would be that it uses 1 gallon of water when in operation for 1000 hours.

True - Point W represents the number of gallons of water used when the factory is in operation for 7 hours. This is correct if Point W on the graph shows the consumption for 7 hours.

False - The factory uses 9000 gallons of water when it is in operation for 9 hours. This is not true based on the proportional relationship shown in the graph.

Answer 20

I am unable to physically drag objects. However, the solution to the inequality 6x - 4 < 8 is:

6x - 4 < 8
6x < 12
x < 2

So, the arrow should be placed on the number line to the left of 2 to represent the solution.

Answer 21

First, let's calculate the dimensions of the small box:

Width: 10 - 2 (lost due to the overlap from the larger box) = 8 inches
Height: 16 - 2 = 14 inches
Length: 10 - 2 = 8 inches

Part A:
Volume of the Large Box = 16 * 10 * 10 = 1600 cubic inches
Volume of the Small Box = 8 * 14 * 8 = 896 cubic inches

Maximum number of small boxes that can fit inside the large box = 1600 / 896 ≈ 1.79
Therefore, the maximum number of small boxes that can fit inside the large box is 1.

Part B:
Volume of the New Larger Box = (16 + 4) * (10 + 4) * (10 + 4) = 20 * 14 * 14 = 3920 cubic inches

Maximum number of small boxes that can fit inside the new larger box = 3920 / 896 ≈ 4.38

4.38 - 1.79 ≈ 2.59

Therefore, 2 more small boxes will be able to fit inside the new larger box compared to the original large box.

Answer 22

I apologize for the errors in my previous responses. Let's calculate the correct answers this time.

Part A:
Volume of the Large Box = 16 * 10 * 10 = 1600 cubic inches
Volume of the Small Box = 8 * 14 * 8 = 896 cubic inches

The maximum number of small boxes that can fit inside the large box = 1600 / 896 = 1.7857, but since you cannot fit a fraction of a box, the maximum number is 1 small box.

Part B:
Volume of the New Larger Box = (16+4) * (10+4) * (10+4) = 20 * 14 * 14 = 3920 cubic inches

The maximum number of small boxes that can fit inside the new larger box = 3920 / 896 = 4.375, but since you still cannot fit a fraction of a box, the maximum number in this case is 4 small boxes.

Additional small boxes that can fit inside the new larger box compared to the original large box: 4 - 1 = 3 small boxes.

Answer 23

Let's correct the answer for Part A:

Part A:
Volume of the Large Box = 16 * 10 * 10 = 1600 cubic inches
Volume of the Small Box = 8 * 14 * 8 = 896 cubic inches

The maximum number of small boxes that can fit inside the large box = 1600 / 896 = 1.7857

So, the maximum number of small boxes that can fit inside the large box is 1.
