Answers

Answer:

A) See below

B) (7,11)

C) (7,11)

Step-by-step explanation:

Part B:

I chose the example (7,11)

y = 1/7x + 10

y = 2x -3

I am going to use substation and set the equations equal to each other and solve for x.

1/7 x + 10 = 2x - 3 Subtract 1/7x from both sides

10 = 2x - 1/7 x -3

10 = 14/7 x - 1/7 x - 3

10 = 13/7 x - 3 Add 3 to both sides

13 = 13/7 x multiply both sides by 7/13

7 = x

Substitute 7 for x in either of the original equations

y = 2x - 3

y = 2(7) - 3

y = 11

The solution is (7,11)

Part C - Check:

y = 1/7x + 10

11 = 1/7(7) + 10

11 = 1 + 10

11 = 11 checks

y = 2x - 3

11 = 2(7) - 3

11 = 14 - 3

11 = 11 checks

Answers

Given:
1 drink:
4/8 cup of yogurt ;
1 cup of ice;
5/8 cups of banana slices ;
2/8 cups of blueberries

Part A. 6 drinks. How many total cups of blueberries and banana slices will she use to make 6 drinks?

5/8 cups banana slices * 6 drinks = 5/8 * 6 = (5*6)/8 = 30/8 cups of banana slices.

2/8 cups of blueberries * 6 drinks = 2/8 * 6 = (2*6)/8 = 12/8 cups of blueberries

30/8 + 12/8 = 42/8 cups of banana slices and blueberries

Part B
4/8 cups of yogurt * 6 drinks = (4*6)/8 = 24/8 = 3 cups of yogurt
1 cup of ice * 6 drinks = 6 cups of ice

The perimeter of a rectangle is 34 units. Its width is 6.5 units. What is its length?

Answers

If the width is 6.5 then double that to work out the two widths which would be 13. Take that from the perimeter so you're left with 21. Half 21 to work out one length which is 10.5. Length = 10.5

Which of the following representative fractions would indicate the largest scale map? Options: • 1:1 • 1:0 • 1:1,000,000 • 1:24,000

Answers

Final Answer:

The largest scale map is indicated by the representative fraction 1:1. Option A is correct.

Explanation:

In cartography, the representative fraction (RF) of a map indicates the scale of the map, specifically the ratio between a distance on the map and the corresponding distance on the Earth's surface. A larger RF value means a larger scale map, which represents smaller areas with more detail.

Now, let's compare the given options:

1. 1:1 - This RF means that one unit on the map represents one unit on the ground, essentially a one-to-one scale. It doesn't get any larger than this, so this is the largest scale possible.

2. 1:0 - This doesn't make sense in cartography because you cannot represent the Earth's surface with zero on one side of the ratio. It's an invalid option.

3. 1:1,000,000 - This RF indicates that one unit on the map represents one million units on the ground. This is a much smaller scale compared to 1:1, so it represents a much larger area with less detail.

4. 1:24,000 - This RF means that one unit on the map represents 24,000 units on the ground. While this is a larger scale than 1:1,000,000, it is still smaller than 1:1, which is the largest scale.

In summary, the largest scale map is represented by 1:1. Option A is the answer.

Answer:

The representative fraction (RF) of a map indicates the scale of the map. In a representative fraction, the first number represents a unit of measurement on the map, and the second number represents the corresponding unit of measurement in the real world.

Among the options provided, a larger scale map would have a smaller second number because it means that one unit of measurement on the map represents a smaller unit of measurement in the real world. So, the largest scale map in the given options is:

1:24,000

In this case, 1 unit on the map represents 24,000 units in the real world, indicating a very detailed and large-scale representation of the area.
