The unit price for a hot dog is $1.95, because this is the result of dividing $5.85 by 3. This means that 8 hot dogs would cost $15.60.
Thomas has finished 4 problems of his weekly math homework. If he needs to solve a total of 20 problems, which of the following shows the equivalent of the percentage of his math homework Thomas still needs to complete?
A. 20/100
B. 80/100
C. 0.20
D. 0.08
A. 20/100
B. 80/100
C. 0.20
D. 0.08
Thomas still needs to complete 20 - 4 = 16 problems.
To find the percentage of his math homework Thomas still needs to complete, we can calculate (16 / 20) * 100%.
This is equivalent to (0.8) * 100% = 80%.
Therefore, the correct answer is B. 80/100.

When x = 8, what does y equal?
x + y = 24
A.
y = 3
B.
y = 8
C.
y = 16
D.
y = 32
x + y = 24
A.
y = 3
B.
y = 8
C.
y = 16
D.
y = 32
To find the value of y when x = 8, we can substitute x = 8 into the equation x + y = 24 and solve for y.
When x = 8:
8 + y = 24
Subtracting 8 from both sides gives:
y = 24 - 8
y = 16
Therefore, when x = 8, y = 16.
The correct answer is C. y = 16.
When x = 8:
8 + y = 24
Subtracting 8 from both sides gives:
y = 24 - 8
y = 16
Therefore, when x = 8, y = 16.
The correct answer is C. y = 16.

The measure that provides information on how much the prices vary is the range.
The range is calculated by subtracting the lowest value from the highest value in a set of data.
In this case, the lowest price is $22,650 and the highest price is $24,350.
The range is $24,350 - $22,650 = $1,700.
Therefore, the correct answer is A. the range.
The range is calculated by subtracting the lowest value from the highest value in a set of data.
In this case, the lowest price is $22,650 and the highest price is $24,350.
The range is $24,350 - $22,650 = $1,700.
Therefore, the correct answer is A. the range.
When cooking a certain type of rice, the ratio of water to rice should always be 3 to 2. The table below shows this relationship.

To maintain the ratio of 3 parts water to 2 parts rice, we can use proportions.
To find the amount of water corresponding to 6 cups of rice, we set up the proportion:
3/2 = 6/x
Cross-multiplying, we get:
3x = 12
Dividing both sides by 3, we find that:
x = 4
Therefore, the correct value for the water when there are 6 cups of rice is 4 cups.
For 10 cups of rice, we can again set up the proportion:
3/2 = 10/x
Cross-multiplying:
3x = 20
Dividing both sides by 3:
x = 20/3
Therefore, the correct value for the water when there are 10 cups of rice is approximately 6.67 cups.
The completed table is as follows:
Water (cups) - Rice (cups)
3 - 2
6 - 4
10 - 20/3
To find the amount of water corresponding to 6 cups of rice, we set up the proportion:
3/2 = 6/x
Cross-multiplying, we get:
3x = 12
Dividing both sides by 3, we find that:
x = 4
Therefore, the correct value for the water when there are 6 cups of rice is 4 cups.
For 10 cups of rice, we can again set up the proportion:
3/2 = 10/x
Cross-multiplying:
3x = 20
Dividing both sides by 3:
x = 20/3
Therefore, the correct value for the water when there are 10 cups of rice is approximately 6.67 cups.
The completed table is as follows:
Water (cups) - Rice (cups)
3 - 2
6 - 4
10 - 20/3
