To find out how many miles Hong would run in 20 minutes, we need to find the rate at which he is running. This can be done by dividing the distance by the time:
Rate = Distance / Time
In this case, the distance is 3 miles and the time is 25 minutes.
Rate = 3 miles / 25 minutes = 0.12 miles per minute
Now, to find out how many miles Hong would run in 20 minutes, we can multiply the rate by the time:
Distance = Rate * Time
Distance = 0.12 miles per minute * 20 minutes = 2.4 miles
Therefore, Hong would run 2.4 miles in 20 minutes.
Hong runs 3 miles in 25 minutes. At the same rate, how many miles would he run in 20 minutes?

A construction crew is lengthening a road that originally measured 15 miles. The crew is adding one mile to the road each day.
Let L be the length (in miles) after D days of construction.
Write an equation relating L to D. Then graph your equation using the axes below.
Let L be the length (in miles) after D days of construction.
Write an equation relating L to D. Then graph your equation using the axes below.
The equation relating L (length in miles) to D (number of days) can be written as:
L = 15 + D
This equation represents the initial length of the road (15 miles) plus the number of additional miles added each day (D), resulting in the total length of the road after D days.
To graph this equation, we can plot the values of L on the y-axis and the values of D on the x-axis. Since the initial length is 15 miles, the graph will start at the point (0, 15). Then we can use the equation to find additional points to plot on the graph. For example, after 1 day of construction (D = 1), the length will be:
L = 15 + 1 = 16
So the point (1, 16) can be plotted. Similarly, after 2 days of construction (D = 2), the length will be:
L = 15 + 2 = 17
So the point (2, 17) can be plotted, and so on.
The resulting graph will be a straight line with a positive slope of 1, indicating that the length of the road is increasing by 1 mile each day.
Here is a graph illustrating this equation:

Translate the sentence into an equation.
Twice the difference of a number and 2 equals 8.
Use the variable b for the unknown number.
Twice the difference of a number and 2 equals 8.
Use the variable b for the unknown number.
The sentence "Twice the difference of a number and 2 equals 8" can be translated into the equation:
2 * (b - 2) = 8
In this equation, b represents the unknown number. The difference of the number and 2 is calculated by subtracting 2 from b. Then, this difference is multiplied by 2 to get twice the difference. The result should be equal to 8.
2 * (b - 2) = 8
In this equation, b represents the unknown number. The difference of the number and 2 is calculated by subtracting 2 from b. Then, this difference is multiplied by 2 to get twice the difference. The result should be equal to 8.
Find the volume of this rectangular pyramid.
Be sure to include the correct unit in your answer.
5cm, 3cm, and 8cm
Be sure to include the correct unit in your answer.
5cm, 3cm, and 8cm
To find the volume of a rectangular pyramid, we can use the formula:
Volume = (1/3) * base area * height
The base area of a rectangular pyramid can be calculated by multiplying the length and width of the base. In this case, the length is 5 cm and the width is 3 cm, so the base area is:
Base area = 5 cm * 3 cm = 15 cm^2
Next, we need to determine the height of the pyramid. In this case, the height is given as 8 cm.
Now we can plug these values into the volume formula:
Volume = (1/3) * 15 cm^2 * 8 cm
= (1/3) * 120 cm^3
= 40 cm^3
Therefore, the volume of the rectangular pyramid is 40 cm³.
Volume = (1/3) * base area * height
The base area of a rectangular pyramid can be calculated by multiplying the length and width of the base. In this case, the length is 5 cm and the width is 3 cm, so the base area is:
Base area = 5 cm * 3 cm = 15 cm^2
Next, we need to determine the height of the pyramid. In this case, the height is given as 8 cm.
Now we can plug these values into the volume formula:
Volume = (1/3) * 15 cm^2 * 8 cm
= (1/3) * 120 cm^3
= 40 cm^3
Therefore, the volume of the rectangular pyramid is 40 cm³.

Find two consecutive whole numbers that √18 lies between.
To find the two consecutive whole numbers that √18 lies between, we can start by calculating the square root of 18:
√18 ≈ 4.24264
The whole numbers closest to this square root are 4 and 5.
Therefore, √18 lies between the consecutive whole numbers 4 and 5.
√18 ≈ 4.24264
The whole numbers closest to this square root are 4 and 5.
Therefore, √18 lies between the consecutive whole numbers 4 and 5.
