What is the formula to calculate the temperature change?

Back

Temperature change = Final temperature - Initial temperature.

Front

If the temperature at 6:00 pm is 24°F and it drops 36°F, what is the new temperature?

Back

New temperature = 24°F - 36°F = -12°F.

Front

What is the scale factor in a scale drawing?

Back

The scale factor is the ratio of a length in the drawing to the corresponding length in reality.

Front

If a scale drawing is 1 inch = 3 feet, how do you find the actual dimensions of a room that is 8 inches by 6 inches?

Back

Actual length = 8 inches * 3 feet/inch = 24 feet; Actual width = 6 inches * 3 feet/inch = 18 feet.

Front

How do you calculate the area of a rectangle?

Back

Area = Length × Width.

Front

What is the area of a room that is 24 feet long and 18 feet wide?

Back

Area = 24 feet × 18 feet = 432 square feet.

Front

What is the formula to find the time taken if distance and speed are known?

Back

Time = Distance ÷ Speed.

Front

If Stephen ran 1/4 mile in 1/8 hour, what is his speed in miles per hour?

Back

Speed = (1/4 mile) ÷ (1/8 hour) = 2 miles per hour.

Front

How do you calculate the total time taken to run a race if the distance is known?

Back

Total time = Total distance ÷ Speed.

Front

If a race is 5 miles long and Stephen runs at 2 miles per hour, how long does it take him to finish?

Back

Time = 5 miles ÷ 2 miles/hour = 2.5 hours.
