Mark and Matthew signed up to walk in a 5K walk/run race. They predict it will take them 60 minutes to complete the race. Mark and Matthew finished the race in 53 minutes. What is the percent error? Round to the nearest tenth

Answer 1

To find the percent error, we need to calculate the difference between the predicted time and the actual time, divided by the predicted time and multiplied by 100.

The predicted time is 60 minutes.
The actual time is 53 minutes.

The difference between the predicted and actual time is 60 - 53 = 7 minutes.

Now, we can calculate the percent error:

Percent Error = (|Predicted Time - Actual Time| / Predicted Time) * 100

Percent Error = (|60 - 53| / 60) * 100

Percent Error = (7 / 60) * 100

Percent Error = 11.67

Rounded to the nearest tenth, the percent error is 11.7%.

Answer 2

Use the conversion ratio 1 liter equals 1,000 milliliters. A cylinder holds 6,750 milliliters. How many liters does it hold?(1 point)

6,750,000

Answer 3

To convert milliliters to liters, divide the number of milliliters by 1,000.

In this case, the cylinder holds 6,750 milliliters.

6,750 milliliters ÷ 1,000 = 6.75 liters

Therefore, the cylinder holds 6.75 liters.

Answer 4

Use the ratio 1 gallon equals about 3,785 milliliters. A container holds 34,065 milliliters. How many gallons does the container hold

Answer 5

To convert milliliters to gallons, divide the number of milliliters by 3,785.

In this case, the container holds 34,065 milliliters.

34,065 milliliters ÷ 3,785 = 9 gallons

Therefore, the container holds 9 gallons.
