Answer:

See explanation

Explanation:

Average heart beat = Number of heart beats/ time

7.0 years = 7.0 * 365 * 24 * 60 = 3679200 minutes

If there are 69 beats in 1 minutes

There are x beats in 3679200 minutes

x = 253865 beats

x = 254000.00 beats ( to 3 sf)

beats in 7.00 years = 254000.000 beats

beats in 7.000 years = 254000.0000 beats

Statement:

The best way to measure the mass of an orange is to use a balance. You put the orange and the mass pieces in the same cup on the balance and find out how many centimeters it is. The mass of my orange was 145.

Explanation:

Problem 1

The student has not done a good job in measuring the weight of the orange. In fact, the has complicated his simple problem.

Reasons:

  • Using the mass pieces and the cup to find the weight of the orange is wrong approach.

     He can easily place the orange on the balance and read off the weight.

  • Centimeters is a unit of length. What length is he measuring and recording?

    The unit of weight is in newtons(N).

  • Mass is not read from a balance. A balance gives the weight of substance. Mass is different from weight.

Problem 2

Rewriting to paragraph to correct the errors:

The best way to measure the mass of an orange is to use a balance. You put the orange on the balance and find out how many newtons it is. The weight in newtons can be converted to mass in kilogram. The mass of my orange will be 145kg.
