Some vinyl records (let's call them "Oldies") rotate at the rate of 78 rpm (revolutions per minute). The chart below shows revolutions per minute for three different tracks on another type of vinyl record (called "Goodies").

Which has a greater rate of revolutions per minute, Oldies or Goodies?

(Choice C)

C

the rates are the same

(A ) Oldies

Step-by-step explanation:

Goodies

First, we determine the revolution rate per minute of the Goodies.

Revolution rate per minute

Since the oldies have a rate of 78 revolutions per minute;

78 rpm. >45 rpm.

We therefore conclude that the Oldies has a greater rate of revolutions per minute.

The correct option is A.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

answer: its the third option.
