If i can finish 1 class every 2 days how many days would it take to finish 42 classes
kherson [118]

Answer:

84 days

Step-by-step explanation:

If you can finish 1 class in 2 days then that can be expressed as:

1C = 2D

C = 2D

How many days would it take to finish 42 classes? Multiply both sides by 42:

42C = 2D * 42

42C = 84D

Therefore, it will take 84 days to finish 42 classes.

Students at a middle school were surveyed on how they get to school. Out of 230 students, 10% said they ride their bikes to scho
Fittoniya [83]

Answer:

10% is equivalent to the unit fraction 23

To find 10% of 230, multiply 230 by 0.10

10% of 230 is 23

Think about it, if 100% of 230 is 230, and 10% is 23, you can multiply 23 x 100 to get 230. I took a while to answer, but I hope my explanation helps.

Alan estimated that he would score 140 points the next time he bowled. He actually scored 152 points. What was the percent error
slava [35]
Given:
estimate = 140
actual = 152

Percent of error = |(estimate - actual)/actual|  * 100%

% of error = |140 - 152| / 152 * 100%
                 = |-12|/152 * 100%
                 = 0.0789 x 100%
% of error = 7.89%  rounded to the nearest tenth 7.9%

Explain why the absolute value of a number will never be negative
aleksandr82 [10.1K]
The absolute value of a number will never be negative because absolute value is the distance from zero, so it will always be positive. For example, you can't be -6 away from 0, you are 6 away from 0.
