Michael thought he could read 23 pages of his book in class. He was only able to read 20. what is his percent error
Cerrena [4.2K]
Percent error is calculated using

((Actual - predicted) / actual) * 100

In this case, the actual value of the number of pages he read is 20. The expected value was 23. So simply plug in:

((20 - 23) / 20) * 100 = -15%

Anna is in a cave 42 feet below the cave entrance. She descends 10 feet, then ascends 15 feet. Find her new position relative to
Mademuasel [1]

Answer:

Her new position is 37 feet below the cave entrance

Step-by-step explanation:

Let us solve the question

∵ The cave entrance is the zero position

∵ Anna is in 42 feet below the cave entrance

→ Below zero means negative

∴ Anna is in -42 feet

∵ She descends 10 feet

→ Descend means negative

∴ She is in -42 + -10 = -52 feet

∵ She ascends 15 feet

→ Ascend means positive

∴ She is in -52 + 15 = -37 feet

→ -37 means she is in below the cave entrance by 37 feet

∴ Her new position is 37 feet below the cave entrance
