Mrs. Rowan allotted 30 minutes at the beginning of class for her students to complete an exam. The last student took 42 minutes to complete. What is Mrs. Rowan's percent error?

40%

Step-by-step explanation:

Percentage Error

From the question,

the approximated time=30 minutes.

Change in time= approximated time minus exact time = 42-30=12 minutes

This implies:

Hence Mr. Rowan's percent error

is 40%

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
