On average, Ms Johnson the English teacher takes 15 minutes to mark an English assignment. If there are 38 learners in class, how long should it take Ms Johnson to mark all the assignments? Answer in hours ​

9 Hours and 30 minutes.

Step-by-step explanation:

on average Ms Johnson takes 15 minutes to mark one English assignment. So to find how long it takes to mark all 38 assignments, mulitply.

15(38)=570 minutes. The problem specifically states to answer in hours. 1 hour is 60 minutes.

570÷60= 9.5.

9 hours and half an hour,

which is 9 hours and 30 minutes.

9hours and 30 minutes

Step-by-step explanation:

15x38=570

it takes Ms Johnson 570 minutes

570min=9h 30min

hope this helped

have a great day!!

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
