If Brian’s brother took the boys to the mall at 11:30 AM and left at 1:45 PM, how much time did the boys spend at the mall?

2  hours 15  minutes

Step-by-step explanation: 45 - 30 is 15 so now you just have to subtract the hours and since 11:00 only goes to 12 you would go to one after that so 1:00 is like 13 so 11 - 13= 2 so your answer is 1 hours and 15 minutes

2 hours and 15 minutes.

Step-by-step explanation:

Add 30 to 11:30 to 12:00. Add 45 to that to get 1 hour and 15 minutes. Then add the other hour.

answer: idk

step-by-step explanation:

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)
