Granny Smith, who was leaving Montreal, boarded a train at four minutes past the hour. After boarding, she stuck her head out of the window and shouted to the ticket man, "How far are we from Toronto?" "All trains take five hours either way," he replied. "How many trains shall I meet on the way?" asked Granny. "A train leaves Toronto at five minutes past the hour, every hour," Answered the ticket men. How many trains will Granny Smith meet?

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

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)

answer: 800
