Answer:
There are 5
Step-by-step explanation 5!= 5*4*3*2*1 = 120 different ways
The percent change from 36 to 63 is 63/36=1.75 (multiply by 100 to get a percentage) 175%
The percent change from 63 to 36 is 36/63=0.571=57.1%
Answer:
Yes it looks correct but that is just me
Step-by-step explanation:
Answer:
r = 4
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 5
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, r ) and (x₂, y₂ ) = (8, 9)
m = 
= 
= 9 - r = 5 ( subtract 9 from both sides )
- r = - 4 ( multiply both sides by - 1 )
r = 4
First things first, we have to find the number of people who share a room when there is 5 people to find how much the room would cost.
First multiply 36 by 5.
36 x 5 = 180
Now that we know that the total amount of the room costs 180 we need to divide that by 8 to see how much each person would end up paying if 8 people shared a room.
180 / 8 = 22.50
So the amount each person would pay is $22.50 if 8 people shared a room.
