For the first one, I believe I is 1200
A) Y=0.12x and the Y value is dependent whole X value is independent
b) Just make a table and multiple each value by the equation
c) The domain would be the lowest and highest values of X and the range would be the lowest and highest values of Y (double check me on this to be sure)
d) A day = (0.12)(300)+(0.12)(750)+(0.12)(1050)
A week = (0.12)(300)+(0.12)(750)+(0.12)(1050) and multiply that by 7
Now, to find how many people are not there, all you have to do is subtract the amount of seats and the people there.
112- 70= 42
Now since there are 7 seats per row and 42 is divisible by 7, you can divide 42 by 7.
42÷7= 6
So, 6 rows were empty.
9. Multiply the money he has by the portion he spent:
75 x 3/5 = (75 x3)/5 = 225/5 = 45
He spent $45
10. First rewrite 4 1/8 as an improper fraction
33/8
Now multiply by 1/3:
33/8 x 1/3 = (33 x1) /(8 x 3) = 33/24 = 1 3/8
She spent 1 3/8 hours studying math.
a common what? denominator?
