Answer:
C
Step-by-step explanation:
It is not A or B because the line is not dotted.
It is not B or D because y should be greater than x
So it is C
24: 1, 2, 3, 4, 6, 8, 12,
24120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20,
24, 30, 40, 60, 120
The
GCF of
24 and
120 is
24.
Answer:
2.32 gallons of paint
Step-by-step explanation:
First, find the area of all 4 sides of the room, with the equation A = lw
11(10)
= 110 (for 2 of the walls)
18(10)
= 180 (for the other 2 walls)
Add these up:
110 + 110 + 180 + 180
= 580
Then, divide this by 250:
580/250
= 2.32
So, 2.32 gallons of paint will be needed to paint the room.
The final price is the cost plus the tax.
Since we know the tax and a percent, we can write this as
T = C(1+r)
T = what Graham paid = $87.45
C = cost before tax
r = tax rate expressed as a decimal = .40
Plugging in what we know
87.45 = C (1+.4)
87.45 = C(1.4)
Divide both sides by 1.4
C = $62.46
