Answer:
9/8 or 1.125
Step-by-step explanation:
We want to find the area of a rectangular postage stamp
The area of a rectangle can be found by multiplying the length by the width
Given length: 3/2
Given width: 3/4
Area = 3/2 * 3/4 = 9/8 or 1.125
Answer:
-1^2 = -1(-1)=1
Step-by-step explanation:
Answer:
a
Step-by-step explanation:
irration minus rathional is a irrational number
The ratio of the perimeters is 4/9, so the same applies to the side lengths
AB/HE = (x-2)/(2x)
AB/HE = 4/9
So,
(x-2)/(2x) = 4/9
9(x-2) = 2x*4 ... cross multiply
9x-18 = 8x
9x-8x = 18
x = 18
If x = 18, then
AB = x-2 = 18-2 = 16 units long
HE = 2x = 2*x = 2*18 = 36 units long
We know we have $4.40 for 4. Divide 4.40 by 4, you get 1.10. So it's $1.10 per notebook. Therefore, divide 6.60 by 1.10. You get 6, so you can get six notebooks with $6.60.
Hope this helps!
