Since the scale of 2 cm to 3m is the scale that Janice is using, yes the ratio would be 2:3 so William is correct
Answer:
Mona will save a total of $7 by going to Carpet World.
Step-by-step explanation:
First, we need to calculate the total area of the floor by multiplying the width by the length...
5m * 8m = 40m
Now we calculate the amount that it would cost to buy the carpet from each of the establishments. For the first establishment, we can buy 16
and get the next 8 half off and that would leave another 16 at full price. The second establishment we have a 5% off (0.95 of official price) for every 8, since out total area is 5 times this amount then our total will have a 5% off.
Establishment 1: (16 * 2.20) + (8 * 1.10) + (16 * 2.20) = $79.20
Establishment 2: (40 * 1.90) * 0.95 = $72.20
Difference: 79.20 - 72.20 = $7
Mona will save a total of $7 by going to Carpet World.
3x^2-18x+24
3(x^2-6x+8)
3(x-4)(x-2)
14.142 inches is my answer. You would use the Pythagorean theorem for this by the way.
The exact value of the cone is the answer corresponding with B
