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.
Because ΔABC ≅ ΔHJK
AB = HJ (corr. sides, ≅ Δs)
HJ = 3.5cm
Answer:
B. 9 : 21
Step-by-step explanation:
Multiply numerator and denominator by 3:
... 3/7 × 3/3 = 9/21 ⇒ 9 : 21
_____
Any denominator that is not a multiple of 7 will not work. 35 is a multiple of 7 (=5×7), but 12 (=4×3) is not the same multiple of 3.
Answer:
x = 19
Step-by-step explanation:
YZ || XW, so ∠Y = ∠W
if ∠Y = ∠W, then ∠W = 2x
since the sum of the angles of a triangle is 180 degrees:
(3x-5) + 2x + 90 = 180
x = 19
It is the first box, the one on the top left
