<h3>Answer: choice B) 120</h3>
=============================
Explanation:
1 yard = 3 ft, 1 ft = 12 inches
Based on those two facts, 1 yard = 36 inches (since 3*12 = 36).
So 25 yards = 900 inches after you multiply both sides by 25.
Divide this over 22 to get 900/22 = 40.909090909091 which rounds down to 40 (see note below). One ribbon gets us 40 pieces, so 3 of them will get 3*40 = 120 which is the answer
note: Why do we round down and not up even though we're really close to 41? Because Erika doesn't have 41 full pieces. Instead, she has 40 whole pieces plus a fraction that is close to 1, but it's not completely there. So we just ignore that fractional part.
Side note: this is assuming that she does not waste any of the fabric. Also keep in mind that the scissors has its own width (however small), so this will likely add a bit of waste. Each scissor slice produces a thin bit of fabric that can't be used. To make things simple, its ideal to ignore this fact.
5 over 2
Because if x = 4
3x4=12
12-6=6
15 over 6 simplified equal to 5 over 2
Answer:
Step-by-step explanation:
You didn't give much information, and it depends if your deck of cards includes a pair of Jokers.
There are 52 cards in a deck, not including Jokers, otherwise there are 54.
In a non-Joker deck the chances of drawing a King or 6 is 8/52 or roughly 15.4% in a deck with 2 Jokers your chance is 14.8%.

a. a^4 - 2ab^2 - 2ab^2 + 4b^4 = a^4 - 4ab^2 + 4b^2
b. 49x^2 - 14x + 1
c. 25a^2 - 20ab^4 + 4b^8
d. x^2 - 144
e. -16n^6 - 28n^3 + 28n^3 + 49 = -16n^6 + 49
