D is the answer. Putting this because it has to be 20 characters
5. 53.96 - 19.99 = 33.97
33.97 / 53.96 = 0.629 = 63%
6. a 62% discount means she would pay 38% of the original price
2.15 * 0.38 = 0.82 . the 0.82 is not the discount, but the amount she would actually pay.
to check: the discount is 62% 2.15 x 0.62 = 1.33
2.15 - 1.33 = 0.82
Note absolutely sure on part 7
7. A) the number of votes per vertical line is missing.
B) darken the vertical lines and total the number of colored squares there are then divide the number the winner got by total so 6/16 = 0.375 = 37.5% MAY NEED TO ROUND TO 38%
C) amber got 2/16 squares = 0.125. 420 * 0.125 = 52.5 = 53 votes
Is this a triangle? if so witch is the leg and the hypotenuse
It works the same way if it begins negative, the negative in front of the 'x' terms just means that the hyperbola opens vertically.
'b' refers to distance from center to vertices in the 'y' direction because 'b' is with y term.
The vertices are at (0, +-4), b = 4
To find 'a' use the slope of the asymptotes.
slope = b/a = 4/a
Estimate slope by using a point that is farthest away from orgin, (10,20.5)
The asymptote will be slightly below the point (10,20)
This gives a slope of 20/10 = 2.
4/a = 2 ----> a = 4/2 = 2
Answer: a = 2, b = 4
Explain how using partial quotients to divide is similar to using the distributive property to multiply
