answer is 15%
Step-by-step explanation:
cost prices of book =160
selling prices of book =136
now,rate of discount =loss% (as discount only leads to some kind of loss)
so CP>SP
so loss=CP-SP =160-136=24
loss%= (loss/CP)÷100
=(24/160)÷100
=15%
so rate of discount =15%
Let the width be w.
The length is 5 yd less than twice the width, so the length is 2w - 5.
The area is LW, and the area is 52 yd^2
LW = A
(2w - 5)(w) = 52
2w^2 - 5w = 52
2w^2 - 5w - 52 = 0
2w^2 - 13w + 8w - 52 = 0
w(2w - 13) + 4(2w - 13) = 0
(2w - 13)(w + 4) = 0
2w - 13 = 0 or w + 4 = 0
2w = 13 or w = -4
w = 6.5 or w = -4
Since a width cannot be a negative number, discard the solution w = -4.
The width is 6.5 yd.
The length is 2w - 5 = 2(6.5) - 5 = 13 - 8 = 8
The length is 8 yd.
The length is 8 yd, and the width is 6.5 yd.
Answer:
A' = (- 5, - 1)
Step-by-step explanation:
The coordinates of point A = (- 6, 2)
Under the translation (x + 1, y - 3)
Add 1 to the x- coordinate of A and subtract 3 from the y- coordinate of A
A' = (- 6 + 1, 2 - 3) → A' = (- 5, - 1)
780 - (60*4)
540 - (65*6)
150/60
=2 and a half hours
Yes it is.
For every value of 'x' you can name, the value of 'y' is 5 .
If you mark several of those points on a graph, you see that
they form a straight line, which is horizontal and crosses the
y-axis at the point where 'y' is 5.
If the equation were not a linear one, its graph wouldn't be a straight line.
