Hello from MrBillDoesMath!
Answer:
Choice B, -2 sqrt(85) / 85
Discussion:
By definition,
cos(@) = length of side adjacent to angle / hypotenuse
= -2/ ( sqrt ( (-2)^2 + (9^2) ) (usin Pythag. theorem)
= -2/ sqty (4 + 81)
= -2 / (sqrt(85)
Multiply numerator and denominator by sqrt(85):
= (-2 / ( sqrt(85) ) * (sqrt(85)/sqrt(85) )
= -2 sqrt(85) / 85
which is choice B
Thank you,
MrB
The width of the rectangle would be 6 times the first rectangle and the length would be 8 times the first rectangle.
<u>Explanation:</u>
Given:
Two rectangles are proportional.
Length and width of 1 rectangle = 6 : 8
Dimensions of the other rectangle = ?
Let length and width of the other rectangle be x : y
According to the question:


So, the width of the rectangle would be 6 times the first rectangle and the length would be 8 times the first rectangle.
Hey there! :D
Subtract 20% by 10%, because it is asking how much less than the original price was by what percent.
20%-10%= 10%
The ticket was 10% less than the original ticket.
I hope this helps!
