%change=100(final-initial)/initial
%change=100(25-40)/40=-37.5%
So Denise received a discount of 37.5% off the regular price.
Answer: The third one or C
Answer:
520 ft
Step-by-step explanation:
A straight road to the top of a hill is 2500 feet long and makes an angle of 12 degrees with the horizontal. Find the height of the hill.
base angle = 12 deg
hypotenuse = 2500
----
height = 2500*sin(12) = 519.78 ft
Do 520 ft if rounded
In this case just change the variables by the numbers. (1,5)
x=1 y=5
1^2 + 5^2 = 26
1+25=26
26=26 *this one is the answer...
TRUE
x2 + y2 = 16
1^2 + 5^2=16
1+25=16
26=16
False
x2 + y2 = 13
1^2 + 5^2=13
1+25=13
26=13
False
x2 + y2 = 11
1^2 + 5^2=11
1+25=11
26=11
False
So we can say that the first one is the answer.
