Amy bought 5 books for $0.50 and 7 for $.30, a total of 12
WORK
5 x .50 = 2.5
4.95 - 2.5 = 2.45
2.45 divided by .35 = 7
A decagon has 10 sides. If the polygon is symmetrical, the angle of rotation is given by the following equation:
360 / (number of sides)
Therefore,
360 = 10 = 36.
The interior angles are determined by the following equation:
180 - (angle of rotation)
Therefore,
180 - 36 = 144
The answer is A.
Please keep in mind that f(x)=log 1/2 (x+1) can also be written as:
f(x)=log ((x+1)/2)
The answer is 220 because you would just have to round 1 to 2 than everytging behind it is a zero
The answer is 1. Needs to be 20 chars.
