Step-by-step explanation:
The dollar amount of the reduction was $200 - $140, or $60.
$60 is what percentage of $200?
$60
---------- = 3/10 = 0.30
$200
The reduction was 30%; the jacket sold for 70% of its original price.
Answer:
For a circle of radius R, the perimeter is:
P = 2*pi*R
Where pi = 3.14
If we have a section of this circle, defined by an angle θ, the length of that arc is calculated as:
L = (θ/360°)*2*pi*R
In this case, we have a unit circle, so the radius is 1 unit, and we have a section defined by an angle of 57°.
Then the total distance traveled will be equal to the length of the arc, which is:
L = (57°/360°)*2*3.14*(1 unit) = 0.99 units
Then the correct option is a.
(as we want to find the total distance, the starting point does not matter, so the total distance traveled in a section of 57° would be the same in any point of the circle, this means that the fact that we should start at the point (1,0) has no effect in this question)
21/25 is the highest score
Divide 21 by 25 and you will get .84
Which is 84%
