Answer:
32.40
Step-by-step explanation:
The shirts were 40% of the regular price
The sale price of 1 shirt was
18*40% = sale price
18*.40 =7.20
He bought 3 shirts, so multiply by 3
3 * 7.2 =21.60
He paid 21.60
The price he would have paid without the discount is
18*3 = 54
The savings is
54- 21.60 =32.40
1. Would be 58/11
Because we convert the mixed number to an improper fraction, 5x11+3/11. We then would multiple the numbers with gives us 55+3/11. We add that giving us 58/11

Area = PI * radius^2
Circumference = 2 * PI * radius
radius = Circumference / 2 * PI
So, Area = PI * (Circumference / 2 *PI) * (Circumference / 2 *PI)
So, Area = Circumference^2 / (4*PI)
To determine the number of subjects that are needed for the experiments, we multiply the number of independent variables with the number of scores. For example, there are n independent variables then, there are approximately,
number of subjects = 20 x n = 20n
