Solution: The correct option is option (B) 1.08(0.87y).
Explanation:
It is given that the original cost of cards is y. It is also given that cards was on sale of 13% and the tax in the country is 8%.
There is a sale of 13% it means the prices are 13% less.
13% of y = 
The price of cards after discount is
The price after discount is 0.87y.
It is given that the tax in the country is 8%.
The amount of tax on the cards is calculated as shown below,
The price after discount is is calculated as shown below,
Therefore, the correct option is option (B) 1.08(0.87y).
Divide 16 by 20 to find the percent.
16/20 = 0.8 = 8%
To check, multiply 20 by 0.08
20 x 0.08 = 16

Answer:
The value of x = 8.1 units
Step-by-step explanation:
<em>Note: I am assuming we have to determine the value of the side 'x'.</em>
Given
Angle Ф = 32°
To determine:
x = ?
Using the trigonometric ratio
tan Ф = opposite / adjacent
here
Ф = 32°
opposite to angle 32° = x
adjacent to angle 32° = 13
Therefore,
substituting adjacent = 13, Ф = 32°, opposite = x in the equation
tan Ф = opposite / adjacent
x = 8.1 units tan 32° = 0.62
Therefore, the value of x = 8.1 units
Answer:
A =63.76512739 in^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi * r
28.3 = 2* 3.14 *r
28.3 = 6.28r
Divide each side by 6.28
28.3/6.28 = 6.28r/ 6.28
4.506369427 =r
Now we need to find the area
A = pi r^2
A = 3.14 (4.506369427)^2
A =63.76512739 in^2
