Step-by-step explanation:
The percent of 64 which that is 16 is 25% because, to find what percent a number y is of a number x, you have to follow the steps: Divide y by x.
add up the purchases
2(9.95) + 14.95
19.90 +14.95
34.85
now find the sales tax
34.85 * .06 =2.091 = 2.09 (round to 2 decimal places with money)
add the purchases and the sales tax to get the total amount
34.85 + 2.09
$36.94

Step-by-step explanation:
<u>Step 1: Define</u>
Equation: A = πr²
Given: π = 3.14, r = 3
<u>Step 2: Evaluate</u>
- Substitute: A = 3.14(3)²
- Exponents: A = 3.14(9)
- Multiply: A = 28.26
First solve the triangle:
75° + 75° + x = 180°
150° + x = 180°
x = 180° - 150°
Therefore x = 30°
Then, use the geometrical property of vertically opposite angles.
Therefore. x° = 30°
