You times the numerator by the numerator and the denominator by the denominator
thats all
Answer:
10.99 feet
Step-by-step explanation:
The arc length when an angle of 360° is made is the perimeter of the circle.
Perimeter = π*Diameter = π*30 = 94.25 ft
To know the arc length when an angle of 42° is made, we need to use the following proportion
94.25 ft / x ft = 360° / 42°
x = 42/360*94.25
x = 10.99 ft
First you need to find the amount for each of the items, then total it up:
T-shirts> 9.50 x 2 = 19
Socks> 7.95 x 3 = 23.85
Shoes> 49.95
Total: 19 + 23.85 + 49.95 = $92.80
Next find the tax:
(to find the taxes you multiply the total by the percent)
92.8 x 0.06 = 5.57
-- then add the amount to your item total
92.8 + 5.57 = 98.37
~OR~
You could multiply the item total by 1.06 so that you wouldn't have to add to taxes to the previous total because it is already part of the equation
92.8 x 1.06 = 98.37
