Natalie purchased a used car for $12, 200 and had to pay 83 % sales tax. How much tax did she pay?
Fynjy0 [20]

Answer:

$5,533.33

Step-by-step explanation:

83% sales tax seems a lot, but ok.. anyway...i'm assuming that this is correct.

the final amount that she paid is made up of 2 parts:

100% of the car's price (list price of the car) + 83% of the cars price in taxes

if we add these together, that means she paid

100% + 83% = 183% of the car's price. We are told that this number is $12,200

hence,

183% --------> represents $12,200

1% ------------> represents $(12,200 ÷ 183)

amount in taxes = 83% -------> represents $(12,200 ÷ 183) x 83 = $5,533.33

A cylinder has a base radius of 6m and a height of 16m. What is its volume in cubic m,
SpyIntel [72]

Answer:

To the nearest tenth place, V = 1,810.3 m^3

Step-by-step explanation:

In this question, we are tasked with calculating the volume of a cylinder given its base radius and height.

Mathematically, the Volume can be calculated using the formula

V = pi * r^2 * h

where pi = 22/7 , r = 6m and h = 16m

Plugging these values, we have

V = 22/7 * 6^2 * 16

V = 22/7 * 36 * 16

V = 1,810.286 m^3

To the nearest tenth place, V = 1,810.3 m^3
