Effram buys a new set of golf clubs for $460. If a 9% sales tax is added on, how much will he pay in taxes?

Given:

Price of golf after tax = $460

Rate of sales tax = 9%

To find:

The amount of tax.

Solution:

Let x be the price of golf before tax.

According to the question,

Price of golf after tax = Price of golf before tax + tax

Divide both sides by 1.09.

So, price of golf before tax is $422.

Now,

Therefore, the amount of tax is $37.98.

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
