Answer:

9 9/20

Step-by-step explanation:

4 1/5 * 2 1/4

Change the mixed nubers to improper fractions

4 1/5 = (5*4+1)/5 = 21/5

2 1/4 = (4*2+1) /4 = 9/4

21/5 * 9/4 = 189/20

Now we change it back to a mixed number

20 goes into 189   9 times   (20*9 = 180  with 9 left over)

9 9/20

Mekhanik [1.2K]

The sales tax percentage of the store manager report is 7.41%

<h3>How to solve for the sales tax percentage</h3>

Customers are subject to a charge known as sales tax when they buy goods and services.

It is a pass-through tax, which means you must collect it from clients and send the money to your state or local government. the seller do not contribute sales tax.

The sales tax is first calculated by

= price after tax - price before tax

= 513 - 475

= 38

sales tax percentage is calculated using the formula

= (Tax amount / Price before tax) × 100%

= (38 / 513) * 100

= 7.4074

= 7.41%

A 12-foot ladder is placed four feet from the base of a wall.
nikitadnepr [17]

Answer:8sqrt 2 or sqrt 128

Step-by-step explanation:

We can use the Pythagorean Theorem. Since the ladder is leaning against the wall, it is the hypotenuse. It is also 4 feet away from the wall so 12^2-4^2=b^2 b^2=128 so b=8sqrt 2 or sqrt 128.
