Find the annual interest rate. Round your answer to the nearest hundredth of a percent. I=$160.67, P=$2000, t=8 monthsI=$160.67,

Keith_Richards [23]

Answer:

The annual interest rate is 12.05%.

Step-by-step explanation:

The simple interest is given by the formula:

$I=\dfrac{P\times R\times T}{100}$

Where I denotes interest.

P denotes the principal amount.

R denotes the rate of interest

and T denotes the time period.

I=$160.67, P=$2000, t=8 months=8/12 years (Since 12 months=1 year so 1 month=1/12 year)

$160.67=\dfrac{2000\times R \times \dfrac{8}{12}}{100}\\\\R=12.05%$

Hence, the annual interest rate is 12.05%.

Tyler is laying tile on his rectangular kitchen floor. The dimensions of the floor are 16 1/2 feet by 15 feet. If he is using sq

blondinia [14]

First, find the area for the kitchen floor: 16.5*15=247.5 squared feet
Then find the area for one tile: 0.5*0.5=0.25 squared feet
Finally, divide the mayor area between the minor: 247.5/0.25= 990 tiles.

Also you can do it in this another way:
First, divide length of the kitchen floor between the length of one tile: 16.5/0.5=33
Then, do the same for the height: 15/0.5=30
Finally multyply both results: 33*30= 990 tiles.
