First, we get the area of each tile: (100 cm = 1m)
.20 m* .15 m = 0.03m^2
Then, we solve for the total area of the wall:
5m*3m= 15m^2
Then we divide 
15/0.03 = 500 tiles

gayaneshka [121]

Answer:

The amount deducted for Ms.Everett‘s paycheck for her health insurance premium is $307.6

Step-by-step explanation:

given information:

annual insurance = $12304

employer pay annually = 70%

first we calculate the annual insurance paid by the employer

employer paid annual insurance = 70% x $12304

                                                      = $8612.8

then, we calculate the insurance paid by Ms. Everett annually

Ms. Everett paid annual insurance =  $12304 - $8612.8

                                                         = $3691.2

thus, amount is deducted for Ms.Everett‘s paycheck for her health insurance premium

Ms. Everett's paycheck deduct = $3691.2/12

                                                     = $307.6

The population of a city is about 200,000 and is growing at a rate of 0.6% per year.
IgorC [24]
A)

\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=P(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &200000\\
r=rate\to 0.6\%\to \frac{0.6}{100}\to &0.006\\
t=\textit{elapsed time}\to &t\\
\end{cases}
\\\\\\
A=200000(1+0.006)^t\implies A=200000(1.006)^t

B)    \bf A=200000(1.006)^4

A triangle has sides with lengths of 28 millimeters, 34 millimeters, and 43 millimeters. Is it a right triangle?
dezoksy [38]
To find if it's a right triangle, we use the Pythagorean Theorem of a² + b² = c² where a and b are the legs of the triangle (the shorter measurements) and c is the hypotenuse (the biggest measurement).

28² + 34² = 43²
784 + 1156 = 1849
1940 ≠ 1849

No. This is not a right triangle. The sum of the squares of the shorter measurements (AKA the legs) do not equal the square of the biggest measurement.

What would be the best graph or display to represent your home library statistics data why
choli [55]
For presenting home library statistical data you could use a pie chart. The parts can be things like various genres, or based on writers, or anything similar. You could make a lot of different ones about various statistical data about books and it would still be the best choice.
