An artist is using tiles and boards for a project. A tile has length 1/3 ft and width 1/3 ft. A board has length 1/4yd and width

Nezavi [6.7K]

We have been given that

The length of the tile is given by 1/3 feet.

The width of the tile is given by 1/3 feet.

The length of the board is given by 1/4 yd.

The width of the board is given by 1/4 yd.

We know that 1 feet = 0.33 yard

Hence, we have

The length of the tile = $\frac{1}{3} \cdot 0.33= 0.11$ yd

The width of the tile = $\frac{1}{3} \cdot 0.33= 0.11$ yd

Hence, the ratio of length of the tile to the length of the board is given by

$\frac{0.11}{1/4} \\
\\
\frac{44}{100} \\
\\
\frac{11}{25} \\$

Area of tile = $0.11 \times 0.11 = 0.0121$ square yd.

Area of board is $\frac{1}{4} \times \frac{1}{4} = \frac{1}{16}$

Therefore, the ratio of the area of the tile to the area of the board is given by

$\frac{0.0121}{1/16} \\
\\
\frac{121}{625}$

Solve: 2cos(x)-square root 3=0 for 0 less than x less than 2 pi

Leona [35]

Answer:

The general solution of $cos x = cos(\frac{\pi }{6})$ is

x = 2nπ± $\frac{\pi }{6}$

The general solution values

$x = - \frac{\pi }{6} and x = \frac{\pi }{6}$

Step-by-step explanation:

Explanation:-

Given equation is

$2cosx-\sqrt{3} =0 for 0$

$2cosx =\sqrt{3}$

Dividing '2' on both sides, we get

$cos x =\frac{\sqrt{3} }{2}$

$cos x = cos(\frac{\pi }{6})$

General solution of cos θ = cos ∝ is θ = 2nπ±∝

Now The general solution of $cos x = cos(\frac{\pi }{6})$ is

x = 2nπ± $\frac{\pi }{6}$

put n=0

$x = - \frac{\pi }{6} and x = \frac{\pi }{6}$

Put n=1

$x = 2\pi +\frac{\pi }{6} = \frac{13\pi }{6}$

$x = 2\pi -\frac{\pi }{6} = \frac{11\pi }{6}$

put n=2

$x = 4\pi +\frac{\pi }{6} = \frac{25\pi }{6}$

$x = 4\pi -\frac{\pi }{6} = \frac{23\pi }{6}$

And so on

But given 0 < x< 2π

The general solution values

$x = - \frac{\pi }{6} and x = \frac{\pi }{6}$

The salaries of 235 nurses were recorded and analyzed. The analyst later found that the highest salary was incorrectly recorded

madam [21]

The correct answer is A. Mean

Explanation:

In the analysis of numerical data, means refers to the average value. This is found by adding all the values, in this case, all the salaries and then dividing the total by the total of values, in this case, 235. This sample statistic is affected by each of the values that are added, due to this, if a value changes or was corrected, the mean needs to be revised. Also, this does not occur in the case of the minimum (lowest value), the median (value in the middle), or in the mode (most frequent value.)
