$\bf \textit{recall that }\qquad i^2=-1\\\\
-------------------------------\\\\
|4+3i|~|4+3i|\implies (4+3i)(4+3i)\implies 16+12i+12i+9i^2
\\\\\\
16+24i+9(-1)\implies 16+24i-9\implies 7+24i$

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

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

3/5 of a number is 30. What's the number?

777dan777 [17]

To figure out the number we need to set up our equation to make more sense.

<u>3/5 = 30/x</u> (x is our missing number)

We know that what ever you do to the top of the fraction you can do to the bottom.

So if we multiply 3 x 10 we get 30.

Therefore to get the number we must multiply 5 by 10

5 x 10 = 50

So our answer and missing number is 50
