Step-by-step explanation:

the first thing you have to do is to get the x and the y axis and add them to then decrease that by o,5 and then you get f of which you multiply it by 2 adn you get your answer.

<span>Taylor Street.
I am assuming that the Lombard street is the famous Lombard street in San Francisco, California. With that assumption, after going East 3 blocks, you'll reach the intersection of Lombard and Jones. After going south 2 blocks, you'll reach the intersection of Jones and Filbert. Finally, after turning left and going 1 block, the first intersection will be Taylor Street.</span>

The diagram below shows twelve 30-60-90 triangles placed in a circle so that the hypotenuse of each triangle coincides with the

julia-pushkina [17]

Answer:

m+n = 337

Step-by-step explanation:

Lets start from the first triangle, It is given to be as 30-60-90.

The hypotenous of first rectangle be 2x, then other sides are by default x and

$\sqrt{3}(x)$ , using laws of trigonometry.

(sin(30) = 0.5 and cos(30) = $\frac{\sqrt{3}}{2}$ )

The perimeter of first triangle is ,

= $2x + x + \sqrt{3}(x) = x(3+\sqrt{3}) = \sqrt{3}x(1+\sqrt{3})$

Now, for second triangle, the longer leg is 2x, and similarly again,

other 2 sides are $\frac{2x}{\sqrt{3}} and \frac{4x}{\sqrt{3}}$ .

Again the perimeter of triangle comes out as,

= $\sqrt{3}(x)(1+\sqrt{3})(\frac{2}{\sqrt{3}})$

Thus, the repeating pattern is identified. The consecutive perimeters differ by, multiplying by factor $\frac{2}{\sqrt{3}}$

Thus, we can say that perimeter of 4th triangle is,

= $(\frac{2}{\sqrt{3}})^{3}(X)$ , where X is the repeating constant.

And of 12th triangle is,

= $(\frac{2}{\sqrt{3}})^{11}(X)$ ,

Evaluating the above ratio, we get,

= $\frac{81}{256}$

Thus, m =256 and n=81.

Thus, m+n = 256+81 = 337.

You are designing a large rectangular fish tank for your tropical fish. The length will be 1 yard 3 inches, the width will be 1.

Andrej [43]

One yard is 36 inches, 1.5 feet is 18 inches.

So the answer is...

(36+3)*18*20

= 39*18*28

= 702*28

= 19,656

The graph of a curve that passes the vertical line test is a?

agasfer [191]

The graph of a curve that passes the vertical line test is known as a function. Functions are graphical representations that may have multiple x-values for a given y-coordinate, but will never have multiple y-values for any given x-coordinate.
Hope that helped! =)
