If she chooses the 8-inch tiles, she will need a quarter as many tiles as she would with 2-inch tiles.

denis23 [38]

In the above word problem, If she chooses the 8-inch tiles, she will need a quarter as many tiles as she would with 2-inch tiles, Quarter 8-inch tiles will cover the same area as one 2-inches.

<h3>What is the justification for the above?</h3>

Note that the area of the one 2-inch tiles is given as:

A1 = 4in²

The area of the quarter 8-inch tiles is:

A2 = 1/4 x 8 x 8

A2 = 16inch²

Divide both areas

A2/A1= 16/4

= 4

This implies she'll need four 2-inch tiles to cover the same amount of space as a quarter 8-inch tile.

Red

This is a circle with center (h, k) at (0,0) and radius (r) = 6

Formula: (x - h)² + (y - k)² = r²

Answer: x² + y² = 36

Blue

This is a circle with center (h, k) at (2,2) and radius (r) = 1

Formula: (x - h)² + (y - k)² = r²

Answer: (x - 2)² + (y - 2)² = 1

***************************************

Green:

This is a circle with center (h, k) at (-2,-2) and radius (r) = 1

Formula: (x - h)² + (y - k)² = r²

Answer: (x + 2)² + (y + 2)² = 1

***************************************

Purple:

This is an ellipse with center (h, k) at (0,-2) and radius on the x-axis (a) = 3 and radius on the x-axis (b) = 1

Formula: $\frac{(x-h)^{2}}{a^{2}} +\frac{(y-k)^{2}}{b^{2}}=1$

Answer: $\frac{x^{2}}{9} +(y+2)^{2}=1$

***************************************

Black:

This is a parabola with vertex (h, k) at (0,-6) and vertical stretch (a) = -1

Formula: y = a(x - h)² + k

Answer: y = -x² - 6

Set up an equation to find x, Explain why you used this equation

stiv31 [10]

Answer: 180= 38+(17x+1)+(3x+1), All the angles in a triangle add up to 180 degrees, so I made all the add measures equal to 180 degrees.

Just solve that equation to find x. Then used then plug in the x value to (17x+1). After you solve that put it equal to 2y to solve for y.

So the y equation would look like: 2y=(17x+1) (but you would have solved for x and then plugged it in to the equation)

If you need help solving or have any questions let me know!
