Answer:

The area of the semi-circle

A = 1320.37 cm²

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given the diameter of the circle 'd' = 58cm

The radius of the circle 'd' = 2r

$r = \frac{d}{2} = \frac{58}{2} = 29$

The area of the semi-circle

$A = \frac{1}{2} \pi r^{2}$

$A = \frac{1}{2} (3.14) ((29))^{2}$

A = 1320.37 cm²

What is the slope of a line perpendicular to the line whose equation is x-3y= -18 Fully simplify your answer.

qwelly [4]

Answer:

-3

Step-by-step explanation:

Isolate -3y by subtracting x from both sides

-3y = -18 - x

Divide everything by -3

y = 6 + 1/3x

Slope is 1/3, and perpendicular lines have the reverse reciprocal slope, so our slope is -3

What is the ratio of x to y?

abruzzese [7]

$\frac{3}{2} = \frac{2x}{2x+y}$

From any proportion, we get another proportion by inverting the extremes (or the means):

$\frac{2x+y}{2} = \frac{2x}{3}$ = k

so we have:

2x=3k
2x+y=2k therefore:
3k+y=2k
y= - k

x= $\frac{3}{2} k$

$\frac{x}{y}$ = - $\frac{3}{2}$

The corect answer is A. -3/2

or:

$\frac{3}{2} = \frac{2x}{2x+y}$

From any proportion, we get another proportion by inverting the extremes and the means:

$\frac{2x+y}{2x} = \frac{2}{3}$

We use a property of proportions:

$\frac{a}{b} = \frac{c}{d}$ where a, d are extremes and b,c are means and the product of the extremes equals the product of the means (a*d=b*c),

so we have

$\frac{a-b}{b} = \frac{c-d}{d}$ or

$\frac{a+b}{b} = \frac{c+d}{d}$ (you can check this also by "the product of the extremes equals the product of the means")

$\frac{2x+y}{2x} = \frac{2}{3}$

$\frac{(2x+y)-2x}{2x} = \frac{2-3}{3}$

$\frac{y}{2x} = \frac{-1}{3}$

3y = - 2x

$\frac{x}{y} = -\frac{3}{2}$
