M∠CBD = 60°
BD = BC = 10 (radius)
m∠BCD = m∠BDC = 60°
equilateral triangle
CD = BC = 10

m∠CAD = 90°
AD = AC (radius)
m∠ACD = m∠ADC = 60°
AC = CDsin(45) ; pythagorus
= 10/sqrt(2) = 5sqrt(2)

(y+20)=1(x+10); First, we can find the slope by using the equation y2-y1/x2-x1.

-9+20/1+10 (Accounting for double negatives).

11/11 = 1

The slope of the equation is 1, now we just need to pick a set of points from which we derived the slope from (doesn't matter which) as y1 and x1 in the point-slope equation. (y-y1)=m(x-x1)

Your final answer can either be (y+20)=1(x+10) or (y+9)=1(x-1) but in the context of this question it is (y+20)=1(x+10)

Your plant runs two assembly lines. The first line produces 1,250 units a day and the second produces 2,825 units a day. What is
Step2247 [10]

Answer:

\frac{50}{113}

Step-by-step explanation:

The ratio is simply the division of one by another (and simplification).

Hence, <u>the ratio of production of the first line to the second line</u> is 1250 divided by 2825. So,

Ratio = \frac{1250}{2825}=\frac{50}{113}
