Answer:

594 rpm

Step-by-step explanation:

Two gears will have the same linear speed, so:

v₁ = v₂

ω₁ r₁ = ω₂ r₂

(316 rpm) (79) = ω (42)

ω ≈ 594 rpm

Pls help, 20 points!!
klemol [59]

Answer:

(-18,9)

Step-by-step explanation (work shown in picture attached):

1) The first step in solving by substitution is to isolate the y-term in one of the equations if it is not already isolated. Isolate y in the first equation by dividing both sides by -2. This leaves us with the equation y = \frac{-x}{2}

2) Now, substitute \frac{-x}{2} for the y in the second equation. Simplify and isolate x. (You can multiply everything by -2 to get rid of the fraction.) This leaves us with x = -18.

3) We've found the x-value of the solution, -18. Now, substitute -18 for x back into one of the original equations (I chose the first one because it was simple) and isolate y. This gives us y = 9. Thus, in point form, the answer is (-18,9).

The points (2,-5) and (5,r) lie on a line with slope 2. Find the missing coordinate r.
Andrew [12]

Answer: r = 1

Step-by-step explanation:

The slope of a line can be represented as \frac{y_2-y_1}{x_2-x_1}.  Plugging in the following values would provide you with:

\frac{(r)-(-5)}{(5)-(2)} =2

\frac{r + 5}{3}  = 2

r + 5 = 6

r = 1

Hope it helps :) and let me know if you want me to elaborate on anything.
