Find the unit rate for number of parts manufactured per hour if 1116 parts are made in 7 hours. Round to the nearest integer.A. 209 parts/h

B. 127 parts/h

C. 159 parts/h

D. 183 parts/h

Answers

Answer 1

Answer: The unit rate is obtained by dividing the amount of work done by the unit time. In the problem, we are already given the total number of parts manufactured (amount of work done) and the total amount of time to manufacture (7 hours).

Obtaining the unit rate is as simple as dividing 1116 parts by 7 hours, as shown below:

Unit rate = 1116 parts / 7 hours
Unit rate = 159.42857

Therefore the unit rate is approximately 159 parts/h.

This whole ugly thing is just 6 numbers that are all multiplied.
Here they are:

   (-7) · (x⁶) · (y⁻³) · (5) · (x⁻¹) · (y) .

To help you see what's going on, I'm going to rearrange them
and write them in a different order. (You'll remember that when
you multiply, the order of the numbers doesn't matter.)

    (-7)·(5)   ·   (x⁶)·(x⁻¹)   ·   (y⁻³)·(y) .

I'll bet you can see it already. It's really starting to fall apart.

Remember that when you have to multiply the same base to
different powers, you just add the powers.

So here's the multiplication:

   (-7)·(5)   ·   (x⁶)·(x⁻¹)   ·   (y⁻³)·(y) .
   |    |       |
      -35 · x⁵ ·       y⁻²

   -35 x⁵ y⁻²

   or you could write it as -35x⁵ / y²   which is the same thing.

What is the equation of the line described below written in slope-intercept form? the line passing through point (0, 0) and parallel to the line whose equation is 3x + 2y - 6 = 0 y =-2/3 -x y =-3/2x y = 3/2x

Answers

Since the line in question is parallel to the line with the equation 3x+2y-6=0, it can be said that they have the same slope. To find the slope of the line with the given equation, transform the given equation to its corresponding slope-intercept form. Hence, the equation is now

y=(-3/2)x+3

the slope is then -3/2

and since the line in question passes through the origin, the equation of this line is then

y=(-3/2)x+0
or simply
y=(-3/2)x

Answer:

y=(-3/2)x
