10-x-3x=7x-23
Add like terms (-x and -3x)
10-4x=7x-23
Add 4x to both sides
10=11x-23
Get 11x by itself by adding 23 to both sides
33=11x
divide by 11 on both sides to get x by itself
x=3

the ratio of men to women in a certain factory is 3 to 4. There are 198 men. How many workers are there?
vredina [299]
P r o p o r t i o n s

3:4 = 7

3/198 = 7/x

solve for x using cross multiplying

3/198 = 7/x

198(7) = 3x
1386 = 3x
/3         /3
   462 = x

Therefore, there are 462 workers.

Proof:

3/198 = 4/x
198(4) = 3x
792 = 3x
/3        /3
264 = x

264 + 198 = 462.

264 / 4 = 66
198 / 3 = 66
462 / 7 = 66

If a right circular cone is intersected by a plane that goes through both napped of the cone but not through the vertex, as in t
kramer

Answer:

F. Hyperbola

Step-by-step explanation:

In each napped, you'll have a parabola, combined they form an hyperbola.

It's one of the various shapes that can be produced by a plane intercepting a right circular cone, as you can see in the attached picture.

Each plane intersection is different, based on the angle and the position it passes through.

I hope that helps.

The automobile assembly plant you manage has a Cobb-Douglas production function given by p = 10x^0.2 y^0.8
Zepler [3.9K]

Answer:

The variation needed for the daily buget to follow the increase in production for the first year is 12.38 $/year.

This value of Δy is not constant for a constant increase in production.

Step-by-step explanation:

We know that the production function is p = 10x^{0.2} y^{0.8}, and in the current situation p=1200 and x=130.

With this information we can calculate the actual budget level:

p_0 = 10x^{0.2} y^{0.8}\\\\1200=10*130^{0.2} y^{0.8}\\\\1200=26.47*y^{0.8}\\\\y=(1200/26.47)^{1/0.8}=45.33^{1.25}=117.62

The next year, with an increase in demand of 100 more automobiles, the production will be p_1=1300.

If we calculate y for this new situation, we have:

y_1=(\frac{p_1}{10x^{0.2}} )^{1.25}=(\frac{1300}{26.47} )^{1.25}=49.10^{1.25}=130

The budget for the following year is 130.

The variation needed for the daily buget to follow the increase in production for the first year is 12.38 $/year.

\Delta y=y_1-y_0=130.00-117.62=12.38

This value of Δy is not constant for a constant increase in production.
