Two Cars Start at the Same Point and travel in the Same Direction at the average speeds of 70 miles per hour, and 40 miles per h

cestrela7 [59]

Answer:

You can check it by solving it in your head. They are separating at the rate of 55-40 or 15 miles per hour. So in 1 hour or 60 minutes they'll be 15 miles apart, so in 20 minutes they'll be 5 miles apart, so in 40 minutes they'll be 10 miles apart. So it has to be 40 minutes.

Step-by-step explanation:

55t-40t=10

15t=10

15t/15=10/15

2/3

40 Minutes

Explain why congruent figures have the same surface area?

Hatshy [7]

Congruent means exactly the same, so congruent figures have the same surface areas because they have the exact same size in each side.

Find each percent increase round to the nearest percent from $5 to $8

IRISSAK [1]

There are at least a few ways to do it, one of them being:

$8 - $5 = $3, so we may want to find out how much percent of 5 is 3.

3 = x% of 5
3 = x/100 * 5
3 = x/20 * 1
3 = x/20 / * 20 (both sides)
x = 60 [percent]

So now we know that 3 is 60% of 5. It also means that the increase from $5 to $8 was by <u>60%</u><u />.

If you have the average production function: APL=3L2 - 0.05L3, the function of marginal product of labour, MPL is

Sveta_85 [38]

Answer:

<h2>The marginal product of labor function or MPL= $9L^{2}-0.2L^{3}$ .</h2>

Step-by-step explanation:

The Average Production Function or APL is given as $APL=3L^{2}-0.05L^{3}$ where "L" represents the overall amount labor in the production process.
Therefore, the Total Production Function or TPL,in this case, would be $TPL=(3L^{2}-0.05L^{3})\times L$ = $TPL=3L^{3}-0.05L^{4}$
Hence,the Marginal Product of Labor, which is abbreviated as MPL will be= $\frac{dL}{dTPL}=(3\times 3L^{2})-(4\times 0.05L^{3})$ = $9L^{2}-0.2L^{3}$
Therefore,the marginal product of labor function or MPL= $9L^{2}-0.2L^{3}$
