Answer:

The answer is D

Step-by-step explanation:

Begin by disturbing the exponent amongst the equation.

Answer: ( 64g^9 h^6 k^12)

Then do division

( 64g^9 h^6 k^12) / 8g^3 h^2= (8g^6 h^4 k^12)

Distribution of exponent

(h^5 k^3)^5 = (h^25 k^15)

Put the answers together

(8g^6 h^4 k^12) - (h^25 k^15)

That's the answer, hope it helps!

Iesha’s quality-control manager told her she must have 97% of her clocks functioning properly. She found a report that said 6 ou

Masja [62]

Answer:

Keisha’s experimental probability is 1/50.
When the inventory is 4000 clocks, the prediction is that 3920 clocks will work.
Keisha will have more than 97% of the products working.

Step-by-step explanation:

These are three prediction that Keisha can make based on the report that said 6 of 300 clocks tested weren't working.

Base on that information, Keisha can calculate an experimental probability, dividing clocks that don't work properly by the total amount of clocks:

$P_{clocks} = \frac{6}{300}=\frac{1}{50} = 0.02 (or 2\%)$

Therefore, the probability of success is 100% - 2% = 98%.

This means that Keisha has a probability of having 98% of all clocks functioning properly. So, she can make the prediction: from 4000 clocks, 3920 will work. Also, she can predict that she will actually have more than 97% working, because the experimental probability is higher than that.

The vertices of a polygon are P(0,4), Q(5,4), R(5,−3) and S(0,−3). What is

andrezito [222]

Answer:

Perimeter of the polygon p = 24

Step-by-step explanation:

Step(i):-

Given the vertices of a polygon are

P(0,4) ,Q( 5,4) ,R( 5,-3) and S(0,-3)

The distance of PQ

$a = PQ = \sqrt{(4-4)^{2} +(5-0)^{2} } = \sqrt{25} =5$

The distance of QR

$b = Q R= \sqrt{(-3-4)^{2} +(5-5)^{2} } = \sqrt{49} =7$

The distance of RS

$c = RS = \sqrt{(0-5)^{2} +(-3+3)^{2} } = \sqrt{25} =5$

The distance of PS

$d = PS = \sqrt{(0-0)^{2} +(-3-4)^{2} } = \sqrt{49} =7$

Step(ii):-

Perimeter of the polygon

= sum of all sides of polygon

p = a+ b+ c+ d

p = 5+7+5+7

p = 24

Final answer:-

Perimeter of the polygon p = 24

A company policy requires that, for every 40 employees, there must be 3 supervisors. If the are 285 supervisors at the company h

Inga [223]

Answer:

11,400.0

Step-by-step explanation:

There needs to be 40 employees per every 3 supervisors, so this means multiplication, or division, but I went with the multiplication route.

285 x 40 = 11,400.

11,400 / 40 = 285.

The reason I multiplied 285 by 40 is because the supervisors was the main piece to the puzzle, and was much easier than if it gave you employees first, and that's when you'd divide by 3.

If there's 285 supervisors, you have the full amount of supervisors, now you need employees, so you are free to multiply by 40, since thats how many supervisors are available every 40 employees. I hope this helps.

(a)

we are given

The average distance from the sun to the planet Venus is about 261,000,000 km

we have to write in scientific form

In scientific form , we write expression in terms of exponent of 10

so, we can write as

$261,000,000 km=261*100000km$
