Answer:

  c = 92/n

Step-by-step explanation:

The equation that describes the inversly proportional relationship is ...

  y = k/x

The value of the constant of proportionality can be found from ...

  xy = k . . . . . . product of values of independent and dependent variables

__

In this problem, we have c = 23 for n = 4, so the constant of proportionality is ...

  k = c×n = (23)(4) = 92

The equation for the relationship is ...

  c = 92/n

Consider a steel ball floating on the surface of mercury in a half-filled container. What happens when the rest of the container
Helen [10]

Answer

The steel ball will be caught up in between the mercury and water medium.

Step-by-step explanation:

  • Mercury with a density of 13546 kg/m^3
  • water with a density of 1000 kg/m^3
  • Steel with a density of 8050 kg/m^3

From the factual density of both substances given above ,it shows that mercury is more heavier than water. In that case mercury will be at the lower layer when mixed with water.

The steel ball will be caught in between both mixtures as the density of  steel is 8050 kg/m^3.Which  is more than Water but less than Mercury.

10. Daniels goes to the shopping center. He has a bank account with a
Savatey [412]

Answer:

-$36

Step-by-step explanation:

Daniel has a starting balance of $259, so anything he spends will be deducted by this amount. To find out how much he spent, we need to add up everything he bought.

He spent $45 + $150 + $100, adding to a grad total of $295.

To find out how much money Daniel has left, we need to subtract his purchases from his funds. This would be $259 - $295. This leaves you with a final answer of -$36 in Daniel's bank account.

Rasek [7]
Just multiply both dimensions by 2 to make it into centimeters.

Therefore,

4*2 x 5*2 (in inches) will be:

8cm x 10cm (in centimeters)

We conclude that the dimensions of her postcard into a graphic on her web page will be 8x10 in centimeter units. 

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
