If a light bulb is off; how can you tell that It has been used recently? ANSWER ASAP
Ierofanga [76]

If you have a second fixture around, you can use the same test of putting a tube in a working socket and see if it lights. It is not uncommon in fluorescent fixtures to have the ballast burn out. You may detect a burnt smell or see the bulbs flickering.

sasho [114]

Given:

The solution decreased by \dfrac{9}{8} ounces every hour for 5 hours.

Remaining solution at the end of the experiment = \dfrac{99}{8} ounces.

To find:

The initial amount of solution.

Solution:

Let the initial amount of the solution be x.

The solution decreased by \dfrac{9}{8} ounces every hour for 5 hours.

Total decreased amount  =\dfrac{9}{8}\times 5

                                          =\dfrac{45}{8}

Initial amount = Remining amount + Decreased amount of solution.

x=\dfrac{99}{8}+\dfrac{45}{8}

x=\dfrac{99+45}{8}

x=\dfrac{144}{8}

x=18

Therefore, the initial amount of solution is 18 ounces.
