The falling distance of the glasses is 8 meters.

<h3>How to calculate the distance</h3>

From the information, the hotel’s balcony was 5 meters from the ground floor and he dropped his glasses to the bottom of the hotel’s pool that was 3 meters deep.

Therefore the falling distance will be:

= 5 - (-3)

= 5 + 3

= 8

The falling distance of the glasses is 8 meters

Answer:

David find <u>8</u> quarters.

Step-by-step explanation:

Given:

David was in need for some money so he decided to clean out the water fountain at the mall he found 20 nickels and quarters.

The collection of nickels and quarters totaled to 2.6.

Now, to find the quarters David find.

Let the number of nickels be x

And the number of quarters be y

Thus, the number of nickels and quarters he found:

x+y=20.

⇒ x=20-y.........( 1 )

The totaled of nickels and quarters:

0.05x+0.25y=2.6

(As 1 nickel=$0.05 and 1 quarter=$0.25)

Now, putting the equation ( 1 ) in the place of x we get:

0.05(20-y)+0.25y=2.6

⇒ 1-0.05y+0.25y=2.6

⇒ 1+0.20y=2.6

<em>Subtracting both sides by 1 we get:</em>

⇒ 0.20y=1.6

<em>Dividing both sides by 0.20 we get:</em>

⇒ y = 8.

So, the quarters = 8.

Therefore, David find 8 quarters.

When a number is decreased by 20% of itself, the result is 128. what is the number?
andriy [413]
The number was 160 because 5/4•128=160. 5/4 represents inverting 80% and multiplying it by the number to determine how the result became 128. For checking over all you have to do is do 4/5 or 80%•160 which shall give you 128.
