Diego pours 6.8 ounces of water from a full bottle. he estimates that he poured out 20% of the water in the bottle. about how much water was in the full bottle?

There is 34 ounces of water in the bottle initially and this can be determined by using the unitary method.

Given :

The following steps can be used in order to determine the total amount of water in the full bottle:

Step 1 - The unitary method can be used in order to determine the total amount of water in the full bottle.

Step 2 - According to the given data, Diego pours 6.8 ounces of water from a full bottle which is the 20% of the water in the bottle.

Step 3 - If 20% is 6.8 ounces of water than the 100% is given by:

Multiply 6.8 by 100 in the above expression.

Divide 680 by 20 in the above expression.

= 34 ounces

So, there is 34 ounces of water in the bottle initially.

Full bottle can fill 34 ounces water and 27.2 ounces left in the bottle

Step-by-step explanation:

Full bottle : 100%

6.8 ounces: 20%

100% / 20% = 5

Full bottle = 6.8 x 5 = 34 ounces

water remain in bottle = 34 -6.8 = 27.2 ounces

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
