Matt, a 180 pound (82 kg) male, goes to a party and is served beer in a 16-ounce (473 ml) red plastic cup. he has 3 cups of beer

4 Standard drinks he has consumed in over a two - hour time period.

<h3>What is Unitary Method?</h3>

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

For example: 5 cars have price of $500. what will be the price of 10 cars.

Now, we know

5 cars → $500

1 car → $500/5

1 car → $100

10 cars → 8 x $100

10 cars → $800

The standard drink contains 12 - ounce of beer.

Here, we have given 1 red cup which has 16 - ounce of beer.

He has 3 red cups.

So, total ounce of beer he has consumed in two hour time period:

16 x 3 = 48 ounce of beer.

Now, as we know standard drink contains 12 - ounce of beer.

so, Number of standard drink = 48/12 = 4

Hence, 4 Standard drinks he has consumed in over a two - hour time period.

On a number line, point D is at -6, and point E is at 8. Point F lies between points D and E. If DF: FEis 3: 1, where does point
Vadim26 [7]

F is located on the numbe<u>r 4.5</u><u> </u>on the number line.

<h3></h3><h3>Where does point F lie on the number line?</h3>

We know that point D is at -6

Point E is at 8.

Point F is between D and E, such that the ratio:

DF:FE is 3:1

So if we divide the distance between D and E in 4 parts, 3 of these parts are DF, and one of these parts is FE.

First, the distance between E and D is:

distance = 8 - (-6) = 14 units.

Now, if we divide that by 4, we get:

14/4 = 3.5

Then we have:

DF = 3*(3.5) = 10.5

This means that F is at 10.5 units to the right of D, then:

F = D + 10.5 = -6 + 10.5 = 4.5

F is located on the numbe<u>r 4.5</u><u> </u>on the number line.

total score= 299 + 1596 = 1895

total mean= 1895 ÷ (13+28) = 1895 ÷ 41
