What is the approximate percent change in a temperature then went down from 120゚ to 100゚ the person changes approximately 17% th
Zanzabum

Answer:

The answer is 17%

explanation:

One way to find percents is to multiply the number you're trying to find the percent of (120) by whatever percent you're looking for (0.17, 0.2, 0.8, etc) If you multiply 120*0.17, you'll get about 20, which is how much was the amount of degrees lost.

In a soccer game the winner gains 3 points, while the loser gains 0 points. If the game is a draw, then the two teams gain 1 poi
Mariana [72]

Answer:

10 losses

Step-by-step explanation:

Here, we want to get the greatest possible number of games the team lost

Let the number of games won be x

Number drawn be y

Number lost be z

Mathematically;

x + y + z = 38

Let’s now work with the points

3(x) + 1(y) + z(0) = 80

3x + y = 80

So we have two equations here;

x + y + z = 80

3x + y = 80

The greatest possible number of games lost will minimize both the number of games won and the number of games drawn

We can have the following possible combinations of draws and wins;

26-2

25-5

24-8

23-11

22-14

21-17

21-17 is the highest possible to give a loss of zero

Subtracting each sum from 38, we have the following loses:

10, 8, 6, 4, 2 and 0

This shows the greatest possible number of games lost is 10
