Complete question :

In the evening, the temperature is 2828 degrees. By midnight it has dropped 3131 degrees lower. Between midnight and 4 am, it goes down 66 more degrees. Then, by 9 am, the temperature goes up 3030 degrees. Find the final temperature.

Answer:

-38°

Step-by-step explanation:

Evening temperature = 28°

By midnight = 31° lower

4am = 66° lower

9 a.m = 30° higher

Temperature at midnight :

28° - 31° = - 2°

Temperature at 4 a.m:

-2° - 66° = - 68°

Final temperature at 9a.m :

-68° + 30° = - 38°

The temperature at 9a.m is - 38°

a class has 20 trays of paint each trays has 6 colors 1 of the color is red what fraction of the colors in the 20 trays is red
Molodets [167]

Answer: it is 1/6

You can solve by saying, 1 out of 6 in each tray is red, so my fraction should be 1/6.

It doesn't matter the amount of trays because the pattern is always the same.

But if you want to check it out you can do it in this way.

You know there is 1 red color per tray, if there are 20 then you'd have 20 of them, in each tray there are 6 colors so the total is 120.

Now you solve it if there are 20 red colors out of 120 them the answer is 20/120, thus you get 1/6

Los nutriólogos recomiendan que una persona debe tomar en promedio 2.5 litros de agua en un día, para que esté bien hidratada. ¿
Goshia [24]

the question in English

Nutritionists recommend that a person should drink an average of 2.5 liters of water in a day, to be well hydrated. How many liters of water should a person drink in a month to comply with a good hydration (Consider a month equal to 30 days) Formulate an algebraic expression to determine the total liters of water that a person should drink a given number of days.

Let

x-------> the number of days

y------> the total liters of water

we know that

y=2.5x  ------> algebraic expression to determine the total liters of water that a person should drink a given number of days

For x=30 days (1 month)

substitute in the formula

y=2.5*30=75\ liters

therefore

<u>the answer is</u>

75\ liters
