Answer:

To make sure they remain effective.

Step-by-step explanation:

A fire extinguisher is a portable device used to extinguish a fire.

Handheld extinguishers are pressurised with nitrogen or carbon dioxide and can be used in the kitchen or garage.

Fire extinguishers controls the amount of pollution caused by smoke and burning.

Although they have no expiring date, they won't last forever. Extinguishers should work for 5 to 15 years, but fire extinguishers be routinely maintained to make sure they remain effective.

Answer: the answer would be To make sure they remain effective.

Step-by-step explanation:

It wouldn't be to make sure they are up to code because fire extinguishers do not use code, code is used in electronics. For the second option and the last option it would not be this because they could be trained in a practice instead of using the real thing.

Step 2: add this value to the the integer part: 3 + 0.5555555555555556 = 3.5555555555555554. So,

Answer:

30

Step-by-step explanation:

All the degrees of a triangle should add up to 180 degrees.

D = F

D and F are not equal to 90.

If E = 30,  D and F both equal 75.

75(2) + 30 = 180.

1.To know this answer, we need to know some vocabulary that's used in t. Most people don't know how to solve questions if they have hard Vocabulary and what the question is Asking

Mean=The average of all his throws

It's asking us to calculate his total score  

2. Find Clues to help you solve word problems

Finding clues in Word Problems is a very important part a lot of people skip but this helps you solve the question easier

5 throws and Mean Score is 32 are the clues

3. Guess and check

The method to this thingy is called guess and check. There is another method which is slightly harder and i just don't want to do it.

Let's just say his scores were... 5, 6, 4, 5,10Add them up and you get 30Then 30/5

Let's try bigger numbers

20+25+20+20

If you like this method, you may try it another method is called work Backwards

5x32=160

Then divide 160 by 5 to double check and you get 32!!

========================================

Therefore, the answer s 160 as his total score

hope this gives you a clue to what we are doing and when you have a question like this, I really hope you understand the concept

Hope this helped (:
