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.

Well, first, the equation that you are looking for is Y = MX + B. To find B, look at the first dot on the Y-axis. It starts at positive 3, so, you know your equation will end with +3. Next, to find MX, start at the either dot, and find the Rise/Run. In this particular equation, the rise is 1, and, the run is -2, because it's going backwards (negative line). Meaning, the line's equation would be, f( x )= -1/2x + 3.

The distance from E to side AD is 25/13.

<h3>What is a distance?</h3>

The length of the line connecting two places is the distance between them.
If the two points are on the same horizontal or vertical line, the distance can be calculated by subtracting the non-identical values.

To find what is the distance from E to side AD:

If you draw a diagram, you'll see that triangle AEB is a right triangle with lengths 5, 12, and 13.
Let's call F the point where E meets side AD, so the problem is to find the length of EF.
By Angle-Angle Similarity, triangle AFE is similar to triangle BEA. (the right angles are congruent, and both angle FAE and ABE are complementary to angle BAE)
Since they're similar, the ratios of their side lengths are the same.
EF/EA = EA/AB (they're corresponding side lengths of similar triangles).

Substitute them with known lengths:

EF/5 = 5/13
EF = 5 × (5/13) = 25/13

Therefore, the distance from E to side AD is 25/13.

The correct answer is given below:
Square ABCD has side lengths of 13 units. Point E lies in the interior of the square such that AE=5 units and BE=12 units. What is the distance from E to side AD? Express your answer as a mixed number.

For the past ten years, Michelle has been tracking the average annual rainfall in Boynton Beach, Florida by recording her data i

Sedbober [7]

Answer:

See explanation

Step-by-step explanation:

The average rainfall when you add all 10 years of rainfall up and divide by 10 is an average of 59.946 inches of rain each year. The equation for the data is y = -0.53x + 64.45, this means that the rainfall is getting less each year at a -0.53 inches of rain each year.

x = year (2004 would be 4, etc)
