Which of the following inequalities is correct? -5 > 0 -2 > -5 -5 < -8 10 < -13
kotykmax [81]

Answer:

-2 > -5

Step-by-step explanation:

It is easy to answer this question by visualizing the given values on the number line. Recall that when comparing numbers on the number line, the number on the left is smaller than any number to the right of it, and a number located to the right of another number is the larger one.

The disposition of the numbers given to you (from left to right) should appear like:

-13      -8     -5     -2     0            10

Therefore, the only true statement is the second one, which says that -2 is larger than (>) -5. Notice that in fact, -2 is located on the number line to the right of -5, therefore it is larger (>) than -5

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area f
myrzilka [38]

Answer:

The sprinkler can spread water 18 feet away.

Step-by-step explanation:

We are given the following in the question:

Area formed by watering pattern = 1,017.36 square feet

We have to find the how far the sprinkler spread the water.

The sprinkler covers a circular area. We need to find the radius of this circular area to find the how far the sprinkler spread the water.

Area of circle =

A = \pi r^2

where r is the radius of the circle.

Putting values, we get,

1017.36 = 3.14 r^2\\\\r^2 = \dfrac{1017.36}{3.14}\\\\r^2 = 324\\r = \sqrt{324} = 18\text{ feet}

Thus, the sprinkler can spread water 18 feet away.
