Answer: 1590.63\ ft^2

Step-by-step explanation:

Given

The sprinkler can water the area up to 30\ ft  i.e. 30\ ft  is the radius

If the screw leads to a reduction of 25% in radius, then the new radius is

r'=(1-0.25)r\\r'=0.75r\\r'=22.5\ ft

So, the area corresponding to this radius

\Rightarrow \pi (22.5)^2\\\Rightarrow 1590.63\ ft^2

Thus, the maximum area that can be covered is 1590.63\ ft^2

<h3>What are ratio and proportion?</h3>

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

A kicker made 10 of his last 12 field goals.

Predict the number of his next 42 field goals the kicker will not make will be

Let x be the number of his next 42 field goals the kicker will not make.

Then we have

x / 10 ≠ 42 / 12

      x ≠ 35

More about the ratio and the proportion link is given below.

Find the solution to the given equation if the replacement set is {6, 9,15,16}.
Alexxandr [17]
They gave you a set of numbers that you replace the variable x in the equation to see if it gives a correct answer so just do exactly that.

6 + 2x = 24
6 + 2(6) = 24
6 + 12 = 24
18 = 24      so incorrect. both sides are not equal to each other.

6 + 2x = 24
6 + 2(9) = 24
6 + 18 = 24
24 = 24       so correct. both sides are equal to each other.

6 + 2x = 24
6 + 2(15) = 24
6 + 30 = 24
36 = 24       so incorrect. both sides are not equal to each other.

6 + 2x = 24
6 + 2(16) = 24
6 + 32 = 24
38 = 24      so incorrect. both sides are not equal to each other.

so your answer is b) 9

hope this helps, God bless!
