The population of a small town is 39,668 and has been continuously declining at a 1.5% a year what will the population be in 13
anyanavicka [17]

Answer:  31, 932.74

Step-by-step explanation:

The population of the small town              =  39,668

Yearly rate of decline                                 = 1.5%

Therefore, to calculate 1.5% of 39,668       = 1.5  x 39,668

                                                                         ------------------

                                                                                  100

                                                                      =   595.02

So, the population is declining by 595.02 on yearly basis.

To ascertain what will the population would have declined to in the next 13 years,

We multiply ,                                                = 595.02 x 13

                                                                      =7,735.26

Now population in 13 years                         = 39,668 - 7,735.26

                                                                      = 31,932.74

Answer:

Water (one oxygen atom bonded to two hydrogen atoms)

Step-by-step explanation:

The chemical formula for water is H²O. The H is the chemical symbol for Hydrogen and O is the chemical symbol for Oxygen. The 2 is a subscript which represents how many atoms of a certain element are in a molecule. In this case, the subscript ² comes after H, indicating that there are two Hydrogen atoms inside water. There is no subscript after O, meaning there is only one Oxygen atom. Therefore, there are two Hydrogen atoms and one Oxygen atom that bond to form water. Hope this helps :))

Jasper is twice as old as Simon now. Simon was 1/5 as old as Jasper in 12 years ago. How old is Jasper in 12 years's time?
3241004551 [841]

Answer:

44 years old

Step-by-step explanation:

Let the age of Jasper be j years old now.

<u>Now</u><u>:</u>

Jasper➣ j

Simon ➣ j/2

<u>1</u><u>2</u><u> </u><u>years</u><u> </u><u>ago</u><u>:</u>

Jasper➣ j -12

Simon➣ j/2 -12

Given that Simon's age=⅕(Jasper's age),

j/2 -12= ⅕(j -12)

<em>Multiply</em><em> </em><em>by</em><em> </em><em>5</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>,</em>

2.5j -60= j -12

2.5j -j= 60 -12

<em>Simplify</em><em>:</em>

1.5j= 48

<em>÷</em><em>1.5</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

j= 48 ÷1.5

<em>Simplify:</em>

j= 32

<u>12 years time:</u>

Jasper➣ j +12

Thus, Jasper's age

= 32 +12

= 44

<h3><em><u>Answers With Steps:</u></em></h3><h3>Question 1:</h3>

For the first problem, understand that you are solving for the area of a circle. The equation for the area of a circle is pi r². By using the leash length as the radius (r), you can get the answer. (The leash length is 3 meters long.)

<em>Question 1 Steps:</em>

pi 3² --->  pi * 9 ---> ≈28.27

<em>Question 1 Answer:</em>

It would have about 28.27 meters² of playable space.

<h3>Question 2:</h3>

For the second problem, it would be much the same as to the first question. There is the same objective to find the area of the circle. Along with that, it gives us a length to work with. This time it is the sprinkler's reach, which would be the radius, or "r" in the equation.

<em>Question 2 Steps:</em>

pi 5² ---> pi * 25 ---> ≈78.54

<em>Question 2 Answer:</em>

The sprinkler would have about 78.54 feet² of space that it can reach.
