Answer:

11,143.3

Step-by-step explanation:

Density measures the number of people per unit area

Density = population / area

1,579,000 / 141.7  = 11,143.30

Answer:

Hi how are you doing today Jasmine

Answer:

$900

Step-by-step explanation:

The formula for simple interest is I = PRT where I is the interest earned, P is the principal/amount deposited or borrowed, R = rate as a decimal, and T = time in years

I = PRT

I = (500)(0.04)(20)

I = 400

Add the interest to the principal, and she will have $900 in 20 years.

Answer:

[tex]A=\frac{215*x}{2}-x^2)[/tex]

Step-by-step explanation:

From the question we are told that:

Total length of building side [tex]x=25feet[/tex]

Perimeter of  fence in [tex]P=190feet[/tex]

Generally the perimeter of the display area is given as mathematically given by

[tex]2L+2B=P+x\\2L+2B=190+25[/tex]

Therefore

[tex]2L+2B=215[/tex]

[tex]L+B=\frac{215}{2}[/tex]

[tex]B=\frac{215}{2}-L[/tex]

Generally the Area of the display area A is given as mathematically given by

[tex]Area A=L*B[/tex]

[tex]Area A=L*(\frac{215}{2}-L)[/tex]

[tex]Area A=\frac{215*L}{2}-L^2)[/tex]

Length L in terms of x

[tex]Area A=\frac{215*x}{2}-x^2)[/tex]

Answer:

T₂ = 1.2 s

Step-by-step explanation:

The time period of a simple pendulum is given by :

[tex]T=2\pi \sqrt{\dfrac{L}{g}}[/tex]

Where

L is length of the pendulum

g is acceleration due to gravity

We have,

T₁ = 1.4 s, L₁ = 0.49 m, L₂ = 0.36 m, T₂= ?

[tex]\dfrac{T_1}{T_2}=\sqrt{\dfrac{L_1}{L_2}} \\\\T_2=\dfrac{T_1}{\sqrt{\dfrac{L_1}{L_2}}}\\\\T_2=\dfrac{1.4}{\sqrt{\dfrac{0.49}{0.36}}}\\\\T_2=1.2\ s[/tex]

So, the new time period is equal to 1.2 seconds.

Step-by-step explanation:

The other graphs are functions.

Graph A is a linear function, and C is an Absolute Value Function.

Graph B also seems to be a function.

However- I can only narrow it down to B or C.  I apologize if my answer is not correct.

Answer:

Step-by-step explanation:

When you are taking off percentages from numbers, you first want to make the percent a number. This step is super simple. Just divide the 18 by 100

This gets you 0.18

Now multiply

84 * 0.18 = 15.12

So 15.12 is the discount

Then take 84 and subtract 15.12

84 - 15.12 = 68.88

So 68.88 is the sell price

Answer:144

Step-by-step explanation:

Use a calculator

or 1/2 x 288 =  288/2 = 144

Answer: 144

Step-by-step explanation:

I'm assuming that the "x" in this statement is a multiplication symbol.

Multiplying any number by 1/2 or 0.5 is the same thing as dividing it by 2.

Therfore the answer is 288/2 which is 144.

Answer:

Step-by-step explanation:

Answer:

tan theta = 8/15

Step-by-step explanation:

Sin is equal to opposite over hypotenuse. So it means that the side opposite from theta is 8, and the hypotenuse is 17.

To find the value of the adjacent side from theta, use the Pythagorean Theorem.

a^2 + b^2 = c^2

8^2 + b^2 = 17^2

64 + b^2 = 289

Subtract 64.

b^2 = 225

Take the square root.

b = 15.

So that means:

the side opposite from theta is 8,

the side adjacent from theta is 15,

the hypotenuse is 17.

Now we take tan, opposite over adjacent, and use the values from the triangle.

tan = opposite / adjacent

tan = 8/15.

Answer:

  y = 11.2 in

Step-by-step explanation:

The product of segment lengths to the near and far intersection points of the secant with the circle are the same for all secants from the same external point. Here, there are three, so we have the relations ...

  9×9 = 5(5+y) = x(x+19)

Then the value of y can be found as ...

  81/5 = 5+y

  16.2 -5 = y = 11.2

__

The value of x is a little trickier, as a quadratic is involved.

  81 = x² +19x

  81 + 90.25 = x² +19x +90.25 . . . . complete the square

  171.25 = (x +9.5)²

  x = √171.25 - 9.5 ≈ 3.58625...

__

Additional comment

For the purpose here, the tangent can be considered to be a degenerate case of a secant in which the two points of intersection with the circle are the same point. For the purpose of this calculation, the length of the tangent is squared. (The distance to the points of intersection is the same.)

I find it easier to remember one rule, rather than a separate rule for tangents. With some imagination, the same rule can be applied when the "secants" meet inside the circle. In that case, they are called "chords".

We have shown the value for x because we suspect some versions of this question may ask for x instead of y. (Rounding may be required in that case.)

5. the two bottom angles are the same btw

[tex]2x+2x+x-15=180\\5x-15=180\\5x-15+15=180+15\\5x=195\\5x/5=195/5\\x=39[/tex]

6. straight lines are 180

[tex]3x+17+x-9=180\\4x+8=180\\4x+8-8=180-8\\4x=172\\4x/4=172/4\\x=43[/tex]

7. another 180

[tex]2x-4+3x+5+2x+11=180\\7x-10=180\\7x-10+10=180+10\\7x=190\\7x/7=190/7\\x=27.14\\[/tex]
