Answer:

x=9.167

Step-by-step explanation:

12x+240=350

350-240 because you are getting rid of 240 to get 12x by itself so you must do it on the other side.

12x=110, then you do 12x/12 and 110/12

x=9.167

Answer: Approimately $9.16

Step-by-step explanation:

In this problem, you have to solve for x variable.

1. Distribute the 12 to the x + 20 which is 12x + 240

2. Subtract 240 from both sides so 350 - 240 is 110.

3.  Now your equation is 110 = 12x

4. Divide 12 on both sides. But 12 doesn't go into 110 perfectly.

5. 110 divided by 12 is approximately 9.16.

The x represent how much the student has earn extra to get $350 in 12 months. The student has to earn 9.16 dollars every month on top of the 20 dollars.

Answer:

1134.11

Step-by-step explanation:

The problem with this equation is pi is an angle in radians. It has a never ending number of digits.

The area of a circle is basically a square r x r rotated through 180 degrees around the squares centre.

So the area can be written as 180 x 19 x 19 = 64980 degrees meters square.

This is a finite number. The area of a circle does not change. Pi r squared has an ever increasing result.

pi is a conversion factor between the finite areas of circles and the area in square units which can never have a result that is finite as squares cannot fill a circle, no matter how small.

To convert the round finite area to m squared you divide the area by 180/pi = 57.295779513 degrees per radian.

Area in degrees meters Squared 64980/ 57.295779513.

= 1134.1149479 radian meters squared.

Answer:

C is your correct answer : y = 2x + 3

Step-by-step explanation:

Your answer choices are all in slope-intercept form.

Slope-Intercept Form: y=mx+b

First, you need to find the y-intercept.

Coordinate Point: (0,3) is your y-intercept.

Now, you need to find the slope.

This slope is positive.

There's another point (1,5).

This point is important because you can start at your y-intercept and rise and run to get to (1,5).

You have to rise up 2 and go over to the right 1.

2/1 is your slope but simplified is 2.

Your formula: y = 2x + 3

C is your correct answer

[tex]\csc(90^{\circ}-\theta)\\\\=\sec \theta \\\\=\sqrt{10}[/tex]

Answer:
The answer is C. [tex]y = \frac{1}{12}(x+2)^{2}+2[/tex]

Answer:

Option 2: (1, 0) and (0, -5)

Step-by-step explanation:

Let's solve this system of equations using the elimination method.

Start by labelling the two equations.

5x -y= 5 -----(1)

5x² -y= 5 -----(2)

(2) -(1):

5x² -y -(5x -y)= 5 -5

Expand:

5x² -y -5x +y= 0

5x² -5x= 0

Factorise:

5x(x -1)= 0

5x= 0 or x -1= 0

x= 0 or x= 1

Now that we have found the x values, we can substitute them into either equations to solve for y.

Substitute into (1):

5(0) -y= 5 or 5(1) -y= 5

0 -y= 5 or -y= 5 -5

y= -5 or -y= 0

y= 0

Thus, the solutions are (0, -5) and (1, 0).

Answer:

arc UH = 67°

Step-by-step explanation:

the measure of a chord- chord angle is half the sum of the measures of the arcs intercepted by the angle and its vertical angle , then

[tex]\frac{1}{2}[/tex] ( BE + UH ) = ∠ BKE , that is

[tex]\frac{1}{2}[/tex] (119 + UH ) = 93° ( multiply both sides by 2 to clear the fraction )

119° + UH = 186° ( subtract 119° from both sides )

UH = 67°

Answer:

Step-by-step explanation:

∠HKU = ∠BKE   {Vertically opposite angles}

∠HKU = 93°

Angles fromed by insecting chords equals half the sum of intercepting arcs.

      [tex]\sf \angle HKU =\dfrac{1}{2}(arc \ HU + arc \ BE) \\\\ 93^ \circ = \dfrac{1}{2}(arc \ HU + 119)[/tex]

   93 *2 = arc HU + 119

   186    = arc HU + 119

186 - 119 = arc HU

arc HU = 67°

Using proportions, it is found that she will need 12 pints of ice cream.

A proportion is a fraction of a total amount.

Each cup is equivalent to 0.5 pints. There are 24 students, and each student needs a cup, hence 24 cups are needed.

In pints, the equivalent amount is given by:

P = 24 x 0.5 = 12.

Answer:

I believe the answer would be B) x^2 - 16x + 64 = -21 + 64

Step-by-step explanation:

When you're completing the square you take the "middle" term (in this case it's -16) and you divide it by two, then square it. By doing that for this problem you get 64 (16/2 = 8 - 8^2 = 64; signs don't matter in this case because you multiply 2 negatives). You have to add that 64 to BOTH sides so that the equation evens out.

Ultimately, with it factored, the answer will be (x-8)^2

Answer:

Step-by-step explanation:

Using Reflection, ADP and BCP are the same.

If line PD is equal to line PC, angle 1 is equal to angle 2 and angle 3 is equal to angle 4, then line AP is equal and a reflection of line BP, line AD is also equal and a reflection of line BC

In reflected angles, the sides and angles of the shape are not altered.

The original image and reflected shape above are same size and shape therefore triangle ADP and BCP are the same.

The value of the quadratic equation x has a value of 0.8968 and a negative value of 2.23.

It is a method for dividing a polynomial into parts, each of which will be multiplied. At this time, the polynomial's value will be zero.

The equation for the expression is given below.

3x² + 4x = 6

3x² + 4x - 6 = 0

we know that the formula

[tex]\rm x = \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Then we have

General form of an exponential equation: [tex]y=ab^x[/tex]

where:

Let x = years

Let y = investment value

Use (2, 692) and (4, 952) to find a and b of the exponential equation:

[tex]ab^2=692[/tex]

[tex]ab^4=952[/tex]

[tex]\implies \dfrac{ab^4}{ab^2}=\dfrac{952}{692}[/tex]

[tex]\implies b^2=\dfrac{238}{173}[/tex]

[tex]\implies b=\sqrt{\dfrac{238}{173}}=1.17\:\textsf{(nearest hundredth)}[/tex]

[tex]\implies ab^2=a\left(\dfrac{238}{173}\right)=692[/tex]

[tex]\implies a=\left(\dfrac{59858}{119}\right)=503.01\:\textsf{(nearest hundredth)}[/tex]

Therefore, the exponential equation is:

[tex]y=503.01(1.17)^x[/tex]

18 years after the initial investment is when [tex]x=18[/tex]:

[tex]\implies 503.01(1.17)^{18}=8490[/tex]

Therefore, the amount closest to the value of the investment 18 years after the initial investment is $8490

The exponential function that gives the value of the car in t years after 2008 is:

[tex]A(t) = 27500(0.88)^t[/tex].

Using the function, the estimate for the value of the car in 2016 is of $9,900.

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

In this problem:

Hence, the equation is:

[tex]A(t) = 27500(0.88)^t[/tex]

2016 is 8 years after 2008, hence the value of the car will be given by:

[tex]A(8) = 27500(0.88)^8 = 9900[/tex]

The exponential function is given as y = 27500(0.88)ˣ and the value of the car in 2016 is $9890

An equation is an expression that shows the relationship between two or more variables and numbers.

Let y represent the value of the car after x years after 2008, hence:

at x = 0, y = 27500

27500 = ab⁰

a = 27500

At x = 1, y = 24200, hence:

24200 = 27500b¹

b = 0.88

y = 27500(0.88)ˣ

In 2016, x = 8, hence:

y = 27500(0.88)⁸ = 9890
