1:3

Step-by-step explanation:

Answer:

3:9

1:3

because we know that it is 3:9 So we have to simplify it and then 3 divided by 3 equals 1 so 9 divided by 3 is 3

Answer:

559/250

Step-by-step explanation:

Answer:

223607/100000

Step-by-step explanation:

I'm not sure if this is what you wanted, but 2.23607 is 223607/100000 as a fraction because the decimal is in the 100,000th place. It can't be simplified any more, but if you were to round it would be 559/250. Hope this helps you!

Answer:

A (-7, 1) = (X1, Y1)

B (3, -5) = (X1, Y2)

Now,

Mid point = (X1 + X2÷2, Y1 + Y2 ÷ 2)

= {-7+3÷2, 1+(-5)÷2}

= (-4÷2, 1-5÷2)

= (-4÷2, -4÷2)

= (-2, -2)

Answer:

B

Step-by-step explanation:

Since the y-intercept is (0,3), the second part of the equation of slope (y = mx+b) will be +3. There are three ways to find the slope. Just look at the graph and see how much y increases for every time x increases is the first way. Another way is to find two points that have WHOLE numbers. now count the distance of y between them and the distance of x between them. Now put y over x (y/x). The last way is y1-y2/x1-x2, where you choose to straight points and subtract the y from the other y and the x from the other x, then put y over x. Now we can put the whole equation together to get y = 3/2x +3. or y = 1 and 1/2x+3 (its usually an improper fraction though). Hope this wasn't confusing and helped.

Answer:

I have no idea, I have been trying to figure it out

$93.60 x 0.2 = $18.72

$93.60 + $18.72 = $112.32 = Price before 20% discount.

$112.32 ÷ 100 x 30 = $33. 696 = Discount of 30%

$112.32 - $33.696 = $78.624 = Original Price

Therefore, the store paid $78.624 for the clarinet before the 30% markup and 20% discount.

It's just a process of working backwards.

distributive property

Step-by-step explanation:

5(18)=2(18)+3(18)

Distributive property

c(a+b) = ca+cb

The quotient and remainder, written as partial fractions will be [tex]4x-1 - \frac{2}{x +1} - \frac{3}{(x +2)^2}[/tex].

Quotients are the number that is obtained by dividing one number by another number.

The degree of the numerator is the same as the degree of the denominator, this fraction needs to be simplified.

The rational expression is

[tex]\frac{4x^{3} +11x^{2} -9}{x^{2} +3x+2}[/tex]

Now, the denominator needs to be factored in to split up the second part of the simplified expression into two different partial fractions.

x^2 + 3 x + 2

( x + 1) (x + 2)

The general form of partial fractions.

[tex]A + \frac{B}{x +a} + \frac{C}{(x +a)^2}[/tex]

This gives us,

[tex]4x-1 - \frac{2}{x +1} - \frac{3}{(x +2)^2}[/tex]

Answer:

We have 3 variables to solve for.  We will start by writing two equations in three variables but, with the given information, will eventually have those equations written in 2 variables.  The strategy is to set up equations from the given information and solve the equations simultaneously.  Let's assign variables...

c= #children total

s= #students total

a= #adults total

c+s+a=900.............Eq1, total attendance, given

4c+6s+8a=5600....Eq2, total receipts, given

a=(1/2)(c+s)

 =(1/2)c+(1/2)s.....Eq3, #adults total, given

Let's substitute Eq3 into each Eqs1,2 to get two equations in two variables...

c+s+(½c+½s)=900.........Eq1, substitute for"s"

      1.5c+1.5s=900.......combine like terms

            3c+3s=1800.....Eq4, multiple equation

                                      by 2 to eliminate fraction

4c+6s+8(½c+½s)=5600...Eq2, substitute for "s"

   4c+6s+(4c+4s)=5600...distribute 8

               8c+10s=5600...Eq5, combine like terms

Let's solve newly arrived at Eq4,5 simultaneuously...

    3c+3s=1800......Eq4

  8c+10s=5600......Eq5

-24c-24s=-14400...Eq4 multiplied by (-8)

24c+30s=16800...Eq5 multiplied by 3

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

          6s=2400.....add all terms vertically

        ∴ s=400.......divide both sides by 6

Substitute value back into Eq4, solve for "c"...

      3c+3s=1800...Eq4

3c+3(400)=1800...substitute for"s"

  3c+1200=1800

            3c=600.....subtract 1200, both sides

          ∴ c=200....divide both sides by 3

Substitute values back into Eq3, solve for "a"...

  a=(1/2)(c+s).............Eq3

    =(1/2)(200+400)...substitute for "c,s"

    =(1/2)(600)

∴ a=300.....................simplify

We now have our three variables solved.  Let's substitute those values back into original Eqs1,2 to check against the problem requirements...

          c+s+a=900.......Eq1

200+400+300=900....substitute for "c,s,a"

               900=900......true, √check

                  4c+6s+8a=5600.....Eq2

4(200)+6(400)+8(300)=5600...substitute for

                                                  "c,s,a"

        800+2400+2400=5600...simplify

                         5600=5600......true, √check

So our calculated values are correct. Always check your solutions and work!

In summary, we have...

200 children, 400 students, and 300 adults in attendance at the theater for the screening.

Step-by-step explanation:

There were total 150 childrens, 450 students and 300 adults.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is a theater that has a seating capacity of 900 and charges $2.50 for children, $4 for students, and $5.50 for adults. At a certain screening with full attendance, there were half as many adults as children and students combined. The total money brought in was $3825.

Assume that there were [x] childrens, [y] students and [z] adults. Then, we can write the equations as -

x + y + (1/2)(x + y) = 900

2.5x + 4y + (5.5)(1/2)(x + y) = 3825

Plot the graph. We will get x = 150 and y = 450.

Then -

z = (1/2)(150 + 450) = (1/2)(600) = 300

Therefore, there were total 150 childrens, 450 students and 300 adults.

Answer:

We conclude that:

Step-by-step explanation:

Some background Concepts:

From the graph, it is clear that at x = -10, the graph intersects the x-axis.

So, the x-intercept of the graph is (-10, 0).

It means g(-10) = 0

From the graph, it is clear that at y = 5, the graph intersects the y-axis.

So, the y-intercept of the graph is (0, 5).

It means g(0) = 5

Determining g(-3):

From the graph, it is clear that at x = -3, the value of the function output = 3.5.

In other words,

at x = -3, g(-3) = 3.5

Therefore, we conclude that:

900/100=9

Answer:

9 girls didn't make the team

Step-by-step explanation:

The person above did it a great way, and that is the way I use it, but if you want a method that involves fractions here it is: 20% is the same as 1/5. Since there are 45 girls total, we need to find 1/5 of 45 and you can achieve that by multiplying 45 by 1/5 and you get 45/5 which is 9. Hope this helped :) .

Answer:

y - 5 = x + 4

Step-by-step explanation:

Use point slope form, y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line

Plug in the given point and slope:

y - y1 = m(x - x1)

y - 5 = 1(x + 4)

Simplify:

y - 5 = x + 4

So, the point slope form of the line is y - 5 = x + 4
