playground to another drawing is 3 ft to 1 cm. What are the side lengths of the playground in the other scale drawing?

Answer: for plato users

A is the correct answer

Step-by-step explanation:

I just took the test had 100%

The correct option is A. [tex]x^{2} -x-10=0[/tex].

Given quadratic equation  [tex]\frac{2}{3x-6} -\frac{1}{3x+6} =\frac{1}{3}[/tex]

On solving,  [tex]\frac{2(3x+6)-1(3x-6)}{(3x-6)(3x+6)} =\frac{1}{3}[/tex]

Further, [tex]\frac{6x+12-3x+6}{9x^{2} -6^{2} } =\frac{1}{3}[/tex]

[tex]\frac{3x+18}{9x^{2} -36} =\frac{1}{3}[/tex]

Taking 3 common from numerator and 9 common from denominator, we have

[tex]\frac{3(x+6)}{9(x^{2} -4)} =\frac{1}{3}[/tex]

[tex]\frac{(x+6)}{3(x^{2} -4)} =\frac{1}{3}[/tex]

[tex]\frac{x+6}{x^{2} -4} =1[/tex]

[tex]x+6=x^{2} -4[/tex]

On rearranging in decreasing powers of x we get,[tex]x^{2} -x-10=0[/tex].

Hence on solving, We get [tex]x^{2} -x-10=0.[/tex]

Answer:

y=1/3x +16/3

Step-by-step explanation:

m=(y2-y1) / (x2-x1)

   =(6-5) (2- -1)

    =1/3

Substitute in m and either point into the point slope form

y=m(x-x1) + y

y=1/3(x- -1) +5

y=1/3(x+1) +5

Now lets distribute the 1/3 to and combine the constants to put the answer in standard form

y=1/3x + 1/3 + 5

y=1/3x +1/3 + 15/3

y=1/3x +16/3

Step-by-step explanation:

The data provided in the table does not represent a linear pattern option (b) No, it does not appear on a straight line correct.

It is defined as the change in values of a dependent variable with respect to the independent variables.

It is given that:

Four years ago, you invested $1000 in an account that returns 5.1% annually.

The table represents the value of your investment at the end of each year.

Time (in years)            Value (in dollars)

          1                                    $1051.00

          2                                    $1104.60

          3                                    $1160.94

          4                                    $1220.14

Plot the point (x, y) on the coordinate plane:

From the graph, as we can see (1,  $1051.00) does not lie on the line.

Thus, the data provided in the table does not represent a linear pattern option (b) No, it does not appear on a straight line correct.

Answer:

Length in feet:  x-70

Step-by-step explanation:

Use factorization to find the length

Area = X^2-120x+3500

Area= length x width.

Area= L x (x-50)= (x-___) (x-50)

To find L we know that in factoring the quadratic equation 50 x __ must be equal to 3500.

(x-70)(x-50) = x^2-120x+3500.

Answer:

Geometric figure: Straight Line

Slope = 120.000/2.000 = 60.000

x-intercept = 346/-60 = 173/-30 = -5.76667

y-intercept = 346/1 = 346.00000

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

y-(-4+60*x+350)=0

Equation of a Straight Line

1.1 Solve y-60x-346 = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-60x-346 = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 346/1 so this line "cuts" the y axis at y=346.00000

y-intercept = 346/1 = 346.00000

Calculate the X-Intercept :

When y = 0 the value of x is 173/-30 Our line therefore "cuts" the x axis at x=-5.76667

x-intercept = 346/-60 = 173/-30 = -5.76667

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 346.000 and for x=2.000, the value of y is 466.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 466.000 - 346.000 = 120.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = 120.000/2.000 = 60.000

Geometric figure: Straight Line

Slope = 120.000/2.000 = 60.000

x-intercept = 346/-60 = 173/-30 = -5.76667

y-intercept = 346/1 = 346.00000

Answer:

approx 216

Step-by-step explanation:

well we go to the 10mm mark and we add the columns taht appear before that. Those are two columns : the brown/orangey one and the green one.

if the scale goes up in twenty and each jump has four squares then we can say that one square is equal to 5 up

so we now can read the first two columns

the first one reads 135

the second one reads approximately 81

we add those up and that becomes 216

so the answer is approximately 216

Answer:

Step-by-step explanation:

a. Gradient of A = 7/-7 = -1.

b. For line B, m = 3/1.5 = 2 and c = y-intercept = 3.

c. The line parallel to B will have the same gradient m = 2.

It also passes through (1, -1) so we use the point-slope form of the straight line

y - y1 = m(x - x1)

Here m = 2 and (x1, y1) = (1, -1) so

y - (-1) = 2(x - 1)

y = 2x - 2 - 1

y = 2x -3.
