Answer:

the answer is 23

Step-by-step explanation:

100/50=2

46/2=23

Answer:

23

Step-by-step explanation:

50/x=100/46

(50/x)*x=(100/46)*x       - we multiply both sides of the equation by x

50=2.17391304348*x       - we divide both sides of the equation by (2.17391304348) to get x

50/2.17391304348=x

23=x

x=23

now we have:

Answer:

94

Step-by-step explanation:

the sum of the angles in a triangle add up to equal 180

180-73-13=94

Answer: X = 89°

Step-by-step explanation:

At first glance I could tell this was an isosceles triangle, the angles of an isosceles triangle add up to 180°. So just add 73° + 13° = 91° so then you subtract 91° from 180° and you get 89°.

Answer:

(5,-2)

Step-by-step explanation: the right of the origin is a positive number and below is negative there fore if you go right 5 it would be 5 and down 2 would be -2 .

The ordered pair describes a point that is located 5 units to the right of the origin and 2 units below the x-axis are (5, -2).

A coordinate grid has two perpendicular lines, or axes labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.

Given a statement for coordinates a point that is located 5 units to

the right of the origin and 2 units below the x-axis,

so the left side of the x-axis is the negative value of x and the right side of x-axis is the positive values of x.

5 units to the right, which is the coordinate of x is 5

and the upper of x-axis is the positive side of the y-axis and down of x-axis is the negative side of the y-axis,

2 units below the x-axis, which is coordinate of y is -2

point is (5, -2).

Hence the coordinates of points are (5, -2).

Answer:9

Step-by-step explanation:1/7 of 63 =9

Total amount spend by Jillian for the fabric is $20.7.

Division is a process of splitting a number into two or more equal parts.

Given is that Jillian buys 3.6 meters of fabric. The fabric costs $5.75 for each meter.

Assume that Jillian spend ${x} for the fabric.

Total length of fabric bought by Jillian = 3.6 meters

Cost of 1 m of fabric = $5.75

So, we can write the total cost of fabric as -

x = 3.6 x 5.75

x = 20.7

Therefore, total amount spend by Jillian for the fabric is $20.7.

Remember:

Answer:

(3,-4)

Step-by-step explanation:

You can find the vertex where x = -b/2a

To find the values of a and b, it would be easier to write the equation in standard form, which is y = ax^2 + bx + c

y = 2(x^2 - 6x + 9) - 4

y = 2x^2 - 12x + 18 - 4

y = 2x^2 - 12x + 14

In this equation, a = 2 and b = -12.

So let's plug that into x=-b/2a

x = -(-12)/2(2)

x = 12/4

x = 3

Now we have the x, we can just plug that into the original equation and get the y coordinate for the vertex.

y = 2(x - 3)^2 - 4

y = 2(3 - 3)^2 - 4

y = -4

The equation of directrix of the parabola will be x = -4.

Directrix is a straight line distance to which from any point of a conic section is in fixed ratio to the distance from the same point to a focus. The directrix is perpendicular to the axis of symmetry and does not touch the parabola.

We have,

Vertex of parabola = (0, 0),

Focus of the parabola = (4, 0),

Now,

The Equation of directrix is given by y = -a

Where,

The equation of the parabola, [tex]y^2 = 4ax[/tex],

And,

Focus at (a, 0),

i.e. a = 4    (As the given focus is (4, 0))

And,

The axis of the parabola is the positive x − axis.

So,

The equation of the directrix of this parabola,

x + a = 0,

i.e.

x + 4 = 0

⇒

x = -4

Hence, we can say that the equation of directrix of the parabola will be x = -4.

Answer: $1.38

Step-by-step explanation:

Let the value of the Reese be represented by x

Since the chip cost $1.60 more than the Reese, then the chip will be:

= x + 1.60

Since they cost $4.36 altogether, the value of the Reese will be:

x + (x + 1.60) = 4.36

2x + 1.60 = 4.36

2x = 4.36 - 1.60

2x = 2.76

x = 2.76/2

x = 1.38

The Reese cost $1.38
