# A phone company chargers each customer a monthly fee of \$10.75. In addition, it charges \$0.03 per minute for in-state calls and \$0.11 per minute for out of-states calls. What is the total monthly charge for customer who made 350 minutes of in-state calls and 95 minutes of out-of-state calls?

\$31.70

Step-by-step explanation:

In order to find the total monthly charge for the customer, you can set up an equation using two different variables and putting in the charges and number of calls for each.

Let 'x' = the number of in-state calls and 'y' = the number of out-of-state calls.

Equation:  0.03x + 0.11y + 10.75 = total

Since the customer made 350 minutes of in-state calls, x = 350 and 95 minutes of out-of-state calls, y = 95:

0.03(350) + 0.11(95) + 10.75 = total

\$10.50 + \$10.45 + \$10.75 = \$31.70

Point F is on circle C. What is the length of line segment GF?
12.5 units
15.0 units
17.5 units
20.0 units

We know that :  GF = GC + CF.Also, CF is a radius. So CF = 7.5 unitsTo find GC we will use the Pythagorean theorem.GC² = 10² + 7.5²GC² = 100 + 56.25GC² = 156.25GC = √ 156.25GC = 12.5GF = 12.5 + 7.5 = 20Answer:  d. 20 units.

20.0 units

Step-by-step explanation:

Line segment CF is congruent to CE, so CF also equals 7.5

Use the pythagoran theorem  to find the measure of GC

Now that  we know GC has a measure of 12.5, we can add it with CF

12.5+7.5= 20.0

How to define a parabola with all its properties -

In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.

The general equation of a parabola is  where x and y are the x and the y intercepts and a is the distance of the focus from the vertex of the parabola.

The latus rectum of parabola is defined as the line segment passing through its focus and perpendicular to its axis.

For the given parabola,

Vertex : (0,0)

Focus : (5/4, 0)

Axes of symmetry : y = 0

Directrix : x = - 5/4

Length of latus rectum : 5 units

Thus the parabola can be formed and so can be plotted in the graph.

Corresponding sides of similar triangles are proportional?

Yes that's right - that means that if you take one triangle and multiply all its sides by the SAME factor, you'll end up with the other triangle. It's the same shape, just a different size.

Solve for x in equation
x-c/2=d

X-c/2 = d
Multiply by 2 on both sides. Leaves us with:
x-c = 2d
Add 2 to both sides. Leaves us with:
x = 2d + c
Unless you have values to substitute into the variables, this is your answer:
x = 2d + c

10 - x = 2(-2x - 4)
Identify with either No Solution or All Real Numbers.

-6 (All Real Numbers)

Step-by-step explanation:

First, you need to solve it and then determine if it is a solution or not. -6 is an integer, making it a real number. Therefore, the answer is "All Real Numbers".

Hope this helps! :-)

Step-by-step explanation:

Isolate x on one side of the equation.

2(-2x-4)  ← (Expand by using with distributive property.)

DISTRIBUTIVE PROPERTY

⇒ A(B+C)=AB+AC

⇒ A(B-C)=AB-AC

A=2

B=(-2x)

C=4

2(-2x)-2*4

-2*2x-2*4

-2*2x-2*4 (Solve.)

-2*2-2*4=-4x-8

Rewrite the equation problem.

10-x=-4x-8

10-x-10=-4x-8-10 (Subtract 10 from both sides.)

Solve.

-x=-4x-18

-x+4x=-4x-18+4x (Then, add 4x from both sides.)

3x=-18 (Solve.)

3x/3=-18/3 (Divide by 3 from both sides.)

-18/3 (Solve & Simplify.)

-18/3=-6

X=-6

Therefore, the correct answer is x=-6.
