Answer:

Step-by-step explanation:

1). Let the circumference C and area A of the circle are proportional,

   C ∝ A

   C = kA

   Here k = proportionality constant

   k = [tex]\frac{C}{A}[/tex]

   From the given table,

   For C = 25 cm, A = 50 cm²

   Then the value of k = [tex]\frac{25}{50}[/tex]

                                  k = [tex]\frac{1}{2}[/tex]

    For C = 50 cm, A = 201 cm²

    k = [tex]\frac{50}{201}[/tex] ≈ [tex]\frac{1}{4}[/tex]

    In both the cases proportionality constant is giving the different values.

    Therefore, Circumference and Area of the circular objects are not proportional.

2). If A = [tex]\frac{1}{2}\times r\times C[/tex]

    Then this equation will be true for all the values of r and C given in the table.

    For r = 4 cm and C = 25 cm

    A = [tex]\frac{1}{2}\times 4\times 25[/tex] = 50 cm²

    For r = 8 cm and C = 50 cm

    A = [tex]\frac{1}{2}\times 8\times 50[/tex]

    A = 200 cm²

    True for all values of 'r' and 'C'.

Which ordered pair is a solution of the equation y = 10x?

A. (−6, −60)
B. (8, 90)
C. (8, 70)
D. (−10, −80)

Answers

A is a solution.
Basically, you have to plug in your coordinate to the equation. Plug in -60 for y and -6 for x. Now it should look like:
-60 = 10(-6)
Multiply 10 by -6 to get:
-60 = -60
That is a true statement because -60 equals -60. So, A is a solution to the equation. Hope this helped!

If the ratio of the two sides of the triangles are the same then the third sides of the triangle will be parallel. Then the correct figure is D.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

If the ratio of the two sides of the triangles are the same then the third sides of the triangle will be parallel.

⇒ 5.5/15 = 6.6/18

⇒ 0.366 = 0.366

Then the correct figure is D.

A total of 714 tickets were sold for the school play. They were either adult tickets or student tickets. There were 64 more
student tickets sold than adult tickets. How many adult tickets were sold?

Answers

Answer:

714 is the total number that is sold, if there is 64 more tickets sold for students then adults, then do 714 divided by 2 and add 32 to get the number for students, and for adults do 714 divided by 2 and subtract by 32. so, like this 714/2+32=389 tickets for students and 714/2-32=325 for adults. Hope this helps

Answer:

The adult tickets total were 293

Step-by-step explanation:

714 divided by 2 ( because there is only 2 types of tickets )  and 714 divided by 2 equals 357 ad because the student tickets sold better 357 minus 64 = 293 and you prove that by multyplying 357 x 2 = 714

Solve the equation:

7x − 2 = 26

Answers

Answer:

[tex] \large \boxed{x = 4}[/tex]

Step-by-step explanation:

Goal

Solve for x-term.

Given

Equation

[tex]7x - 2 = 26[/tex]

Step 1

Isolate x by adding 2 to both sides.

[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]

Step 2 (Optional)

We check the answer by substituting x = 4 in the equation.

[tex]7x - 2 = 26 \\ 7(4) - 2 = 26 \\ 28 - 2 = 26 \\ 26 = 26[/tex]

The equation is true for x = 4. Hence, the solution is x = 4.
