Answer:

letters

Step-by-step explanation:

The right answer is letters

Arithmetic is a branch of mathematics that studies the numbers and the properties with them. The main properties are addition, subtraction, multiplication and division. Variables are non-constant values, so we use letters to assign a number to a variable and the operator that allows us to do this is =. For instance, if we have the variable x, we can say that this variable is equal to 4. Then:

x=4

Suppose the value of the variable changes to 5, then the new value of it is given by:

x=5

Gemiola [76]

Answer:

the answer should be 1/11

Step-by-step explanation:

p(blue first) = 3/12

p(yellow second) = 4/11

so p = 3/12 x 4/11

1/11 is your probability

In the diagram A, B, and C are the points on the circle. Use the diagram to prove the theorem which states that:
nevsk [136]

9514 1404 393

Explanation:

Here's one way to go at it.

Draw segments AB and CO. Define angles as follows. (The triangles with sides that are radii are all isosceles, so their base angles are congruent.)

  x = angle OAB = angle OBA

  y = angle OAC = angle OCA

  z = angle OBC = angle OCB

Consider the angles at each of the points A, B, C.

At A, we have ...

  angle CAB = x + y

At B, we have ...

  angle CBA = x + z

At C, we have ...

  angle ACB = y + z

The sum of the angles of triangle ABC is 180°, as is the sum of angles in triangle ABO. This gives ...

  x + x + ∠AOB = (x+y) +(x+z) +(y+z)

  ∠AOB = 2(y+z) = 2∠ACB

This shows ∠AOB = 2×∠C, as required.

Two complementary angles are in the ratio 7:8. What is the measure of the larger angle?
yan [13]

Answer

<h3>48°</h3>

Step-by-step explanation:

We know that sum of complementary angle adds to 90°

Let the angles be 7x and 8x

<u>First </u><u>of </u><u>all,</u><u> </u><u>finding </u><u>the </u><u>value </u><u>of </u><u>x</u>

\sf{7x + 8x = 90 °}

Collect like terms

⇒\sf{15x = 90 °}

Divide both sides of the equation by 15

⇒\sf{ \frac{15x}{15}  =  \frac{90}{15} }

Calculate

⇒\sf{x = 6 °}

The value of X is 6°

<u>Now,</u><u> </u><u>substituting </u><u>/</u><u> </u><u>Replacing</u><u> </u><u>the </u><u>value </u><u>of </u><u>x</u>

⇒\sf{7x = 7 \times  6 = 42}

⇒\sf{8x = 8 \times 6 = 48}

The measure of larger angle is 48°

Hope I helped!

Best regards!!
