Your friend rolls a number cube 500 times. How many times do you think your friend will roll an odd number? Explain your reasoni
VladimirAG [237]
250, because of probability. Half of the number are full of odd numbers. Half are full of even. The probability will be 1/2. So 1/2 of 500 is 250. So your answer is 250 times.

Ab=6cm Ac=12 calculate the lenght of cd
Alchen [17]

This problem involves the uses of the Pythagorean Theorem as well as the use of Sine.

To start we need to identify what we know and what we don't know. We know that there are two triangles. We are given 2 sides lengths and an angle in one and only an angle in the other. They share one side meaning when we are given 2 sides in one triangle it will be easy to get the third side. What we don't know is the side length of CB DB or CD. We need to find CB in order to find CD.

<em>Pythagorean Theorem for side length CB:</em>

12^2-6^2=√108

√108=10.4 (average)

So CB is equal to 10.4

<em>Sine Calculation for side length CD:</em>

Since we have angle 56* we will use the length we found which will be the opposite side from the angle and then input x for our hypotenuse CD in order to solve.

sin 56* = 10.4/x

sin 56* × x = 10.4/x × x

sin 56*x = 10.4

/sin 56*      /sin 56*

x = 12.544....

or 12.6 (average)

So, to conclude, our answer for CD is 12.6cm.

Hope I helped!

Consider the equation 2/3x-9-2x+2=1.
bogdanovich [222]

The one is the same everywhere so we ignore it.


\frac 2 {3} x -9 -2x+2  = (\frac 2 3 - \frac 6 3) x - 9+2= -\frac 4  3 x -7

10 divided by 3 long division
sesenic [268]

Okay so the first thing we need to do is clarify the terms so that you know what each part of the division is:

  • The first number, 10, is called the dividend.
  • The second number, 3 is called the divisor.

What we'll do here is break down each step of the long division process for 10 divided by 3 and explain each of them so you understand exactly what is going on.

<h2>10 divided by 3 step-by-step guide</h2><h3>Step 1</h3>

The first step is to set up our division problem with the divisor on the left side and the dividend on the right side, like we have it below:

  __

3| 10

<h3>Step 2</h3>

We can work out that the divisor (3) goes into the first digit of the dividend (1), 0 time(s). Now we know that, we can put 0 at the top:

   _0_

3 | 10

<h3>Step 3</h3>

If we multiply the divisor by the result in the previous step (3 x 0 = 0), we can now add that answer below the dividend:

 _0_

3 | 10

    0

<h3>Step 4</h3>

Next, we will subtract the result from the previous step from the second digit of the dividend (1 - 0 = 1) and write that answer below:

 ___

3 | 10

- 0

__

1

<h3>Step 5</h3>

Move the second digit of the dividend (0) down like so:

 __0_

3 | 10

 - 0

-----------

10

<h3>Step 6</h3>

The divisor (3) goes into the bottom number (10), 3 time(s), so we can put 3 on top:

 __03_

3 | 10

- 0

___

10

<h3>Step 7</h3>

If we multiply the divisor by the result in the previous step (3 x 3 = 9), we can now add that answer below the dividend:

 _03_

3 | 10

- 0

__

10

 9

<h3>Step 8</h3>

Next, we will subtract the result from the previous step from the third digit of the dividend (10 - 9 = 1) and write that answer below:

  __03_

3 | 10

- 0

__

10

-9

_

1

<h3>So, what is the answer to 10 divided by 3?</h3>

Your answer is the top number, and any remainder will be the bottom number. So, for 10 divided by 3, the final solution is:

<h2>3 </h2><h2> - Remainder 1</h2><h2>Extra calculations for you:</h2>
  • Using a calculator, if you typed in 10 divided by 3, you'd get 3.3333.
  • You could also express 10/3 as a mixed fraction: 3 1/3
  • If you look at the mixed fraction 3 1/3, you'll see that the numerator is the same as the remainder (1), the denominator is our original divisor (3), and the whole number is our final answer (3).
