A straight line is 180°. 180°-135°=55°, so x=55°, which is an acute angle because it is less than 90°.

Safety regulations require that the time between airplane takeoffs (on the same runway) will be at least 2 minutes. When taking
Xelga [282]

Answer:

1 plane

Step-by-step explanation:

Let's suppose the number of planes waiting or on the runway " P "

the number of planes taking off per hour ' P_{takeoff}'

the time for waiting and the runway T_{wr} so:

P = P_{takeoff}   x T_{wr}

P_{takeoff} = 18 airplanes per hour

we know that 1 min = 60s

36s = 36/60 = 0.6 min

Also, 3 min and 30 s = 3 + 30/60 = 3.5 min

Next to find the time for waiting and the runway

∴T_{wr}= 0.6 + 3.5  = 4.1 min/60 (converting into hour)

T_{wr}= 0.068 hour

P = 18x0.068 = 1.23

therefore, there is 1 plane either on the runway or waiting to take off

So, there is 1 plane either on the runway or waiting to take off

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).
