(x-73) + (x-65) = x

2x - 138 = x

2x - x = 138

x = $138 cost of the bike

That's a question about percentage.

Let's imagine that we want to know how much is 90% of 200. To do this calculation, we should multiply 200 by 90 and then divide the result by 100. We do that because 90% is the same thing that \frac{90}{100} =0,9. So, 90% of 200 is equal to:

\frac{200\cdot90}{100} =\\\\\frac{18000}{100} =\\\\180

Now, imagine that you would like to know how much is 100% of 999. First, we multiply 999 by 100 and divide the result by 999. So, 100% of a number is equal to itself. That's a very important information, because it's possible to understand this:

  • If the percentage is less than 100%, the result is less than original number.
  • If the percentage is equal to 100%, the result is equal to the original number.
  • If the percentage is greater than 100%, the result is greater than original number.

Now, we can solve our problem! \o/

The options that the percentage is less than 100% are: 35% of 300, 62% of 182 and 89% of 525. Therefore, their answers will be less than the original number.

And, the option that the percentage is greater than 100% are: 250% of 18, 300% of 250 and 120% of 72. So, their answers will be greater than the original number.

On the image, you can see the answer in a table.

I hope I've helped. ^^

Enjoy your studies! \o/

A plane is flying at an altitude of 25,000 m. From the pilot, the angle of depression to the airport tower is 30°. How far is th
maria [59]
The question is modelled as shown in the diagram below

We have the angle, 30° and we know the length of the side opposite the angles, 25000 feet. We are looking for the ground distance between the plane and the tower. We will use the trigonometry ratio of Tan

tan(x)= \frac{opposite}{adjacent}
tan(30)= \frac{25000}{y}
y= \frac{25000}{tan(30)}
y=43301.27019

The distance between the point directly beneath the plane and the tower is 43301.3 feet (rounded to  2dp)
