Answer:

35 students

Step-by-step explanation:

Find 25% of 500:

  1. \frac{25}{100} × \frac{500}{1} = \frac{12500}{100}  
  2. \frac{12500}{100} = \frac{125}{1} = 125  

Find 18% of 500:

  1. \frac{18}{100} × \frac{500}{1} = \frac{9000}{100}  
  2. \frac{9000}{100} = \frac{90}{1} = 90  

Find the difference:

  1. 125 - 90 = 35

So, 35 more students prefer video games to bike riding.

I hope this helps!

Answer:

see explanation

Step-by-step explanation:

Note that cos315° = cos45° and sin315° = - sin45° and

cos45° = sin45° = \frac{1}{\sqrt{2} } = \frac{\sqrt{2} }{2}

Hence

12(cos315° + isin315°)

= 12(cos45° - isin45°)

= 12(\frac{\sqrt{2} }{2} - i \frac{\sqrt{2} }{2})

= 6\sqrt{2} - 6i \sqrt{2}

ii. A machine is sold for 7,000/-. The gross loss is 20% of the cost. What are the cost and gross loss?
aleksley [76]

Given:

Selling price of a machine = 7000/-

Gross loss = 20%.

To find:

The cost and gross loss.

Solution:

Let x be the cost of machine.

According to the question,

x-20\%\text{ of }x=7000

x-\dfrac{20}{100}x=7000

x-0.2x=7000

0.8x=7000

Divide both sides by 0.8.

x=\dfrac{7000}{0.8}

x=8750

So, the cost of the machine is 8750/-.

Now,

\text{Gross Loss}=\text{Cost}-\text{Selling price}

\text{Gross Loss}=8750-7000

\text{Gross Loss}=1750

Therefore, the gross loss is 1750/-.
