Answer:

$\frac{3}{500}$

Step-by-step explanation:

Start by converting 5 meters to centimeters. Note 1 meter = 100 centimeters.

We can set up a unit converter:

$5m(\frac{100cm}{1m})$

The meters cancel out leaving us with:

$5*100cm=500cm$

The scale factor is:

$\frac{drawing}{real\ life}=\frac{3cm}{500cm}=\frac{3}{500}$

Write the formula to find the profit %, if selling price and cost price both are given.

jolli1 [7]

Answer:

$profit \: percent = \frac{sp - cp}{cp} \times 100 \: percent$

where,

SP=Selling price

CP=Cost price

<h3>For example:</h3>

Given,

Selling price(SP)= 1000

Cost price(CP)=800

Now,

$profit \: percent = \frac{sp - cp}{cp} \times 100 \: percent \\ = \frac{1000 - 800}{800} \times 100 \\ = \frac{200}{800} \times 100 \\ = 25 \: percent$

Hope this helps...

Good luck on your assignment..

Step-by-step explanation:

The second one is the first claim, because it is a traingles and one square.

The third one is the sond claim because they are a part of the rectangular so moving them outside of it would increase the area, I think, if that makes sense.
