A micro-photograph of a human hair shows the hair magnified 150 times. If the hair is
stepan [7]

Answer:

<em>The actual width of the hair is 20 / 150 = 0.13 mm</em>

Step-by-step explanation:

<u>Scaling</u>

Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. We use scaling in several applications of real-life.

The human hair is magnified 150 times by a micro-phtograph. This is the scale factor.

The hair can be seen 2 cm wide in the photograph.

Converting to millimeters, 2 cm = 2*10 = 20 millimeters.

The actual width of the hair is 20 / 150 = 0.13 mm

PLZ help Asap!!!!!!!!!!!!!!!!!!!!!!!
maria [59]
I'm may not be that good at math, but I'm going to try my best to help you, because I know how it feels to be in this situation! 

The first one : 
You might be right on D. But I'm thinking B also. The question asks "Which could be a cross section of a rectangular pyramid that has been intersected by a plane perpendicular".  But a triangle is basically a flat pyramid. 

(I'm typing really fast to help!!!!) 

Second one: Its B!! Look at it really closely! You'll get it!!!

(Going really fast now!!!!) 

Third one: Between B or D!!! But I think you're right on your choice!!!!

(FASTER FASTER!!!) 

FINALLY: Copy and paste your answers into google. People have asked the same question! 

I hope I helped. I don't want to make you fail, as I am in the SAME similar situation as you! I really REALLY REALLY HOPE YOU PASS!!!
