jolli1 [7]
You have:
 1)The slant height is:
 Slant height=√[(8 inches)²+(8 inches)²]

A model train is 6 inches the real train is 42 feet what is the scale factor in inches
fredd [130]

1 foot = 12 inches
42 feet = (42 x 12) = 504

The factor of (6 inches / 42 feet) is (6 inches / 504 inches) = 1 / 84 .

The scale factor is not in inches.  It's a factor, and has no units.
A 1-ft model would represent a real 84 feet.
A 1-meter model would represent a real 84 meters.
A 1-yard model would represent a real 84 yards.

The track team is trying to reduce their time for a relay race. First they reduce their time by 1.2 minutes. Then they are able
Digiron [165]

Answer:

5.2 Minutes, or 5 minutes and 12 seconds

Step-by-step explanation:

You can solve this problem by working backward.  Since our number gets smaller by a 1/10 or 0.1, in order to work backward we must multiply 3.60 by 10/9, since one tenth has been taken away already.  When we do this, we get 4.0.  When we add 1.2 minutes to that, we get a final answer of 5.2 minutes, or 5 minutes and 12 seconds.
