Carlos made a scale model of a local bridge. The model spans 6 inches; the actual bridge spans

50 feet

Carlo's scaled bridge model spans 6 inch.

Actual bridge spans  50 feet.

We know that,

1 feet = 12 inches.

i.e  =

actual bridge span = 600 inches.

Scale factor of the model is,

=

That means the scale model is 0.01 time smaller than actual model.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
