The blueprint for a house has a scale of 1: 5 a wall in the blueprint is 3 inches what is the length of the actual wall

Hello!

The ratio of 1:5

The ratio we are find is 3 : x

We have to find what happened between the ratios

To do this you divide the new number by the old one

3 / 1 = 3

They multiplied the scale by 3 to get the actual wall

Use this to get the length of the wall

3 * 5 = 15

The answer is 15 inches or 1ft 3in

Hope this helps!

Volume of the sphere = (4/3) * 3.14 *  (2.35)^3       [ 2.35 = 1/2 * 4.7 = radius]

total weight = vol * density  = (4/3) * 3.14 * 2.35^3  * 14.25 

                    =  774.26 pounds
