On a blueprint, a wall that is 45 feet long is 6 inches long. how long should a girder appear on the blueprint if the girder is actually 30 feet long?

4 inches

Step-by-step explanation:

1 foot = 12 inches

45 feet --- 6 inches

From this we can conclude that the scale of the Blueprint is:

1 foot in actual = 1/90 foot on blueprint

If the girder is actually 30 feet long, then

30 feet --- (1/90*30*12) inches

30 feet --- 4 inches

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
