52. How many four-letter "words" can be made from 6 letters "AEBWDP" if a. repetition of letters is allowed
b. repetition of letters is not allowed

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )

its very big question plz make it small

answer: given the scale 3,5 mm to 1 foot: so you know this and you need convert this 150mm to get the right answer.
