Answer:
25.38
Step-by-step explanation:
Its a 3-D block, so you have to find the distance from on corner to the opposite corner of the roof, but first find the distance from corner to corner on the floor.
20^2+12^2=c^2
400+144=544=c^2
c=
then find corner of floor to opposite roof corner.
100+544=644=c^2
c=
so its about 25.38 feet
The answer is 18+(-20) because if if you were going to solve that equation you would use the absolute value of -20 and then the opposite of the sign giving you 18-20. Hope this helps:)
$8622.70 or $10,000 if you are actually estimating.
Judi's share was (7 x $2.50) = $17.50 .
That was really one share out of eight.
So the total bill was
(8 x $17.50) = $140.00 .
ABC ~ A’B’C’
So, AB=A’B’ , BC=B’C’ , AC = A’C’
Given, AB=15 and A’C’=4
So, AC = 4 , A’B’ = 15
