The type of limacon graphed is a convex.
8 feet x 10 = 80 feet of pipes. 80 x 12 = 960 inches of pipes.
960 inches of pipes / 18 inch piece = 53 and 6/18 = 53 and 1/3
You can get 53 pieces at 18 inches apiece with 6 inches of pipe left over.
Answer:
l : b = 6 : 5
Step-by-step explanation:
let's assume lenght of each congruent rectangle be x
now,
Lenght of the larger rectangle =
=》3 × lenght of smaller rectangle = 3x
but it is also equal to
=》4 × width of each smaller rectangles ( b )
so, we get :-
=》4 × b = 3x
=》b = 3x / 4
so, we get width of smaller rectangle =

now, width of larger rectangle =
=》lenght of smaller rectangle + (2 × width of smaller rectangle)
=》

=》

=》

=》

now, length of larger rectangle = 3x
width of larger rectangle = 5x/2
so l : w :-
=》

=》

=》

so, required ratio of l : b = 6 : 5
2 irrational numbers between 10 and 11 are:- 10.47277382 and 10.93837389
