For the cost to be the same:
18648+23.5b=83556+10b subtract 10b from both sides
18648+13.5b=83556 subtract 18648 from both sides
13.5b=64908 divide both sides by 13.5
b=4808
So if 4808 books are produced the cost of both methods is the same.
The height of the pyramid is 45 feet.
Using the formula
v= volumn
a= base area
h=height
V=A x h/3
Solving for h
h=3V
A=3X600/40=45ft
To find height, First, square the base area to find the bottom area. Then, divide the known extent by way of the bottom location. finally, multiply the obtained quotient with the height of three to get the pyramid height.
The peak of a rectangular-primarily based pyramid the usage of your expertise of algebra. H = V / (L x W) / three

To nswer this you have to get a scientific calculator and multiply the number in the line of a and b times cos and then divide it for example the line a is 4.24 but when you multiply it by cos it is 0.997263104 and b is 3 but when you multiply by cos its 0.998629534, now divide 0.997263104 by 0.998629534 to get 0.998631694...
Hope this helps
Foil
first
outer
inner
last
example if you had
(x+y)(z+t)
first x times z
outer x time t
inner y times z
last y times t
so
FOIL
(t+2bs^2)(2t-3bs^2)
FIRST (t times 2t=2t^2)
Outer (t times -3bs^2=-3tbs^2)
Inner (2bs^2 times 2t=4tbs^2)
Last (2bs^2 times -3bs^2=-6b^2s^4)
now add
2t^2-3tbs^2+4tbs^2-6b^2s^4
add like terms (-3tbs^2+4tbs^2=1tbs^2=tbs^2)
2t^2+tbs^2-6b^2s^4
