Usually if it's an basic good, or very important one.
because the price fluctuations do not affect the quantity sold.
a good example of that would be milk, if the milk gallon is say $8, and a family needs 1 gallon daily, they buy it for $8.
if the price drops to $7, they might buy 2, but they only need 1 everyday, just in case they may get another.
if the price drops to $4 or even $3, they're not going to get 10 gallons, there's no need for it on an everyday basis, besides is a perishable.
now if the price goes up to $12, they still need it, and will buy it for $12.
This is a simple ratio question, but first you need to find the number of non red marbles uses... call it a
Jar Tank
54 a
----- ----
1 6750
so using your multiplication skills the number of non red marbles is
Non red = 54 x 9750
thene the total number of marbles in the tank is Red + Non Red
hope it helps
Step-by-step explanation:
A=8B
A+B=180
8B+B=180°
9B=180°
B=20°
so
angle A =8×20=160°
angle B= 20°
we know that
the area of the rectangular banner is equal to
where
W is the wide of the banner
h is the height of the banner
in this problem
In the formula of the area solve for h
Substitute the values of W and A
therefore
the answer is
the height of the banner is
