There's a relatively easy way to solve problems of this nature. You determine the contribution made if the only contributor is the one that contributes the least.
A chicken has the least number of feet, so 24 chickens will contribute 48 feet.
Now, you consider the change in contribution made by substituting a larger contributor. Each pig that replaces a chicken will add 2 feet to the total.
Consider how many feet need to be added, and thus how many larger contributors are needed. 80 -48 = 32 feet need to be added, so 32/2 = 16 of the animals need to be pigs.
There are 16 pigs and 8 chickens.
Answer:
it goes into 110 about 9 times
Step-by-step explanation:
Law of sines in a triangle with angles A, B, C and sides a,b,c states that
(sin A)/a =(sinB)/b = (sinC)/c
To use the above ratios, you need at least one angle and one side and one of either an angle or a side. So SSS and AAA don't work
