First off, "whatever%" of "anything" is just (whatever/100) * anything
part A)
so... firm A got 11,000 invested, turned a profit of 24%, how much is 24% of 11000? well (24/100) * 11000
firm B got 14,000 invested, and returned 15% in profits, how much is 15% of 14000? (15/100) * 14000
part B)
for the amounts above, we get 2640 and 2100 respectively
so, the total profit "amount" is 2640 + 2100 or 4740
the total investement was 11000+14000 = 25000
if 25000 is the 100%, how much is 4740 in percentage?

solve for "x"

Therefore, the equation of the circle is 
Answer:
5.3
Step-by-step explanation:
Cos(68) = adjacent/hypotenuse
Cos(68) = 2/AC
AC = 2/cos(68)
AC = 5.3389343253
AC = 5.3
The answer is 87
For this problem, the method I used was more of a guess and check because I simply plugged the options into a calculator to see which one would be closest a little bit past 9.3 but not all the way 9.4
the square root of 87 is 9.32 so you would round down while the square root of 88 is 9.38 which would round up
Hope this helps :)
