Answer:
40√3
Step-by-step explanation:
(4√2)(5√6) = 40√3
okay so you should know that the formula for a triangle is:
A=1/2×b×h
where b is breadth and h is height
A is area
so they already gave the area which is 16.2 and they already gave a side ( doesn't matter if it's b or h in this question)
so we put these into the equation of the area of a triangle
A=1/2×b×h
16.2=1/2 × 6 × h
then you will solve algebraically to get 5.4cm which is you answer
to check if correct you can always put in all numbers in equation and you should get 16.2cm
In this case it's correct ✌
I think the question is asking for the cost (C) when we already know that the sell price (S) is $24
So C+M=S
C+0.45C=24
1.45C=24
C=16.5516
And the answer is $16 and 55 cents
Suppose you add x liters of pure water to the 10 L of 25% acid solution. The new solution's volume is x + 10 L. Each L of pure water contributes no acid, while the starting solution contains 2.5 L of acid. So in the new solution, you end up with a concentration of (2.5 L)/(x + 10 L), and you want this concentration to be 10%. So we have
and so you would need to add 15 L of pure water to get the desired concentration of acid.
