Answer:

Step-by-step explanation:
AD = BD (CD bisects AB means that it divides the line into two equal parts)
So,
AD = BD = AB/2
So,
AD = 3/2
AD = 1.5
<u><em>Now, Finding AC using Pythagorean Theorem:</em></u>

Where c is hypotenuse (AC), a is base (AD) and b is perpendicular (CD)



Taking sqrt on both sides

Answer:
Deal A) 90% Profit ; Deal B) 60% Profit
Step-by-step explanation:
Multiple ways of solving this problem here is one way:
100k-10k = 90k(Revenue) : Then you make this as a percent by 100k then multiply it by 100.
100*((100,000-10,000)/100,000) = 90%
The same is true for the other equation:
100*((50,000-20,000)/50,000) = 60%
The length of the new tank is 5 times bigger than the old one, so 154×5=770. As a result, the capacity of the new tank is 770L. Hope it help!
