Answer:
A = 20.5 sq units
Step-by-step explanation:
you have the height of 5 but need to figure out the base
we can use the Pythagorean Theorem two times to find it
1) a² + 5² = 7²
a² = 49-25
a = 
= 
·
= 2
2) b² + 5² = 6²
b² = 36-25
b = 
Base = 2 +
A = 1/2 x 5· (2 + )
A = 2.5 · (2 + )
A = 2.5(8.2)
A = 20.5
Answer:
200 kg
Step-by-step explanation:
If w is the amount of water added, then the concentration of the solution is ...
salt/solute = 100(0.30)/(100 +w) = 0.10
30 = 10 +0.10w . . . . . simplify
20 = 0.10w . . . . . . . . subtract 10
20/0.10 = w = 200 . . . . divide by 0.10
200 kg of water must be added to dilute the solution to 10%.
The answer is AB= 52, because x=15
