Answer:
AREA = 4,850
Step-by-step explanation:
split into two pieces
formula for triangles- base x height divided by 2
20 x 50 = 100 / 2 = 50
(130 - 50 = 80)
80 x 120 = 9,600 / 2 = 4,800
add...
4,800 + 50 = 4,850
Last option is the correct answer.
Step-by-step explanation:
Given that
Let x stand for the solution a and y stand for the solution B
So,
According to statement that
30 gallons have to be made
Solution A contains 29 percent bromine => 0.29x
Solution B contains 53 percent =>0.53y
And the mixture of 30 gallons contains 45% bromine
Following equations will be used for solving the problem
Hence,
Last option is the correct answer.
