Answer:
A B C D is similar to F G H E
Step-by-step explanation:
Here we can see that
A= F= 110 degrees
B = G= 70 degrees
C= H = 110 degrees
D= E = 70 degrees
Therefore
A B C D is similar to F G H E
so the option 3rd correct.
Answer:
5.714 liters of the 5% solution and 4.286 of the 40%.
Step-by-step explanation:
Let x be the volume of 40% solution and y = volume of the 5% solution.
x + y = 10
0.40x + 0.05y = 0.20(x + y)
From the first equation x = 10 -y so we have:
0.40(10 - y) + 0.05y = 0.20( 10 - y + y)
4 - 0.40y + 0.05y = 2
-0.35y = -2
y = 5.714 liters of the 5%.
and x = 10 - 5.714 = 4.286 liters of the 40% solution.
Step-by-step explanation:
The answer is C 84. Your welcome
