Answer:
2.86 quarts ( approx )
Step-by-step explanation:
Given,
The initial quantity of the Mr. Gittleboro's radiator that contains 30% antifreeze = 10 quarts,
Let x quarts of pure antifreeze replaced x quarts of Mr. Gittleboro's radiator to bring it up to a required 50% antifreeze,
So, the quantity of 30% antifreeze radiator after drained off x quarts = (10-x) quarts
Also, the quantity of final antifreeze radiator 50% antifreeze = 10 quarts
Thus, we can write,
30% of (10-x) + 100% of x = 50% of 10
30(10-x) + 100x = 500
300 - 30x + 100x = 500
300 + 70x = 500
70x = 200
x = 2.85714285714 quarts ≈ 2.86 quarts
Answer:
A
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Here g(x) is the graph of f(x) = x² shifted 4 units to the left, hence
g(x) = (x + 4)² → A
Answer: The empty set
The empty set is a subset for every set.
Answer:
70130000000
Step-by-step explanation:
(Assuming that that 7013 is supposed to be 7013 not 7.013), We will move the decimal place to the right 7 times, since it is 10 to the power of 7. Since the decimal place is at the end of the number, we have to add 7 zeros. This becomes 70130000000.
Its kinda blurry and I can't read the whole question
