The answer is 46 boys
98 minus 6 is 92
92 divided by 2 is 46
Answer:
1/8
Step-by-step explanation:
20 + 10 + 25 + 15 + 10 = 80
10 / 80 = 1/8
First, let x be the amount of 20% acid solution in liters. With this, 60 - x is the amount of 50% solution. The acid balance before and after mixing becomes,
(0.2)(x) + (0.5)(60 - x) = (0.40)(60)
The value of x is 20. Therefore, Gabe needs 20 liters of 20% acid solution and 40 liters of 50% acid solution.
Answer:
Vertex = (7,5)
Length of latus rectum = 2 units
Step-by-step explanation:
The vertex form of a parabola is
...(1)
where, (h,k) is vertex and length of latus rectum is .
The given equation is
...(2)
On comparing (1) and (2), we get
So, vertex of parabola is (7,5).
Length of latus rectum is
Therefore, the length of the latus rectum is 2 units.
