Answer:
1. 2 eggs 2. 53 mph 3. $8 per hour 4. 1 gal per hour
Step-by-step explanation:
1. There are 4 eggs used in 2 batches. For one batch, you divide 4 eggs by 2 batches to get 2 eggs for each batch.
2. There are 265 miles in total, so to get the average speed each hour, you divide the total by 5 hours to get 53 miles per hour.
3. In 7 hours, he got $56. Divide 56 by 7 to get the pay each hour, which would be $8 per hour.
4. In a half hour, the swimming pool has leaked a certain amount of water. Double that to get how many gallons per hour. gallons per hour.

Answer:
is standard equation of hyperbola with vertices at (0, ±9) and foci at (0, ±11).
Step-by-step explanation:
We have given the vertices at (0, ±9) and foci at (0, ±11).
Let (0,±a) = (0,±9) and (0,±c) = (0,±11)
The standard equation of parabola is:
From statement, a = 9
c² = a²+b²
(11)² = (9)²+b²
121-81 = b²
40 = b²
Putting the value of a² and b² in standard equation of parabola, we have
which is the answer.
