Answer:
Step-by-step explanation:
Let the age of Seema be x and her father be 3x
After 12 years,
Age of Seema=x+12
Age of father=3x+12
Now we have,
Again,
Present age of her father=3x=3×12=36
Hence, the present age of Seema is 12 and her father is 36.
Answer:
2 candies were left.
Step-by-step explanation:
Number of bags of candies = 4 bags
Number of candies in each bag = 18 candies
Total number of candies =
Ms. Rogers put an equal number of these candies into each of 7 gift boxes.
Divide 72 by 7
72 = 7(10) + 2
Here, remainder is 2.
So,
2 candies were left.
we know that
The equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex
if -----> then the parabola open upward (the vertex is a minimum)
if -----> then the parabola open downward (the vertex is a maximum)
The axis of symmetry is equal to
In this problem let's analyze two cases
First case
the vertex is the point
so
-----> then the parabola open upward (the vertex is a minimum)
The axis of symmetry is equal to
Second case
the vertex is the point
so
-----> then the parabola open upward (the vertex is a minimum)
The axis of symmetry is equal to
