Answer:
r = 12 ft
Step-by-step explanation:
Pi x r^2 = 450 ft^2
r^2 = 450/pi
r^2 = 143
r = sqrt 143
r = 12
You would take 1818÷33=55.09
55.09 is how many toothpicks it took for each step made
Then you would take 55.09×55=3029.95
You can make sure this is correct by taking 55.09×33=1817.97 which would actually be 1818 because you had to round it up
Answer:
The equation of the axis of symmetry is equal to
Step-by-step explanation:
we have
This is the equation of a vertical parabola written in vertex form open upward (because the leading coefficient is positive)
The vertex represent a minimum
The axis of symmetry is equal to the x-coordinate of the vertex
we have that
The vertex is the point (10,-6)
The x-coordinate of the vertex is 10
therefore
The equation of the axis of symmetry is equal to
Answer:
24 + c
Step-by-step explanation:
1. A person would need to write 20 checks each month for the two banks to charge the same amount in fees.
2. The account from Bank A would cost less if a person were to write 10 checks in a month.
Explanation:
1. Bank A = 0.25x + 4, Bank B = 0.2x + 5
0.25x + 4 = 0.2x + 5
0.05x = 1
x = 20
2. Bank A = 0.25(10) + 4 = $6.5
Bank B = 0.2(10) + 5 =$7
Therefore, it would cost less to write 10 checks from Bank A.
