Anytime point A is on line BC, AB+BC=BC
Yes he is correct because -18/3 would turn into -6 a whole number
Answer:
14 candy Bars
Step-by-step explanation:
Let's under the question before we attempt it.
Total number of Candy Brooklyn is supposed to sell = 20
Percentage of Candy Bars sold= 70%
To know the exact number of Candy sold, it's means we must know the exact value of 70% of 20.
To solve this, we just proceed with mathematical operations.
Therefore:
70% of 20
= 70 / 100 * 20
= 1400 / 100
= 14.
It therefore means that, Brooklyn sold 14 Candy Bars

Step-by-step explanation:
The equation of a parabola with focus at (h, k) and the directrix y = p is given by the following formula:
(y - k)^2 = 4 * f * (x - h)
In this case, the focus is at the origin (0, 0) and the directrix is the line y = -1.3, so the equation representing the cross section of the reflector is:
y^2 = 4 * f * x
= 4 * (-1.3) * x
= -5.2x
The depth of the reflector is the distance from the vertex to the directrix. In this case, the vertex is at the origin, so the depth is simply the distance from the origin to the line y = -1.3. Since the directrix is a horizontal line, this distance is simply the absolute value of the y-coordinate of the line, which is 1.3 inches. Therefore, the depth of the reflector is approximately 1.3 inches.
