Answer:
18
Explanation:
27 divided by 3 is 9. 9 times 2 equals 18.
Answer:
Focusing on your academic studies
Explanation:
Answer: {y∈R: y≤6} or [6,∞)
Explanation:
This problem doesn't require too much math. If you look at the equation given, you can see that it is a quadratic equation in the form of. Since this is a quadratic equation, we have an idea of that the graph would look like. It either curves up or down. Since this is a positive equation, , we know that this is going to curve up. In order to find the minimum of the curve, you would use .
This means the x value of the parabola is -2. To find the y, you plug -2 into the original equation.
Now that we know the y value of the minimum/vertex is 6, and it is determined that the parabola curves up, the range is y≤6 because the range starts at 6 and goes off toward infinity.
It should be noted that the number of days that will be taken to complete the sales target will be 27 days.
<h3>How to compute the sales target</h3>
From the complete information, the following can be deduced:
a + b = 1/30
b + c = 1/40
a + c = 1/60
Using the rules of algebra, b = 5/240, a = 3/240.
a + c = 1/60
3/240 + c = 1/60
c = 1/60 - 3/240
c = 1/240
Therefore, the 3 can do 9/240 in a day. The number of days required will be:
= 240/9 = 27 days
