Answer:
2:1
Step-by-step explanation:
2/3 of the class is girls, so that means 1/3 of the class is boys. Make the number of people in the class x. The equasion would be (2/3x)/(1/3x) This simplifies to 2:1
Answer:
no thank you
Step-by-step explanation:
In this problem, it will be helpful to know the vertex form of a parabola, which is listed below:
is a constant which helps to determine whether the parabola opens up or down. If 
, then the parabola opens downward and if 
, the parabola opens upwards
is the vertex of the parabola
By looking at the graph, we can first see that the graph opens downwards, meaning that . Thus, choices C and D are not valid. Now, let's use the vertex of the parabola to complete the equation.
The vertex of this parabola is (-1, 3), as shown by the graph. When we substitute this into our formula, we get:
The answer is a, 
.

Answer:
You can enter simple formulas to add, divide, multiply, and subtract two or more numeric values. Or use the AutoSum feature to quickly total a series of values without entering them manually in a formula. After you create a formula, you can copy it into adjacent cells — no need to create the same formula over and over again.
