Answer:
466 student
Step-by-step explanation:
The number of students that like at most 2 kinds of these chocolate candies can be gotten from subtracting the number of students that like more than 2 candies from the total number of high school students.
Since 34 like all three kinds of chocolate candy, hence:
Number of students that like at most 2 kinds of these chocolate candies = 500 - 34 = 466
466 students like at most 2 kinds of these chocolate candies
Elena packed 48 cubes.
Each cube has an edge of 1 centimeter.
The number of layers that Elena can make depends on how each layer is arranged and depends on how many cubes are there in a layer.
Assume that each layer has only 1 cube, then there are 48 layers.
Step-by-step explanation:
We need to find an expression for
.
We can solve it as follows.
We know that,

So,

or

Hence, this is the required solution.
Is it 4 times x or 4 to the power of x, if the first one then, 8x-24x. if the second then 8^-6x
