Cecilia bought a necklace made of silver and blue beads. The necklace had 30 silver beads and 36 blue beads. The information card on the necklace said that more than 1/3 of the beads are silver. Was the information on the card correct? Explain your answer.
Answers
We can solve this by making a ratio of silver to the total number of beads.
30/66 Divide both sides by 6
5/11>4/12?
Is 5/11 bigger than 1/3? Yep. It is. Therefore the information was correct.

Final answer:
Mathematical operations are often represented by specific words or phrases in word problems. Addition is represented by phrases such as 'in all', 'together', 'total', 'plus', or 'and', subtraction with 'less than', 'fewer than', 'minus', 'difference', or 'take away'. Multiplication may be represented by 'of', 'times', 'every', 'product', or 'at this rate', and division by 'per', 'each', 'out of', 'ratio of', 'quotient', or 'separated equally'.
Explanation:
Word or Phrase Representations in Math Operations
Mathematical operations often have keyword phrases associated with them. If you're asked to determine which operation a particular word or phrase represents, here's a simplified list:
- Addition is often represented by phrases such as 'in all', 'together', 'total', 'plus', or 'and'.
- Subtraction might be indicated by 'less than', 'fewer than', 'minus', 'difference', or 'take away'.
- Multiplication can be shown with 'of', 'times', 'every', 'product', or 'at this rate'.
- Division might be represented by 'per', 'each', 'out of', 'ratio of', 'quotient', or 'separated equally'.

Reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.
What is reflectional symmetry?
Consider a plane. Consider a design or shape on that plane. Now consider an axis.
If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.
Instead of that mirror intuition, we can also think that we sort of rotated that image about that considered axis, and after half rotation, the figure is again onto its plane. If that rotated figure looks alike to the initial figure, then that figure has rotational symmetry.
Thus, reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.

Exponents are used when we find the area of a shape, used in banking for finding compounding interest, and used to describe very large and very small numbers. (They are used for many other things, of course, but I don't think you want that kind of list)
You can use exponents to write numbers by writing the exponent for the number of times you are multiplying the base.

Answer:
The graph that represents a cubic function is:
Graph A.
Step-by-step explanation:
We know that for the graph of a cubic function it satisfies the property that:
- Both the ends of a graph must be in opposite directions.
- Also the graph attains the point of extrema at two points or zero point.
- Range is the set of real numbers.
- It has one inflection point.
- The graph has at least one real root.
Graph B:
It is a graph of a linear function.
Since a graph of a linear function is a straight line.
Graph C:
It is a graph of a quadratic function.
Since both the ends of the graph are in the same direction.
Graph D:
It is also a graph of a linear function.
As the graph is a straight line.
Graph A:
It is a graph of a cubic function.
Since it satisfies all the above properties.
