If y is a positive integer, for how many different values of y is [tex]\sqrt[3]{144\y}[/tex]a whole number?
Answer:
2
Explanation:
I'll explain later, it has to do with prime factors, and perfect cubes.
The two values of y that work are 18, and 144.
³√(144/18) = ³√(8) = 2 [whole number]
³√(144/144) = ³√(1) = 1 [whole number]

Step-by-step explanation:
A group of friends is going to a baseball game. A general admission ticket to the game costs $9.00. A ticket for a fan club member costs $6.00. The expression 9x + 6y models the cost for the entire group of friends. Which is the meaning of the term, 9x?
Answer:
See explanation!
Step-by-step explanation:
The term 9x is comprised of two values: 9 and x. The 9 represents the cost of the general admission tickets. Since the expression is representing the total cost for the group of friends, the number of friends attending must be represented somehow in the equation. Since the $9 is paired with the x, this means that x represents how many of the friends are paying the general admission price. After interpreting both values within the term, the meaning of the term 9x is simply just the total cost of the friends that are paying the general admission price! Hope this helps!

A student observes a difference in the activity level of fish at a pet store. The fish in an aquarium near the window are swimming around more quickly tha the fish in an aquarium placed in the back of the store. The student forms a hypothesis about the effect of sunlight on fish activity levels and arranges to conduct an experiment. Which variable could be an independent variable in the student's experiment? types of fish sold speed of swimming fish amount of time fish were active temperature of water in fish tank
Answer: Types of fish sold
The type of fish sold is the independent variable in the student's experiment. So, the correct option is (A).
What are Variables?
A variable is any kind of characteristic, number, or quantity which can be measured or counted. It can also be called a data item. Examples of variables are age, sex, occupation income and expenses, country of birth, capital expenditure, class grade, eye color, and vehicle type.
There are two types of Variables are:
1. Dependent variable
A dependent variable is a type of variable which changes as the result of independent variable manipulation which is the outcome interested in measuring, and it "depends on" the independent variable.
2. Independent variable
An independent variable is the type of variable which is manipulated or varied in an experimental study in order to detect its effects. This is "independent" because it is not affected by any other variable in the study.
In above case, this is independent because types of fish characteristic is not dependent for the experiment.
Thus, the type of fish sold is the independent variable in the student's experiment. So, the correct option is (A).

what is 9 : 45 = 6 : ?
Answer:6:45
Step-by-step explanation:
Answer:
x = 30
Step-by-step explanation:
a ratio is just a fraction
9:45 = 9/45
6:x = 6/x
now you have 9/45 = 6/x
cross multiply:
9 * x = 45 * 6
9x = 270
divide both sides by 9
9x/9 = 270/9
x = 30

This is a reflection over the x-axis so its only the y-intercept that changes.
Answer:
its a reflection
Step-by-step explanation:
If it were a rotation, it wouldnt have overlapped.
If it were a translation, It would have been the wrong way up and not overlapping.
When reflected over line x, it will overlap because it stays rigid and does not change shape or size.
