Answer:
Step-by-step explanation:
So there are two types of variables we need to focus on, the first is the dependent variable, the second is the independent variable ( which is the one in question). You asked about it in relation to mathematics, although even across the board, in science they both really mean the same thing. Here's an example, say you are taking a test, and the rubric for grading the test is 5 points (p) for every question (q) answered correctly. So given that information you can conclude that (p) is equal to 5 x the amount of questions you got right (p = 5q). The amount of points in this equation relies on how many questions you get right, you can't logically say that question (q) is equal to 5 points (p), because the questions don't depend on the points, the points depend on the amount of questions you get right. So that means since the points (p) depend on the # of questions you answered correctly, it is the dependent variable, there for by process of elimination you're independent variable is (q) since they don't rely on the points, the points rely on the questions. It all boils down to how well you can recognize this, and how complicated your question is, but hopefully this provided some insight.

Gareth buys 2 oranges he pays with £1 coin and gets 52p change work out the cost of 1 orange
The cost of one orange is 76 p.
What is division?Division is a mathematical operation that is used to determine the quotient of a set of numbers. The sign used to denote division is ÷.
What is the cost of 1 orange?The first step is to know how many pence makes a pound.
100 pence = 1 pound
The second step is to convert £1 52 p to pence
1 x 100 + 52 = 152p
The third step is to divide, 152 by 2

Answer:
The value of x is 2 and y is (-5)
Step-by-step explanation:
Given;-7x + y = – 19-2x + 3y = – 19To Find;The value of x and yBy Using Elimination Method;First name the equation
-7x + y = – 19 ...(1)-2x + 3y = – 19 ...(2)Now, Multiply equation (1) by 3 we get,
3 × (-7x + y = – 19)
-21x + 3y = – 57
Now, Eliminate
-21x + 3y = – 57
-2x + 3y = – 19
+ – +
-19x = -38
x = -38/-19
x = 2
Now, Put the value of x in equation (2) we get the value of y.
-7x + y = – 19
-7(2) + y = – 19
-14 + y = -19
-14 + 14 + y = -19 + 14
y = -5
Thus, The value of x is (-5) and the value of y is 2.
For Verification;-7x + y = – 19
-7(2) + (-5) = – 19
-14 – 5 = – 19
-19 = -19
-2x + 3y = – 19
-2(2) + 3(-5) = – 19
-4 – 15 = – 19
-19 = -19
Here, L.H.S = R.H.S
Hence Verified!

after a 25% price increase, a diamond is on sale for $2500. what was the original price?
Answer:
$3125 dollars
Step-by-step explanation:
Given the following question:
25% of 2500
In order to find the answer, we first will have to use the formula to calculate percentages to find 25% of 2500, then we add that answer onto the initial amount to have our answer.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{25\times 2500}{100} =25\times2500=62500\div100=625[/tex]
[tex]=625[/tex]
Now add:
[tex]2500+625=3125[/tex]
[tex]=3125[/tex]
Which means after a 25% increase the diamond will cost "$3125 dollars."
Hope this helps.

A right cylinder has a radius of 5 cm and a height of 3 cm.
Answer the following questions and make sure to show all your work.
(a) Find the Volume of the cylinder.
(b) If you wanted more volume in your cylinder, which of these two ideas would give the most Volume?
1. Doubling the radius to 10 cm, while the height remains 3 cm.
-OR-
2. Tripling the height to 9 cm, while the radius remains 5 cm.
Answer:
a) 235.62 cm³ (nearest hundredth)
b) 2. tripling the height to 9 cm, while the radius remains 5 cm, gives the most volume
Step-by-step explanation:
volume of a cylinder = [tex]2\pi r^2h[/tex] (where r is the radius and h is the height)
Given:
r = 5 cmh = 3 cma) ⇒ volume = [tex]\pi \times 5^2 \times 3=75\pi =235.62[/tex] cm³ (nearest hundredth)
b) Given:
r = 10 cmh = 3 cm⇒ volume = [tex]\pi \times 10^2 \times 3=300\pi =942.48[/tex] cm³ (nearest hundredth)
Given:
r = 5 cmh = 9 cm⇒ volume = [tex]\pi \times 5^2 \times 9=225\pi =706.86[/tex] cm³ (nearest hundredth)
Therefore, 2) tripling the height to 9 cm, while the radius remains 5 cm, gives the most volume

A line contains the points R (-5, -6) S (1, 5) and T (x, 10). Solve for x. Be sure to show and explain all work. ( How did this person get this answer?
By finding the line and evaluating, we will see that x = 41/11
How to find the value of x?
First, we need to get the line, for a line that passes through two points (x₁, y₁) and (x₂, y₂) the slope is:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So here we use the points (-5, -6) and (1, 5), the slope will be:
a = (5 - (-6))/(1 - (-5) = 11/6
So the line is something like:
y = (11/6)*x + b
To get the value of b, we use one of the given points, for example if we use the second point we must have:
5 = (11/6)*1 + b
5 - 11/6 = b
30/6 - 11/6 = b
19/6 = b
So the line is:
y = (11/6)*x + 19/6
Now, to find the value of x, we replace y by 10:
10 = (11/6)*x + 19/6
60/6 - 19/6 = (11/6)*x
41/6*(6/11) = x = 41/11
So the person in the image got it correct, but with other method.

In an election between two candidates 25% of the voters did not cast their votes a candidate scored 40% of the votes polled and was defeated by 900 votes.find the total number of voters.
Answer:
2000
Step-by-step explanation:
First, we have to find how many votes there were.
Since the losing candidate had 40% of the votes, that means the winning candidate had 60% of the votes.
Let x = amount of votes for losing candidate
x/40 = 900/60
Cross multiply
60x = 36,000
Divide both sides by 60
x = 600
The losing candidate had 600 votes
Add that number to 900 and we find the total amount of votes, which is 1500.
This number is the people who voted.
Now we have to find how many did not vote.
Since 25% of people did not vote, that makes people who did vote 75%
Let y = amount of voters who did not vote
y/25 = 1500/75
75y = 37,500
Divide both sides by 75
75y/75 = 37,500/75
y = 500
This means that 500 voters did not cast a vote.
Add that number to 1500 and we get that the total amount of voters is 2000

what ks the % of 4 = 2
Answer:
[tex]50\%[/tex]
Step-by-step explanation:
Let x be the percentage then...
[tex]x\%(4)=2[/tex]
Start by dividing both sides by 4:
[tex]x\%=\frac{2}{4}[/tex]
Simplify the fraction:
[tex]x\%=\frac{1}{2}[/tex]
Then, multiply the fraction by 50/50, so we can get a number over 100 (that number would be the percentage). Note we can only multiply it by 50/50 since it is essentially multiplying the fraction by 1.
[tex]x\%=\frac{1}{2}*\frac{50}{50}\\x\%=\frac{50}{100}\\x=50\%[/tex]
Solution:
Note that:
x% × 4 = 2Simplify the equation and solve.
x% × 4 = 2=> x/100 × 4 = 2=> x/25 = 2=> x = 2 x 25 = 50Hence, 50% of 4 is 2.
