how to find MP when discount percent and SP are given
Given:
Consider the discount percent and SP are given.
To find:
The MP.
Solution:
Let x% be the discount percent Then
[tex]SP=MP-x\%\text{ of }MP[/tex]
[tex]SP=MP-\dfrac{x}{100}MP[/tex]
[tex]SP=\left(1-\dfrac{x}{100}\right)MP[/tex]
[tex]SP=\left(\dfrac{100-x}{100}\right)MP[/tex]
Multiply both sides by 100.
[tex]100SP=(100-x)MP[/tex]
Divide both sides by [tex](100-x)[/tex].
[tex]\dfrac{100}{100-x}SP=MP[/tex]
Therefore, the formula for MP is [tex]MP=\dfrac{100}{100-x}SP[/tex], where x is the discount percentage.
does 4(x+1)=2x+4 have a solution
Answer: Yes, x = 0
Step-by-step explanation:
To solve for x, we will simplify things by distributing the 4 to the (x + 1) term. This means that our new equation will be
4x + 4 = 2x + 4
Now that we have our new equation, we will isolate x by subtracting 4 from both sides. After this, we will end up with
4x = 2x
At first glance, this may seem like no solution. What number has the same value when multiplied by 2 and by 4? Well, there infact is one. This can be shown when we subtract both sides by 2x to keep x on one side, and get
2x = 0
Divide by both sides to isolate x, and you get x = 0/2 = 0.
Thus, x = 0.

Judys town voted on a new speed limit. 95% of the 2,000 votes were in favor of the new speed limit. How many voted were in favor
Answer:
1,900 votes were in favor.
Step-by-step explanation:
Given that the statement indicates that 95% of the 2,000 votes were in favor, you can find the number of votes in favor by calculating the 95% of the total number of votes:
2000*95%=1900
According to this, the answer is that 1,900 votes were in favor.

Part A: A number is increased by 54. The sum is then divided by 9. The result is 21.
Write an equation to represent the description above. Use n for the number.
Equation:
Part B: Find the value of n. Show your work.
n =
Part C: Choose two numbers and use them to do the following:
Write an equation that shows your first number added to n equal to your second number. Solve your equation for n.
Equation:
Solution:
Answer:
(n +54)/9 = 21; 135= n
Step-by-step explanation:
(n+54)/9 = 21
n+54/9 *9= 21*9
n+54-54 = 189-54
n= 135
the first part is simply recognizing the order its written and the words used.
So to start off with, they use the turn "a number" so we know there's going to be some form of a variable. From there it says "increased by" rather than "multiplied" or "doubled" or something of that nature, so we know its adding 54 rather than multiplying. Then, the next part says that "the sum" which is another key term for addition, "is then divided by 9". So we can assume so far that a variable plus 54 is added together to get a number, which is then going to be taken and divided by 9. The last part says "the result is 21", which simply means that we need to end up with 21.
So once we gather all this information, we can put it together as so: (n +54)/ 9 = 21.
I put parentheses around the n + 54 to make sure that the equation is following the system of equations (PEMDAS).

A drawing of a triangle. The base equals 15 centimeters and height equals 8 centimeters.
Answer:
17
Step-by-step explanation:
If we are finding the long angled side (the hypotenuse), we must keep in mind the Pythagorean theorem. This states that in order to find the answer, we must follow: A squared + B squared = C squared. A and B are known as the legs and we use these for A and B. After squaring both 15 and 8 we get 225 + 64= 289. Now that we have our answer of 289, we can square this to find our hypotenuse which is 17. To find the square root, you multiply different numbers by themselves until you reach your answer. 17 x 17 = 289 so the hypotenuse is 17 centimeters long. I hope this helps! :)

Answer: The error is the number of sides, it should be 9 sides and not 25. Correct is 1 260 degrees
Step-by-step explanation:
The error is the number of sides, it should be 9 sides and not 25.
Polygon sum of interior angles formula: 180 x (n-2)
So here n = 9 (sides)
180 x (9-2)
180 x 7 = 1 260 degrees
Answer:
sum of interior angles = 180 * n - 2
n = number of sides
in this case, the shape has 9 sides so n = 9
so the correct answer should be
= 180 * (9-2)
= 180 * 7
= 1260

Write the nth term of the following sequence in terms of the first term of the sequence.
2, -4, 8, -16, . . .
Answer:
[tex]\bold{a_n=2\cdot(-2)^{n-1}}\\\\or\\\\\bold{a_n=(-1)^{n-1}\cdot2^{n}}[/tex]Step-by-step explanation:
-4÷2 = -2
8÷(-4) = -2
-16÷8 = -2
So this is a geometric sequence with the first term of 2 and a common ratio of -2
the nth term of a geometric sequence: [tex]a_n=a_1\cdot r^{n-1}[/tex]
Therefore:
[tex]a_n=2\cdot(-2)^{n-1}\\\\a_n=2\cdot(-1\cdot2)^{n-1}=2\cdot(-1)^{n-1}\cdot2^{n-1}=(-1)^{n-1}\cdot2^{n-1+1}\\\\a_n=(-1)^{n-1}\cdot2^{n}[/tex]

Using a six-sided die, you have rolled a 6 on each of four successive tosses. What is the probability of rolling a 6 on the next toss?
Answer:
The probability of rolling a 6 on the next toss = 1/6
Step-by-step explanation:
Given - Using a six-sided die, you have rolled a 6 on each of four successive tosses.
To find - What is the probability of rolling a 6 on the next toss?
Proof -
As the outcomes of previous rolls do not affect the outcomes of future rolls.
And there is one desired outcome and six possible outcomes.
So,
The probability of rolling a six on the fifth roll = 1/6 which is same as the probability of rolling a six on any given individual roll.
So,
The answer is -
The probability of rolling a 6 on the next toss = 1/6
In a six-sided die, by rolling a 6 on each of four successive tosses. the probability on the next toss is 1/6.
A six-sided die rolled 6 on each of four successive tosses.
What is probability?It is defined as the possibility of an event to happen is equal to the ratio of the number of favorable outcomes and the total number of outcomes.
The number of favorable outcomes of the die is 1 and the total number of outcomes of the six-sided die is 6.
So, The probability of rolling a six on the fifth roll = 1/6, which is the same as the probability of rolling a six on any given individual roll.
The probability of rolling a 6 on the next toss = 1/6.
