There is sales of 40% off of the original price. If a mobile phone has a sale price of $180, what was the original price? Choose the correct answer.
A) $200
B) $280
C) $300
D) 320$
Answer:
$300
Step-by-step explanation:
If the phone has a discount of 40% that means it cost 60% of the original price
X= original price (100%)
$180 = 60% of the original price
X = 100%
CROSS MULTIPLICATION
60X = 180x100
60X = 18000
Divide both sides by 60
X = 300
Monte recorded the gas mileage, in miles per hour, of ten different cars he is considering buying: 34, 27, 30, 24, 28, 31, 42, 30, 29, and 19.
What is the median?
Answer:
29.4
Step-by-step explanation:
42+34=76
76+31=107
107+30+30=167
167+29=196
196+28=224
224+27=251
251+24=275
275+19=294
there are 10 cars that he wants
294/10=29.4
The median of the given data set is 29.5.
What are the mode and median?Mode is the highest frequency number while the median is the middle value of a data set after writing in either an increasing or decreasing manner.
For example;
Set { 1,2,2,3,4,5,6} here mode is 2 and median is 3.
As per the given mileage set,
34, 27, 30, 24, 28, 31, 42, 30, 29, and 19.
Write the above set in increasing order as
19,24,27,28,29,30,30,31,34,42
The median will be the middle value, since there is an even number so median will be as,
Median = (5th value + 6th value)/2
Median = (29 + 30)/2 = 29.5
Hence "The median of the given data set is 29.5".

3) Josie's collection of 39 coins includes twice as many nickels than quarters. If
the sum of the nickels and quarters is $4.55, How many quarters does Josie
have in her collection?
Answer:
13 quarters, 26 nickels.
Step-by-step explanation:
n will be number of nickels, q will be number of quarters, and we have 39 total coins
so n + q = 39 (number of nickels + number of quarters = 39 coins.
The problem also says there are twice as many nickels as quarters. so we can call the number of nickels n or we can call it 2q (2 times the number of quarters)
which means
n + q = 39
2q + q = 39
3q = 39
q = 13
and she has 2 times as many nickels as quarters... 2 x 13 = 26 nickels
LMK if you have questions.
If you want to double check the money,
n(0.05) + q(0.25) = 4.55 is the equation to use.
26(0.05) + 13(0.25) = 1.3 + 3.25 = $4.55

(iii) A relation between a and b such that point (a,b) isequidistant from the points (8,3) and (2,7)
Answer:
7.21 units
Step-by-step explanation:
GIven data
Point 1= (8,3)
x1= 8
y1= 3
Point 2= (2,7)
x2= 2
y2= 7
The expression for the distance between two points is given as
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((2-8)²+(7-3)²)
d=√((-6)²+(4)²)
d=√36+16
d=√52
d= 7.21
Hence the distance between the points is 7.21 units

Which table contains data with a nonproportional relationship?
A 2-column table with 3 rows. Column 1 is labeled x with entries 1, 2, 3. Column 2 is labeled y with entries 6, 12, 18.
A 2-column table with 3 rows. Column 1 is labeled x with entries 2, 4, 6. Column 2 is labeled y with entries 0, 2, 4.
A 2-column table with 3 rows. Column 1 is labeled x with entries 1, 2, 3. Column 2 is labeled y with entries 2, 4, 6.
A 2-column table with 3 rows. Column 1 is labeled x with entries 2, 4, 6. Column 2 is labeled y with entries negative 4, negative 8, negative 12.
Answer:
The second table, counting from the top.
X Y
2 0
4 2
6 4
Step-by-step explanation:
A proportional relationship is written as:
y = k*x
where k is called the constant of proportionality, is a real number different than zero.
Here we have different tables, if for two pairs (x, y) of the table we have the same value of k, then the relation is proportional. Also you can see that if x = 0, we have:
y = k*0 = 0
then a proportional relationship always has the point (0, 0)
A)
X Y
1 6
2 12
3 18
Let's use the first two pairs:
(1, 6)
6 = k*1
6/1 = k = 6
(2, 12)
12 = k*2
12/2 = k = 6
in both cases we have k = 6, then this is a proportional relationship.
B)
X Y
2 0
4 2
6 4
Here we can see the pair (2, 0)
This means that when x = 2, we have y = 0
Then this can not be a proportional relationship, because:
0 = k*2
k = 0
This is not a proportional relationship.
C)
X Y
1 2
2 4
3 6
Let's find k for the first two points.
(1, 2)
2 = k*1
2/1 = k = 2
(2, 4)
4 = k*2
4/2 = k = 2
In both cases we have k = 2, then this is a proportional relationship.
D)
X Y
2 -4
4 -8
6 -12
Let's find k for the first two points:
(2, -4)
-4 = k*2
-4/2 = k = -2
(4, -8)
-8 = k*4
-8/4 = k = -2
In both cases we have k = -2, then this is a proportional relationship.

your cell phone plan is by the minute. each minute of use cost $0.10. create a relation that represents the amount spent, A, per minute, m, of call time. Then, use the relation to find the amount spent if you talk 65 minutes.
Answer:
Talking 65 minutes, $ 6.50 must be paid.
Step-by-step explanation:
Since your cell phone plan is by the minute, and each minute of use cost $ 0.10, to create a relation that represents the amount spent, A, per minute, m, of call time, and then use the relation to find the amount spent if you talk 65 minutes, the following calculations must be performed:
0.10 x M = A
0.10 x 65 = A
6.50 = A
Thus, talking 65 minutes, $ 6.50 must be paid.

LITERALLY GIVING LIKE 30 POINTS OR WHATEVER IM DESPERATE PLEASE I NEED MODULE 4 NOTES FOR FLVS 8TH GRADE PRE-ALGEBRA?? I HAVE A DBA AND NEED NOTES I BEG ITS FOR MRS. MEURER'S CLASS
Answer: While I am not in your class and can not unfortunately specifically help with this I can still give you a basic overview of what you need to know in most pre algebra courses and you can hopefully then use this information in the best way possible.
Step-by-step explanation: Some of the basic pre algebra concepts include:
Knowing your basic addition, subtraction, multiplication, and division. I am assuming you know how to do this sort of math. For example, I mean problems such as 5+4 or 10/5, but if you do need help with these just ask me and I can help you further.
Basic variable usage: This means being able to solve problems such as x + 10 = 15. I can help walk you through this sort of problem. The variable (which is usually represented by the letter x) is used as a placeholder for an unknown number that you need to solve for. You can think of this more simply in the example I gave as What plus 10 is equal to 15. That might help you get the basics down if you can think of a problem that way. As you can probably tell now the answer would be 5. There may be also more advanced problems regarding variables but not all pre algebra classes will include this material so if you need a review in this you can ask me as well.
Another basic concept is the concept of solving equations. This can also mean using both addition and multiplication within one equation or things of that nature. These equations can look something like 18 - (5 + 3^2) + 7 and I can help walk you through a problem like this. An important fact to remember is the order of operations, which is the way in which you must solve more complex equations like this or if you need to think of it another way it can mean the way you break down an equation. You probably have heard of PEMDAS before and this is the way you can remember the order of operations. It is an acronym with each of the letters representing an operation. P = parenthesis E = exponents M = Multiplication D = division A = addition and S = subtraction. Now we can use this to solve the equation! First we should start within the parenthesis so lets only look at that portion of the problem for now to keep things simpler. Inside the parenthesis it said 5 + 3^2 We see addition and exponents within the parenthesis so because of PEMDAS we should start with the exponent. Exponents just mean the amount of times you need to multiply the base number by itself. The base number is the number the exponent is "attached" to. Our base number is 3 and the exponent is 2 which means we should do the following math 3 * 3 which equals 9 Now we can go back to our original problem inside the parenthesis. In place of the 3^2 we can instead put 9 now as we know its the answer for that part of the problem. What we have now is 5 + 9 and we can simply add that to get 14. This means inside the parenthesis we can replace with just the number 14 as we have already solved everything we need for it. The equation now looks like --> 18 - (14) + 7. Now what we have left is addition and subtraction. Remember on PEMDAS how multiplication and division were next to each other along with addition and subtraction? For these 4 just because they are next to each other does not dictate the other rather when you are dealing with either just multiplication and division in a problem you work left to right and the same goes for addition and subtraction and since our resulting problem only has addition and subtraction left we will simply just work from the left of the equation to the right. Our problem as of now is 18 - (14) + 7. 18 - 14 = 4 so we can now have the equation be 4 + 7 and after adding we get our answer which is 11! I hope you were able to follow along with that and my explanations were satisfactory.
Hopefully at least some of this included in your module 4 but if you would elaborate more I would more than happily assist you more so please do not hesitate to reach out :)

A bouncing ball reaches a height of 54 inches at its first peak, 36 inches at its second peak, and 24 inches at its third peak. Which formula represents this scenario?
f(x) = 54(two-thirds) Superscript x
f(x) = 54(two-thirds) Superscript x minus 1
f(x) = Two-thirds(54)x
f(x) = Two-thirds(54)x – 1
Answer:
f(x) = 54(two-thirds) Superscript x minus 1
Step-by-step explanation:
Given that:
First peak : 36 / 54=2/3
Second peak : 24 / 36 = 2/3
The common ratio here is 2/3 ; which mean each bounce height is 2/3 of previous height
Modeling this using geometric progression :
An=a1r^(n-1)
An = nth term of a geometric progression
a1=first term
r=common ratio = 2/3
n = nth term
a1=54
Substituting into the above formular :
An=54(2/3)^(n-1)
