Which of the following does NOT have a unit price of $24 for one sweater?
$38 for 2 sweaters
$72 for 3 sweaters
$96 for 4 sweaters
$120 for 5 sweaters
Answer:
$38 for 2 sweaters
Step-by-step explanation:
Every price for all other sweater options are divisible by 24, since it is the unit price (meaning 1 sweater = $24). 38 is not divisible by 24, but by 19. This means it does not follow the unit price. It would be a special sale.

A mixed nuts factory makes a 10 pound mixture of almonds, walnuts, and
cashews. Almonds cost $1.25 per pound, walnuts cost $2.75 per pound,
and cashews cost $3.15 per pound. The mixture calls for twice as many
almonds as walnuts. The total cost of the mixture is $18.90. How much of
each ingredient did the store use?
This is a System of equations problem
Answer
x+y+z=10
1.25x+2.75x+3.15x+18.90
x=2z
Step-by-step explanation:
x=almonds
y=walnuts
z=cashews
9514 1404 393
Answer:
6 pounds almonds3 pounds walnuts1 pound cashewsStep-by-step explanation:
We can let a, w, c represent pounds of almonds, walnuts, and cashews, respectively. Then the given relations are ...
a +w +c = 10 . . . . . total pounds of nut mix
a = 2w . . . . . . . . . twice as many almonds as walnuts
1.25a +2.75w +3.15c = 18.90 . . . . total cost of the mix
__
Solving the system of equations can proceed by any of the methods you have learned for systems of two equations in two unknowns. Substitution, elimination, and matrix methods all work. Graphing methods are also available.
We can easily reduce this system to two equations in two unknowns by using the second equation to substitute for 'a'.
2w +w +c = 10 ⇒ 3w +c = 10
1.25(2w) +2.75w +3.15c = 18.90 ⇒ 5.25w +3.15c = 18.90
Solving the first of these equations for c, then substituting into the second of these equations gives ...
c = 10 -3w
5.25w +3.15(10 -3w) = 18.90
-4.20w +31.50 = 18.90 . . . . simplify
12.60 = 4.20w . . . . . . . . . . . add 4.20w -18.90
3 = w . . . . . . . . . . . . . . . . . . . divide by 4.20
c = 10 -3(3) = 1 . . . . . . . . . . . use the expression for c
a = 2(3) = 6 . . . . . . . . . . . . . use the expression for a
The nut mix used 6 pounds of almonds, 3 pounds of walnuts, and 1 pound of cashews.

Additional comment
The attached graph shows one way to obtain a graphical solution. The first and third equations were solved for c, and those expressions were set equal to obtain the graph for the red line. The blue line is the second equation. Here, we have used (x, y) for (a, w). The solution for these variables is (a, w) = (6, 3). Using the first expression for c gives c = 10 -(6+3) = 1. This is the same solution as above.
What’s an equivalent fractions for 6/8 with a 20 as the new denominator
Answer:
15/20
Step-by-step explanation:
Divide your denominator by your previous/compared denominator (20/8) to find the number as your numerator. Take the found numerator (2.5) and multiply it times the compared numerator (2.5 x 6) giving your 15/20.

Javier says that when you add a positive and a negative number the sum is always negative. is Javier or statement true or false explain your reasoning
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The Above statement is incorrect, because if the positive number is equal to the numerical value of negative number then their sum will be zero, and If the numerical value of positive number is greater than that of negative number then the sum will be a positive number, so the probability is of both three, the sum can be positive, negative as well as zero.
Answer:
The above statement is false.
Explanation:
If the positive number is greater than the negative, then it will stay positive.
Lindsey sold stationery to her family and her mother's friends shw deposited the $125 shw earned in a savings account. The account earns 5.18% interest annually. If she does not deposit or withdraw any money for 18 months how much will she have in her account
Answer:
$134.71
Step-by-step explanation:
A = P(1 + rt)
A = Amount after t months or years
P = Principal or amount saved
r = interest rate = 5.18% = 0.0518
t = time.in years = 18 months
= 1 year and 6 month
= 1.5 year
A = $125( 1 + 0.0518 × 1.5)
A = $125 ( 1 + 0.0777)
A = $125(1.0777)
A = $134.71

Let A, B, C, X be sets with A, B, and C are subsets of X. Prove the following set equalities
a) (A ∩ B)' = A' ∪ B'
Answer:
[tex] let \:x \in (A\cap B)'\\\Rightarrow x \notin (A\cap B) \\\Rightarrow x \notin A \:or\: x\notin B\\ \Rightarrow x \in A' \:or \:x \in B'\\\Rightarrow x \in A' \cup B'\\\therefore (A ∩ B)' = A' ∪ B' [/tex]
It is proved that , A Intersection B complement is equal to the union of the complements of the sets A and B i.e., (A ∩ B)' = A' ∪ B'.
What is a set ?
Sets are represented as a collection of well-defined objects or elements.
It is given that A , B , C , X are sets with A , B and C are subsets of X.
Let's assume X be an element of A intersection B complement. or (A ∩ B)'.
i.e.,
X ∈ (A ∩ B)'
Also , we can say that :
X ∉ ( A ∩ B)
This implies :
X ∉ A or X ∉ B
or we can also say that :
X ∈ A' or X ∈ B'
or
X ∈ A' ∪ B'
So , we can conclude that :
(A ∩ B)' = A' ∪ B'
or A Intersection B complement is equal to the union of the complements of the sets A and B.
Therefore , it is proved that , A Intersection B complement is equal to the union of the complements of the sets A and B i.e., (A ∩ B)' = A' ∪ B'.

Question
A square has an area of 81 square inches. How long are its sides?
Someone please I need help ASAP !!
Answer:
Step-by-step explanation:
it is like 9x9=81
but yeah like he said it is a square so all sides are the same
but that is if you want to find the parameter
this question is talking about area
so when a question gives you an area you ask yourself what can be multiplied by what in order to give me the area
or since all sides are the same like he said you could just do simple division and do 81/9 which will =9
and since the question mentions that the area is in square inches it is obvious that the answer would be put in inches
answer: 9 inches
What must be the length of PQ in order for AJKL to be
similar PQR
9514 1404 393
Answer:
(d) 18
Step-by-step explanation:
If ΔJKL ~ ΔPQR, then we must have ...
PQ/JK = QR/KL . . . . . ratios of corresponding sides are the same
PQ = JK×QR/KL = 12×9/6 = 2×9
PQ = 18
Answer:
18
Step-by-step explanation:
The scale factor for this is 1.5,
JL = PR
JL is 14, and PR is 21, 14 * 1.5 = 21
KL = QR
KL is 6, and QR is 9, 6 * 1.5 = 9
So we do the same for JK and PQ
Since PQ is 12, we need to find what 12 * 1.5 is.
12 * 1.5 = 18
PQ = 18

Ruby has $130 saved. She is saving $15 dollars more each week. In how many weeks will she have $400 saved to buy the new phone she wants?
You answer is In 18 weeks he'll have the $400 for the new phone.
I know this because she needs 400 but already has 130 so (400-130=270)
This means that Ruby is missing 270 to get to the 400 that he needs for the phone.He gets $15 per week so now that's (270/15=18).Which means that in 18 weeks Ruby will complete to full $400 that he needs for a new phone.
The required solution of weeks will she have $400 saved to buy the new phone she wants is 18 weeks.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
Ruby has $130 saved. She is saving $15 dollars more each week.
According to given question we have
let x represent the number of weeks
she saves $15 each week,
then in x weeks she will save = 15x dollars.
Add this to the 130 she has already saved, and at the end of each week we get
15x + 130dollars.
So,
15x + 130 = 400
Subtract 130 from both sides we get
15x-130+130=400-130
15x=270
Divide by 15 on both sides we get
x=18
Therefore, the required solution of weeks will she have $400 saved to buy the new phone she wants is 18 weeks.
