Answer:
48
Step-by-step explanation:
you need 4 one-fourth cups to make one cup. multiply 12 by 4 and you get 48
By dividing the total amount of soup (12 cups) by the amount of soup per bowl (1/4 cup), we find that Joe can fill 48 bowls.
The student poses a question related to division and unit conversion. To address the student's question, we should calculate how many bowls Joe can fill by dividing the total amount of soup by the amount used for each bowl. Joe has 12 cups of soup and uses 1/4 cup of soup for each bowl. The calculation would be:
Number of bowls = Total cups of soup / Cups of soup per bowl
Number of bowls = 12 cups / 1/4 cup per bowl
Number of bowls = 12 / 0.25
Number of bowls = 48
Therefore, Joe will use 48 bowls to serve the 12 cups of soup, with 1/4 cup of soup in each bowl.
The art club at a school raised $248 at a car wash. They spent $206 to set up an art show, and raised $316 at the art show by selling artwork the members had made. How much money did the club have after the show?
Answer:
Money club have after the show is $358 .
Step-by-step explanation:
As given
The art club at a school raised $248 at a car wash.
They spent $206 to set up an art show, and raised $316 at the art show by selling artwork the members had made.
Than
Money club have after the show = school raised money at a car wash + Raised money at the art show - spent money to set up an art show.
Money club have after the show = 248 + 316 - 206
Money club have after the show = 564 - 206
Money club have after the show = $358
Therefore money club have after the show is $358 .
Answer:
It is 358.
Step-by-step explanation:
The club started with $248, and then spent $206.
248−206=42
The club had $42, left after they spent for the art show.
Then, they raised another $316, at the show.
42 + 316 = 358
Answer: 358

Select all of the values that are solutions of x2 + 20 = 12x. x = -10 x = -2 x = 2 x = 10
Answer:
2, and 10
Step-by-step explanation:
Let's work through each one.
First, plug -10 into the equation:
-10² + 20 = 12 x -10?
-10² = 100
100 + 20 = 120
12 x -10 = -120
120 = -120? False!
But, using these same calculations, we can see that 10 is a correct answer.
Because everything's the same up to 12 x 10 = 120.
120 = 120
Same with 2 and -2
-2 does not work, but 2 does.
2² + 20 = 12 x 2?
4 + 20 = 24?
24 = 24? True!
The solution of the given quadratic equation is x = 2 and x = 10.
What is a quadratic equation?A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared.
Given a quadratic equation, x²+20 = -12x
x²-12x+20 = 0
On factorizing the equation,
x²-10x-2x+20 = 0
x(x-10)-2(x-10) = 0
(x-10)(x-2) = 0
x = 10 or x = 2
Hence, the solution of the given quadratic equation is x = 2 and x = 10.

between a mixture and substance which can be separated into components & what are the two ways?
Answer:
Step-by-step explanation:
Introduction:
Mixtures are not unique to chemistry; we encounter them on a daily basis. The food and drinks
we consume, the fuel we use in our vehicles, building materials, soil, air, and ordinary water are
all mixtures. In fact, very few common materials in the world are pure. Any material made up
of two or more substances that are not chemically combined is a mixture. It is not difficult to
separate the components of a mixture if you take advantage of differences in physical properties
of the components.
1. Sublimation. Some substances change directly from a solid to a gas when they
are heated. The reverse process, when the vapor goes back to the solid phase
without a liquid state in between, is called deposition. Some solids which sublime
are iodine, caffeine, and paradichlorobenzene (mothballs). Dry ice sublimes also.
2 Extraction. This uses a solvent to selectively dissolve one component of the
solid mixture. With this technique, a soluble substance can be separated from an
insoluble substance.
3. Decantation. This separates a liquid from insoluble solid sediment by carefully
pouring the liquid from the solid without disturbing the solid.
4. Filtration. This separates a solid from a liquid through the use of a porous
material as a filter. Paper, charcoal, or sand can serve as a filter. These materials
trap the solid but let the liquid pass through (see diagram in Procedure section).
5. Evaporation. This is the process of heating a mixture in order to remove a
liquid that evaporates easily, leaving a dry residue.
Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.

A set of data follows a nonstandard normal distribution curve. Find the probability that a randomly selected value will be between 660 and 680 given mean of 715 and a standard deviation of 24
Options:
0.9169
0.0611
0.7100
0.8300
Answer:
0.0611
Step-by-step explanation:
Answer:
B. 0.0611
Step-by-step explanation:
We have been given that a data set which follows a nonstandard normal distribution curve and mean of data set is 715 and standard deviation is 24.
To find the probability that a randomly selected value will be between 660 and 680 we will use probability formula to find the values between two z-scores.
First of all let us find z-score for our given values using z-score formula.
[tex]z=\frac{x-\mu}{\sigma}[/tex], where,
[tex]z=\text{ z-score}[/tex],
[tex]x=\text{Random sample score}[/tex],
[tex]\mu=\text{ Mean}[/tex],
[tex]\sigma=\text{ Standard deviation}[/tex].
Let us find z-score for random score 660.
[tex]z=\frac{660-715}{24}[/tex]
[tex]z=\frac{-55}{24}[/tex]
[tex]z=-2.29[/tex]
Let us find z-score for random score 680.
[tex]z=\frac{680-715}{24}[/tex]
[tex]z=\frac{-35}{24}[/tex]
[tex]z=-1.458\approx -1.46[/tex]
We will use formula [tex]P(a<z<b)=P(z<b)-P(z<a)[/tex] to find the probability between our given values.
Upon substituting our given values in above formula we will get,
[tex]P(-2.29<z<-1.46)=P(z<-1.45)-P(z<-2.29)[/tex]
Using normal distribution table we will get,
[tex]P(-2.29<z<-1.46)=0.07215-0.01101[/tex]
[tex]P(-2.29<z<-1.46)=0.06114[/tex]
Therefore, the probability that a randomly selected value will be between 660 and 680 is 0.0611 and option B is the correct choice.

a.the coordinates cannot prove a 180° rotation.
b.the y-coordinates of the points on δa'b'c' have opposite signs from the corresponding points on δabc.
c.the x-coordinates of the points on δa'b'c' have opposite signs from the corresponding points on δabc. eliminate
d.both the x and y coordinates of the points on δa'b'c' have opposite signs from the corresponding points on δabc?
Answer:
Option d is correct.
Both the x and y coordinates of the point on δa'b'c' have opposite signs from the corresponding points on δabc.
Step-by-step explanation:
The rule of 180 degree rotation about the origin is:
[tex](x, y) \rightarrow (-x , -y)[/tex]
Since a Rotation of a point through 180°, about the origin when a point a(h, k) is rotated about the origin through 180° in anticlockwise or clockwise direction.
then, By the rule of 180 degree rotation;
[tex]a(h, k) \rightarrow a'(-h , -k)[/tex]
so, it takes the new position i.e, [tex]a'(-h , -k)[/tex]
Therefore, both the x and y coordinates of the point on δa'b'c' have opposite signs from the corresponding points on δabc.
A box has a volume of 128 feet. The length is twice the width and the height is the same as the width. What are the dimensions of the box?
Answer: width = 4 ft, length = 8 ft, height = 4 ft
Step-by-step explanation:
width (w): w
length (L): 2w
height (h): w
Volume (V) = w * L * h
128 = w(2w)(w)
128 = 2w³
64 = w³
∛64 = ∛w³
4 = w
width (w): w = 4
length (L): 2w = 2(4) = 8
height (h): w = 4

Enter your answer in the box.
Answer:
x = 5
Step-by-step explanation:
in ΔABC , AB = BC , hence triangle is isosceles, thus
∠A = ∠C = 73° ( base angles are equal )
the sum of the 3 angles in a triangle = 180°
subtract the sum of the base angles from 180 for ∠B
∠B = 180° - (73 + 73)° = 34°
⇒ 6x + 4 = 34 ( subtract 4 from both sides )
6x = 30 ( divide both sides by 6 )

Jason is considering taking out a 20-year loan with monthly payments of $140 at an APR of 5.1%, compounded monthly, and this equates to a loan of $21,037.05. Assuming that the APR and the length of the loan remain fixed, which of these is a correct statement?
A.If Jason's monthly payment were $190, the amount of the loan that he is considering taking out would be less than $21,037.05.
B.If Jason's monthly payment were $110, the amount of the loan that he is considering taking out would be more than $21,037.05.
C.If Jason's monthly payment were $130, the amount of the loan that he is considering taking out would be less than $21,037.05.
D.If Jason's monthly payment were $120, the amount of the loan that he is considering taking out would be more than $21,037.05.
Answer:
C - If Jason's monthly payment were $130, the amount of the loan that he is considering taking out would be less than $21,037.05.
Step-by-step explanation:
The EMI formula is :
[tex]\frac{p*r*(1+r)^{n} }{(1+r)^{n}-1 }[/tex]
here r = 5.1/12/100=0.00425
p = 21037.05
and n = 20*12 = 240
Putting the values in formula we get
[tex]\frac{21037.05*0.00425*(1.00425)^{240} }{(1.00425)^{240}-1 }[/tex]
= (21037.05*0.00425*2.767)/1.767 = $140.00
Hence, for an amount of $21,037.05, the monthly payment becomes $140. So, if Jason is paying $130, he must have taken less loan than $21037.05.
So, option C is correct.
If you want to calculate, lets take p = x and emi = 130 and put the values in above formula. (r and n are same)
130=(x*0.00425*2.767)/1.767
130= 0.0066x
x = $19696.96(approx) (This shows that the loan will be less than $21037.05)
Angle dfg and angle fkl are complementary angles, m angle dfg= x+4, and m anlge jkl = x+10 . Find the measure of each angle
Answer:
42° and 48°
Step-by-step explanation:
Complementary angles sum to 90°, hence
x + 10 + x + 4 = 90
2x + 14 = 90 ( subtract 14 from both sides )
2x = 76 ( divide both sides by 2 )
x = 38
x + 10 = 38 + 10 = 48° and x + 4 = 38 + 4 = 42°

The inverse of the function g(x)=-4/3x+2 is
[tex]g^{-1}(x) = -\frac{3}{4}x+\frac{3}{2}[/tex]
The given function is:
[tex]g(x) = -\frac{4}{3}x + 2[/tex]
To find the inverse of the function g(x), follow the steps below
Make x the subject of the formula
[tex]g(x) = -\frac{4}{3}x+2\\\\ -\frac{4}{3}x = g(x) - 2\\\\-4x=3g(x)-6\\\\x = -\frac{3}{4}g(x)+\frac{6}{4} \\\\x = -\frac{3}{4}g(x)+\frac{3}{2}[/tex]
Replace x by [tex]g^{-1}(x)[/tex] and replace g(x) by x
The inverse function therefore becomes:
[tex]g^{-1}(x) = -\frac{3}{4}x+\frac{3}{2}[/tex]
The inverse of the function g(x)=-4/3x+2 is [tex]g^{-1}(x) = -\frac{3}{4}x+\frac{3}{2}[/tex]

Classify the series as arithmetic or geometric then determine whether the series is convergent or divergent
Answer: Arithmetic , Divergent
Step-by-step explanation:
Given sequence is
{aₙ} = { 4 , 10/3 , 8/ 3 , 2 , . . . }
To check whether the sequence is geometric or not , we divide second term by first term to find the common ratio . Then we again divide third term by second term to get common ratio .
The common ratio we get would same , then it is geometric .
10/3 10 5
r₁ = ----------- = ------ = ------
4 12 6
8/3 8 3 4
r₂= ---------- = ---------- * ------------ = -----
10/ 3 3 10 5
Thus the common ratio are not same . So the sequence is not geometric .
Now we check for arithmetic .
We take difference of second and first term and then difference of third and second term . If it will be same then it is arithmetic . This is called common difference , d .
10 - 2
d₁ = ------ - 4 = -------
3 3
8 10 - 2
d₂ = ------ - -------- = ---------
3 3 3
Thus the common difference is same .
So the given sequence is arithmetic .
To find whether it is convergent or divergent , we need to write sum of n terms first .
Formula for finding sum of n terms of arithmetic sequence is
n
sₙ = ----- [ 2a + ( n - 1 ) d]
2
We have a = 4 , d = - 2/3 .
Plug in this formula we get
n n 2 2
sₙ = ------- [ 2 * 4 + ( n - 1 ) ( -2/3) ] = ------ [ 8 - ----- n + ------ ]
2 2 3 3
n 26 2
sₙ = ------ [ ------ - ------- n ]
2 3 3
To check whether it is convergent or divergent , we take limit sₙ approaches to infinity .
n 26 2
lim sₙ = lim { --- [ --- - ------ n ] } = - ∞
n → ∞ n→∞ 2 3 3
As the sequence diverge , thus the series is divergent .
Thus given series is arithmetic , divergent .

in parallelogram ABCD diagonals AC and BD intersect at Point E, BE = 2x^2 -3x + D = x^2 + 10 what is BD
Answer
Given the statement: In parallelogram ABCD, diagonals AC and BD intersects at point E.
Given that ABCD is a parallelogram.
As, we know that in a parallelogram diagonals bisect each other.
Since AC and BD intersect at E, and we get E is the mid point of both diagonals AC and BD.
⇒ BE = DE .....[1]
Substitute the given values of [tex]BE = 2x^2 -3x[/tex] and [tex]DE = x^2+10[/tex] in [1] we have;
[tex]2x^2-3x = x^2+10[/tex]
Subtract [tex]x^2[/tex] on both sides we get;
[tex]2x^2-3x-x^2 = x^2+10-x^2[/tex]
Simplify:
[tex]x^2-3x =10[/tex]
Subtract 10 on both sides we get;
[tex]x^2-3x-10 =0[/tex]
or
[tex]x^2-5x+2x-10 =0[/tex]
[tex]x(x-5)+2(x-5)=0[/tex]
[tex](x-5)(x+2)=0[/tex]
equate these factors equal to zero we get;
(x-5) = 0 and (x+2) = 0
we have;
x = 5 and x = -2
Since, x cannot be negative.
So, x =5
[tex]BE = DE = x^2+10 = (5)^2+10 = 25+10 = 35 units[/tex]
Diagonals BD = BE + DE = 35 + 35 =70 units.
Therefore, the value of BD = 70 units.

Let us assume that the number of square yards for carpeting used be x.
Let us assume that the total cost of the charged by the companies be y.
As given
Country Carpets charges $22 per square yard for carpeting, and an additional installation fee of $100.
Than the equation becomes
y = 22x + 100
As given
City Carpets charges $25 per square yard for the same carpeting, and an additional installation fee of $70.
Than the equation becomes
y = 25x + 70
Than the two equations are
y = 22x + 100 and y = 25x + 70
Than compare the two equations are
22x + 100 = 25x + 70
25x - 22x = 100 - 70
3x = 30
[tex]x = \frac{30}{3}[/tex]
x = 10 square yards .
Therefore the total cost charged by the two companies will be the same for 10 square yards of carpeting .

Answer:
35
Step-by-step explanation:
It’s a 90 degree angle. 3x35=105 and 105-15=90
Answer:
x = 35
Step-by-step explanation:
Angle JML is 90 degrees
3x-15 = 90
Add 15 to each side
3x-15+15 = 90+15
3x = 105
Divide each side by 3
3x/3 =105/3
x = 35
HELP!!!!!!!!!!!!!!! I think its option 1 and 4 but I cant tell!
Answer:
3 and 4
Step-by-step explanation:
We apply 2 transformations here.
f(x) ----> f(x + a) - this is a shift of a units to the left.
f(x) ---- > f(x) + a - this is a shift of a units vertically up.
x - 1 ----> x + 2 shifts it 3 units to the left.
3 ---->5 shifts it 2 units up.
Answer:
Options 3 & 4
Step-by-step explanation:
Recall, an exponential function has the basic form
[tex]y=ab^{x+h}+k[/tex].
a produces a vertical stretch or shrink b is the ratex is the input valueh shifts the function left and right opposite to the sign of itk shifts the function up and downThus [tex]f(x)=2^{x-1} +3[/tex] is shifted to the right 1 unit and up 3 units.\\
This means that [tex]g(x)=2^{x+2}+5[/tex] is shifted to the left 2 units and up five units.
Remember it had already been shifted up 3 so, moving up to 5 is a movement of 2 units. Option 3 is correct.
Also, remember the function started 1 unit to the right and then shifted left to 2. This would be 1--2=3 units in total were shift from f(x) to g(x). This makes Option 4 correct too.
Rectangle ABCD has vertices A(3, 5), B(5,5), C(5, 1) and D(3, 1). Drag and drop the coordinates of each vertex when rectangle ABCD is rotated 90° counter-clockwise around the origin.
Answer:
Given the coordinates of rectangle ABCD are;
A = (3, 5)
B = (5,5)
C = (5, 1) and
D = (3, 1)
The rule of rotation 90 degree counter-clockwise around the origin is given by;
[tex](x, y) \rightarrow (-y, x)[/tex]
Now, the coordinates of each vertex when rectangle ABCD is rotated 90 degree counter-clockwise around the origin are;
[tex]A(3, 5) \rightarrow A'(-5, 3)[/tex]
[tex]B(5, 5) \rightarrow B'(-5, 5)[/tex]
[tex]C(5, 1) \rightarrow C'(-1, 5)[/tex]
[tex]D(3, 1) \rightarrow D'(-1, 3)[/tex]
Will someone please explain this to me? I'm not looking for an answer, just an explaination.The quotient of a number and 2 is the same as the difference of the number doubled and 3. What is the number?
Answer:
2
Step-by-step explanation:
let the number be n then
[tex]\frac{n}{2}[/tex] = 2n - 3 ( myltiply both sides by 2 )
n = 4n - 6 ( subtract 4n from both sides )
- 3n = - 6 ( divide both sides by - 3 )
n = 2
check
[tex]\frac{2}{2}[/tex] = 1 and (2 × 2 ) - 3 = 4 - 3 =1

Samantha has at most 75$ for a local day spa for her birthday. She plans to get a haircut for 32$ and a manicure for 26$ plus have more money left over. What is the maximum amount she would have left
Final answer:
After subtracting the cost of a haircut ($32) and a manicure ($26) from Samantha's spa day budget of $75, she would have a maximum of $17 left over.
Explanation:
If Samantha has at most $75 for her day at the spa and she plans to spend $32 on a haircut and $26 on a manicure, we can calculate the maximum amount she would have left over by subtracting the cost of the haircut and manicure from her total budget. The equation we use for this calculation is:
Total Budget - (Cost of Haircut + Cost of Manicure) = Money Left Over
Let's do the math:
$75 - ($32 + $26) = $75 - $58 = $17
So, Samantha will have a maximum of $17 left after she pays for her haircut and manicure.
In the process of proving that opposite sides of a parallelogram are congruent, Ross drew a diagonal of the parallelogram and determined that the two triangles formed are congruent. He then concluded that opposite sides must be congruent, because corresponding parts of congruent triangles are congruent.
Using his markings in the diagram, which postulate allowed him to determine that the two triangles formed are congruent?
