Answer:
$3.039
Step-by-step explanation:
Step 1
They bought 2 pounds of paper hearts at $ 3.42 per pound
1 pound = $3.42
2 pounds =
2 × $3.42
= $6.84
2 pounds of sparkling stars for $ 3.93 per pound
1 pound of sparking stars = $3.93
2 pounds =
$3.93 × 2
= $7.86
5 pounds of shiny coils for $ 2.53 per pound.
1 pounds of shiny coils = $2.53
5 pounds =
5 × $2.53
= $12.65
Step 2
We find the total cost of the materials
Total cost of Materials that make up the confetti = Cost of paper heart + Cost of sparkling stars + Cost of shiny coils.
= $6.84 + $7.86 + $12.65
= $27.35
Step 3
Total pounds of materials bought = 2 pounds + 2 pounds + 5 pounds
= 9 pounds
Step 4
The cost per pound of confetti = Total cost of the materials bought/ Total pounds of materials
= $27.35/9
= $3.0388888889
Approximately ≈ $3.039
The cost per pound of the confetti = $3.039
The cost per pound of the confetti is $3.04
Total cost :Given that, they bought 2 pounds of paper hearts at $ 3.42 per pound.
The cost of 2 pounds of paper hearts is, [tex]=2 *3.42=6.84[/tex]
the 2 pounds of sparkling stars for $ 3.93 per pound
The cost of 2 pounds of sparkling stars is, [tex]=$3.93 * 2=7.86[/tex]
the 5 pounds of shiny coils for $ 2.53 per pound.
The cost of 5 pounds of shiny coils is, [tex]=5 * $2.53=12.65[/tex]
Total cost of confetti is,
[tex]= $6.84 + $7.86 + $12.65=27.35[/tex]
Total pounds of materials bought ,
[tex]=2+2+5=9pounds[/tex]
The cost per pound of confetti is,
[tex]=\frac{27.35}{9}=3.04[/tex]
The cost per pound of the confetti is $3.039

The endpoints of CD are C (4,6) and D(-1,-1). Find the coordinates of the midpoint M.
Coordinates of midpoint M: OD
6 HELP ME PLEASE I REALLY NEED HELP FAST 30 points
Answer:
M = (1.5, 2.5 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]
Here (x₁, y₁ ) = C(4, 6) and (x₂, y₂ ) = D(- 1, - 1) , thus
midpoint = [ [tex]\frac{1}{2}[/tex] (4 - 1) , [tex]\frac{1}{2}[/tex] (6 - 1 ) ] = (0.5(3), 0.5(5) ) = (1.5, 2.5 )
Write an equation of the parabola in vertex form.
Answer:
f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. ... When written in "vertex form": • (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.
Answer:
y =0.25(x-4 )^{2}-1
Step-by-step explanation:
The formula of vertex form is as follows:
Y = a(x-h)^2+k
h = the x value for the vertex (in this case it is 4)
k = the y value for the vertex (in this case it is -1)
If you input these into the equation you are left with:
Y = a(x-4)^2-1
To find 'a' I just entered this equation into the Desmos calculator and messed around with the value until the y-intercept was (8,3)
I hope this was able to help! ^_^

HELPPP PLEASEEEE I NEED THE ANSER Select the most precise and correct definition of parallel lines from among those that are given. Choose 1 answer: (Choice A) A Two distinct lines are parallel if one can be rotated to sit on top of the other. (Choice B) B Two distinct lines are parallel if they point in the same direction. (Choice C) C Two distinct lines are parallel if they are in the same plane and never intersect each other.
Answer:
C. Two distinct lines are parallel if they are in the same plane and never intersect each other.
Step-by-step explanation:
Parallel lines are best defined as 2 different lines that are in the same plane and will never intersect each other at any point in the graph.
They are always the same distance apart and will never touch.
So, C is correct
Answer:
C
Step-by-step explanation:
The very definition of parallel lines is that they have the same slope, if they have the same slope, they will never meet.
What is the opposite value of -(-9) ?
Answer:
9
Step-by-step explanation:
two negatives make a positve
Answer:
-9
Step-by-step explanation:
Whenever you are given an expression, first look at it. Since there are two negative signs in the equation, they cancel out, leaving a nine. The opposite value most likely means that the sign is the opposite, so you end up with -9 as the value.

Please solve -21+6x=3(3x-5)-x
Answer:
x=-3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−21+6x=3(3x−5)−x
−21+6x=(3)(3x)+(3)(−5)+−x(Distribute)
−21+6x=9x+−15+−x
6x−21=(9x+−x)+(−15)(Combine Like Terms)
6x−21=8x+−15
6x−21=8x−15
Step 2: Subtract 8x from both sides.
6x−21−8x=8x−15−8x
−2x−21=−15
Step 3: Add 21 to both sides.
−2x−21+21=−15+21
−2x=6
Step 4: Divide both sides by -2.

Function h is a transformation of the parent exponential function, f(x)=2^x. h(x)=-3*2^x Which statement is true?
A. Function h is a vertical translation of function f. B. Function h is a reflection and a dilation of function f. C. Function h is a reflection and a translation of function f. D. Function h is a horizontal translation of function f.
Answer:
Function is a reflection and dilation of function f.
Step-by-step explanation:
A reflection gives the mirror image of function.
A function can be reflected about an axis by multiplying by -1.
To reflect function about the x-axis, multiply f(x) by -1 to get -f(x).
The correct option is: B. Function h is a reflection and a dilation of function f.
-----------------------
The functions are:
[tex]f(x) = 2^x[/tex]
[tex]g(x) = -3 \times 2^x[/tex]
It can be seed that g is f multiplied by -3.
The multiplication by a constant means that a dilation happened.Since the constant is negative, it means that a reflection also happened.In the image at the end of this question, it can be seen that the g, the blue graph, is a reflected and dilated version of f, the red graph.
Thus, the correct answer is:
B. Function h is a reflection and a dilation of function f.

Lcm of 4 and 15?
least common multiple
=================================================
Explanation:
Multiply the two values to get 4*15 = 60
Then divide by the GCF 1 to get 60/1 = 60. The GCF being 1 means the result hasn't changed.

Another example would be: "Find the LCM of 6 and 8". We would first do 6*8 = 48, then divide by the GCF 2 to get 48/2 = 24. The LCM of 6 and 8 is 24.
