Answer:
k^2 -3k +9/2
(k-3/2)^2
Step-by-step explanation:
k^2 -3k
Take b/2 and then square it to find the term to complete the square
(-3/2) ^2 = 9/4
k^2 -3k +9/2
The expression factors to (k-b/2)^2
(k-3/2)^2

Topic: Applying Systems of Equations
Define your variables:
At Manny's taco shop, you can get an order of chips and two tacos for $9.25. The cost for two orders of chips and five tacos is $21.75.
x = Chipsy = TacosWrite your system of Equations:You can get an order of chips and two tacos for $9.25.
1 Chips + 2 Tacos = 9.25
x + 2y = 9.25The cost for two orders of chips and five tacos is $21.75.
2 Chips + 5 Tacos = 21.75
2x + 5y = 21.75Solve The System:First equate the coefficient - in this case x:
(x + 2y = 9.25) * 2 = 2x + 4y = 18.50
2x + 4y = 18.50
2x + 5y = 21.75
Minus the equations from each other to remove the coefficient you equated:
(2x + 5y) - (2x + 4y) = 21.75 - 18.50
(2x - 2x) + (5y - 4y) = 21.75 - 18.50
y = 3.25Answer The Question Being Asked:What is the cost of an order of chips?1 Taco = $3.25
y = 3.25
Substitute this into the equation.
x + 2y = 9.25
x + (2 * 3.25) = 9.25
x + 6.50 = 9.25
Rearrange to find x:
x = 9.25 - 6.50
x = 2.75
Chips = $2.75

What is the volume of the square pyramid with base edges 12 cm and height 12 cm?
Answer:
V=144

what is the exact volume of the cylinder?
Answer:
54π in³
Step-by-step explanation:
The volume (V) of a cylinder is calculated using the formula
V = πr²h ( r is the radius and h the height )
here r = 3 and h = 6, thus
V = π × 3² × 6 = π × 9 × 6 = 54π in³ ← exact value

For St. Patrick's day, Mrs. G's sixth grade class was given a choice of four different drinks. One quarter of the class chose green milkshakes, one third of the class chose green ginger ale, one eighth of the class chose the green milk and one sixth of the class chose green juice. How many students did not have a drink?
Answer:
1/8 of the number of students
Step-by-step explanation:
1/4 + 1/3 + 1/8 + 1/6 =
= 6/24 + 8/24 + 3/24 + 4/24
= 21/24
= 7/8
7/8 of the class chose drinks.
1 - 7/8 = 8/8 - 7/8 = 1/8
That means that 1/8 did not have a drink.
Since we don't know the number of students in her class, we cannot tell the number of students who did not have a drink, but we do know it is 1/8 of the number of students.

least to greatest 1 8/35, 1.3, 5/4
Answer:1/3 < 1 8/35 < 5/4
Step-by-step explanation:
Showing Work
Rewriting as fractions if necessary:
43/35, 1/3, 5/4
The least common denominator (LCD) is: 420.
Rewriting as equivalent fractions with the LCD:
516/420, 140/420, 525/420
Ordering these fractions by the numerator in order from least to greatest:
140/420 < 516/420 < 525/420
Therefore, your input in order from least to greatest is:
1/3 < 1 8/35 < 5/4
Television sizes are determined by the length of their diagonal measure. Michael just bought a new television. The height of the television is 40 inches and the length is 71.5 inches. Using the Pythagorean Theorem, what is the size of Michael’s new television? Round your answer to the nearest whole inch (whole number).
Part A: What parts of the right triangle have you been given? Are you looking for a leg or the hypotenuse? The legs have already been given. I’m looking for the hypotenuse.
Part B: Set-up your equation by substituting the correct numbers in to the formula.
71.5^2+40^2=c^2

PART A AND B ARE DONE ALREADY
I WILL GIVE BRAINLIEST TO THE CORRECT ANSWER.
Answer:
Part A) The legs have already been given. I’m looking for the hypotenuse
Part B) [tex]c^{2}=40^{2} +71.5^{2}[/tex]
Part C) The missing length is [tex]81.93\ in[/tex]
Part D) [tex]82\ in[/tex]
Step-by-step explanation:
Part A) What parts of the right triangle have you been given? Are you looking for a leg or the hypotenuse?
we know that
Applying the Pythagoras Theorem
[tex]c^{2}=a^{2} +b^{2}[/tex]
where
c ----> is the hypotenuse of the right triangle
a and b -------> are the legs of the right triangle
In this problem we have
[tex]a=40\ in[/tex]
[tex]b=71.5\ in[/tex]
so
The legs have already been given. I’m looking for the hypotenuse
Part B) Set-up your equation by substituting the correct numbers in to the formula
we have
[tex]a=40\ in[/tex]
[tex]b=71.5\ in[/tex]
substitute in the Pythagoras Theorem and solve for c (hypotenuse)
[tex]c^{2}=40^{2} +71.5^{2}[/tex]
Part C) Solve for the missing length
we have
[tex]c^{2}=40^{2} +71.5^{2}[/tex]
solve for c
[tex]c^{2}=1,600 +5,112.25[/tex]
[tex]c^{2}=6,712.25[/tex]
[tex]c=\sqrt{6,712.25}\ in[/tex]
[tex]c=81.93\ in[/tex]
Part D) What is the size of the television rounded to the nearest whole inch (whole number)?
[tex]81.93=82\ in[/tex]
The Pythagorean Theorem is used to find the size of the TV, which is the hypotenuse in this scenario and equals to approximately 82 inches when rounded to the nearest whole inch.
Explanation:Since we've set up our equation as 71.5^2+40^2=c^2, we can now simply solve for c, which is our hypotenuse, and in this case, represents the size of the television.
To do so, calculate the square of both given sides and add them: (71.5)^2 + (40)^2 = 5112.25 + 1600 = 6712.25.
The next step is to take the square root of that sum to get the length of the hypotenuse/c: sqrt(6712.25) = ~81.94 inches
Part D: Now, to answer the final part of your question, if we round this result to the nearest whole inch, we get 82 inches as the size of the new television.

What is the volume of the following rectangular prism?
Answer:
The volume of the rectangular prism is [tex]8\frac{1}{2}\ units^{3}[/tex]
Step-by-step explanation:
we know that
The Volume of a rectangular prism is equal to
[tex]V=BL[/tex]
where
B is the area of the base
L is the length of the prism
In this problem we have
[tex]B=2\frac{1}{8}\ units^{2}=\frac{8*2+1}{8}=\frac{17}{8}\ units^{2}[/tex]
[tex]L=4\ units[/tex]

3. The triangle will be dilated by a scale factor of 2.5.
(a) What is the length of each of the sides after the dilation?
(b) Draw the new image and label it .
Answer:
Part a) The length of each of the sides after the dilation is
[tex]A'B'=30\ units[/tex]
[tex]B'C'=25\ units[/tex]
[tex]A'C'=35\ units[/tex]
Part b) The graph in the attached figure
Step-by-step explanation:
Part a) What is the length of each of the sides after the dilation?
In this problem we have that the scale factor is 2.5
The scale factor is greater than 1
so
The dilation is an enlargement
To find the length of each of the sides after the dilation, multiply the original length by the scale factor
so
[tex]A'B'=AB*2.5=12*2.5=30\ units[/tex]
[tex]B'C'=BC*2.5=10*2.5=25\ units[/tex]
[tex]A'C'=AC*2.5=14*2.5=35\ units[/tex]
