A. Subtract $1.00 off each bag and then multiply by .20
B. Multiply each bag by .20, subtract $1.00 off of each bag, and then add them together.
C. Add the two bags together, multiply by .80, and then subtract $1.00.
D. Subtract $1.00 from the first bag, then add them together, and then multiply by .80.
Answers
Answer:
The correct option is: C. Add the two bags together, multiply by .80, and then subtract $1.00.
Step-by-step explanation:
First you need to add the prices of two bags for getting the total sales price.
Now, the store is offering 20% off, that means you need to pay 80% of the total sales price. For finding the amount, we need to multiply the total sales price by 0.80
Then, you have a manufacturers coupon for a $1.00 off. So, for fining the final price, you need to subtract that $1.00 from the last result.
Thus, the correct option will be......
C. Add the two bags together, multiply by .80, and then subtract $1.00.

The radius of a cylindrical water tank is 5.5ft, and its height is 8ft
. What is the volume of the tank? Use the value 3.14 for π, and round your answer to the nearest whole number.Be sure to include the correct unit in your answer.
Answers
The volume of the cylindrical water tank with a radius of 5.5 feet and a height of 8 feet is 760 cubic feet after rounding to the nearest whole number.
To calculate the volume of a cylindrical water tank, we use the formula V = , where V represents volume, is the constant Pi, approximately equal to 3.14, r is the radius of the cylinder, and h is its height.
Given that the radius r is 5.5 feet and the height h is 8 feet, substituting these values into the formula gives us:
V = 3.14 * (5.5ft) * 8ft
First calculate the radius squared:
5.5ft * 5.5ft = 30.25ft
Now, calculate the volume:
V = 3.14 * 30.25ft * 8ft = 3.14 * 242ft = 759.88ft
After rounding to the nearest whole number, the volume is 760 cubic feet.
You have been asked by the police department to find three locations the Acute Perps gang is likely to hit in the coming weeks. Because the gang sticks to a triangular pattern, the locations could be a translation, reflection, or rotation of the original triangle. For this step, identify and label three points on the coordinate plane that are a translation of the original triangle. Next, use the coordinates of your translation along with the distance formula to show that the two triangles are congruent by the SSS postulate. You must show all work with the distance formula.
Answers
Note:
Images with coordinates or original and translated triangles are attached.
Answer:
The coordinates for the given triangle are A(6,3), B(6,-3) and C(-2,-3), respectively.
Let us translate this triangle by -6 units along the x-axis and +3 units along the y-axis. This means that 6 will be subtracted from each of the abcissas (x-points) and 3 will be added to each ordinates (y-points). Hence, our translated triangle will have the following coordinates: A'(0,6), B'(0,0) and C'(-8,0), respectively.
Now to prove that both triangles are congruent, we use the SSS postulate, which states that:
"If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent."
Distance between two point P1 and P2 will be:
[tex]|P_1P_2|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Now using distance formula to find sides of triangle ABC and triangle A'B'C'.
For Triangle ABC:
|AB| = [tex]\sqrt{(6-6)^2+(-3-3)^2} =\;6\;units[/tex]
|AC| = [tex]\sqrt{(-2-6)^2+(-3-3)^2} =\;10\;units[/tex]
|BC| = [tex]\sqrt{(-2-6)^2+[-3-(-3)]^2} =\;8\;units[/tex]
For Triangle A'B'C':
|A'B'| = [tex]\sqrt{(0-0)^2+(0-6)^2} =\;6\;units[/tex]
|A'C'| = [tex]\sqrt{(-8-0)^2+(0-6)^2} =\;10\;units[/tex]
|B'C'| = [tex]\sqrt{(-8-0)^2+(0-0)^2} =\;8\;units[/tex]
Hence, as the distances are equal, the two triangles are congruent by SSS postulate.

find m KTL. Please I need help
Answers
___________________________
Given: m∡3 = m∡4 = 123° ;
Since the sum of ALL ANGLES in ANY TRIANGLE equal 180°;
→ the m∡ KTL = 180 − ( m∡ KLT + m∡TKL)
We want to find
1) m∡ KLT ; AND:
2) m∡ TKL ,'
_____________
{Note: Alternatively, "m∡ KLT" can be written as: "m∡ TLK" ; and:
"m∡ TKL" can be written as: "m∡ LKT" . }.
________________________________________________
Since the sum of ALL ANGLES in ANY TRIANGLE equal 180;
→ m∡ KTL = 180 − ( m∡ KLT + m∡TKL) ;
___________________________________________
Or: → m∡ KTL = 180 − m∡ KLT − m∡TKL ;
Since, the distributive property of multiplication states:
________________________________
→ a* (b + c) = ab + ac ; AND
→ a *(b − c) = ab − ac
______________________________
Thus: m∡ KTL = 180 − ( m∡ KLT + m∡TKL) =
→ 180 − 1( m∡ KLT + m∡TKL ) ;
_____________________________________
→Note: The invisible "1" is implied, since anything multiplied by "1" equals that same value. We treat this as "-1" (negative one), due to the "minus sign).
_______________________________________
→ -1 * ( m∡ KLT + m∡ TKL ) =
→ -1 * (1 m∡ KLT + 1 m∡TKL ) =
→ (-1 * 1 m∡ KLT) + ( -1 * 1 m∡TKL ) =
→ (-1 m∡ KLT) + ( -1 m∡TKL) =
→ -1 m∡ KLT − 1 m∡TKL ;
_________________________________
Now, bring down the "180" and rewrite:
_____________________________________
→ 180 − 1 m∡ KLT − 1 m∡TKL ; → Delete the "ones" ; and Rewrite:
__________________________________________
→ 180 − m∡ KLT − m∡TKL ;
_______________________
→ m∡ KTL = 180 − m∡ KLT − m∡TKL = 180 − (m∡ KLT + m∡TKL) ;
__________________________________________________________
→Now, solve for: m∡ KLT ;
_____________________________
→Using the diagram; m∡ KLT = 180 − m∡4 ; Given m∡4 = 123; and
∡4 and ∡KLT are supplementary angles [the only two (2) angles on a particular straight line]; the sum of m∡4 and m∡KLT = 180.
→ m∡ KLT = 180 − m∡4 = 180 − 123 = 57 .
_____________________________________________
→Now, solve for: m∡TKL ;
______________________________
→Using the diagram; m∡ TKL = 180 − m∡3 ; Given m∡3 = 123; and
∡3 and ∡TKL are supplementary angles [the only two (2) angles on a particular straight line]; the sum of m∡3 and m∡KLT = 180.
→ m∡ KLT = 180 − m∡4 = 180 − 123 = 57
______________________________________________
→So, in our "triangle": ΔKTL; we want to find the m∡T; that is m∡KTL;
____________________________________________
We know that each of the other 2 (two) angles in this triangles measures 57° .
______________
So, we calculate as follows:
____________________________
Method 1:
___________
m∡ KTL = 180 − ( m∡ KLT + m∡TKL)
= 180 − ( 57 + 57) = 66° .
___________________________________________
Or: Method 2:
___________________________________________
m∡ KTL = 180 − ( m∡ KLT + m∡TKL)
= 180 − ( 57 + 57)
= 180 − (57 * 2) = 180 − 114 = 66° .
________________________________________
Or: Method 3:
_________________________
→ m∡ KTL = 180 − m∡ KLT − m∡TKL
= 180 − 57 − 57 = 66° .
______________________________________________________
Answer: m∡ KTL = 66° .
_______________________________________________________
→ Let us check our answer to see if it "makes sense":

Which of the following statements are true of a transversal?
It is a line.
It is parallel to other coplanar lines.
It intersects two or more coplanar lines.
It bisects line segments.
It can be perpendicular to other lines.
Answers
Definition: A transversal is a line that crosses at least two other lines.
Main properties:
It is a line (A is true).It is not parallel to other coplanar lines, because it crosses them (B is false).It intersects two or more coplanar lines (C is true).It bisects line segments (D is false).It can be perpendicular to other lines, it can be perpendicular to lines which it crosses (E is true).Answer: true are options A, C and E.
A transversal in Mathematics is a line that intersects two or more lines at different points, but does not necessarily have to be parallel or bisect these lines. It can, however, be perpendicular to them.
Explanation:In the subject of Mathematics, a transversal refers to a line that intersects two or more coplanar lines at different points. Therefore, the statement 'It is a line' and 'It intersects two or more coplanar lines' are true for a transversal.
The term transversal doesn't necessitate that it be parallel to other coplanar lines, nor does it indicate that it bisects line segments, so these statements are false. However, a transversal can be perpendicular to other lines if it intersects them at 90-degree angles.

After a certain number of moves in a chess game, the ratio of black pieces to white pieces is 4 to 3. If there are 12 black pieces on the board, which proportion can be used to find the number of white pieces?
Answers
To find the number of white pieces when the ratio of black pieces to white pieces is known, set up a proportion and solve for the missing variable. In this case, the number of white pieces is 9.
To find the number of white pieces, we can use the proportion 3/4 = W/12, where W represents the number of white pieces.
Cross multiply to get 3*12 = 4*W
Therefore, 36 = 4W
Divide by 4 to find that W = 9.

What is the axis of symmetry of the function f(x) =-(x+9)(x-21)
Answers
Manipulating algebrically,
We get,
f(x) =-(x+9)(x-21)
= -(x^2 -21x + 9x - 189)
= -(x^2 -12x - 189)
= -x^2 + 12x + 189
Axis of symmetry = -b/2a
plugging the values,
x = -12/-2
= 6
Answer:
x = 6
Step-by-step explanation:
The given equation is [tex]f(x)=-(x+9)(x-21)[/tex]
We write the equation in standard form of parabola [tex]f(x)=ax^2+bx+c[/tex] using FOIL
[tex]f(x)=-(x+9)(x-21)\\\\f(x)=-(x^2-21x+9x-189)\\\\f(x)=-x^2+12x+189[/tex]
Now, we know that the axis of symmetry passes through the vertex. Hence, in order to find the vertex of the parabola, we find the x coordinate of the vertex.
x coordinate of the vertex is [tex]-\frac{b}{2a}[/tex]
Here, a = -1 b = 12
[tex]-\frac{b}{2a}\\\\=-\frac{12}{2\cdot(-1)}\\\\=-(-6)\\\\=6[/tex]
Therefore, the axis of symmetry is x = 6
