What is the volume of a rectangular prism with l = 412 cm, w = 312 cm, and h = 6 cm?
Answer:
Step-by-step explanation:
V = l · w · h
V = (412)(312)(6)
V = (1872)(412)= 771,264 cm^3
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{771264 \: \: {cm}^{3} }}}}}[/tex]
Step-by-step explanation:
[tex] \star{ \sf{ \: length \: of \: a \: rectangular \: prism(l) = 412 \: cm}}[/tex]
[tex] \star{ \sf{ \: width \: of \: a \: rectangular \: prism \: ( \: w \: ) = 312 \: cm}}[/tex]
[tex] \star{ \sf{ \: height \: of \: a \: rectangular \: prism \: ( \: h \: ) = 6 \: cm}}[/tex]
Finding the volume of a rectangular prism having length ( l ) of 412 cm , width ( w ) of 312 cm and height ( h ) of 6 cm :
[tex] \bold{\boxed{ \sf{volume \: of \: a \: rectangular \: prism = lwh}}}[/tex]
[tex] \hookrightarrow{ \sf{volume \: of \: a \: rectangular \: prism \: = 412 \times 312 \times 6}}[/tex]
[tex] \hookrightarrow{\boxed{ \sf { volume \: of \: a \: rectangular \: prism = 771264 \: {cm}^{3} }}}[/tex]
Volume of a rectangular prism = 771264 cm³

Determine which of the following statements about rigid transformations is false.
Question 5 options:
In a translation, the segments joining points of the pre-image and their images are perpendicular.
In a reflection, the segments joining points of the pre-image and their images are perpendicular to the line of reflection.
In a rotation, the points of the pre-image are always the same distance away from the center of rotation as the corresponding points of the image.
In a reflection, the points of the pre-image are always the same distance away from the line of reflection as the corresponding points of the image.
Answer:
The false statement about rigid transformation is;
In a translation, the segments joining points of the pre-image and their images are perpendicular
Step-by-step explanation:
The direction of a rigid transformation involving a translation can vary from changes in the values of one of the two coordinates of the vertex points in the figure with the same change value for all the vertices or
The translation can also be made by changing the values of both coordinates of the vertex each coordinate having equal value of change which may be different from the value of change of the other coordinate, maintaining the size of the figure.
In the second case, the translation can be in other directions other than vertical or horizontal, such that, the segments joining the points of the pre-image with the corresponding point on the image are parallel.
The false statement about rigid transformation is;
In a translation, the segments joining points of the pre-image and their images are perpendicular
The direction of rigid transformation:It includes a translation that could be varied from changes in the values of one of the two coordinates of the vertex points having the same change value for all the vertices. The translation could also be made via changing the values of both coordinates of the vertex every coordinate that contains the equal value of change.

Harry and Jenny are going to the movies. They each bought a medium popcorn, and Harry got a small soft drink. Jenny had a $4 coupon as a discount, and Harry paid the rest, which came to $23. A movie ticket costs $8, and a medium popcorn costs $4.50. What was the cost for a soft drink?
Answer:
2$
Step-by-step explanation:
2 medium popcorns = 9$
2 Movie tickets = 16$
One coupon = -4$
This is equal to the cost without the soft drink(21$)
23$ - 21$ = 2$
Answer:
$2
Step-by-step explanation:
It was originally $27 but, Jenny used a $4 coupon. Each movie ticket costs $8, each popcorn cost $4.50.
1. Start from the cost of each item.
8+8=16 (cost of the tickets)4.50+4.50=9 (cost of the popcorn) .2. Add the totals together.
16+9+ 25
Now subtract 25 from the original amount.
27-25=2
It costs 2 dollars for a soft drink.
Here is a system of linear equations:
6x+21y=103
-6x+23y=51
Would you rather use subtraction or addition to solve the system? Explain your reasoning.
Step-by-step explanation:
6x + 21y = 103
-6x + 23y = 51
The signs of the x coefficients are opposite. So adding the equations will eliminate the x terms.
44y = 154
y = 3.5
Combining the equations will remove the x terms because the x coefficients have inverse signs. The solution to the given system of linear equations is x = 4.92 and y = 3.5.
What is the equation?The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.
Here is a system of linear equations:
⇒ 6x + 21y = 103
⇒ -6x + 23y = 51
Inverse signs can be seen in the x coefficients. The x terms will therefore be removed after adding the equations.
⇒ 44y = 154
⇒ y = 3.5
Substitute the value of y = 3.5 in the equation 6x + 21y = 103
⇒ 6x + 21(3.5) = 103
⇒ 6x + 73.50 = 103
⇒ 6x = 103 - 73.50
⇒ 6x = 29.50
⇒ x = 4.92

W/-4 + 17=9. Solve for w what is w
Answer:
w=-32
Step-by-step explanation:
Answer: w=32
Step-by-step explanation:
Given
w/-4 + 17=9
Subtract 17 on both sides
w/-4 + 17 - 17=9-17
w/-4=-8
Multiply -4 on both sides

tells you they will cost $15.50 each, and shipping will cost $12.60
The website then suggests you can save some money by buying a 4th shirt, because
the cost per shirt will reduce to $14.00 each, AND shipping will be free.
How much money will you save by buying 4 T-Shirts?
Your answer will be a positive decimal value. You do NOT NEED the $ sign.
Answer:You will be saving $3.10
Answer:
Step-by-step explanation:
3 T-Shirts price= 15.50
mean 1 T-Shirt price=5.16
3 T-Shirts shipping=12.60
mean 1 T-Shirt Shipping=4.2
If I get 4 then
4 T-Shirts price will be 5.16 x 4 = 20.65

for line segment ac, point b is between points a and c. points abc are collinear. if ab=x-7, bc=2x-2, and ac=x+13. solve for bc
Answer:
BC = 20Step-by-step explanation:
Point B is between points A and C and points A, B, C are collinear so
AB + BC = AC
x-7 + 2x-2 = x + 13
3x - 9 = x + 13
+9 +9
3x = x + 22
- x - x
2x = 22
BC = 2x - 2 = 22 - 2 = 20

Julio is payed 1.2 times his normal hourly rate for each hour he works over 30 hours in a week. Last week he worked 40 hours and earned $495.60 enter and solve an equation to find julios hourly rate, r. Complete the explanation how you know that your answer is reasonable
Answer: $10.33
Step-by-step explanation:
Given: Julio is payed 1.2 times his normal hourly rate for each hour he works over 30 hours in a week.
Last week he worked 40 hours ( > 30 hours by 10 ) and earned $495.60.
Let r = Julio's hourly rate
if he worked over 30 hours in a week, then hourly rate = 1.2r
According to the question
[tex](1.2r)\times 40=495.60\\\\\Rightarrow\ r=\dfrac{495.60}{1.2\times 40}\\\\\Rightarrow\ r=10.325\approx10.33[/tex]
Hence, his hourly rate = $10.33

The sum of 2/3 + (-1/3) in fraction form is 1/3 after applying the arithmetic operation, the answer would be 1/3.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
The number expression is:
= 2/3 + (-1/3)
= 2/3 - 1/3
Taking 3 as LCM
After simplification:
= (2 - 1)/3
= 1/3
Thus, the sum of 2/3 + (-1/3) in fraction form is 1/3 after applying the arithmetic operation, the answer would be 1/3.

First of all you cannot substitute x with y, so what u do u make the numbers with the same letters they have,and I put -2x because + & - equals to -(minus) :-
3x-2x+2y+8y= x+10y
I don't add 1 to x coze when x alone stands for 1, I added +10y because both the y equations had + they were positive so I add a +.

Describe the steps of constructing a segment that is TWICE as long as the given segment BD.
Answer:
See below
Step-by-step explanation:
From the segment BD, I will consider the point B as the begin and D as the end of the vector, therefore [tex]\overrightarrow{BD} = \vec{v}[/tex]
Once you want a segment that is twice as long as the given segment, we may say that the magnitude of the vector is
[tex]||2\vec{v} || = \sqrt{(2x)^2 + (2y)^2} = \boxed{ \sqrt{4x^2 + 4y^2} }[/tex]
Note: I'm assuming [tex]\vec{v} \in E^2[/tex], which means the segment is in the plain.
