Answer:
9840
Step-by-step explanation:
Cubic centimeters used in final wood sculpture = volume of rectangular prism minus volume of triangular prism
To find the volume of a rectangular prism simply multiply the width by the length by the height
The rectangular prism has a given width of 20cm, a given height of 30cm and a given length of 20cm
So volume of rectangular prism = 20 * 20 * 30 = 12,000
Now let's find the volume of the triangular prism she cut out.
To find the volume of a triangular prism we can use this formula
V = bh/2 * l
Where b = base length, h = height of base and l = length of prism
The triangular prism has a given base length of 12cm a given height of 12cm and a given length of 30cm ( we can tell by looking at the image the length of the triangular prism is the same as the height of the rectangular prism.)
We then plug in these dimensions into the formula
V = (12*12)/2 * 30
12 x 12 = 144
144/2 = 72
72 * 30 = 2160
Finally we subtract the volumes
12,000 - 2160 = 9840
We can conclude that the volume of the final sculpture is 9840 cubic centimeters

Solve the system of equations below by elimination. Write your answer as an ordered pair. e.g. (2,3)
Answers
Answer:
(45,35)
Step-by-step explanation:
1 - Stack the equations on top of each other
3x - 4y = -5
4x + 4y = 40
2 - We can eliminate by subtracting the bottom equation from the top equation
3x - 4y = -5
- 4x - 4y = 40
3 - The y's cancel out, leaving us with...
3x = -5
- 4x = 40
4 - Continue simplifying
-1x = -45
5 - We can switch the -1x with -x to make things simple
-x = -45
6 - Positize (make it positive) the statement
x = 45
7 - Halfway there! Substitute the x value into one of the equations
(3 * 45) - 4y = -5
8 - Solve
135 - 4y = -5
Minus 135 on both sides
-4y = -140
Divide by -4 on both sides
y = 35
9 - Here is your answer!!
x = 45
y = 35

At the Manchester Ice Cream Parlor, one group of friends ordered 1 small serving of ice cream and 1 large serving of ice cream for $5. Another group of friends ordered 4 small servings of ice cream and 5 large servings of ice cream for $24. How much does the ice cream cost?
The ice cream costs $__ for a small serving and $__ for a large serving.`
Answers
small is $1
Answer:
$24
Step-by-step explanation:
5 large servings = 4 + 4 + 4 + 4 + 4 = $20
4 small servings = 1 + 1 + 1 + 1 = $4
20 + 4 = $24
The ice cream costs $1 for a small serving and $4 for a large serving.

The formula to find out the volume of a rectangular prism is V = l × b × h where V is the volume , l = length , b = breadth & h = height.We're provided the figure of trapezium in the second attachment. The formula to fInd out the area of trapezium is A = [tex] \tt{ \frac{1}{2} h(a + b)}[/tex] where a and b are the opposite parallel sides and h be the height of a trapezium.[tex] \large{ \tt{❃ \: SOLUTION}} : [/tex]
In the first picture , we're provided - Length ( l ) = [tex] \frac{7}{4} [/tex] cm , breadth ( b ) = [tex] \frac{3}{2} [/tex] cm and height ( h ) = [tex] \frac{1}{2} [/tex] cm. Now, plug these known values and them find out the volume of given rectangular prism.[tex] \large{ \tt{❁ \: VOLUME \: OF \: RECTANGULAR \: PRISM \: ( \: V \: ) = l \times b \times h}}[/tex]
[tex] \large{ {⟶ \: \frac{7}{4} \times \frac{3}{2} \times \frac{1}{2} }}[/tex]

V = l * w * h
7/4 * 3/2 * 1/2 = 21/16 cm^3
2)
A = a+b ÷ 2 * h
6 + 4 = 10 ÷ 2 = 5

2/3 a - 1/6 = 1/3
answer this math question asap pls
Answers
Answer:
a=3/4
Step-by-step explanation:
1. Get 2/3a by itself.
•Turn 1/3 to 2/6 by multiplying 1/3 by 2/2.
•Because you only add and subtract like denominators
This will make it look like:
2/3a - 1/6 = 2/6
Then, add 1/6 to both sides to get 2/3a by itself.
It'll look like this:
2/3a = 3/6
2. Get a by itself.
•Multiply the reciprocal (opposite) of 2/3 to get a alone.
This will look like:
(3/2) • 2/3a = (3/2) • 3/6
a = 18/24
3. Simplify.
Find the largest number that can simplify the equation.
For example, 18 ÷ 3 = 6, and 24 ÷ 3 = 8.
But the largest number you can divide both sides by is 6.
18 ÷ 6 = 3 and 24 ÷ 6 = 4.
3/4.
