Answer:
The statements that are true
A.) Six of the one half cubes would have a volume of 3 cubic units.
D.) Three of the one-third cubes will make 1 unit cube.

F. Both stacks will have a volume of 3 cubic units.
Step-by-step explanation:
Complete, Correct Question
Marissa claims that stacking 6 blocks with dimensions of (½×1×1) will give the same volume as stacking 9 blocks with
dimensions of [(1/3)×1×1] Which statements about her claim are true? Check all that apply.
Before checking the statements, we first find the volume of both cars of blocks
Volume of a cuboid block = lbh
For block A, volume = (1/2) × 1 × 1 = (1/2) cubic units
6 block A's will have a volume of 6 × (1/2) = 3 cubic units.
For block B, volume = (1/3) × 1 × 1 = (1/3) cubic units
9 block B's will have a volume of 9 × (1/3) = 3 cubic units.
Now checking the statements one at a time
A. Six of the one half cubes would have a volume of 3 cubic units.
As calculated above, this is true.
B. Nine of the one-third cubes would have a volume of 6 cubic units.
This is false. 9 of the one-tailed cubes has a volume of 3 cubic units too not 6 cubic units.
C. Since 1/2 and 1/3 do not have common factors, stacks of one-half cubes and stacks of the two cubes could never have the same volume.
From the calculation before analysing the statements, the two stacks mentioned had the same total volume of 3 cubic units. Hence, it shows this statement is false.
D. Three of the one-third cubes will make 1 unit cube.
3 one-third cubes will have a volume of
3 × (1/3) = 1 cubic unit. This statement is true.
E. Two of the one-half cubes will make 1 unit cube.
2 one-half cubes will have a volume of
2 × (1/2) = 1 cubic unit. This statement is true.
F. Both stacks will have a volume of 3 cubic units.
From previous calculation before analysing the statements one at a time, this is true. The total volume of both stacks mentioned today is 3 cubic units.

Answer:
g(n) = [tex]\frac{11+5n}{3}[/tex]
Step-by-step explanation:
Given
3m - 5n = 11
Rearrange making m the subject
Add 5n to both sides
3m = 11 + 5n ( divide both sides by 3 )
m = [tex]\frac{11+5n}{3}[/tex] , thus
m = g(n) = [tex]\frac{11+5n}{3}[/tex]

4(x + 6) = 32 What is x?
Answer: x = 2
Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.
So we have 4(x) which is 4x and 4(6) which is 24.
So our equation now reads 4x + 24 = 32.
Solving from here, we subtract 24 from both sides to get 4x = 8.
Then divide both sides by 4 to get x = 2.

Which net matches the figure?
In the first image, notice that the figure is a cube
also known as a "square prism."
Since a cube is composed of square bases, we
want to find a net that is composed of all squares.
Notice that the option of the bottom left is composed of squares.
So this net matches the figure.

Answer:
254.34 cm^2
Step-by-step explanation:
Volume of cylinder = [tex]\pi r^{2} h[/tex]
We know that the diameter is 6, which means that the radius is 3 cm.
Now, it also tell us that that the height is triple the radius, this means that we multiply it by 3. Therefore, the height is 9 cm.
Now we know r = 3 cm and h = 9 cm, pi is assumed to 3.14 as well.
Substituting into the formula we will end up with 254.34 cm^2.
please answer this ASAP
Answer:
Step-by-step explanation:
Area of circle = πr² = 15 m²
Volume of Cylinder = πr²h

= 45 m³
Volume of Cone = (1/3)πr²h
[tex]=\frac{1}{3}*15*3\\\\[/tex]

Use the Pythagorean Theorem to determine if a triangle with sides 15 cm, 7 cm, and 16 cm is a right triangle.
Answer:
It is not.
Step-by-step explanation:
[tex]15^{2}[/tex]+[tex]7^{2}[/tex]=225+49=274
[tex]16^{2}[/tex]=256
274≠256
Answer:
No, this triangle is not a right triangle
Step-by-step explanation:
If (7 cm)^2 + (15 cm)^2 = (16 cm)^2, then this is a right triangle, by the Pythagorean Theorem. Otherwise it is not.
15^2 + 7^2 = 225 + 49 = 1225 = 35^2. This is FALSE, and so:
No, this triangle is not a right triangle

Answer:
x > 0
Step-by-step explanation:
Division by zero is not defined. Therefore, x must be greater than zero. Also: The square root function is defined only for x greater than zero or equal to zero. Together these restrictions tell us that the domain is (0, infinity ).
On a coordinate plane, trapezoid A B C D has points (negative 3, negative 2), (negative 1, 2), (3, 2), and (5, negative 2). Trapezoid ABCD is graphed in a coordinate plane. What is the area of the trapezoid? 16 square units 24 square units 32 square units 48 square units
Answer:
Correct option: second one -> 24 square units
Step-by-step explanation:
First we need to find the length of each side of the trapezoid, and we do that finding the distance between points:
AB = sqrt( (-1 - (-3))^2 + (2 - (-2))^2) = 4.4721
BC = sqrt( (3 - (-1))^2 + (2 - 2)^2) = 4
CD = sqrt( (5 - 3)^2 + (-2 - 2)^2) = 4.4721
DA = sqrt( (-3 - 5)^2 + (-2 - (-2))^2) = 8
The points B and C have the same y-coordinate, and the points D and A also have the same y-coordinate, so they are the bases of the trapezoid.
The height of the trapezoid is the difference in y-coordinate of points B and A:
height = 2 - (-2) = 4
So the area of the trapezoid is:
Area = (BC + DA) * 4 / 2 = (4 + 8) * 2 = 24 square units
Correct option: second one
Answer:
Its B

find the value of JW given that JW=6x+2 and JB=10x+1
The value of JW is 14 units.
What is a triangle?A triangle is a polygon with 3 sides. The area of a triangle with base b and height h is given by A = (1/2)bh.
Given that, JB is the median of the triangle and JW = 6x + 2 and JB = 10x + 1.
The distance between the centroid and a vertex of a triangle is 2/3 of the length of the median, therefore, it follows:
JW = (2/3)JB
Substitute the values:
6x + 2 = (2/3)(10x + 1)
18x + 6 = 20x + 2
2x = 4
x = 2
Substitute x = 2 into the expression for JW:
JW = 6(2) + 2
JW = 14
Hence, the value of JW is 14 units.
