My brain refuses to work because I can only think of Diagon Alley
Answer:
30 cm
Step-by-step explanation:
1. Given the length, width and tallness discover the volume, surface region and inclining of a rectangular crystal
h, l and w are known; discover V, S and d
V = lwh
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)
2. Given the surface region, length and width discover the tallness, volume and askew of a rectangular crystal
S, l and w are known; discover h, V and d
h = (S - 2lw)/(2l + 2w)
V = lwh
d = √(l2 + w2 + h2)
3. Given the volume, length and width discover the stature, surface territory, and slanting of a rectangular crystal
V, l and w are known; discover h, S and d
h = V/lw
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)
4. Given the inclining, length and width discover the tallness, volume and surface space of a rectangular crystal
d, l and w are known; discover h, V and S
h = √(d2 - l2 - w2)
V = lwh
S = 2(lw + lh + wh)

Read the problem. 10% of the students at Harris Middle School are on the yearbook committee. If 30 students are on the yearbook committee, how many students are at Harris Middle School? Pick the model that represents the problem. How many students are at Harris Middle School?
Answer:
100%
300 students
Step-by-step explanation:
let b = number of students in the school
this equation can be derived = 10% x b = 30
to find b, divide both sides of the equation by 10%
b = 30/0.1 = 300
we want find the total number of students in the school, which is equal to 100%

How many 2-liter bottles of soda will you need to fill ten 500 milliliter containers?
Answer:
2.5 bottles
Step-by-step explanation:
10 * 500 ml = 5000 ml
5000 ml = 5 l
5/2 = 2.5
2-liter bottles of soda will need 2.5 bottles to fill ten 500 milliliter containers.
How many milliliters in 1 liter?A liter is a cubic meter unit of volume which is equal to 1000 cubic centimeters.
1 liter = 1000 milliliters
Ten 500 milliliter containers
10 × 500 ml = 5000 ml
5000 ml = 5 l
2-liter bottles of soda will you need
5/2 = 2.5bottles
Therefore, 2-liter bottles of soda will need 2.5 bottles to fill ten 500 milliliter containers.

Given:
Length of the cuboid tank = 4 m
Breadth = 2.5 m
Height = 2.4 m
One third of the tank is filled with water.
1 cubic meter = 1000 liters.
To find:
The quantity of the water in the tank.
Solution:
Volume of a cuboid is:
[tex]V=l\times b\times h[/tex]
Where, l is length, b is breadth and h is the height.
The volume of the tank is :
[tex]V=4\times 2.5\times 2.4[/tex]
[tex]V=24[/tex]
Volume of tank is 24 cubic meter.
One third of the tank is filled with water. So, the volume of the water is
[tex]\dfrac{24}{3}=8[/tex]
The volume of water is 8 cubic meters.
We have,
1 cubic meter = 1000 liters.
8 cubic meter = 8000 liters.
Therefore, the quantity of the water in the tank is 8000 liters.

[tex] \underline{ \underline{ \bf{Question}}}: [/tex] In the given figure , ABC is a triangle in which AB = AC. Also a circle passing through B and C intersects the sides AB and AC at the points D and E respectively. Prove that AD = AE.
~Thanks in advance! :)
Answer:
See Below.
Step-by-step explanation:
We are given that ABC is a triangle in which AB = AC.
A circle passing through B and C also intersects the sides AB and AC at points D and E respectively.
And we want to prove that AD = AE.
By the secant-secant theorem (shown below), we know that:
[tex]AD(AB)=AE(AC)[/tex]
We are given that AB = AC. So, by substitution:
[tex]AD(AB)=AE(AB)[/tex]
And by dividing both sides by AB (AB ≠ 0), we acquire:
[tex]AD=AE[/tex]

3/12 x 6 with explanation!
Answer:
24 is the ans...................
Answer:
1 1/2
Step-by-step explanation:
3/12 * 6
6 is simply 6/1 so
3/12*6/1
multiply from side to side so
3*6=18
and
12*1=12
18/12
simplify to a mixed number
18 goes in 12 once with a remainder of 6, or 18-12=6 so
1 6/12
6/12 can both be simplified by 6 so you divide both by 6
6/6=1 and 12/6=2
1/2
add it back to the whole number

Anyone know answer ???
Answer:
C
Step-by-step explanation:
We know that ∠ 1 + ∠ 2 + ∠3 = 180 → (1)
and ∠ 3 + ∠ 4 = 180 → (2)
From (2) ∠ 3 = 180 - ∠ 4
Substitute ∠ 3 = 180 - ∠ 4 into (1)
∠ 1 + ∠ 2 + 180 - ∠ 4 = 180 ( add ∠ 4 to both sides )
∠ 1 + ∠ 2 + 180 = 180 + ∠ 4 ( subtract 180 from both sides )
∠ 1 + ∠ 2 = ∠ 4 → C
For which of the following is x = -5 a solution? Select all that apply.
Answer:
Options 2, 3, 4, 5 are the solutions.
Step-by-step explanation:
Option 1).
x + 10 = -5
x = -10 - 5
x = -15
Therefore, x = -5 is not the solution.
Option 2).
-x² + 50 = 25
-x² = 25 - 50
-x² = -25
x² = 25
x = ±5
Therefore, x = -5 is a solution
Option (3)
|2x| = 10
2x = ± 10
x = ± 5
Therefore, x = -5 is a solution.
Option (4)
x < 0
Since, -5 < 0
Therefore, x = -5 is a solution.
Option (5)
2x < 10
x < 5
Since, -5 < 5
Therefore, x = -5 is a solution.
Options 2, 3, 4, 5 are the solutions.

Answer:
384 cm^2
Step-by-step explanation:
A = 6a^2 (a = side length)
A = 6(8^2)
A = 6(64)
A = 384 cm^2

What is the main difference between a square and a rhombus?
A.
A rhombus has 4 right angles, and a square does not.
B.
A square must have 4 right angles, but a rhombus may or may not have 4 right angles.
C.
A square has sides that are parallel, but a rhombus does not.
D.
A rhombus is always bigger than a square.
Answer:
B. a square must have 4 right angles, but a rhombus may or not have 4 right angles.
Answer:
B
Step-by-step explanation:
The main difference between a square and a rhombus is a square must have 4 right angles, but a rhombus may or may not have 4 right angles. All the angles of a square have to be 90 degrees. All right angles are 90 degrees. All squares are rhombuses, but not all rhombuses are squares. There are occasions when a rhombus has 4 right angles.
