It’s going to be 1/6 because if you roll the dice twice and it has 6 sides it’s 1/6
Answer:
The answer is given below
Step-by-step explanation:
The question is not complete. The correct question is:
A square based pyramid have a height of 30 cm and base of 10 cm. The The square based pyramid is cut horizontally at a height of 15cm to leave this frustum.
Answer:
The frustum would have a base of 10 cm and height of 15 cm. The lower base has a length of 10 cm. to calculate the upper base, we use the formula:
Substituting:
The volume of the frustum is given by the formula:
Where h is the height of the frustum = 15 cm, A1 is the area of the lower base = 10 * 10 = 100 cm², A1 is the area of the upper base = 5 * 5 = 25 cm²
Substituting gives:
9514 1404 393
Answer:
27 cm³
Step-by-step explanation:
The surface area of a cube is ...
SA = 6s²
Then the edge length is ...
54 cm² = 6s² . . . . . please note that cm³ is not the appropriate unit for area
9 cm² = s² . . . . . .divide by 6
3 cm = s . . . . . . . take the square root
The volume of a cube is ...
V = s³
V = (3 cm)³ = 27 cm³
The volume of the cube is 27 cm³.
Multiply both sides by 2 so u get:
-4x+y=36
y=36+4x
y=0
0=36+4x
-9=x
-9 is your x-intercept
Answer:
<u><em>ΔEAB ≅ΔFCD</em></u>
Step-by-step explanation:
As ABCD is a parallelogram opposite sides are equal s AE ≅CF ,also AB≅ DC . Both E and F bisect the opposite lines in equal halves.
The parallelogram has a property that its opposite angles are equal . Therefore ∠c≅∠a, ∠d≅∠b
Using the SAA≅SAA postulate we conclude that ΔEAB ≅ΔFCD
