Answer:
Length of BD = 
+6x - 40
Step-by-step explanation:
In parallelogram ABCD , diagonals AC and BD intersect at E .
In a parallelogram , the two opposite sides are parallel and equal in length.
Also opposite angles of a paralleogram are equal .
Here the length of the parts of a diagonal is given.
BE = 
- 40
DE = 6x
Since the length of whole diagonal is the sum of the lengths of the parts of the diagonal ,
Length of BD = BE + DE
= -40 + 6x
Length of BD = +6x - 40
Answer:
27.
Step-by-step explanation:
x/3 −9=0 Step 1: Simplify both sides of the equation. x/3 −9=0 1/3 x+−9=0 1/3 x−9=0 Step 2: Add 9 to both sides. 1/3 x−9+9=0+9 1/3 x=9 Step 3: Multiply both sides by 3. 3*( 1/3 x)=(3)*(9) x=27
I am not sure but its might be .125
Answer:
The volume of the cone is 3140cm³
Step-by-step explanation:
Volume of come = 1/3 × πr²h
r = diameter/2 = 20/2 = 10cm
h = 30cm
π = 22/7
Volume = 1/3 × 22/7 × 10² × 30
Volume = 1/3 × 22/7 × 100 × 30
Volume = 3142.86cm³
Volume = 3140cm³
