It is not recommended that points be marked with X, let's marked with C(6,6)=(Xc,Yc)
The coordinates of the point C(Xc,Yc) which belongs to the line AB and divides line AB in a ratio m : n = 1 : 2 or m/n=1/2 are get it with following formula
Xc=(Xa+(m/n)Xb) / (1+(m/n)) and Yc=(Ya+(m/n)Yb) / (1+(m/n))
We have A(2,2)=(Xa,Ya) and B(14,14)=(Xb,Yb)
When we replace given coordinates we get
Xc=(2+(1/2)*14) / (1+(1/2)) = (2+7) /(3/2) = 9/(3/2) = (9*2)/3 = 3*2 =6 => Xc=6
Yc=(2+(1/2)*14) / (1+(1/2)) = (2+7) / (3/2) = 9/(3/2) = (9*2)/3 = 3*2 =6 => Yc=6
C(Xc,Yc)=(6,6)
Good luck!!!
Answer:
132 square units
Step-by-step explanation:
We are to find the surface area of a square pyramid.
From the diagram above, we are given:
Slant height = 6 units
Base = 8 units
The formula is given as:
= 2bs + b²
= 2 × 8 × 6 + 6²
= 96 + 36
= 132 square units

Answer: 94.8 % (approx)
Step-by-step explanation:
Let the total household in the U.S is x,
⇒ The total household who did not have a telephone in 1960 = 21.5 % of x
= 0.215 x
According to the question,
The total household who do not have a telephone in 1990 = 75.8 % less than the household in 1960 who did not have the cell phone,
= (100-75.8)% of 0.215x
= 24.2 % of 0.215x
= 0.05203x,
⇒ The household in 1990 who had a telephone = x - 0.05203x = 0.94797x
Hence, the percentage of household who has a telephone in 1990
=
=
⇒ Around 94.8% household had telephone in the US in 1990.
