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.

Step-by-step explanation:
Answer:
(3,-7)
Step-by-step explanation:
Midpoint Formula
(3,-9) = ((3+x)/2 , (-11+x)/2)
Solve for x coordinate
Solve for y coordinate
Therefore point s is (3, -7)

Answer:
x = 33
Step-by-step explanation:
Sum of the interior angles of a 5-sided polygon = 540°
Therefore all the interior angles of the given polygon would all be equal to 540°.
Thus:
(4x - 25)° + (3x + 25)° + (2x - 3)° + (4x)° + (3x + 15)° = 540°
Solve for x
4x - 25 + 3x + 25 + 2x - 3 + 4x + 3x + 15 = 540
Combine like terms
4x + 3x + 2x + 4x + 3x - 25 + 25 - 3 + 15 = 540
16x + 12 = 540
16x = 540 - 12
16x = 528
Divide both sides by 16
x = 33
