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.
20! / 16! =
20*19*18*17*16*15*14*13*12*11*10*9*8*7*6*5*4*3*2*1
divided by
16*15*14*13*12*11*10*9*8*7*6*5*4*3*2*1
equals C. 116,280
Answer:
D
Step-by-step explanation:
The pentagon has 5 interior angles that add up to 360. To find the angle of rotational symmetry, divide 360 by 5 (you get 72). So if you rotated the shape 72 degrees, it will map onto itself. 72 times 2 is 144, and that's rotating the shape 72 degrees twice, so it will stay the same.
2x-7 * x
----------- =. 100^2= 10000
2
2x^2-7/2= x^2-7/2
x^2-7/2=10000
x^2 = 20007/7
