Answer:
6.5 x 10^6 To answer this question, you need to divide the mass of the sun by the mass of mercury. So 2.13525 x 10^30 / 3.285 x 10^23 = ? To do the division, divide the mantissas in the normal fashion 2.13525 / 3.285 = 0.65 And subtract the exponents. 30 - 23 = 7 So you get 0.65 x 10^7 Unless the mantissa is zero, the mantissa must be greater than or equal to 0 and less than 10. So multiply the mantissa by 10 and then subtract 1 from the exponent, giving 6.5 x 10^6 So the sun is 6.5 x 10^6 times as massive as mercury.

Answer:
Its the first choice.
Step-by-step explanation:
x^2+4x-4 = 8
x^2 + 4x - 4 - 8 = 0
x^2 + 4x - 12 = 0
(x + 6)(x - 2) = 0
x = -6, 2.
Answer:
Step-by-step explanation:
Number of persons said it is legal to text while driving = 8
Number of persons said it is illegal to text while driving = 804
Total persons sampled = 804+8 = 812
Since probability =
The probability of randomly selecting someone who believes it should be legal to text while driving =
Required probability =
It is rational because it is a terminating decimal. It can be represented as a ratio of two integers (121/10)
