Answer:
959.42 x 10³
Step-by-step explanation:
9.62 x 10⁵ - 2.58 x 10³
= 962 x 10³ - 2.58 x 10³
= 959.42 x 10³
Really none of the above.
A principal square root of a real number is a positive real number (or a positive real number times i, if you're up to complex numbers, but let's assume not.) It's not necessarily a positive integer, √2 being the obvious example.
Is √2 a positive fraction? We can write it as √2 / 1 so I suppose it is. It's certainly not a rational number. Even if we grant irrationals as fractions surely √0=0 isn't a positive fraction. So "always" isn't correct.
I'd go with none of the above, but if I had to choose I'd choose D.
Answer:
If you wan to go on the two rides with the shortest wait times (Dr. Zoom & Dueling Dragons), it should take 15 1/6 minutes.
Step-by-step explanation:
9 1/3 --> 9 2/6
9 2/6+5 5/6=15 1/6
First divide by 4 to get x^2=9. Then take the square root of both sides. x=3 and x = -3.
