This is because astronauts can't sprinkle salt and pepper on their food in space. The salt and pepper would simply float away. There is a danger they could clog air vents, contaminate equipment or get stuck in an astronaut's eyes, mouth or nose. Astronauts eat three meals a day: breakfast, lunch and dinner.
Step-by-step explanation:

So sqrt(40) lies between 6 and 7.
Factoring the top and bottom of the fraction we get
(x + 4)(x - 3
---------------
(x + 4) (x - 4)
Answer:
2 1/2
Step-by-step explanation:
Turn both fractions into improper fractions, multiply the whole number by the denominator and add the numerator.
4 3/4
4 * 4 + 3 = 19
19/4
2 1/4
2 * 4 + 1 = 9
9/4
Now since she drank 2 1/4 gallons of juice, subtract 9/4 from 19/4.
19/4 - 9/4 = 10/4
Now turn back into a mixed fraction, do this by putting 4 into ten twice and taking the remainder and putting it as numerator:
4 * 2 = 8
10 - 8 = 2
2 1/2
