Question 1 what is −12÷2/3
question 2 what is -8/3÷7/12
question 3 divide.8.64÷(−0.27)
question 4 starting at sea level, a submarine descended at a constant rate to a depth of −3/4 mile relative to sea level in 5 minutes. what was the submarine's depth relative to sea level after the first minute?
enter your answer in a fraction in simplest form.
question 5 one cold night the temperature was 0 degrees at 8 p. m. the temperature dropped at a constant rate from 8 p. m. to midnight. at midnight the temperature was −16.8 degrees.
what was the temperature at 9 p. m.?

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

answer: -0.5 would be the most likley outcome

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
