Answer:
The speed of aircraft is 600 mph.
Step-by-step explanation:
Given distance = 120 miles
Time for which jet flew : from 10:20 AM to 10:32 AM
Total duration for which jet flew = 10:32 - 10:20 = 12 minutes
(from 10 hours 32 minutes and 10 hours 20 minutes
10 hours gets cancelled, 32 minutes - 20 minutes is 12 minutes)
here time is in minutes, we have to convert it in hours
we know
60 minutes = 1 hour
1 minutes = 1/60 hour
multiplying LHS and RHS by 12
1*12 minutes = (1/60) *12hour
12 minutes = (1/60) *12hour
12 minutes = 1/5 hours
We know
speed = distance / time
distance = 120 miles
time = 1/5 hours
speed = 120 miles/ (1/5 hours)
speed = 120 * 5 mph = 600 mph
The speed of aircraft is 600 mph.
In order to answer this, you must know how to read or tell time. I'm sure you do. The typical format of time is the 12-hour format. That is 12 hours in the morning and 12 hours in the afternoon. You just simply have to count from 10 in the morning, until you reach 2 in the afternoon. That would be 11, 12, 1 and 2. You passed 4 numbers in the clock. Therefore, her flight took 4 hours.
Answer: (28/37) - (48/37)*i
Step-by-step explanation:
We want to solve the quotient:
To solve it, we need to multiply the whole quotient by the complex conjugate of the denominator.
Remember that for a complex number:
a + b*i
the complex conjugate is:
a - b*i
Then if the denominatoris:
6 + i
the complex conjugate is:
6 - i
Then to solve the quotient we have:
This is equal to:
Then the initial quotient is equal to:
(28/37) - (48/37)*i
D. Corrine is not correct because Hannah also wins if 6 is on the first cube and 1 is on the second, if 5 is on the first cube and 2 is on the second, and if 4 is on the first cube and 3 is on the second.
Step-by-step explanation:
To get a sum of 7 by rolling two cubes, we need to get one of the combinations from the list below:
1 on the first cube, 6 on the second cube
or
6 on the first cube, 1 on the second cube
2 on the first cube, 5 on the second cube
or
5 on the first cube, 2 on the second cube
3 on the first cube, 4 on the second cube
or
4 on the first cube, 3 on the second cube
Therefore, the correct answer option is D. Corrine is not correct because Hannah also wins if 6 is on the first cube and 1 is on the second, if 5 is on the first cube and 2 is on the second, and if 4 is on the first cube and 3 is on the second.
