Aplane ride lasted 6.4 hours. how many seconds did the plane ride last? if necessary round your answer to the nearest tenth of a second

23,040 seconds.

Step-by-step explanation:

We have been given that a plane ride lasts 6.4 hours. We are asked to find the number of seconds, the plane ride lasted.

We know that 1 minute equals 60 seconds.

1 hour = 60 minutes = 60*60 (3600) seconds.

To find the number of seconds the plane ride lasted, we will multiply 6.4 by 3600.

Therefore, the plane ride lasted for 23,040 seconds.

23, 040 seconds

Step-by-step explanation:

Given: A plane ride lasted  =6.4 hours.

We know that 1 hour = 60 minutes

And 1 minute = 60 seconds

Therefore, the number of seconds in one hour=

Now, the number of seconds the plane last is given by ;-

Hence, the plane ride lasted 23,040 seconds.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
