Step-by-step explanation:
AM switches to PM at 12 PM.
so, we need to calculate the time from 9:23 am to 12 pm, and then from 12 pm to 2:06 pm, and then add both for the overall answer.
the first full hour after 9:23 am is 10 am. from there it is 2 hours to 12 pm.
how many minutes from 23 minutes to 60 (of the next full hour) ? 60 - 23 = 37 minutes.
so, it is 2 hours and 37 minutes until 12 pm.
and from 12 pm to 2:06 pm it is 2 hours and 6 minutes.
the total time is then
2 hours 37 minutes + 2 hours 6 minutes =
= 2 + 2 hours 37 + 6 minutes = 4 hours 43 minutes
FYI
if the sum of the minutes would have been larger than 60 (like e.g. 53 + 12), then we would have had to add another hour as a carry over, and take the remainder of minutes/60 as minutes.
e.g.
2 hours 53 minutes
3 hours 12 minutes
would sum up to
5 hours 65 minutes = 6 hours 5 minutes
Answer:
22.75 minutes or 22 minutes 45 seconds
Step-by-step explanation:
Okay, this is a working together question. Let’s walk through it together!
Firstly, let’s say the total volume of the swimming pool is x sq.meters
Now, the rate of the smaller hose would be x/65 while that of the larger will be x/35
Now, their combined rate would be x/65 + x/35 = 100x/2275
Now, since the volume is x, the time taken is simply, the volume divided by the joint rate. That is mathematically equal to x divided by 100x/2275
x * 2275/100x = 2275/100 = 22.75 minutes or 22 minutes 45 seconds

Answer:
z=4 and z=-1/3 are the zero's
Step-by-step explanation:
To find the zeros of the quadratic function, we need to set it equal to zero.
f(z)=3z^2−11z−4
0 =3z^2−11z−4
Now we need to factor the function
0 = (z - 4) (3 z + 1)
Then using the zero product property set each factor to zero
0 = z-4 0 = 3z+1
Now solve
0+4 = z-4+4 0 -1 = 3z+1-1
4 =z -1 = 3z
-1/3 = 3z/3
-1/3 =z
