What time is 5 3/4 hours after 11:32 pm?<br> Please show work, thank you.
poizon [28]

we have to first convert fraction of hours into minutes

1 hour is equivalent to 60 minutes

then 3/4 hour is - 3/4 of 60

when the of function is used we have to multiply the 2 numbers

then \frac{3}{4} * 60 = \frac{3*60}{4} = \frac{180}{4} = 45

3/4 of an hour is equivalent to 45 minutes

then we have to add 5 hours and 45 minutes to 11.32 pm

add 5.45 to 11.32


11.32

5.45 +

-------

16.77

then its 16 hours and 77 minutes

an hour has only 60 minutes so we subtract 60 minutes from 77 minutes and add that hour to 16 hours

16 hours + 1 = 17 hours 

77 minutes - 60 minutes = 17 minutes

17 hours 17 minutes

time is given in pm therefore its a 12 hour clock

so we have to subtract 12 hours from 17 hours 17 minutes

17.17 hours - 12 hours = 5.17

the new time is 5.17 am of the next day

You’re given two side lengths of 3 centimeters and 5 centimeters. Which measurement can you use for the length of the third side
Kruka [31]

Answer with explanation:

A triangle is valid triangle if sum of length of two sides is greater than the third  side.

Let one side =a = 3 cm

Second side =b = 5 cm

Third Side = c Cm

So, for a valid triangle

1.

a+b > c

3 +5 > c

c < 8 Cm

2.

c+3 > 5

c> 5-3

c>2 Cm

3.

As, 5+c will always be greater than 3.

→→→So, combining 1 and 2 , we get

2 Cm< Third side < 8 Cm, for a valid triangle.
