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 
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
Answer:
Step-by-step explanation:
area of a square = S x S
side = ⱱarea
side = ⱱ100
side = 10cm
perimeter = 4s
= 4 x 10
=40cm
Answer: 19 cupcakes and 37 cookies were sold.
Step-by-step explanation:
Let x represent the number of cupcakes that Jesse sold yesterday.
Let y represent the number of cookies that Jesse sold yesterday.
If he sold 56 cupcakes and cookies combined, it means that
x + y = 56
Each cupcake sold for $1.50 and each cookie sold for $0.25. At the end of the day, Jesse had sold $37.75 worth of cookies and cupcakes. This means that
1.5x + 0.25y = 37.75 - - - - - - - - - - -1
Substituting x = 56 - y into equation 1, it becomes
1.5(56 - y) + 0.25y = 37.75
84 - 1.5y + 0.25y = 37.75
- 1.5y + 0.25y = 37.75 - 84
- 1.25y = - 46.25
y = - 46.25/ - 1.25
y = 37
x = 56 - y = 56 - 37
x = 19
Calculate the volume, that is easy:
<span>4 x 5 x 2.5 = 50m3 </span>
<span>now, as you did not provided if you use nitrogen in </span>
<span>ntp (normal temperature and pressure - 20c, 1atm) weight is 1.165kg/m3 </span>
<span>or: </span>
<span>stp (standard temperature and pressure - 0c, 1atm) weight is 1.2506 </span>
<span>these are in case of pure nitrogen, as in presented case nitrogen is only 79% we need to change weights to represent that: </span>
<span>ntp - 1.165kg/m3 / 100% x 79% = 0.92035kg/m3 </span>
<span>stp - 1.2506kg/m3 / 100% x 79% = 0.987974kg/m3 </span>
<span>therefore in case of: </span>
<span>ntp, total weight of n2 will be 50m3 x 0.92035kg/m3 = 46.0175kg </span>
<span>stp, total weight of n2 will be 50m3 x 0.987974kg/m3 = 49.3987kg</span>
