Answer:
0.4375
Step-by-step explanation:
7/16 is equal to 0.4375
A typical shower drain can remove 480 gallons of water in 3 hours.
For the first-rate;
1,440 gallons in 3 hours
We calculate the unit rate.
By Dividing the total volume by the total time,
1440 / 3 = 480 gallons/ hours
For the second rate:
960 gallons in 120 minutes
Converting minutes to hours:
120 minutes = 2 hours
We calculate the unit rate.
By dividing the total volume by the total time,
960 / 2 = 480 gallons / hour
For the third rate:
720 gallons in 1.5 hours
We calculate the unit rate.
By dividing the total volume by the total time,
720 / 1.5 = 480 gallons / hour
Now,
480 gallons/ hour = 480 / 60 gallons/ minute = 80 gallons per minute

#SPJ9
The <span>height of the tower. is 27 m
Now, we write h/x = tan 45
i.e h/x = 1
i.e h = x ...........................1.
Now, h/(x+20) = tan 30
i.e </span> (x+20)/h = 1/tan 30
or (x+20) = 1.73h
or from equation 1 ,
h+ 20 = 1.73 h
20 = 1.73h - h
h = 20/0.73
or h = 27.39 = 27 m
-9xy squared this is the answer
