Answer:
It take 37.5 hours to fill the tank
Step-by-step explanation:
Given:
Time Taken to fill the tank = 15 hours
Time Taken to empty the tank = 25 hours
To Find:
Time taken to fill the tank when both the inlet and outlet is opened at the same time = ?
Solution:
Let the time to fill the tank be x
In 15 hours the tap fills the tank
Rate at which the tank is filled =
In 25 hours the tap empties the tank
Rate at which the tank is drained =
The net gain per minute on the total filling rate is
=> Rate at which the tank is filled - Rate at which the tank is drained
=>
=>
=>
=> 10x = 375
=>
=>x = 37.5

What you would have to do is distribute your three to each number in the parentheses using multiplication so your answer would be 6y+15
The surface area of the prism will be given by:
SA=(surface area of triangles)+(surface area of rectangles)
surface area of triangles=2(1/2*3*4)=12 sq. units
area rectangles
the length of the hypotenuse will be:
c²=a²+b²
c=√(3²+4²)
c=√25
c=5
area=(3*5)+(4*5)+(5*5)=60
Total area=60+12=72 sq. units
Answer: 72 sq. units
