Awater tank is being filled by pumps at a constant rate. the volume of water in the tank v, in gallons, is given by the equation
v(t)=65t+280 where t is the time, in minutes, the pump has been on
at what rate, in gallons per minute, is the water being pumped into the tank

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
