<u>Step-by-step explanation:</u>
Here we have , Lake mead contains approximately 28,945,000 acre feet of water and there are about 326,099 gallons in 1 acre foot . We need to find that the approximate number of gallons of water in lake mead is what is the value of a . Let's find out :
We have, 1 acre foot = 326,099 gallons
So , 28,945,000 acre feet = 326,099 gallons ( 28,945,00 )
⇒
⇒
⇒
Therefore , comparing this with
we see that value of a = 12 .So , Value of a is 12 in number of gallons of water in lake mead
