Answer 1

The value of a is 12

Explanation:

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
`9.4 * 10^a` 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 )

⇒
`326,099 (28,945,000 )`

⇒
`9.4389356e+12`

⇒
`9.4(10^(12))`

Therefore , comparing this
`9.4(10^(12))` with
`9.4 * 10^a` we see that value of a = 12 .So , Value of a is 12 in number of gallons of water in lake mead
`9.4 * 10^a`.
