Answer 1

The value of a is 12

Step-by-step 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 $9.4 \times 10^a$ 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 $9.4 \times 10^a$  we see that value of a = 12 .So , Value of a is 12 in  number of gallons of water in lake mead $9.4 \times 10^a$.
