The value of a is 12
<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 .
Answer:
7
Step-by-step explanation:
The scale factor is how much something is increased by or decreased by.
From the question you can see that the sculpture is 49cm while the model is 7cm length wise
49/7 = 7
When you look at how wide it is it
35/7 = 7
When you look at how tall it is
63/9 = 7
Therefore the scale factor of the model to the sculpture is 7
