Answer:
The population of California is about 5 times the population of south Dakota
Step-by-step explanation:
Let
x ------> the population of California
y -----> the population of south Dakota
we have
x=4,000,000 people
y=800,000 people
Divide the population of California by the population of south Dakota, to find out how many times the population of South Dakota is the population of California
so
x/y
substitute
4,000,000/800,000=5
therefore
The population of California is about 5 times the population of south Dakota

Answer:
3 * 10 ^-2
Step-by-step explanation:
When we divide numbers in scientific notation first divide the number portion
2.7 /9 =.3
Then divide the exponents
10 ^5 / 10 ^6 = 10 ^ (5-6) = 10 ^ -1
.3 * 10 ^-1
We cannot leave the .3 since the first number has to be between 1 and less then 10
Move the decimal 1 place to the right which means subtract 1 from the exponent
3 * 10 ^-2
19.2 is the answer because if you move the decimal over until its a whole then just divide
