Answer:
1,000,000,000 identification numbers are possible.
Step-by-step explanation:
We are assigned a 9 digit identification number.
Each digit is a number from 0 to 9. So, each digit has 10 different choices.
Using the Fundamental Counting Principle (is better than the tree diagram) because it's simpler. To illustrate this, we can attempt to draw a tree diagram.
The first column will be the digits 0 to 9.
Then for each of those digits, we need another 0 to 9.
As you can imagine, the amount of numbers grow exponentially, so using the Fundamental Counting Principle is simpler.
And since we have a 9 digit identification number, with each digit having 10 choices, the total number of identification numbers possible are:
So, 1,000,000,000 identification numbers are possible.
120≈100
230≈200
455≈500
175≈200
(100+200+500+200)÷4=250
Hope my answer helped u :)
She drives 35% of the time before lunch.
= 35% of 120 miles.
= 35/100 * 120 . Simply cancel off each zero at the bottom and top.
= 35/10 * 12 = 3.5 * 12 = 42. Using your calculator.
So she drove 42 miles before lunch.
X= total acres on farm
x * 21%= 168
move decimal 2 places to the left to go from percent to decimal form
x * 0.21= 168
divide both sides by 0.21
x= 800 acres
ANSWER: There are a total of 800 acres on the farm
Hope this helps! :)
