So, the smaller the exponent the smaller the number. So one that is -9 is very small.
We first want to compare the numbers through the exponents.
-9 is the lowest exponent, meaning it is the smallest number, so any answer that doesn't start with 7×10^-9 is incorrect
Meaning we can cross out answer choices A and B
-7 is the next to smallest exponent, but Choices C and D both have 4×10^-7 as the second, so we cannot out anymore answers.
After that the final two numbers each have the same exponent, so then we look at the actual numbers.
Which are 1 and 2, they are each risen to the 4th power, meaning they have 4 zero's after the number.
So the two numbers we have are 10000 and 20000
10000 is less than 20000, so that means 1×10^4 comes next in our ordering of least to greatest, leaving 2×10^4 as the greatest
So we order them properly from least to greatest, and our chart is:
7×10^-9 < 4×10^-7 < 1×10^4 < 2×10^4
This is the same as answer choice C, so C is your answer! Hopefully this all makes sense!
Answer:
Note: I'm assuming that he keeps 1/8 of the money spent for himself.
If this is what the question was asking, then the answer would be:
Argyle must sell $4,000 worth of computers.
Step-by-step explanation:
First, we write an equation.
1/8n = $500
Note: n is the variable I'm using to represent the amount of money Argyle must sell to get $500 as commission.
Then, to get the value of n and to get rid of the fraction, we multiply both sides by 8:
1/8n * 8 = $500 * 8
= n = $4000
Therefore, Argyle must sell $4,000 worth of computers to keep 1/8 ($500) as commission.
17x+22 must be equal or less than 80
17x is equal or less than 58.
X is how many shirts he bought
1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121
