18, I believe 360/20 equals 18.
We can do this problem using two ways....
Let me show you both methods.
<u>Method 1: "Without using logs"</u>
Now, since both sides of the equation have same base and they equal each other, then their exponent must be equal to each other. So, we equal their exponents.
After equaling the exponents, we get,

Now,
<u>Method 2: "Using Logs"</u>
<u>So, either way we get x= 6</u>
If one bag weighs 5 1/4 ibs. Then it is 5 1/4 + (1/2)*(5 1/4) = 63/8 Ib or 7.875 Ib or 7/8
To determine a percentage difference, simply divide the difference of the two numbers by the original. For instance, 82-65.60=16.4 16.4 is 20% of 82, so the discount is 20% (16.4/82)
The product of (3 x 109) and (2 x 109) in scientific notation is 6*10^9
<h3>What is
scientific notation?</h3>
scientific notation can be described as the expression in the form a x 10^b where a is a number or decimal number a is greater than or equal to one.
(3 x 109) * (2 x 109) =6*10^9
Therefore, option D is correct.
