Yes
Step-by-step explanation:
An integer, also called a "round number" or “whole number,” is any positive or negative number that does not include decimal parts or fractions. For example, 3, -10, and 1,025 are all integers, but 2.76 (decimal), 1.5 (decimal), and 3 ½ (fraction) are not an integer.
Circumference of the smaller circle, using
, is approximately equal to 18.85 (I used the high floating point precision approximation of pi my calculator has in memory, then rounded to 2 decimal points.)
Using the formula
, which in English says "the smaller circle's circumference is equal to 20% of the larger circle's", we can substitute the known value S:
and solve for L:
.
So the larger circle has a circumference approximately equal to 92.5 units.

Step-by-step explanation:
To create an augmented matrix, we need to transfer the coefficients of each system of equations into its respective place in the matrix. The first row will be the coefficients of the first equation and so on. The number to the right of the equals sign is the last column of the augmented matrix.
Well his salary is $40,000 dollars.
$72,750 - $40,000 = $32,750
This means that 5% of the value of investments he had sold was equal to $32,750.
The stockbroker sold $655,000 worth of investments.
