The annual salary of Mrs. Fredrick is $ 39397.2
<u>Solution:</u>
Given, Mrs. Frederick is paid semimonthly.
Her semi-monthly salary is $1.641.55.
Now, let us find her monthly salary first.
<em>monthly salary = 2 x semi – monthly salary </em>
So, monthly salary = 2 x 1,641.55 = $ 3283.1
Since there 12 months in a year, we obtain the annual salary as follows:
Now, the<em> annual salary = 12 x monthly salary </em>
Annual salary = 12 x 3283.1 = $ 39397.2
Hence, the annual salary of Mrs. Fredrick is $ 39397.2
If 55% of the student body are boys, then 45% are girls.
35% of boys are on the honor roll, so 35% of 55% are on the honor roll.
40% of girls are on the honor roll, so 40% of 45% are on the honor roll.
So now we need to find each of those numbers...
35% of 55% =
.35 * .55 = .1925 multiply by 100 to convert to percent
19.25% of boys (in the student body) are on honor roll
40% of 45% =
.40 * .45 = .18 multiply by 100 to convert to percentage
18% of girls (in the student body) are on honor roll
Add the two together to get the total percentage of student body that is on the honor roll...
19.25% + 18% = 37.25%
Round to the nearest percent
37%

The operation between a rational and a irrational number that results in a rational number is a multiplication, hence the expression ab could represent a rational number.
<h3>What are rational and irrational numbers?</h3>
If a number can be represented by a fraction, it is rational, otherwise, it is irrational.
The addition/subtraction of a rational and an irrational numbers is irrational, while the multiplication is rational, hence the expression ab could represent a rational number.
