Answer:
<h2><u><em>
-15</em></u></h2><h2><u><em>
-5</em></u></h2>
Step-by-step explanation:
What is the value of the expression Negative 225 divided b (negative 15)?
What is the value of the expression 30 divided by (negative 6)?
I answer for what I understand
-225 : 15 = - 15
30 : (- 6 ) = -5
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%
