there were 145 boys on the honor role and 60 girls equally given a total number of 205. This year, the number of boys decreased by 20% = 0.2*145=29
145-29=116
116 is this year number of boys on honor role
For girls.
=0.25*60=15
60-15=45
45 is this year number of girls on honor role.
Total number of students on honor role this year is 116+45 =161
Percentage of decrease = 1 -(161/205)*100% =( 1-0.785)*100
= 0.215*100
= 21.5%

Answer:
The length of ST to the nearest tenth of a foot is 5.2 ft
Step-by-step explanation:
Here we have
∡T = 90°
∡R = 64°
RS = 5.8 ft
To answer the question, we have apply sine rule as follows;
Therefore, for triangle RST, we will have;
Therefore;
from which
Therefore, the length of ST to the nearest tenth of a foot = 5.2 ft.
