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:
c=26
Step-by-step explanation:
So you would use the formula a^2+b^2=c^2
10^2+24^2=c^2
100+576=c^2
C^2=676
c=26
Answer: (x-3)(2x+1)(8)
Step-by-step explanation: First factor out the 8 to get (8)(2x^2-5x-3). So now we have what number multiply out to -6 (ab) and add up to -5. -2 and -3 work out so we manipulate the equation like (8)(2x²-2x-3x-3). Factor out 2x in the first term and -3 in the second and keep going.
Answer:
