Step-by-step explanation:
r u serious?
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%
Part 1: Create a scenario for an arithmetic sequence. For example,
Jasmine practices the piano for ten minutes on Monday. Every day she adds her
practice time by five minutes. If she continues this pattern, in the 7th day she will practice for 10 + 5 + 5 + 5 + 5 + 5 + 5 = 10 + 6(5) = 10 + (7 - 1)(5) = 20 + 30 = 40 minutes.
Hence the function for the 7th term in the sequence is a + (7 - 1)d = a + 6d where a is the number of minutes Jasmine practiced the piano on Monday and d is the additional number of minutes added by Jasmine to his practice time evey day.
