Answer:

Step-by-step explanation:

1/3( x+9/7) + 3^4

Let x = 12/7

1/3( 12/7+9/7) + 3^4

PEMDAS says parentheses first

1/3( 21/7) + 3^4

1/3(3) +3^4

Then exponents

1/3(3)+81

Then multiply

1+81

Sliva [168]

Answer:

$a_1=12$

Step-by-step explanation:

Assuming the geometric series is

$\sum_{n=1}^{\infty} 12*(-\frac{1}{3} )^{n-1}$

then nth term is

$a(n)=12*(-\frac{1}{3} )^{n-1}$ ,

and the first term is found when $n=1$ :

$a_1=12*(-\frac{1}{3} )^{1-1}=12*(-\frac{1}{3} )^0\\\\\boxed{a_1=12}$

Last year at a certain high school, there were 50 boys on the honor roll and 100 girls

Sedbober [7]

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%
