Based on the given above, collection of books of Nathan and Jason can be translated into the following equations:
6J + 1/3N = 134
1/3 J + N = 31; J = Jasons and N=Nathan
Solving two equations with two unknowns simultaneously,
Jason = 21 books and Nathan = 24 books
Answer:
2 packs
Step-by-step explanation:
Since there is 10 packs just divided it by how many notebooks were in the pack.
easy peasy here we go..
so first circumference = 2π R
now it is given that circumference - 30 cm = Diameter;
Diameter = 2πR - 30 = 2 R { diameter = 2 times Radius}
now solving equations:
2πR -2R = 30
πR - R = 15
R ( π - 1 ) = 15
R ( 22/7 - 1) = 15
R ( 15/7 ) = 15
R = 15 x 7 / 15
R = 7 cm

$431.85. I got this by multiplying the amount of weeks in a year (52) by two to get 104. I then multiplied that by 3.5 to get 364. I then added 32.85 and 35 to that to get $431.85
Answer:
The answer is %14.
Step-by-step explanation:
Lets consider that there are 100 people attending to the gym class.
Then we know that 45 person is going to Zumba training.
%5 of people attends all the classes in the gym. Means 5 person attends all the classes. Lets subtract them from 45 person. 45-5=40. We have 40 person left.
%15 of people attends Zumba and yoga, %21 of people attends Zumba and weight lifting. First we need to substract first %5 which attends all classes in the gym from both clusters.
21-5=16 and 15-5-10
We have 10+16=26 person which attends Zumba and one more class. Lets subtract those from Zumba cluster 40-26=14. 14 person is only attending to Zumba classes
