Answer:
The expression that fits the description is ;
(8a + b)/4
Step-by-step explanation:
Here, we want to find the expression that fits the given description;
We are told that the expression is a sum of two terms
The first term is 2 * a = 2a
The second term is the quotient ( result of division) of b and 4 = b/4
So the term we are looking for is;
2a + b/4 = (8a + b)/4
Answer:
Ten and a Half milkshakes can be prepared from the available amount of ice cream.
Step-by-step explanation:
The total vanilla ice cream = 7/8 gallons
Ice cream used for 1 milkshake = 1/12 gallon
Now, total number of milkshakes possible = 
= 
Hence ten and a half milkshakes can be prepared from the available amount of ice cream.
Answer: Eleventh Grade
Step-by-step
The ratio of tenth graders to the school's total population is 86:255 = 33.7%.
The ratio of eleventh graders to the school's total population is 18:51 = 35.3%.
Since the probability of a student being in either tenth, eleventh, or twelfth grade = 1 = 100% (that is, certainty), then the probability of a randomly drawn student being in twelfth grade is (100-33.7-35.3)% = 31.0%.
When randomly choosing one student from the whole school, it is most likely (35.3%) that the student is in the eleventh grade.
Assume N students
Student 1 can get (n-1) papers
Student 2 can get (n-1) papers
Student 3 can get (n-1) papers
etc
Student N can get (n-1) papers
So for N students you can have N(n-1)
