School A has 216 students and12 classrooms. School B has 104 students
and 4 classrooms.
Part A: What is the ratio of students to
classrooms at School A?
Part B: What is the ratio of students to
classrooms at School B?
Part C: How many students would have
to transfer from School B to School
A for the ratios of students to
classrooms at both schools to be the
same? Explain your reasoning.

Answers

Part A: 216 students/ 12 classrooms= 18 students: 1 classroom.

Part B: 104 students/ 4 classrooms= 26 students: 1 classroom.

The average ratio of students to classrooms in both school is:
[(18 students: 1 classroom)+ (26 students: 1 classroom)] /2= 22 students: 1 classroom.

26 students - 22 students= 4 students.

There are 4 students who would have to transfer from School B to School A for the ratios of students to classrooms at both schools to be the same, which is 22 students: 1 classroom.

If a woman making $25 an hour gets a 10% raise,how much would she now make in an 8 hour work day?

Answers

25*0.1 is 2.5

25+2.5 =27.5

27.5 x 8 = 220

220

The answer is $220

EXPLANATION

To work this out, you would have to firstly add the 10% to $25. To do this you need to find 10% (which is $2.50) and then add it to $25, making the hourly income $27.50

We would then times this by 8 to get the final answer of $220.

What is the answer to x - 9x ?

Answers

On solving the equation we get '- 8x'.

We have x - 9x.

We have to solve it.

What do you mean by solution of a function f(x) ?

The solution of a function f(x) is the value of x for which f(x) = 0.

According to the question -

f(x) = x - 9x

Now -

x - 9x = - 8x

Hence, on solving the equation we get '- 8x'.
