(b) Write down a possible number of students in the class

Answers

Answer 1

Step-by-step explanation:

A: adding together 2 and 3 a bunch of times (2+3+2+3+2+3 etc) does not equal 28.

A possible answer could be 27 students.

Answer 2

The requried,
(a) Ben is wrong because the number of students is incorrect,
(b) The required possible number would be either 25 or 30.

What is the Ratio?

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

here,
As mentioned in the question, the ratio of boys to girls in a class is 2:3

Ben says there are 28 students in the class.


So total of the ratio = 2 + 3 = 5
Now calculate number of boys = 2 / 5 [28] = 7.2 [this is not possible]
So the total number of students must be that number which is divisible by 5 and nearby 28, so the number would be 25 or 30.

Thus, the requried,
(a) Ben is wrong because the number of students is incorrect,
(b) The required possible number would be either 25 or 30.

C. F(x) is a very large positive number
D. F(x) is a negative number with a small absolute value

Answers

Answer:

B. F(x) is a negative number with a large absolute value.

Step-by-step explanation:

The Y and X axes in this case are asymptotes, it means that the function will never touch them. When x is negative and is so small, the function tends to negative infinity, because the function try to cut it but it will never happen.

On the morning of the sale, the store donated 50 pairs of shoes to a homeless shelter. Then they sold 64% of their remaining inventory during the sale. If the store had 288 pairs after the donation and the sale, how many pairs of shoes did they have at the start? how many shoes did they have at the start?

Answers

Answer:

850.

Step-by-step explanation:

Let the number at the start be x shoes. Then:

x - 50 - 0.64(x - 50) = 288

x - 0.64x - 50 + 32 = 288

0.36x = 288 + 50 - 32

0.36x = 306

x = 306/0.36 =  850.

Answer:

850 is the answer to the question
