Answer:

Step-by-step explanation:

First consider the unknown original price as 'x'.

Then consider the rate of discount.

To find the sale price, subtract the actual discount from the original amount 'x' and equate this to given sale price.

In the school library, 28% of the books are non-fiction. If there are 1.224 fiction books in
denis-greek [22]

Answer:

1700 books

Step-by-step explanation:

We are given;

  • % of non-fiction books in the library as 28%
  • Number of fiction books in the library as 1,224 books

We are required to determine the total number of books.

First we determine the percentage of non-fiction books

We need to know that;

% of fiction books + % of non-fiction books = 100%

Therefore;

% of non-fiction books = 100 % - 28 %

                                    = 72%

Second we determine the total number of books

We know that;

Total number of books = 100%

But;

72% = 1,224 books

Therefore;

Total number of books = (1,224 × 100%) ÷ 72%

                                      = 1700 books

Hence, the library has a total number of 1700 books

The number is even. It is nit divisible by 3. It is not divisible by 5. It is not greater than 9^2. Is it not less than 8^2. Wha
TEA [102]

Answer:

64, 68, 74, 76

Step-by-step explanation:

Ok so in a confusing way, the last two statements are telling you that the number is greater than 8^2, which is 64, and the number is less that 9^2, which is 81.

The number has to be even, so I will list the even numbers between those two numbers:

64, 66, 68, 70, 72, 74, 76, 78, 80.

It cannot be divisible by 3, which rules out 66, 72, 78

64, 68, 70, 74, 76, 80 remains

It cannot be divisible by 5, which rules out 70 and 80

64, 68, 74, 76  are the possible answers,

*Note: I believe I did this right, but because of the tricky wording of the last two statements, 64 may not be included.
