All together there are 48 + 30 books, which comes out to 78 books.  All discount packages contain the same number of books.

Think of the products of integers equal to 48:  3*16, 4*12, 6*8.  Are there more?

Think of the products of integers equal to 30:  3*10, 5*6, 2*15.  Are there more?

Think what these sets of factors have in common:  there could be 8 packages of 6 science books (48 books total); there could be 5 packages of 6 mysteries (30 total).   Doing this, we ensure that every package has the same number of books (6).  We can make (8+5), or 13, packages.

Check:  Does (6 books/package)(13 packages) = 78 books?  YES.

How many times larger is 8*10^6 than 2*10^2
bogdanovich [222]
The first step for solving this question is put both of your given expressions into one and then subtract them. This will look like the following:
8 × 10^{6} - 2 × 10²]
Now to make the calculation easier,, factor the expression.
(8 × 10^{4} - 2) × 10²
Evaluate the power inside the parenthesis.
(8 × 10000 - 2) × 10²
Evaluate the power outside the parenthesis.
(8 × 10000 - 2) × 100
Multiply the numbers inside the parenthesis.
(80000 - 2) × 100
Subtract the numbers in the parenthesis.
79998 × 100
Lastly,, multiply the numbers together to get your final answer.
7999800
This means that 8 × 10^{6} is 7999800 times larger than 2 × 10².
Let me know if you have any further questions.

Which side lengths form a right triangle? <br> (Look in the picture for the answers)
KIM [24]
Pythagoras' Theorem only works with right angle triangles. 

A  makes a right angles triangle because:
   √3² + 4²  = 5

However B doesn't because:
√7² + 8² = 10.631  (which is not 9)

Nor does C because:
√3² + 9² = √90   (which is not √95)

So the answer is A
