Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The height of the 10 stacks of books is 22cm.
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that the front and back covers of a textbook are each 0.3 cm thick. Also, there are 200 sheets of paper between the cover and the thickness of each sheet is 200 sheets. Therefore, the thickness of the book is,
The thickness of a single book
= (Number of covers × Thickness of cover) + (Number of sheets × Thickness of sheets)
= (2 × 0.3cm) + (200 × 0.008cm)
= 2.2 cm
Now, the thickness of 10 books will be,
The thickness of 10 books = 10 × the Thickness of a single book
= 10 × 2.2 cm
= 22 cm
Hence, the height of the 10 stacks of books is 22cm.

Answer:
22 cm
Step-by-step explanation:
Start off by multiplying the number of pages by the thickness.
200*0.008=1.6
Add the thickness of the front and back cover.
1.6+0.6=2.2
Multiply by 10.
2.2*10=22 cm

Answer:
x > -5
Step-by-step explanation:
Answer:
Step-by-step explanation:
2(x-3)-5x<9 expand left side
2x-6-5x<9. group like terms on left side
-3x-6<9. add 6 to each side
-3x<15. divide each side by -3 (reverse sign because of division by a negative)
x>-5
1 - 4i
-3
5
1 + 4i
Answer:
The answer would be 5!
Step-by-step explanation:
You start with 1+2i and the conjugate of this would be 1-2i!
After that, in order to find the product, you multiply (1+2i)(1-2i)
You can use distribution or you can use the formula (a+b)(a-b)=a^2-b^2
Either way the answer will be 1-4i^2
i^2=-1 so you replace the i^2 in our equation with negative 1 and solve to get 5!
