The front and back covers of a textbook are each 0.3 cm thick. Between the covers are 200 sheets of paper, each 0.008 cm thick. How high is a stack of 10 books

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.

What is multiplication?

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

1.   C = ⁵/₉F - 32
9C = 9(⁵/₉F - 32)
  9C = 9(⁵/₉F) - 9(32)
  9C = 5F - 288
- 5F - 5F
  9C - 5F = -288
- 9C   - 9C
-5F = -9C - 288
-5 -5
F = 1⁴/₅C + 57.6

2. $H = w + (50)/(m^(2))$
   $m^(2)(H) = m^(2)((50)/(m^(2)))$
   $Hm^(2) = 50$
   $(Hm^(2))/(H) = (50)/(H)$
   $m^(2) = (50)/(H)$
   $\sqrt{m^(2)} = \sqrt{(50)/(H)}$
   $m = (√(50))/(√(H))$
   $m = (5√(2))/(√(H))$
   $m = (5√(2))/(√(H)) * (√(H))/(√(H))$
   $m = (5√(2H))/(H)$

3. A = 5 + 4√x
- 5 - 5
  A - 5 = 4√x
  (A - 5)² = (4√x)²
  A² - 10A + 25 = 16x
16 16
¹/₆A² - ⁵/₈A + 1⁹/₁₆ = x

4. $A = (b + c)/(b)$
   $Ab = b((b + c)/(b))$
   $Ab = b + c$
   $Ab - b = c$
   $b(A) - b(1) = c$
   $b(A - 1) = c$
   $(b(A - 1))/(A - 1) = (c)/(A - 1)$
   $b = (c)/(A - 1)$

HELP i dont know how to do this

Answers

Answer

Step-by-step explanation:

First, lets go through B-D and explain why they are correct.

B= f represents the number of flash drives. This means that the coefficient, 10, would be the cost per flash drive.

C= n represents the number of cases of paper. it says so in the question, so that one is a bit easier.

D= f represents the amount of packages of hanging folders. If the coefficient for B is the cost, then that would be the same case for D. Therefore it is correct because the coefficient is 13.

A would be incorrect because the coefficient represents the amount that one item costs. P is the packs of pencils, meaning that it would be $7 per pack of pencils.

Hope this helps!

You are at a stall at a fair where you have to throw a ball at a target. There are two versions of the game. In the firstversion, you are given three attempts, and you estimate that your probability of success on any given throw is 0.1.In the second version, you are given five attempts, but the target is smaller, and you estimate that your probability ofsuccess on any given throw is 0.05. The prizes for the two versions of the game are the same, and you are willing toassume that the outcomes of your throws are independent. Which version of the game should you choose? (Hint: Inthe first version of the game, the probability that you do not get the prize is the probability that you fail on all threeattempts.)
