Answer:

There are total 30 books in the 5 feet high stack of books.

Step-by-step explanation:

The complete question is

Given, Each note book is 2 inches thick, How many notebooks do you think it would take to make a stack that is 5 feet high

Solution

Thickness of each book = \frac{2}{12}  = \frac{1}{6}

The total height of the book stack is 5 feet.

The number of books in the stack is equal to total height of the stack divided by the thickness of one book

Number of books in five feet high stack is

\frac{5}{\frac{1}{6} } \\5 * \frac{6}{1} \\30

Hence, there are total 30 books in the 5 feet high stack of books.

Sanjay and Felipe are putting together a 500-piece puzzle. Sanjay could do the entire puzzle by himself in 6 hours, while it wou
Nata [24]

What is the time it takes Sanjay to complete the puzzle? 6 hours

What is the time it takes Felipe to complete the puzzle? 8 hours


We can use the general formula of rate and time to solve this problem. Generally we have,

<em><u>Rate * Time = Work/Job</u></em>

<em>** where Work/Job for this problem is 1 since they are doing 1 work, which is solving a puzzle</em>


  • <u>Finding rate of Sanjay:</u>

R(6)=1\\R=\frac{1}{6}

  • <u>Finding rate of Felipe:</u>

R(8)=1\\R=\frac{1}{8}


Working together, their rate is the sum,

Total Rate = \frac{1}{6} + \frac{1}{8} = \frac{7}{24}.


Using the general formula again, we can find the time it will take to solve the puzzle when both works together.

(\frac{7}{24})T=1\\ T=\frac{1}{\frac{7}{24}}= \frac{24}{7} = 3.43 hours

Rounding the answer, we have 3.4 hours.


ANSWER: 3.4 hours

Lisa ran around a rectangular field 150 m long and 50 m wide at an average speed of 100 m/min. How long did she take to complete
Anarel [89]

Answer:

20 minutes

Step-by-step explanation:

To make one round of the field, Lisa will have to cover the entire perimeter of the field.

The perimeter of a rectangle = 2(l+w) Where L = length and W = width.

The multiplication of 2 means two lengths and widths that each rectangle has. The perimeter of the field = 2(150 +50) = 400m

Lisa's average running speed = 100m/min

The time taken to cover one round of the field or one perimeter of the field = 400/100 = 4 minutes.

To cover 5 rounds or 5 perimeters Lisa will take 5x4 minutes = 20 minutes.

Dina has a mass of 50 kilograms and is waiting at the top of a ski slope that’s 5.0 meters high. What is her potential energy
Bess [88]

Answer:

C

Step-by-step explanation:

Formula for potential energy is PE = m*g*h

where

m is the mass, in kg

g is the acceleration due to gravity, in meters per second squared, and

h is the height, in meters

The problem gives m = 50, g = 9.8, and h = 5. We plug that into the formula and get out answer. So:

PE=mgh\\PE=(50)(9.8)(5)\\PE=2450

Correct answer is C.
