Answer:

In order, your numbers are

22, 45, 75, 89, 89, 95, 100

The median is the number that is in the middle numbers of all your numbers. The median is 89, since it is in the very middle.

The mean is all your numbers added together and then divided by how ever many numbers you have. 22 + 45 + 75 + 89 + 89 + 95 + 100 = 515. Since you have 7 numbers, you would divide 515 by 7, which equals 73.5. The mean is 73.5.

The mode is the number that has the most numbers(not sure how to word it) Since 89 has two of the numbers, and no other numbers have duplicates, your mode is 89.

This is the formula for the volume of a right square pyramid, where a is the side length of the base and h is the height: . Whic

Lesechka [4]

Answer:

C. h=3V/a^2 is the correct answer

Step-by-step explanation:

Given:

V=1/3a^2h

It can be rewritten as

V=1/3 *( a^2) * h

Divide both sides by (1/3)*h

V / (1/3*h) = (1/3)* (a^2) * h / (1/3)*h

V÷1/3*h = a^2

V÷3/1*h=a^2

3V/h=a^2

Multiply both sides by h

3V/h*h=h*a^2

3V=h*a^2

h=3V/a^2

C. h=3V/a^2 is the correct answer

3. JK Rowling and R.L. Stine are both reading the Hunger Games. J.K. reads 35

Crank

Answer:

Part A:

For J.K. Rowling: 17.5pages/hour

For R.L. Stine: 15pages/hour

Part B:

J.K. Rowling will finish the book first.

Step-by-step explanation:

Part A:

The rate of change in this case represents how much changes a variable in a specific period of time. The variable is the amount of pages.

You have to calculate the amount of pages that J.K. Rowling and R.L. Stine read in one hour.

For J.K. Rowling, 35 pages every 2 hours can be written as:

If you divide 35/2 you can obtain the amount of pages in one hour:

17.5pages/hour (17.5 pages per hour)

For R.L. Stine, 45 pages every 3 hours can be written as:

If you divide 45/3 you can obtain the amount of pages in one hour:

15pages/hour (15 pages per hour)

Part B:

In order to calculate who will finish the hunger games first, you have to calculate the amount of time needed to finish the book.

For J.K. Rowling:

You have to multiply 355 pages by (because in one hour she reads 17.5 pages) to obtain the amount of hours

For R.L. Stine:

You have to multiply 355 pages by (because in one hour he reads 15 pages) to obtain the amount of hours

So, J.K. Rowling will finish the book first because she needs less time than R.L. Stine.

Which is equivalent to (3/125)*?

Musya8 [376]

$\huge\text{Hey there!}$

$\huge\textbf{Question reads:}$

$\large\textbf{Which is equivalent to }\rm{\bf \dfrac{3}{125}}\large\textbf{ ?}$

$\huge\textbf{Solving for your fraction:}$

$\mathbf{\dfrac{3}{125}}$

$\mathbf{= \dfrac{3\times2}{125\times2}}$

$\mathbf{\approx \dfrac{3 + 3}{125 + 12{5}}}$

$\mathbf{= \dfrac{6}{250}}$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{\frak{\dfrac{6}{250}}}\huge\checkmark$

$\large\text{By the way, they are a lot more fractions that are equivalent to}\\\large\text{the given equation (}\rm{\dfrac{3}{125}}\large\text{) but we only labeled one that is the very}\\\large\text{first fraction that is equal to it. }$
