Pose a question for which a two-way table is appropriate. Be creative here!
arlik [135]
Define an issue that is important to you (politics, medicine, social media, education, etc.), and think about some things you might want to know about this issue. Briefly explain your issue and what you hope to learn or understand. Pose a question for which a two-way table is appropriate. Be creative here! Collect data from at least 20 people (or other sources). Display your data in a two-way frequency table like the one shown below. Your table can have more rows or columns if you need them. I am not quite sure of what the question is supposed to be.

What is the volume of a sphere with a radius of 12 units?

\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

\sf{Formula \ for \ Volume \ of \ a \ sphere \ : \bigstar\boxed{\bold{V=\displaystyle\frac{4}{3} \pi r^3}}

Where

\tt{V=Volume}\\\tt{\pi =pi}\\\tt{r=radius}

Provided Information:-

\tt{r=12\:units}

Plug in:-

\bold{V=\displaystyle\frac{4}{3} \pi (12)^3}

\bold{V=\displaystyle\frac{4}{3} \pi (1,728)}

On further simplification,

\dashrightarrow\boxed{\boxed{\underline{\bold{V=2304\pi\:m^3}}}}\dashleftarrow

<h3>Good luck.</h3>

If a conveyor belt moves about 450 ft in 3/8 h, what is the unit rate?
soldier1979 [14.2K]
450 / (3/8) = x / 1....450 ft to 3/8 hr = x ft to 1 hr
cross multiply because this is a proportion
(3/8)(x) = (450)(1)
3/8x = 450
x = 450 * 8/3
x = 3600/3 reduces to 1200

so the conveyor belt moves at the unit rate of 1200 ft per hr

Help with math problem. ​
xxTIMURxx [149]

Answer:


Number of logs:


1. 48


2. 14


3. 90


4. 48


5. 100


Total: 300


Step-by-step explanation:


Just multiply the height with the number of trees then divide by 6. This is in theory if the length of all the trees were conjoined, as there would most likely just be less, then 300. This is because the remainder would be that of the multiplied trees height instead of getting the remainder of wood from each tree. So in case you want to try doing that option, simply divide the height first in feet by 8, then multiply that by the number of trees to give you an accurate answer of logs.

Answer:

C (2,3)

Step-by-step explanation:

All you have to do is substitute in the x and y values.

x=2 y=3

3=2+1 So that is correct.

Then -1/2 times 2+4=3! This is correct.

So the answer is C. Hope this helps, have a good day. c;

If you have a calculator use that and you should get the same answer.
