Hi abmusical2021,

he is always changing his question, 

my answer is correct just like your a. .

Straight

1.4 miles / 2.8 minutes = 0.5 mile/minute

Hi Guest this is very messy but this is 9x9x4x8x9. 9x9x9 is 729, so this is 729x4x8. 4x8 is 32, so this is 729x32, which is 23328.

hello

Hello Guest (?),

what does this mean?

You should also remember to only ask questions that make sense or make others puzzle.

It is taken seriously.

Thank you.

Edit: 9 multiply by 9 is 81. (9 * 9 = 81)

Helli abmusical2021,

i accept your apology, at least you apologised, the others would probably keep writing or unfortunately insulting.

Thank you.

ok sorry

Hello abmusical2021,

you don't have to answer again a question that has already been answered, only if you got another answer out of it - not in this case .

That answer would be better if it has a calculation step - like in this case \(\rightarrow\) Someone has answered a question with (!) calculation step and you just write it down. It looks like you stole it from that person with (!) the calculation path. Also, it's not called disliking directly if you know you made a mistake, they would apologise there, and you are also aware of what you are disliking, even though you know it's only true.

Hello straight i wasnt stealing i did the problem i just didnt show step

this is 1 mile in 2 minutes, so 0.5 mile 1 minute

Hello abmusical2021,

Stop stealing the solutions from the other questions that have already been answered!

And that doesn't mean that you have to disliked everything if you made the mistake and you are aware that it is not allowed.

Please stop it.

In ms E's park 1/3 of the total birds were grey in color while the rest were either black or white. The white birds were twice as many as the black birds. After Ms E bought another 8 white birds and 8 black birds. The ratio of the number of white birds to the number of grey birds became 3:2. How many black birds did Ms E have in the end?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

All birds => x

Grey => x/3  or  3x/9

Black => 2x/9

White => 4x/9

Ratio      W : G = 4 : 3     (Before 8 white birds were added)

New ratio =>         (4x/9 + 8) / (3x/9) = 3 / 2        x = 144

Black birds =>     2x/9 + 8 = 40

There are some caps in a shop. 2/9 of the caps are red, 1/3 of the caps are yellow and the rest are blue. There are 436 more blue caps than red caps. How many caps are there in the shop?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

All caps => x

Red caps => 2x/9

Yellow caps => x/3  or   3x/9

Blue caps =>  x - 5x/9 = 4x/9

Caps in the shop =>   2x/9 = 4x/9 - 436    x = 1962

Hello abmusical2021,

stop it, that's not cool...

Hello Guest,

almost right, but there are 36 positive integers, less than 1000 and not equal to or larger.

Anyway, everyone makes mistakes ...

Hello Guest,

Evaluate the infinite geometric series: 1 + 2/7 + 4/49 + 8/343 + ...

\({\color{red}Solution:}\)

\(1 + \frac{2}{7} + \frac {4}{49} + \frac {8}{343} + \mbox { } ...\)

\( \mathcal{ \mbox {Like Guest said it right } } \mbox { } (^2/_7)^0 + (^2/_7)^1 + (^2/_7)^2 + (^2/_7)^3 + \mbox { } ...\)

Use the double summation sign \(\sum\) .

\(\displaystyle\sum_{n=1}^{\infty} \Bigl( \frac {7}{2} \Bigr)^{1 - n} = \frac {7}{5} = 1.4 \) .
