Solve the inequality 2x - 5 <= -x + 12 - 3x + 19 

Hello Guest!

\(2x - 5 <= -x + 12 - 3x + 19 \\ 6x\leq 36\\ x\leq 6 \)

\(\color {blue}x\in\mathbb R\ |\ \)\(\color{blue}-\infty < x \le 6\)

AB = 8.

900  -  180  -  112  +  22 ==630

sorry about the latex, the url is not working

sry

the website url wasn't working, so i just pasted in LATEX, my bad

Let \(r\) and \(h\) be the radius and height of the smaller cone, respectively. 

The volume of the new shape is \(\pi r^2 h \over 3\), and the volume of the old shape is \(\pi (2r)^2 2h \over 3\).

The answer is the volume of the new shape over the volume of the old shape. 

Can you take it from here?

PR  =sqrt (3^2 + 4^2)  =  sqrt (25)  = 5

PQ =  sqrt (3^2 + 5^2)  =  sqrt (34)

OR =  sqrt (4^2 + 5^2) = sqrt (41)

Semiperimeter   =  (5 + sqrt (34) + sqrt (41) )  / 2

[ PQR ]  =  sqrt  ( S ( S - 5) ( S - sqrt 34 ) ( S -sqrt 41 ) )   =   sqrt (769) /  2 

Can't read!!!

I already answered a similar problem for you here: https://web2.0calc.com/questions/pls-help_7181

17/100=0.17

Which is very close to 1/6, which is approximately 0.16

1  5  9   .....   197

3  7 11  .....   199

There will be   5 houses with one  digit  =  $5

There will be 45 houses with  two  digits =  45 (2) =  $90

There will be  50 houses with three  digits  = 50 (3)  = $150

He earns      5 + 90  + 150  =  $ 245
