Answer:

All of area is πr²

Step-by-step explanation:

and we should write the area kind of radian. So if all area is π*(12)²= 144π - this for 360°- and 240° is 96π

but we must add area of the triangle which has two same side and has 6 high so it's area is 6*12√3/2 = 36✓3

our answer is 96π+ 36✓3

$Greetings!$

$I'm~Isabelle~Williams~and~will~be~answering~your~question!$

$I~have~\$1,500 ~in ~my ~investment~ account.~ Rate~ of~ interest ~for~ a\\ ~year~ in~ my ~investment~account = 8.5\$$

$So,~ the~ amount~ of~ money~ I~ am ~making~ on ~my ~investment ~in ~a ~year:$

$=\$\frac{1500\times 8.5}{100}$

$=\$127.5$

______________________________________________________

$I ~owe~ \$ 1600 ~on~ a ~credit~ card .~ Rate ~of ~ interest ~a ~year ~on~ this~ credit\\ card ~debt, = 19 \%$

$So,~ the~ money~ I~ am~ paying~ in~ interest ~in~ a~ year~ on~ my~ card~is:$

$=\$\frac{1600\times 19}{100}$

$=\$304$

______________________________________________________

$Since, ~neither~ I ~withdraw ~money~ from ~my~ investment~ account ~ except~ the\\ ~interest~ nor~ I ~pay~ my~ whole ~credit~ card ~debt~ except ~the ~interest,~ so,~ my~ gain~\\ in~ that~ year:$

$= \$ (127.5 - 304)$

$=\$176.5$

Solve for step by step 5x-2=23

MissTica

You add 2 to 23 which gives you 25. You then divide 5 and 25, which gives you 5.

You volunteer to help drive children at a charity event to the zoo, but you can fit only 7 of the 18 children present in your va

yulyashka [42]

The answer is 19,448 different groups, using the formula from permutation and combinations C (n, r) = (n!) / (r! (n-r)!) which calculates the number of times where r objects can be chosen from n object.

So,

C (17,7) = (17!) / (7! *(17-7)!)

C (17,7) = (17!) / (7! *10!)

C (17,7) = (17*16*15*14*13*12*11*10!) / (7! *10!) then eliminate 10!

C (17,7) = (17*16*15*14*13*12*11) / (7*6*5*4*3*2*1) = (98017920)(5040)

C (17,7) = 19,448 different groups
