Okay, I got you...

2) 2

3) 6

4) 33

5) 5

6) 19

No. (12+6)/2=9

and 12+6/2=15

This happens because in order of operations parentheses come first, so you would do that and get 18. Then you would divide 18 by 2 and get 9.

On the second one you would do division first (6/2) and get three, the you would add 12 and end up with 15.

Hope this helps :)

Answer:

\boxed{r =  \frac{h}{3}  +  \frac{v}{\pi {h}^{2} } }

Step-by-step explanation:

Solve \:  for \:  r:  \\  =  >   v= \pi {h}^{2}(r -  \frac{h}{3}  ) \\  \\  v=\pi {h}^{2}(r -  \frac{h}{3}  )is \:  equivalent  \: to   \:   {h}^{2}\pi(r -  \frac{h}{3}  ) = v: \\  =  >  {h}^{2}\pi(r -  \frac{h}{3}  ) = v \\  \\ Divide  \: both \:  sides  \: by  \: \pi  {h}^{2} :  \\  =  > r -  \frac{h}{3}  =  \frac{v}{\pi {h}^{2} }  \\  \\ Add \:   \frac{h}{3}  \:  to  \: both \:  sides:  \\  =  > r =  \frac{h}{3}  +  \frac{v}{\pi {h}^{2} }

kolbaska11 [484]

Answer:

$216435

Step-by-step explanation:

Given : Suppose homes in a big city increase in value 13% every year.

To Find: How much will a home that cost $150,000 be worth 3 years later?

Solution:

Principal = $150000

Rate = 13% =0.13

Time = 3 years

Formula : A=P(1+r)^t

Now substitute the values in the formula

A=150000(1+0.13)^3

A=216434.55

So, The cost of home after 3 years will be $216435

Hence Option B is true
