HELP!!!!!
frosja888 [35]

Answer:

I think it is 350(1.2)^t because you take the starting amount (350) and then multiple it by the growth rate (which is 20%, but when added to 100 and the put into a decimal is 1.2) raised by the number of hours (t).

I hope this helps.

Find the circumference of a circle whose area is 24 pi ft ^2
lianna [129]
\bf \textit{area of a circle}\\\\&#10;A=\pi r^2~~&#10;\begin{cases}&#10;r=radius\\&#10;-----\\&#10;A=24\pi &#10;\end{cases}\implies 24\pi =\pi r^2\implies \cfrac{24\pi }{\pi }=r^2&#10;\\\\\\&#10;24=r^2\implies \boxed{\sqrt{24}=r}\\\\&#10;-------------------------------\\\\&#10;\textit{circumference of a circle}\\\\&#10;C=2\pi r\qquad \qquad \implies C=2\pi\left( \boxed{\sqrt{24}} \right)~~&#10;\begin{cases}&#10;24=2\cdot 2\cdot 2\cdot 3\\&#10;\qquad 2^2\cdot 6&#10;\end{cases}&#10;\\\\\\&#10;C=2\pi \sqrt{2^2\cdot 6}\implies C=2\pi (2\sqrt{6})\implies C=4\sqrt{6}~\pi

How do solve 4v-13-10v=12-24v+5
yaroslaw [1]
You get all the v's on one side by adding 24v to both sides
4v-13-10v = 12-24v +5
+24v +24v
And then you would get
4v-13-10v+24v = 12+5
Then combine like terms
18v-13=17
Then you would get v alone by adding 13 to both sides
18v-13= 17
+13 +13
That would give you
18v=30
Then divide both sides by 18 to get your final answer
18v = 30
/18 /18
Your final answer is...
V=1.66

When a=1/4 and b=10.

We simply substitute the given values of as and b into the given expression,

8a-1+0.5b=8(\frac{1}{4}) -1+0.5(10)\\=2-1+5\\=6
