Answer:

So you don't overspend.

Step-by-step explanation:

Lets say you bring $10 and everything at the store is half off the price is half of its original (huge savings) and you buy a toy that was $12 and now its $6, if you calculate your own saving you know you have $4 left to spend.


Hope this helps!

Answer:

It is important to be able to calculate discounts yourself because -

It will confirm that the store is reliable enough and that the calculation they made was correct. Also, if we do the calculations mentally or on calculator, we can prepare the money to give at the counter.

A weed called the raindrop vine is known for growing at a very fast rate. It can grow up to 0.75 feet per day. How fast in inche
viktelen [127]

R = rate of growth of raindrop vine = 0.75 feet/day

we know that :  1 feet = 12 inches

1 day = 24 hours

replacing the units accordingly in the above expression for rate of growth of raindrop vine

R = 0.75 (feet/day)  (12 inches/1 feet) (1 day/24 hours)

R = (0.75 x 12 /24) (inches/hour)

R = 0.375 inches/hour

The value of a motorbike depreciates by 32% per year. Work out the current value of a motorbike bought 5 years ago for £3600
DaniilM [7]
\bf \qquad \textit{Amount for Exponential Decay}
\\\\
A=P(1 - r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &3600\\
r=rate\to 32\%\to \frac{32}{100}\to &0.32\\
t=\textit{elapsed time}\to &5\\
\end{cases}
\\\\\\
A=3600(1-0.32)^5\implies A=3600(0.68)^5\implies A\approx 523.41601

Make r the subject of the formula <br>v = \pi \: h {}^{2}(r - \frac{h}{3})v=πh2(r−3h​) <br>​
mel-nik [20]

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} }
