I put $500 in a saving account that earns 6% interest compounded semi-annually. How much interest will be in the account after 2
Nuetrik [128]
\bf ~~~~~~ \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$500\\
r=rate\to 6\%\to \frac{6}{100}\to &0.06\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{semi-annually, thus twice}
\end{array}\to &2\\
t=years\to &2
\end{cases}
\\\\\\
A=500\left(1+\frac{0.06}{2}\right)^{2\cdot 2}\implies A=500(1.03)^4\implies A=562.754405

now, "A" is the accumulated amount, including the earned interest, how much interest was it earned?  well, is just A - P.

What is the solution for d+35.5=52?
faust18 [17]

Answer:

d = 16.5

Step-by-step explanation:

Add -35.5 to both sides of the equation, then simplify.

... d + 35.5 - 35.5 = 52 - 35.5

... d + 0 = 16.5

... d = 16.5

_____

In general, if something unwanted is added, adding the opposite will undo that operation.

A car travels 440km in 15.4 hours -> In 1 hour, the car travel 1/(15.4) the distance.

So in an hour, the car travel : 440 x 1/(15.4) = 28.5714285714... (round to 29)

So, the average speed of the car is approximately 29 km/h

What is the solution to the inequality -2.1x + 2.9 > 15.5?
LenKa [72]

Answer:

x<−6

Step-by-step explanation:

Let's solve your inequality step-by-step.

−2.1x+2.9>15.5

Step 1: Subtract 2.9 from both sides.

−2.1x+2.9−2.9>15.5−2.9

−2.1x>12.6

Step 2: Divide both sides by -2.1.

−2.1x−2.1>12.6−2.1

x<−6
