Last year, Kevin had 20,000 to invest. He invested some of it in an account that paid 6% simple interest per year, and he invest

tester [92]

$13,000 was invested at 6% whereas $7,000 was invested at 10% using simple interest approach

What is simple interest?

Simple interest is determined as the amount invested multiplied by the interest rate and the number of years that investment lasts.

I=PRT

I=interest

P=principal

R=rate of return

T=time

Let X be the amount invested at 6%

I at 6%=6%*X*1

I=0.06X

The amount invested at 10% is 20,000-X

total interest=0.06X+0.10*(20000-X)

total interest=1,480

1480=0.06X+0.10*(20000-X)

1480=0.06X+2000-0.10X

1480-2000=0.06X-0.10X

-520=-0.04X

X=-520/-0.04

X=13,000

13,000 was invested at 6%

amount invested at 10%=20,000-X

amount invested at 10%=20,000-13,000

amount invested at 10%=7,000

In a survey of 2000 people, 50% of them visited the country A and 40% of them

denis23 [38]

Step-by-step explanation:

n (U)=2000

n (A)=50% of 2000

=(50÷100)×2000

= 1000

n( B) = 40%

= (40÷100)×2000

= 800

n(AuB)(compliment) = 15%

=(15÷100)×2000

=300

A regular hexagon has a perimeter of 70 m. Find its area. Leave your answer in simplest radical form.

Semmy [17]

A HEXA=6, gon, has 6 sides, and we know the perimeter, all sides added up, is 70, so one side is just 70/6, or 35/3

$\bf \textit{area of a polygon}\\\\
A=\cfrac{1}{4}ns^2\ cot\left( \frac{180}{n} \right)\qquad 
\begin{cases}
n=\textit{number of sides}\\
s=\textit{length of one side}\\
\frac{180}{n}=\textit{angle in degrees}\\
----------\\
n=6\\
s=\frac{35}{3}
\end{cases}
\\\\\\
A=\cfrac{1}{4}\cdot 6\cdot \left( \frac{35}{3} \right)^2\cdot ot\left( \frac{180}{6} \right)$
