What is the interest rate of each investment if The annual interest on a $17,000 investment exceeds the interest earned on an $8
Butoxors [25]

<u>Solution-</u>

Let's assume, the rate of interest of $8000 is x%,

then the rate of interest of $17000 is (x+0.3x) =1.3x%

Interest earned by $8000,

i_1=\frac{8000\times x\times 1}{100} =80x

Interest earned by $17,000,

i_2=\frac{17000\times 1.3x\times 1}{100} =221x

According to the question,

\Rightarrow i_1=i_2+276

\Rightarrow 221x=80x+276

\Rightarrow 221x-80x=276

\Rightarrow 141x=276

\Rightarrow x=1.96

∴ Rate of interest of $8000 is 1.96% and rate of interest of $17000 is (1.3×1.96) =2.55%

A rectangular solid has sides of 7 cm + 9 cm + 11 cm what<br> is its surface area
alina1380 [7]

Your answer would be: <em>693.</em>

Explanation:

When finding the area in a problem use <em>L×W×H</em>.

That being said, you now have to multiply the <em>L×W×H</em> (7x9x11)

7 × 9 × 11 = <em>693</em>

So the answer would be <em>693</em> because, if you are finding an area you use <em>L×W×H</em> to find your area.
