Compute the simple interest earned on a deposit of $5000 at 8.5% for 120 days
ICE Princess25 [194]
Keeping in mind that 120 days is not even a year, since there are 365 days in a year, exluding leap-years, then 120 days is really 120/365 year.

\bf ~~~~~~ \textit{Simple Interest Earned}
\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\to& \$5000\\
r=rate\to 8.5\%\to \frac{8.5}{100}\to &0.085\\
t=years\to \frac{120}{365}\to &\frac{24}{73}
\end{cases}
\\\\\\
I=(5000)(0.085)\left( \frac{24}{73} \right)\implies I \approx 139.72602739726

A total of $228,000 will be evenly spent to renovate 24 apartments. If the first 10 apartments have been completed and paid for,
tigry1 [53]

Step-by-step explanation:

Step 1: <em>Calculate per apartment;</em>

<em>⟼</em> 228,000 ÷ 24

⟼ 9,500

Step 2: <em>Multiply the price per apartment by 10;</em>

⟼ 9,500 × 10

⟼ 95,000

Step 3: <em>Substract the amount of 10 apartments from 24 apartments.</em>

<em>⟼</em><em> </em>228,000 - 95,000

⟼ 133,000

<u>Therefore, </u>$133,000 is still available for the remaining apartments.

Find the quotient. Write your answer in standard form. : 3-i/3+i
s344n2d4d5 [400]
The answer is <span>C. 4/5 - 3/5 i
</span>
\frac{3-i}{3+i} = \frac{(3-i)(3-i)}{(3+i)(3-i)} \\  \\ &#10;(a+b)(a-b) =  a^{2} -b^{2}  \\  \\ &#10;\frac{(3-i)(3-i)}{(3+i)(3-i)}= \frac{ (3-i)^{2} }{3^{2}-i^{2} } \\  \\ &#10;(a-b)^{2} =a^{2}-2ab+b^{2} \\  \\ &#10; \frac{ (3-i)^{2} }{3^{2}-i^{2} } = \frac{3^{2}-2*3*i+i^{2}  }{3^{2}-i^{2} } = \frac{9-6i+i^{2}}{9-i^{2}}  \\  \\ &#10;i =  \sqrt{-1}  \\ i^{2}=-1 \\  \\ &#10;\frac{9-6i+i^{2}}{9-i^{2}} = \frac{9-6i-1}{9+1} = \frac{8-6i}{10}= \frac{8}{10}- \frac{6i}{10}= \frac{4}{5}- \frac{3}{5}i

An airline finds that about 8 percent of the time, a person who makes an advance reservation does not keep the reservation. Ther
Anuta_ua [19.1K]

Answer:

about 9 passengers will not keep theire reservation

Step-by-step explanation:

given that an airline finds that about 8 percent of the time, a person who makes an advance reservation does not keep the reservation

Capacity of the airline per trip = 105 only

But company schedules = 113 people with advance reservations

Since 8% do not turn up

out of 113 passengers who reserved in advance we can say

that 8% of 113 passengers will not keep their reservation

Based on this information, number  of the scheduled people will not keep their reservation

= 8%of 113\\= \frac{8*113}{100} \\=9.04

Since persons cannot be in decimals we can expect about 9 passengers will not keep theire reservation
