Answer:
<u>16.58€</u> considering the most favorable exchange rate to be 1$=0.91€ and the least favorable exchange rate to be 1$=0.91€. The answer cannot be any of the given options as usually there doesn't this much fluctuation occur on a specific day in exchange rate.
Explanation:
By converting the given amount of dollars (US) into Euros in both, most and least, exchange rate on a given day, we can find the saving in Euro for Sandy.
Step-by-step explanation:
Let on a specific day, the most favorable exchange rate was 1$=0.91€ and the least favorable exchange rate was 1$=0.91€. So,
Sandy exchanged the money on the most favorable time and got following amount in Euros:
829.04 * 0.91
=754.43
If Sandy would exchanged the money on the least favorable time on same day then she would have got following amount in Euros:
829.04 * 0.89
=737.85
Hence,
Sandy have 16.58 more euros. As,
754.43-737.85
=16.58€
Answer:
Approximately , assuming that .
Step-by-step explanation:
When the force is constant, moving by in the direction of the force would do a work of .
However, in this example, as an increasing portion of the chain gets lifted up, the force lifting the chain would increase in size. Hence, apply the integral form of this equation.
Let denote the force required to lift the chain when the height above the ground is meters. At that moment, exactly of the chain would be above the ground. The mass of that much of the chain would be the mass of the whole chain.
.
Integrate with respect to :
.
In other words, it would take approximately of energy to raise one end of the chain to that height of .

We can find the slope by using the slope formula. Also know rise over run.
From the slope-intercept y = mx+b.

<u>Answer</u></h3>
Hello there! I can help you! The formula for simple interest is prt. This means that you multiply the principal (the initial amount in the bank), by the rate (simple interest rate) by the amount of time (could be in months or years).
A. Okay. For this problem, we are looking for the amount of interest that will be in the bank after 6 months. We would multiply the time by 0.5, because 6 months is 1/2 a year and 1/2 = 0.5. Let's start off with the 1st account. 4,000 * 5.25% (0.0525) = 210. 210 * 0.5 is 105. There will be $105 in the first account after 6 months. Now, the second one. 2,000 * 6% (0.06) = 120. 120 * 0.5 is 60. There will be $60 in the 2nd account after 6 months. Here are the answers easier to read.
1st account: $105
2nd account: $60
b. To find the difference in the amount of interest earned, just subtract both amounts. 105 - 60 is 45. The difference of the amount of interest earned between the 2 accounts is $45.
c. The 1st account is giving you the most interest out of both accounts. Although it has a lower APR, it gives you the most money, because you have more money in the account initially, than in the 2nd account. When it comes to simple interest, it is calculated, based on the initial amount in the bank. You would have many more dollars in the bank with the first account, and that number would go up as more interest is added.
