Anna starts a fixed deposit with $178000, the bank offers 9.5% per year simple interest for 8 months. she has the option of restarting the investment using the interest earned as principal or cashing out at the end of the 8 months, (A) Calculate the interest due after 8 months. (B) if she restarts the investment into a new one calculate the total value of the investment at the end of the second 8 months

Answers

Using simple interest, we have that:

A) The interest due after 8 months is $11,272.33.

B) The total value of the investment will be of $189,986.24.

The amount of interest earning using simple interest, after t years, with an yearly interest rate of i and an initial investment of P is given by:

[tex]E = Pit[/tex]

In this problem:

Deposit of $178,000, hence [tex]P = 178000[/tex].Interest rate of 9.5% per year, hence [tex]i = 0.095[/tex].8 months, the time is in years, hence [tex]t = \frac{8}{12} = \frac{2}{3}[/tex]

Item a:

[tex]E = Pit[/tex]

[tex]E = 178000(0.095)\frac{2}{3} = 11272.33[/tex]

The interest due after 8 months is $11,272.33.

Item b:

For the second interest, we consider [tex]P = 11272.33[/tex], hence:

[tex]E_2 = Pit[/tex]

[tex]E_2 = 11272.33(0.095)\frac{2}{3} = 713.91[/tex]

The total value will be composed by:

The initial deposit of $178,000.The first interest of $11,272.33.The second interest of $713,91.

Hence, it will be:

[tex]T = 178000 + 11272.33 + 713.91 = 189986.24[/tex]

The total value of the investment will be of $189,986.24.

Rohan spent 20% of his pocket money on transport and ₹60 on his breakfast.If he spent 15% of the remaining money on his lunch and had ₹340 left, what was his pocket money?​

Answers

He spent on transport = 20%

spent on breakfast = 60/-

spent on lunch = 15%

remaining amount = 340

rs he spent on transport = 20/100 × 340 =68

rs he spent on lunch = 15/100 × 340 = 51

Therefore, total of his pocket money = 68 + 51 + 60 + 340

There are four groups of 20 people walking on a shrew each person walks 3 miles how many total miles do all of the people walk

Answers

The answer is 240 miles. 3(4)(20) = 240

All the peoples in a group walk 240 miles.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

There are 4 groups of 20 peoples.

And, Each person walk 3 miles.

Now,

Since, There are 4 groups of 20 peoples.

So, Total number of peoples in 4 groups = 4 x 20

                                                               = 80

And,  Each person walk 3 miles.

So, The distance cover by 80 peoples = 80 x 3

                                                           = 240 miles.

Thus, All the peoples in a group walk 240 miles.

Answers

Answer:

If Bryan can run 2 miles in 20 minutes, he can run 10 miles in 100 minutes.

Step-by-step explanation:

To determine the answer to this problem, we can first find how many minutes it takes Bryan to run one mile. Because it takes him twenty minutes to run two miles, it must take Bryan ten minutes to run one mile.

1 mile = 10 minutes

Multiply this by ten to find how many miles Bryan runs in 100 minutes.

10 miles = 100 minutes

Bryan can run 10 miles in 100 minutes.

Answer: 10 miles

Step-by-step explanation: They’re equivalent to the minutes. 20 minutes 2 miles, 40 minutes 4 miles and so on.

Hummingbirds were flying around heliconia stalks, Parrots were flying overhead, and macaw birds were singing in the treetops. It sounded like there was a waterfall nearby. It smelled like it had just rained, and there in the center of the room there was a large stone by a steady stream that Violet was meditating on. Violet suddenly saw Conner and said Computer, end program. Hey Violet, said Conner weve got to go. Where Conner? said Violet To mars silly, said Conner Conner, Violet said, are you sure its safe on mars? Im positive Violet said Conner let us go tell the captain we are ready. Alright, said Violet Computer, teleport us to the Captain.Violet and Conner were instantly transported to the captains quarters. The captain looked surprised to see them at first but smiled when she saw it was Violet and Conner. Hello Violet, Hello Conner, said Captain Jane Picard I see you two must have made up your minds, what is your final answer? We are going! said Violet and Conner in unison. Good said Captain Picard Computer, Transport Violet and Conner to mars. Suddenly there was a loud explosion, then Violet and Conner were on Mars.Standing ever so elegantly in front of Violet and Conner was a palace made of blue and purple Martian crystals, with flags made of golden silk and embroidered with diamond thread that shined like the stars. Violet and Conner went inside the palace, and there were two thrones, one of pink Martian crystals with a white diamond heart engraved on it and one of blue Martian crystals with a red ruby sword engraved on it. what do those symbols mean Violet? said Conner They mean love and war. said Violet weird said Conner why would thrones have the symbols of love and war.
