Li deposited $17,500 into a bank account that earned simple interest each year. After 2 years, he had earned $2975 in interest.

No money was deposited into or withdrawn from the account.

What was the annual interest rate?

Enter your answer in the box.

Answers

Answer:  8.5%

Step-by-step explanation:

Formula : Simple interest = (Principal) x (annual interest rate) x (Time)    (i)

Given: Principal : P = $ 17,500

Time : 2 years

Simple interest : I = $ 2975

Let r = annual

[tex]2975=17500\times(r)\times(2)[/tex]

[tex]\Rightarrow\ r=\dfrac{2975}{17500\times2}\\\\\Rightarrow\ r=0.085\\\\\Rightarrow\ r=0.085\times100\\\\\Rightarrow\ r=8.5\%[/tex]

Hence, The annual interest rate was 8.5%.

Matthew invested $2,000 in a compound interest account for 3 years. The interest rate was 5%. How much money would it be in the end of third year in Mattew's account?

Answers

Answer:

$2,315.25

Step-by-step explanation:

2000 x 0.05 = 100

2000 + 100 = 2100

After year one: 2100

2100 x 0.05 = 105

2100 + 105 = 2205

After year two: 2205

2205 x 0.05 = 110.25

2205 + 110.25 = 2315.25

After year three: 2315.25

Which decimal represents the portion that is NOT shaded?

0.003

0.03

0.3

3.0

Write how u solved it
​

Answers

Answer:

0.3

Step-by-step explanation:

Answer:

3.0

Step-by-step explanation:

Here we have a rectangle split into ten parts with 7/10 shaded in blue. The question asks what decimal represents the portion, alright, let's go down the list.

0.003 is also known as 3 thousandths, meaning that we would need a thousand little squares as our figure. Clearly this isn't the case, so 0.003 is wrong.

0.03 is also known as 3 hundredths, meaning  that we would need a hundred little squares as our figure, this also isn't the case, so 0.03 is wrong.

0.3 is known as 3 tenths, yes this could represent our figure, but it doesn't represent the finished portion, which would be 1.0, this means that only one part will be shaded in the figure we have now, leaving it to be wrong.

This leaves us with 3.0

Mike can run a mile in 12 minutes. He starts at 11:30 AM. and runs 4 miles. What time does Mike finish his run at?

Answers

Answer: Mike stops running at 12:18 PM

Step-by-step explanation: We know he runs 1 mile each 12 minutes and we also knows he ran 4 miles so the equation is 12*4 or (12 times 4) which is equal to 48. We then add 38 minutes to 11:30 AM and end up at 12:18 PM.  

Answer:

12:18 P.M

Step-by-step explanation:

So the first thing I did was find out the amount of time it takes Mike to run 4 miles by multiplying 12 x 4 = 48

So Mike spends 48 minutes running the 4 miles.

Now we add 48 minutes to 11:30. So since there is no such thing as 11:78 I first subtracted the 30 minutes from the 48 minutes and added that to 11:30 which gave me 12:00 pm and then I just added the reamaining18 minutes.

which in conclusion means,

Mike will finish his 4 miles at 12:18 P.M

Survi purchased 2 balls for 20.34, 8 pencils for Rs. 24.08, and a copy for Rs.5.08. She gave an Rs.50 note to the shopkeeper and asked him to keep the change. What amount did the shopkeeper keep? *

Answers

Add the total of the 3 things bought and subtract from what they gave the cashier:

20.34 + 24.08 + 5.08 = 49.50 total

50 - 49.50 = 0.50

The shopkeeper kept 0.50

Find each amount:



3.8% of 25

Answers

Answer:

0.95

Step-by-step explanation:

3.8 % of 25 is equal to 0.95.

To find 3.8 % of 25, we can calculate it using the following formula : Amount = ( Percentage / 100 ) * Base.

In this case, the percentage is 3.8 and the base is 25.

Using the formula , we have : Amount = ( 3.8 / 100 ) * 25.

First, we divide 3.8 by 100, which gives us 0.038. Then, we multiply 0.038 by 25 to find the amount.

Calculating, we have : Amount = 0.038 * 25 = 0.95.

Therefore, The value of 3.8 % of 25 is equal to 0.95.

Moisture hung in the air so thick you could almost see it sparkling in the dim sunlight. There were days, early in the summer like this one, where it seemed there was more water in the air than in the bay. We had beached the boat and stepped out on the recently cleared spit of land. The ground had a light dusting of white sand over an under layer of dried black mud. It looked like a recently frosted chocolate cake, though the frosting was spread a bit thin for my taste. The ground was solid, but we knew from experience that it was full of fiddler crab holes, and would be underwater at the first super-high tide. Mysteriously, to us anyway, someone wanted to build a house there.We often came to these spots to look for artifacts. Our beach, our summer home, had been a fishing camp for as long as anyone living could remember. The oldest stories told of travelers coming down to the edge of the sea, lining up to fill their wagon beds with salted fish to take back home. Old decaying cabins still lined the beach. Rotting nets, hung out to dry in the last century, decorated their weathered walls. Their broken faces spun stories in our minds. The fishermen who, tanned and wrinkled from sun and salt, hauled their nets full of splashing mullet in to cheers from the waiting crowds. The bounty of the sea lightened everyone's hearts, and the smell of roasting fish filled the damp air. Women fanned themselves from wagon seats. Children splashed in the shallow edges of the bay.
