The total value of an investment was $305.33 after $240 was invested for 10 years compounded monthly. Find the interest interest rate.

Answers

Answer:

Interest rate = 2.41%

Step-by-step explanation:

The total value of an investment was $305.33 after $240 was invested for 10 years compounded monthly. Find the interest rate.

The formula to calculate the Interest rate for a Compound Interest is given as:

Solving for rate r as a decimal

r = n[(A/P)^1/nt - 1]

r = 12 × [(305.33/240.00)^1/(12)(10) - 1]

r = 0.0240996

Then convert r to R as a percentage

R = r * 100

R = 0.0240996 * 100

R = 2.41%/year

Therefore, the Interest rate = 2.41%

The time required to drive a fixed distance varies inversely as the speed. It takes 40 hr at a speed of 10 km/h to drive a fixed distance. How long will it take to drive the same distance at a speed of 8 km/h?

Answers

Answer:

50 hours

Step-by-step explanation:

Given data

Time=40hr

Speed=10km/hr

Let us find the fixed distance first

Speed= distance/Time

10= distance/40

distance= 10*40

distance= 400miles

Now our speed= 8km/h

hence the time is

8= 400/time

time= 400/8

time=50 hours

Hence the time is 50 hours

Jackson is starting an exercise program.The first day he will spend 30 minute on a treadmill by 2 minutes each day.Write an equation for t(d),the time,in minutes,on the treadmill on day d

Answers

Answer:

For the d day Jackson exercised for t(d)=  30 + 2d where d is the number of day.

t(d)= 30 + 2d

Step-by-step explanation:

Let the total time on the treadmill be given by y each day and let x take the values of number of the days exercised . For the first day x= 0  and so on.

Therefore

For the first day Jackson exercised for  30 minutes

y= 30 + 2x

y= 30 + 2(0)

y= 30 minutes

For the second day Jackson exercised for (x=1) 32 minutes

y= 30 + 2x

y= 30 + 2(1)

y= 32 minutes

For the third day Jackson exercised for (x=2) 34 minutes

y= 30 + 2x

y= 30 + 2(2)

y= 34 minutes

For the fourth day Jackson exercised for (x=3) 36 minutes

y= 30 + 2x

y= 30 + 2(3)

y= 36 minutes

For the d day Jackson exercised for (x=d) 30 + 2d where d is the number of day.

y= 30 + 2x

y= 30 + 2(d)

y= 30 + 2d

Read the following excerpt from The Story of My Life by Helen Keller and then answer the question that follows.The morning after my teacher came she led me into her room and gave me a doll. The little blind children at the Perkins Institution had sent it and Laura Bridgman had dressed it; but I did not know this until afterward. When I had played with it a little while, Miss Sullivan slowly spelled into my hand the word "d-o-l-l." I was at once interested in this finger play and tried to imitate it. When I finally succeeded in making the letters correctly I was flushed with childish pleasure and pride. Running downstairs to my mother I held up my hand and made the letters for doll. I did not know that I was spelling a word or even that words existed; I was simply making my fingers go in monkey-like imitation. In the days that followed I learned to spell in this uncomprehending way a great many words, among them pin, hat, cup and a few verbs like sit, stand and walk. But my teacher had been with me several weeks before I understood that everything has a name. I left the well-house eager to learn. Everything had a name, and each name gave birth to a new thought. As we returned to the house every object which I touched seemed to quiver with life. That was because I saw everything with the strange, new sight that had come to me.Which of the following best summarizes the excerpt?1. Helen's teacher taught her to finger spell doll so she knew how to tell her teacher what toy she wanted to play with.2. Helen's teacher taught her all objects have a name opening the world of language.3. Helen liked to touch all the objects in the house so she knew which ones she wanted to play with.4. Helen was excited to learn that everything had a name so that she could talk with her teacher. pls, help me!There are 10 pieces of paper numbered 1 through 10.
