Tracy deposited $59 into a bank account that earned 3.5% simple interest each year. If no money was deposited into or withdrawn
Illusion [34]

Answer

Find out the how much money was in the account after 1\frac{1}{2} years.

To prove

Formula

Simple\ interest = \frac{Principle\times Rate\times time}{100}

As given

Tracy deposited $59 into a bank account that earned 3.5% simple interest each year.

Principle = $59

Rate = 3.5 %

Time = 1\frac{1}{2}

i.e

Time = \frac{3}{2}

Time = 1.5 years

Put all the values in the equation

Simple\ interest = \frac{59\times 3.5\times 1.5}{100}

                                 =  \frac{309.75}{100}[/tex]

                                = $3.1(approx)

Amount in the account = Principle + Simple interest

                                      = $59 + $ 3.1

                                      = $ 62.1

1 Dollar = 100 cent

Now convert $62.1 into cent.

= 62.1 × 100

= 6210 cent

Therefore the money in the account is 6210 cent .

AlladinOne [14]

He'll spend 138.91 dollars.

First multiply 427 and 231 to find out how much square feet you need to cover. Then divide the number by 3500 to see how many bags of fertilizer you need. Since there is a remainder, he'll have to buy another bag. Then, multiply the number of bags needed with the price of each bag to get the amount of money spent.

The product of these slopes is ______.This product shows that the slopes are negative reciprocals. It is given that the lines ar
Arturiano [62]

Answer:

- 1

Step-by-step explanation:

Let the slope of one line be 's' , then according to the given condition that the  slope of second line is negative reciprocal of the first , We obtain the slope of the second line as \frac{-1}{s}.

So, the product of both the slopes is given by s\cdot \frac{-1}{s}=-1

This shows that whatever the slopes may be if they are negative reciprocal of each other then their product will always be -1
