Christine has $875.83 In her savings account the account pays 9% compounded monthly. Christine does not make any deposits or withdrawals over the next six months how much interest does the account earn

Answers

Answer: the account earns interest of $40.16

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = 875.83

r = 9% = 9/100 = 0.09

n = 12 because it was compounded 12 times in a year.

t = 6 months = 6/12 = 0.5 year

Therefore,.

A = 875.83(1+0.09/12)^0.5 × 12

A = 875.83(1+0.0075)^6

A = 875.83(1.0075)^6

A = 915.99

The interest that she earns is

915.99 - 875.83 = $40.16

you are purchasing jeans and t-shirts. jeans cost $35.and t-shirt costs $15. you plane on spending $115 and purchasing a total of 5 items. how many pairs of jeans and how many t-shirt will you buy

Answers

The answer is
2 jeans
3 t-shirts
Because jeans are £35 so £35x2=£70
T-shirt are £15 so £15x3=£45
£45+£70=£115

A bus travels through the city and stops every mile. The first stop on the route is the 8th Avenue Coffee Shop, which is located 15 blocks east and 22 blocks north of the central station. The last stop on the route is the airport, which is located 25 blocks west and 36 blocks south of the central station. A student calculated the middle stop along the bus route to be located 20 blocks east and 29 blocks north of the central station. Evaluate the student’s answer.

Answers

Answer:Student calculation is incorrect

Step-by-step explanation :

Given the First stop is the 8th Avenue Coffee Shop, which is located 15 Blocks east and 22 blocks north of the central station

and the last stop on the route is 25 blocks west and 36 blocks south of the central station .

Lets take the First stop co-ordinates be (15,22)

and last stop co-ordinates (-25,-30)

So there mid-point is $x=(x_1+x_2)/(2)$

$y=(y_1+y_2)/(2)$

$x=(15-25)/(2)=-5$

$y=(22-30)/(2)=-4$

Therefore middle stop is 5 blocks west and 4 blocks South

Thus calculated the middle stop incorrectly.

The student apparently added numbers without taking into account direction. They seem to have added 15 and 25 and divided by 2 to get the horizontal component of the middle stop when they should have added 15 and -25 and divided by 2. A similar mistake was made on determining the vertical component. The middle stop should have been calculated as 5 blocks west and 7 blocks south of the central station. So your answer is C.

What is the common ratio of the following sequence?
80, 20, 5,

Answers

The value of the common ratio of the sequence is,

⇒ 1 / 4

What is Geometric sequence?

An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.

Given that;

The sequence is,

⇒ 80, 20, 5,...

Now, We can find as;

The value of the common ratio of the sequence is,

⇒ 20 / 80

⇒ 1 / 4

Thus, The value of the common ratio of the sequence is,

⇒ 1 / 4

38% convert into fraction

Answers

To convert a percentage into a fraction, we must first convert the percentage into a decimal. We can do that by either dividing the percentage by 100, or (my personal shortcut) just shifting the decimal point over two places to the left.

38% = 0.38

Now, all we need to do to convert it into a fraction is put the numbers to the right of the decimal point above a multiple of ten with as many zeros as there are numbers to the right of the decimal point. In this case:

0.38 = $(38)/(100)$

Now, all we need to do is reduce to find our fraction.

38 and 100 are both divisible by 2, so we will start off by doing that.

$(38 / 2)/(100 / 2) = (19)/(50)$

And that is our answer.
38% in fraction form is $(19)/(50)$ .
