A certain bank pays 3.4% interest per year for a certificate of deposit, or
CD. What is the total balance of an account after 18 months with an initial
deposit of $1,250?

a. 765$
b. 2,015$
c. 63.75$
d. 1,313.75$

Answers

STEP BY STEP

A = $1,313.75

Equation:
A = P(1+rt)

Calculation:

First converting R percent to R a decimal
R = r/100 = 3.4%/100 = 0.034 per year.

Putting time into years for simplicity,
18 months / 12 months/ year = 1.5 years

Solving our equation:
A = 1250(1+[0.034 * 1.5]) = $1,313.75

The total amount accrued, principal plus interest, from simple interest on a principal of $ 1,250.00 at a rate of 3.4% per year for 1.5 years (18 months) is $1,313.75

The ANSWER would be

D. $1.31375

$[tex]1,313.75[/tex] is the total balance of an account after [tex]18[/tex] months with an initial deposit of $[tex]1,250[/tex]

What is balance?

In banking and accounting, the balance is the amount of money owed on an account. In bookkeeping, “balance” is the difference between the sum of debit entries and the sum of credit entries entered into an account during a financial period. When total debits exceed total credits, the account indicates a debit balance.

What is Interest?

In finance and economics, interest is payment from a borrower or deposit-taking financial institution to a lender or depositor of an amount above repayment of the principal sum, at a particular rate. It is distinct from a fee which the borrower may pay the lender or some third party.

According to questions, a certain bank pays [tex]3.4[/tex]% interest per year for a certificate of deposit, or CD.

We have to find the total balance of an account after [tex]18[/tex] months with an initial deposit of $[tex]1,250[/tex]

Total balance can be calculated using the following formula:

[tex]A = P(1+rt)[/tex]

Here [tex]r=\frac{3.4}{100} =0.034[/tex]

[tex]t=\frac{18}{12} =1.5[/tex]

So,[tex]A = 1250(1+0.034[/tex]×[tex]1.5[/tex])

[tex]=[/tex]$[tex]1,313.75[/tex]

Therefore,$[tex]1,313.75[/tex] is the total balance of an account after [tex]18[/tex] months with an initial deposit of $[tex]1,250[/tex]

Hence, we can conclude that Option(d) is correct.

z = - 300

Step-by-step explanation:

Flip the equation so it looks like: 0.07z = -21

Then, divide it by 0.07 on both sides, which gets you -300.

You could also divide it by 7 and then multiply that answer by 100 if you want an extra step

Multiply length (l) x width (w) on each section. 45x5 = 225

10 x 10 = 100 and 6 x 10 = 60/2 = 30 (since it is a triangle you divide by two)

Add them all up, 225 + 100 + 30 = 355 square inches

Answer:

A. 355 in.²

Step-by-step explanation:

45 × 5 = 225

10 × 10 = 100

Triangle with a 10 in. base and 6 in. height = 30

225 + 100 + 30 = 355 in.²

Answer:

x = 14

y = 39

A. 114F degrees

Step-by-step explanation:

well for the first one they're asking for a simliar ratio to show the relationship between all of the points

so we must line up and simplify all the points to try and find a simliar ratio

so the ratio is 2/3

because if we simplify 8/12 and 16/24 they both come down to 2/3

so if we plug that in to find x we get x = 14

and then if we that in for y we get y = 39

now for the second question this is a pretty simple addiction subtraction kind of problem but here's some help

if the highest temperature was 93 and the lowest was -21 we just have to find how many degrees are in between those two

therefore leaving us with the answer

A. 114F degrees

In this extract, the narrator discusses what his life is like now, long after a traumatic ordeal with a ghostly woman who stole the life of his only son.CHRISTMAS EVEIt was nine-thirty on Christmas Eve. As I crossed the long entrance hall of Monks Piece on my way home from the dining room, where we had just enjoyed the first of the happy, festive meals, towards the drawing room and the fire around which my family were now assembled, I paused and then, as I often do in the course of an evening, went to the front door, opened it and stepped outside.I have always liked to take a breath of the evening, to smell the air, whether it is sweetly scented and balmy with the flowers of midsummer, pungent with the bonfires and leaf-mould of autumn, or crackling cold from frost and snow. I like to look about me at the sky above my head, whether there are moon or stars or utter blackness, and into the darkness ahead of me; I like to listen for the cries of nocturnal creatures and the moaning rise and fall of the wind, or the pattering of rain in the orchard trees, I enjoy the rush of air towards me up the hill from the flat pastures of the river valley.Tonight, I smelled at once, and with a lightning heart, that there had been a change in the weather. All the previous week, we had had rain, chilling rain and a mist that lay low about the house and over the countryside. From the windows, the view stretched not farther than a yard or two down the garden. It was wretched weather, never seeming to come fully light, and raw, too. There had been no pleasure in walking, the visibility was too poor for any shouting and the dogs were permanently morose and muddy. Inside the house, the lamps were lit throughout the day and the walls of larder outhouse and cellar oozed damp and smelled sour, the fires sputtered and smoked, burning dismally low.My spirits have for many years now been excessively affected by the ways of the weather, and I confess that, had it not been for the air of cheerfulness and bustle that prevailed in the rest of the house, I should have been quite cast down in gloom and lethargy, unable to enjoy the flavour of life as I should like and irritated by my own susceptibility. But Esme is merely stung by inclement weather into a spirited defiance, and so the preparations four our Christmas holiday had this year been more than usually extensive and vigorous.I took a step or two out from under the shadow of the house so that I could see around me in the moonlight. Monks piece stands at the summit of land that rises gently up for some four hundred feet from where the little River Nee traces its winding way in a north to south direction across this fertile, and sheltered, part of the century. Below us are pastures, interspersed with small clumps of mixed, broadleaf woodland. But at our backs for several square miles it is quite a different area of rough scrub and a heathland, a patch of wildness in the midst of a well-farmed country. We are but two miles from a good-sized village, seven from the principal market town, yet there is an air of remoteness and isolation which makes us feel ourselves to be much further from civilization Solve for the variable-7 + m = -15 sym sum i need helps do siwbdi im doing this for the points lol Jill owns a salon and she submit a PPP loan application .
