How much money is earned by investing $10,000 for 5 years and 3 months at 3 1/5% annual interest, compounded monthly? (I know how to do this but how do you put "5 years and 3 months" into a formula and how do you add it up to make 525?)

Answers

Answer:

$\$11,826.72$

Step-by-step explanation:

we know that

The compound interest formula is equal to

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

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$P=\$10,000\nn=12$

$t=5\ years\ 3\ months=5+(3)/(12)=5.25\ years$

$r=3(1)/(5)\%=(3+(1)/(5))\%=3.2\%=3.2/100=0.032$

substitute in the formula above

$A=10,000(1+(0.032)/(12))^(12*5.25)$

$A=10,000((12.032)/(12))^(63)$

$A=\$11,826.72$

Answer:

Actually, The top answer is wrong... The answer would be $1,826.72 ( Sorry...not trying to be rude or anything)

Jem boy wants to make his 8-meter square pool into a rectangular one by increasing its length by 2m and decreasing its width by 2m .jem boy asked your expertise to help him decide on certain matters.a.What will be the new dimensions of jem boy's pool?
b.What will be the new are of Jem Boy's pool? What special product will be used?
c.If the sides of the square pool is unknown,how will you represent its area?
d. I fJem Boy does not want the area of his pool to decrease, will he pursue his plan? Explain your answer.

Answers

Side = 8m
He increases length by 2m and reduces width by 2m
(a.) New dimensions will be -
Length = 10m and Width = 6m
(b.) Area = length x breadth (or width)
here we will use the special product (x+y) (x-y)
length = (x+y) and width = (x-y)
area = (8+2) x (8-2)
8^(2) - 2^(2)
= 60

The sum of two consecutive integers is -15. If1 is added to the smaller integer and 2 is
subtracted from the larger integer, what is the

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The product of the two resulting integers is 80.

What is multiplication?

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Let the unknown integer be represented by x. Given that the sum of two consecutive integers is -15. Therefore, we can write,

x + (x+1) = -15

2x + 1 = -15

2x = -16

x = -8

Thus, the smaller integer is -9 and the larger integer is -8.

Now, If 1 is added to the smaller integer and 2 is subtracted from the larger integer.

Smaller Interger = -9 + 1 = -8

Larger Integer = -8 - 2 = -10

Further, the product of the two resultingintegers is,

Product = -8 × -10

= 80

Hence, the product of the two resulting integers is 80.

Determine whether the quantities in the problem vary directly or inversely and then solve the problem. A mill processes 48 tons of flour in 15 hours. How many tons of flour can the mill process in 20 hours if its rate or production stays the same?

Answers

Answer:

Step-by-step explanation:

U have a direct proportion

48 tons of flour to 15 hrs = x tons of flour to 20 hrs

48 x

------- = ------- cross multiply

15 20

(15)(x) = (48)(20)

15x = 960

x = 960/15

x = 64 <==== 64 tons

Forty is 25% of what number?

Answers

Since it is 25% all you would have to do is mutiply it by 4 to get 160. So in conclusion 160 is the answer.

40 is 25% of 160 because 25% is the same as 1/4 and 1/4 of 160 is 40

London Heathrow airport see on average 191,200 passengers a day how many passengers is this per minute. I need to show the steps to my answer

Answers

First you have to ask, how many minutes are in a day?
There are 60 minutes in a hour, and 24 hours a day. You would multiply these two to find how many minutes are in a day.

24×60=1440 minutes in a day.

Now to find how many passages a minute, divide the total number of passangers, by the number of minutes.
191,200÷1440=132.7778

Even though the 7 is bigger than a 5, you do not round up because it doesn't count as a full person.
132 people a minute is your answer.
