What is compound interest depreciation?Depreciation is essentially a compound measure in the opposite direction, so decreasing the original value at a specific percentage at regular intervals. For depreciation you need to use the multiplier method for decreasing percentages and put this multiplier to the power of the number of time intervals in the question.
Formula of compound interest depreciation :
[tex]A= P(1-\frac{r}{100} )^{n}[/tex]
Where,
A = final amount
P = initial principal
n = time in years
r = rate per annum
According to the question
A population of fish starts at (P)= 8000
decreases per year (r) = 6%
n = 10
now , Applying Formula of compound interest depreciation :
[tex]A= P(1-\frac{r}{100} )^{n}[/tex]
substituting the value
[tex]A= 8000(1-\frac{6.4}{100} )^{10}[/tex]
[tex]A= 8000(0.936} )^{10}[/tex]
A=8000 * 0.5161
A = 4,129.03 (approx.)
A = 4129 (round off to nearest whole no )
Hence, the population of fish at the end of 10 years will remain 4129 .

Line a and b are perpendicular lines.If line a is represented by y=s/t x+10 and line b is represented by y=q/r -4 where s,t,q and r are integers and t and r are not equal to zero which statement is always true
Answer:
The options are not shown, so i will answer in a general way.
First, for a line of the form:
y = a*x + b
All the perpendicular lines will have a slope of -(1/a), then we can write a general perpendicular line as:
y = -(1/a)*x + c.
In this problem we have the perpendicular lines:
y=(s/t)*x+10
y = (q/r)*x - 4
Because those lines are perpendicular, we must have that:
(q/r) = -(1/(s/t)) = -(t/s)
q/r = -t/s
and we knew that s, t, q and r are integers (where t and r can not be equal to zero), and because of this relation, where we can see that in the denominator at the right we have the integer s, we can conclude that s can not be zero (we can not divide by zero).
And we know that t and s are both different than zero, then:
-t/s ≠ 0.
This means that:
q/r ≠ 0
And from this, we can conclude that q is different than zero.

A pair similar to 3 red to 1 blue is 6 red to 2 blue. Since there are already 4 red and 2 blues, then you just add 2 reds. Hope that helps!
Answer:
D. 2 red, 0 blue
Step-by-step explanation:
You already have 4 red, 2 blue. If you add 2 red, 0 blue, you have 6 red, 2 blue. If you divide both amounts by 2, (6 divided by 2, 2 divided by 2) you get 3 red, 1 blue.

Write a linear function with the values f(6)=8 and f(9)=3
*PLEASE HELP IM SO LOST*
Answer:
y = -5x/3 + 18
Step-by-step explanation:
The points can be written as;
(x,f(x))
where f(x) is same as y
So the points we have are;
(6,8) and (9,3)
We start by finding the slope or the line connecting the points
m = y2-y1/x2-x1 = (3-8)/(9-6) = -5/3
So now we have the general form of a linear equation as
y = mx + b
where m is slope and b is y intercept
We already have slope and we want to calculate y-intercept
Simply substitute one of the points
(9,3) in this case
9 for x and 3 for y
we have ;
y = -5x/3 + c
3 = -15 + c
c = 18
So the line equation is;
y = -5x/3 + 18

it costs $4 to enter the fair. each ride costs $2.50. you have $21.50. how many rides can you go on?
(P.S. can you right the equation/ inequality, please)
Hello!
Equation: y = 2.50x + 47 rides.We can write an expression to show this scenario. Write this in the equation format y = mx + b:
m = rate of change, or cost per ride
b = initial cost, or cost to enter the fair
y = 2.50x + 4
Solve for the amount of rides possible with $21.50:
21.50 = 2.50x + 4
Subtract 4 from both sides to isolate x:
17.50 = 2.50x
Divide both sides by 2.50:
17.50/2.50 = 7 rides.

pleaseeee help I only have an hour
Answer:
B. 244.20
Step-by-step explanation:
A was not the right answer
The annual premium for a $110,000 5-year term policy for a 22-year-old female is given by equation A = $ 244.20
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the insurance premium of face value be = $ 1000
Now , the annual premium of 5 year team policy for a female of 22 years is given by B = 2.22
Let the total amount be = $ 110,000
So , the annual premium for a $110,000 5-year term policy for a 22-year-old female A = 2.22 ( total amount / insurance premium of face value )
On simplifying , we get
The annual premium for a $110,000 5-year term policy for a 22-year-old female A = 2.22 ( 110 )
The annual premium for a $110,000 5-year term policy for a 22-year-old female A = $ 244.20
Hence , the annual premium is $ 244.20

a trader earns a profit of $6,000 in 1988 and a profit of $8,000 more than double that amounts in 2003. write and expression that represents this situation and find the profit for 2003
Answer:
p = 8000 + 2(6000)
20000
Step-by-step explanation:
Given that:
Profit in 1988 = 6000
Profit in 2003 = 8000 more Than double the profit made in 1998
Hence profit in 2003 (p) can be expressed as :
p = 8000 + 2(6000)
Hence profit in 2003
p = 8000 + 12000
p = 20,000

If it takes a window washer 90 minutes to clean 11 windows, how long will it take to wash 55 windows at this rate? A. 6.72 hours B. 7.00 hours C. 7.50 hours D. 8.25 hours
Answer:
C. 7.50 hrs
Step-by-step explanation:
Since it takes 90 mins to clean 11 windows, the rate that it takes the washer per window is [tex]\frac{90}{11}[/tex] minutes. At this rate, if he were to clean 55 windows it would take him [tex]\frac{90}{11}(55) = 450[/tex] minutes. This translates into 7.50 hrs.
A television channel shows 3 minutes of adverts in each half hour. How many minutes of adverts does it show from 8am to 11pm
Answer:
90 minutes
Step-by-step explanation:
Given that:
Duration of advert shown per half hour = 3 minutes
3 minutes per 30 minutes = 3 / 30
Number of minutes from 8am to 11pm = 15 hours = (15 * 60) = 900 minutes
3minutes per 30 minutes = x per 900 minutes
3/30 = x / 900
Croas multiply :
30x = 900 * 3
30x = 2700
x = 2700/30
x = 90
Hence, 90 minutes of advert between 8am to 11pm
