interest = $67.50
A= $367.50
I = A - P = $67.50
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 2.5%/100 = 0.025 per year.
Solving our equation:
A = 300(1 + (0.025 × 9)) = 367.5
A = $367.50
The total amount accrued, principal plus interest, from simple interest on a principal of $300.00 at a rate of 2.5% per year for 9 years is $367.50.

Write a recursive formula: 3, 5, 7, 9, 11, 13, 15, 17, 19, 21
Answers
Answer:
[tex]a_1=3[/tex]
[tex]a_n=a_n_-_1+2[/tex]
Step-by-step explanation:
Recursive formula : an = a(n-1) + d
where d = common difference , an = nth term, and n = number of terms
Because we are just writing the recursive formula rather than the explicit formula, the only defined term will be "d" or the common difference.
Here, the common difference is +2. This is evident as you must add 2 to get to 5 and then add 2 to get to 7 etc.
So d = 2
Plugging this into the recursive formula we get an = a(n-1) + 2
Also it's very important to state the first term which is 3 so a1 = 3
420.9536 Find the digits in the ones place, in the tenths place, and in the thousandths place for the following number.
Answers
Answer:
ones: 0
tenths: 9
thousandths: 3
Step-by-step explanation:
Because 0 is at the beginning of the whole "part" of the number, it is a "one" in place value (confusing right??) for example, in the number 54,743, 3 would be the digit in the ones place.
Because 9 is one decimal place across the example number, it is a tenth - because you would need 10 lots of 0.1 in order to make a whole number.
Because 3 is three decimal places across the example number, it is a thousandth - because you would need 1000 lots of 0.001 to make a whole number.
A good way of remembering these decimal place values is by using the number of zeros after 10, 100, 1,000, 10,000, and so on (one zero is a ten-th, two zeros is a hundred-th, etc, etc.)

Answers
Approximately Carlo takes 2 minutes time to sing the song.
Given that, Ariel sings a song in 5.92 minutes. Carlos sings the same song in 7.73 minutes.
What is the rounding off numbers?Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.
Now,
Difference of singing time = 7.73-5.92
= 1.81 minutes
≈ 2 minutes

Mia's error in her thinking was that she interchanged the coordinate of both the x- and y-axis. Also, the point would actually be located at (5, 8).
What is a reflection across the x-axis?In Mathematics, a reflection across the x-axis would maintain the same x-coordinate while the sign of the y-coordinate would change from positive to negative. Therefore, a reflection across the x-axis is given by this transformation rule:
(x, y) → (x, -y)
In Geometry, a reflection across the y-axis of a graph is given by this transformation rule (x, y) → (-x, y).
(x, y) → (-x, y)
(-5, -8) → (5, -8)
Next, we would apply another reflection across the x-axis of a graph as follows:
(x, y) → (x, -y)
(5, -8) → (5, 8)
In conclusion, we can logically deduce that Mia was wrong in her calculations.

Kiefer service company common stock sells for $36. 84 per share and has a market rate of return of 15. 8 percent. The company just paid an annual dividend of $1. 61 per share. What is the dividend growth rate?.
Answers
The dividend growth rate of Kiefer service company is 0.16% . Dividend growth rate can be determined by using the return rate formula.
Dividend growth rate is the annual rate of growth that a particular stock's dividends experience over a specified period of time.
We have given that ,
Common stocks sells or current price = $36.84
Market rate of return (R) = 25.8 %
Annual dividend (D) = $1.61
Rate of return is defined as net gain or loss of। an investments over a specified time period . It is expressed as a percentage of investment initial cost .
Using the formula,
Rate of return = (D1/ current price )+growth rate where,
D1 --> divided of previous year
putting all the values in above formula we get,
15.8 = ( 1.61/36.84) + growth rate
=> growth rate= 15.8 - (1.61/36.84) = 15.756
Hense, the dividend growth rate for Kiefer service company is 0.16%.

Cyclical Unemployment Rate = 7%
What is the Natural Unemployment Rate?
Answers
The Natural Unemployment Rate based on the information is 5%.
What is natural rate of unemployment?The natural rate of unemployment is the lowest unemployment rate when inflation is stable, or the unemployment rate when inflation is not accelerating. The natural rate of unemployment (NAIRU) is the rate of unemployment caused by all factors other than changes in aggregate demand. Potential GDP estimates are based on the long-term natural rate.
The unemployment rate is the proportion of the total labor force that is unemployed but actively looking for work and willing to work. Cyclical unemployment is associated with an industry's business cycle. It is a direct result of a drop in consumer demand, which has resulted in a drop in labor demand. If cyclical unemployment rises, it indicates that the economy is slowing, which is not good.
Cyclical unemployment occurs when labor forces are reduced as a result of business cycles or economic fluctuations. If you are cyclically unemployed, it means that your employer has laid you off to save money during a period of slow business.
In this case, the unemployment will be:

The volumes of the 20% solution, 35% solution, and 80% solution used by the chemist are 18 liters, 12 liters, and 24 liters, respectively.
The chemist has three different acidic solutions. The first solution contains 20% acid, the second contains 35% acid, and the third contains 80% acid. She created 54 liters of a 50% acid mixture, using all 3 solutions. The number of liters of 80% solution used is 2 times the number of liters of 35% solution used.
Let the amounts of 20% solution, 35% solution, and 80% solution used be x, y, and z. We already know that z = 2y. We can write equations as given below.
The sum of the volumes must be equal to the final volume.
x + y + z = 54
x + y + 2y = 54
x = 54 - 3y
Now we will write the equation using the concentrations of the acid.
50%*54 = 20%*x + 35%*y + 80%*z
27 = 0.2(54 - 3y) + 0.35y + 0.8(2y)
2700 = 20(54 - 3y) + 35y + 80(2y)
2700 = 1080 - 60y + 35y + 160y
1620 = 135y

m∠F = (4x - 6)°
m∠G = (5x - 2)°
Now, remember that the sum of the interior angles of a triangle is always equal to 180°.

l = 4w
Now, the formula for the surface area of a cube is;
S = 2lh + 2lw + 2wh
substitute l = 4w in the above equation
S = 2(4w)h+2(4w)w+2wh
S = 8wh+8[tex]w^{2}[/tex]+2wh
S = 10wh + 8[tex]w^{2}[/tex]
formula for the volume of a cube is;

now substitute l=4w in the above equation
V = (4w)wh
V = 4[tex]w^{2}[/tex]h
h = 4[tex]w^{2}[/tex]/V
Put V/2w² for h in the surface area equation to get;
S= 8w² + 10w(V/4w²)
= 8w² + 5V/2w
given that volume V = 25.6 substitute that in the above equation
S = 8w² + 5(25.6)/2w
= 8w² + 128/2w
Since we want to minimize the surface area, let us find the first derivative of S to get;
S' = 16w - 128/2w²
At S' = 0
0 = 16w- 128/2w²

Answers
The length of the swimming pool is 30 feet
The width of the swimming pool is 15 feet
The volume of the swimming pool is 16875 gallons
Given,
Length of the rectangular swimming pool = 2x
Width of the rectangular swimming pool = x
A small concrete walkway surrounds the pool.
The width of the walkway = 2 feet
The area of the walkway = 196 square feet
We have to find the dimensions of the pool;
Here,
Area of rectangle = length x width
Area of walkways = (4x + 8x) + 4 x 4 = 196
12x + 16 = 196
12x = 196 - 16
12x = 180
x = 180/12
x = 15
That is,
Width of the pool is 15 feet
Length of the pool = 2 × x = 15 x 2 = 30 feet
Now,
If the depth of the pool is 6 feet, we have to find the amount of water that the pool can hold if the height of water is 1 foot below the top of the pool.
That is,
Volume of pool = length x width x depth
Here, depth = 6 - 1 = 5 feet

(b) define event a as getting a sum of 5. p(a)
Answers
The probability of each outcome in the sample space = 1/16
The probability of getting a sum of 5 = 1/4
Step-by-step explanation:
We have been given a four-sided die is a pyramid whose four faces are labeled with the numbers 1, 2, 3 and 4
sample space = {(1,1), (1,2), (1,3), (1,4), (2,1),(2,2), (2,3), (2,4),(3,1), (3,2), (3,3), (3,4), (4,1), (4,2), (4,3), (4,4)}
Two fair 4-sided dices are rolled and all sixteen possible outcomes are equally likely.
The possible outcomes can be deduced by making combinations of different faces with a particular face.
given that each of the outcomes in the sample space is equally likely. So the probability of each outcome in the sample space is the same.
now we find the probability of each of the outcomes in the sample space
(a) when two dices are rolled, we have n(s) = 4*4=16
the chances of getting the outcome as (1,1) n(a) = 1
the probability of getting the outcome as (1,1) p(a)= n(a)/n(b)
p(a) = 1/16
so the probability of each outcome in the sample space = 1/16

Answer:
x=9
Step-by-step explanation:
I assume you want me to solve for x.
6x+22=13x-41
Subtract 6x from both sides.
22=7x-41
Add 41 to both sides.
63=7x
Divide both sides by 7.
x=9.
CHECK:
6x+22=54+22=76
13x-41=117-41=76
76=76
So, x=9
