Answer:
Amelia needs to invest $989.57.
Step-by-step explanation:
The compound interest formula is given by:
\(A(t) = P(1 + \frac{r}{n})^{nt}\)
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Amelia is going to invest in an account paying an interest rate of 2.3% compounded quarterly.
This means that \(r = 0.023, n = 4\).
How much would Amelia need to invest, to the nearest hundred dollars, for the value of the account to reach $1,530 in 19 years?
We have to find P for which \(A(t) = 1530\) when \(t = 19\). So
\(A(t) = P(1 + \frac{r}{n})^{nt}\)
\(1530 = P(1 + \frac{0.023}{4})^{4*19}\)
\(P = \frac{1530}{(1 + \frac{0.023}{4})^{4*19}}\)
\(P = 989.57\)
Amelia needs to invest $989.57.
Ten boxes of paper weigh 260 pounds. Mrs. Thomas
ordered 24 boxes of paper for the science department.
How many pounds do 24 boxes of paper weigh?
Answer:
624 pounds
Step-by-step explanation:
If 10 boxes of paper weigh 260 pounds, one box of paper is equal to 26 pounds because 260 divided by 10 is equal to 26. If one box equals 26 pounds, 24 boxes times 26 pounds each is equal to 624 pounds.

What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
Given that \(a_0=10\) and \(a_n+1=-5a_n\)
This is a recursive formula. So we can simply substitute in each value. For instance, a₂
Use the recursive definition repeatedly.
a2 = -5(6) +4 = -26
a3 = -5(-26) +4 = 134
a4 = -5(134) +4 = -666
Therefore, the value of a4 is -666

James invested some money at 6% interest. James also invested $211 more than 4 times that amount at 11%. How much is invested at each rate if James receives $1522.21 in interest after one year?
$1,488.45 is invested at 6% and $6,164.8. is invested at 11%.
What is Interest?The fee you pay to borrow money or the fee you charge to lend money is called interest. The most common way to represent interest is as a yearly percentage of the loan amount. The interest rate on the loan is known as this percentage.
Given:
James invested some money at 6% interest.
James also invested $211 more than 4 times that amount at 11%.
Let x represent the amount invested at 6%.
Then (4x+211) is the amount invested at 11%.
So, The total interest earned in 1 year is
(11%)(x) +(16%)(4x+211) = 1561.50
0.11x + 0.16(4x+ 211)= 1522.21
0.11x + 0.64x + 33.76 = 1522. 21
0.75 x = 1,488.45
x= 1,488.45
and, 4x +211 = 4(1488.45) + 211 = $6,164.8.

Los 1600 euros de alquiler de un terreno se reparten entre tres ganaderos que llevan alli a pastar sus ovejas. Como no tienen el mismo número de ovejas, deciden pagar proporcionalmente al número de ovejas de cada uno. Si el primero tiene 120 Ovejas,el segundo 72 y el tercero 68. ¿ Cuánto paga cada uno?

What is proportion?Proportion refers to the equality of two ratios. In other words, when two ratios are set equal to each other, they form a proportion. A proportion is typically written in the form of two fractions separated by an equals sign, such as a/b = c/d. Proportions are commonly used in mathematics to solve problems involving ratios and proportions, such as finding missing values or scaling up or down a given quantity.
Here,
To find out how much each farmer pays, we need to determine the proportion of the total rent that each farmer owes based on the number of sheep they have. First, we need to find the total number of sheep:
120 + 72 + 68 = 260
The first farmer has 120 sheep, which is 46.15% of the total number of sheep (120/260). Therefore, the first farmer owes 46.15% of the rent:
0.4615 x 1600 = 738.40 euros
Similarly, the second farmer has 72 sheep, which is 27.69% of the total number of sheep (72/260). Therefore, the second farmer owes 27.69% of the rent:
0.2769 x 1600 = 443.04 euros
The third farmer has 68 sheep, which is 26.15% of the total number of sheep (68/260). Therefore, the third farmer owes 26.15% of the rent:
0.2615 x 1600 = 418.56 euros

Answer:

Step-by-step explanation:
If f(x) and \(f^{-1}\) are inverse functions, then
f(\(f^{-1}\))(x) = x
Thus substitute x = \(f^{-1}\) (x) into f(x)
f(\(\frac{x+6}{5}\) )
= 5 (\(\frac{x+6}{5}\) ) - 6
= x + 6 - 6
= x
Thus f(x) and \(f^{-1}\) (x) are inverse functions

if a pound of almonds cost eight dollars how many ounces can be bought for $3.80
Proportions
A pound of almonds is said to cost 8 dollars.
But one pound is equivalent to 16 ounces, therefore:
16 ounces cost 8 dollars
Dividing by 8 we get that
2 ounces of almonds cost 1 dollar
Thus, for $3.80 we can buy 2*3.80 = 7.60 ounces of almonds

Use Demoivres Theorem to find (-square root 3 +i)^6
Answer:
\(z=(-\sqrt{3}+i)^6\) = -64
Step-by-step explanation:
You have the following complex number:
\(z=(-\sqrt{3}+i)^6\) (1)
The Demoivres theorem stables the following:
\(z^n=r^n(cos(n\theta)+i sin(n\theta))\) (2)
In this case you have n=6
In order to use the theorem you first find r and θ, as follow:
\(r=\sqrt{3+1}=2\\\\\theta=tan^{-1}(\frac{1}{\sqrt{3}})=30\°\)
Next, you replace these values into the equation (2) with n=6:
\(z^6=(2)^6[cos(6*30\°)+isin(6*30\°)]\\\\z^6=64[-1+i0]=-64\)

Susan is running a 5k race. The graph of distance vs. time is shown.
What interval is she running the fastest?
The interval of the graph at which Susan is running fastest is from point A ( 0 , 0 ) to B ( 10 , 3 )
Given data ,
Susan is running a 5k race. The graph of distance vs. time is shown
So , the slope of the first line is m₁
And , the slope of the second line is m₂
where the points are A ( 0 , 0 ) , B ( 10 , 3 ) , C ( 20 , 4 )
Now , slope of AB is
m₁ = ( 3/10 ) = 0.3
And , m₁ = 0.3 kilometers per minute
And , slope of BC is
m₂ = ( 4 - 3 ) / ( 20 - 10 )
m₂ = 1/10
m₂ = 0.1 kilometers per minute
Therefore , the interval is fastest at second line from B ( 10 , 3 ) , C ( 20 , 4 )
Hence , Susan is running fastest is from point A ( 0 , 0 ) to B ( 10 , 3 )

Three specimens of Alloys A, B, C containing copper and zinc are melted together to create an ingot containing 20% copper and 40% zinc. What are the percentages X and Y of copper and zinc in the alloy A?
Answer:
X=10%
Y=30%
Step-by-step explanation:
The required percentages X and Y of copper and zinc in alloy A are given as 10% and 13.34%.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Percentage of copper in A = 1/2 [percentage of copper in ingot]
= 1/2 × 20% = 10%
Percentage of zinc in A = 1/3 [percentage of zincin ingot]
= 1/3 × 40% = 13.34%
Thus, the required percentages X and Y of copper and zinc in alloy A are given as 10% and 13.34%.

How to determine the number of intersection pointsGiven that
Line AB and circle P lie on the same plane.
And, we have
AP = 6 mm
BP = 8 mm
The intersection points can be 0, 1, or 2.
Since the radius of circle P is 6mm, any intersection point must also be 6mm away from P.
Next, we have the following test cases
If line AB intersects circle P at one point, then that point must be on the circle centered at P and have a radius of 6mm. If line AB intersects circle P at two points, then both points must be on the same circle centered at P with a radius of 6mm.Hence, the answer is (A) 1 point or 2 points.
