Bonnie deposited $1000 in an investment account on the first of January in 2001. The account pays 7.2% interest compounded annually. How much is the investment worth at the end of 2005? please help, having a mental break down over my math homework <3
Answer:
About $1415.71
Step-by-step explanation:
We can use the formula for compound interest, given by:
[tex]\displaystyle A=P(1+\frac{r}{n})^{nt}[/tex]
Where P is the initial amount, r is the rate, n is the number of times compounded annually, and t is the time in years.
Our initial amount is the $1000 Bonnie deposited. So, P = 1000.
Our rate is the interest, which is 7.2% of 0.072. So, r = 0.072.
Since it is compounded annually, our n = 1. So, we have:
[tex]A=1000(1+0.072)^t[/tex]
We want the amount after 5 years. So, t = 5. Substitute and evaluate:
[tex]A=1000(1.072)^5\approx\$1415.71[/tex]
The investment will be worth about $1415.71 after 5 years.

Answer:
167.143
Step-by-step explanation:
2:6:7
7 for the perimeter
195/7= 27.875
27.875 * 6 =167.143
Answer:
91 meters
Step-by-step explanation:
First find the denominator in the ratio by adding every value up.
[tex]2 + 6 + 7 = 15[/tex]
Now, divide 195 by 15.
[tex]195 \div 15 = 13[/tex]
The longest must be the one with the 7 in the ratio, so we multiply 7 by 13.
[tex]7 \times 13 = 91[/tex]
The longest side is 91 meters long.

A small business makes bottles of lemonade. Today, they have 528 ounces of lemonade to bottle. Each bottle holds 24 ounces of lemonade. They sell each bottle for 2 dollars. How many dollars will the business recive?
Answer:
$44
Step-by-step explanation:
From the above question:
24oz of Lemonade = 1 bottle
528 oz of Lemonade = m
Cross Multiply
24 × m = 528
m = 528/24
m = 22 bottles
We are told that: they sell each bottle for $2
Hence:
1 bottle = $2
22 bottles = z
Cross Multiply
z = 22 × $2
z = $44
Hence, the amount of dollars that the business will receive = $44
Write the exponential equation for this scenario. Mike buys a car for $45,000.00. The cars value depreciates (loses value) at a rate of 18% per year.
Answer:
[tex]A=45000(0.82)^t[/tex]
Step-by-step explanation:
Given data
P= 45,000
rate= 18%
Recall the expression for the compound interest
[tex]A=P(1+r)^t[/tex]
Since we are talking of depreciation
[tex]A=P(1-r)^t[/tex]
Substitute
[tex]A=45000(1-0.18)^t\\\\A=45000(0.82)^t[/tex]
Hence the exponential function is
[tex]A=45000(0.82)^t[/tex]

Answer:
El sistema de ecuaciones para calcular la cantidad de niños y adultos que acudieron a la función es:
x+y=270
175x+200y=88,250
Step-by-step explanation:
La información proporcionada indica que a la función entran 470 asistentes entre adultos y niños y con esta información puedes decir que la suma de niños y adultos que entran a la función es igual a 470:
x+y=270, donde
x es el número de niños
y es el número de adultos
Además, se indica que se recaudaron $88,250 y tienes los precios de cada entrada por lo que puedes expresar que la suma de los resultados de multiplicar cada precio por la cantidad de personas que entraron por ese precio es igual a $88,250:
175x+200y=88,250
De acuerdo a esto, la respuesta es que el sistema de ecuaciones para calcular la cantidad de niños y adultos que acudieron a la función es:
x+y=270
175x+200y=88,250
Sameer's father is two years more than three times Sameer's age. Write Sameer father's age if Sameer is x years old at present
Answer:
3x+2
Step-by-step explanation:
Let Sameer age be x years old at present
Three times Sameer's age = 3 * x = 3x
Two years more than three times Sameer's age = 3x + 2
If Sameer's father is two years more than three times Sameer's age, the the age of Sameer's father at present will be (3x+2) years
So here this question is of concept linear equations. As in linear equations we assumes the unknown number as an variable. Here also we would be doing same.!!
Here we have been provided with a condition that the Sameer's father is two years more than three times Sameer's age.
But we won't be assuming the age of Sameer as any other variable other than x. (Because it's given in the question)
★ Therefore according to the question,
[tex]\implies \: \underline{\boxed{ \sf{Age \: of \: Sameer's \: father \: = \: 3 (Age \: of \: Sameer) \: + \: 2}}} \: \red\bigstar[/tex]
Substituting the age of Sameer as x.
[tex] \longrightarrow \: \sf{Age \: of \: Sameer's \: father \: = \: 3 (x) \: + \: 2} \: \\ \\ \longrightarrow \: \sf{Age \: of \: Sameer's \: father \: = \: 3 \times (x) \: + \: 2} \\ \\ \longrightarrow \: \red{\sf{Age \: of \: Sameer's \: father \: = \: 3x \: + \: 2}}[/tex]
Henceforth,
Age of Sameer's father is (3x + 2)Please help me

Your table is poorly presented
Given
x y
[tex]\begin{array}{cc} {3} & {1.47} \ \\ {5} & {2.45} \ \\ {9} & {4.41} \ \ \end{array}[/tex]
First, we calculate the constant of proportionality (k)
[tex]k = \frac{y}{x}[/tex]
For (3,1.47)
[tex]k = \frac{1.47}{3}[/tex]
[tex]k = 0.49[/tex]
For (5,2.45)
[tex]k = \frac{2.45}{5}[/tex]
[tex]k = 0.49[/tex]
For (9,4.41)
[tex]k = \frac{4.41}{9}[/tex]
[tex]k = 0.49[/tex]
From the above calculations, the constant of proportionality is 0.49.
So, the usable rows must also have 0.49 as their constant of proportionality
Choice A
[tex](x,y) = (2,0.98)[/tex]
[tex]k = \frac{0.98}{2}[/tex]
[tex]k = 0.49[/tex] --- This is usable
Choice B
[tex](x,y) = (7,4.45)[/tex]
[tex]k = \frac{4.45}{7}[/tex]
[tex]k = 0.64[/tex] --- This is not usable
Choice C
[tex](x,y) = (6,2.94)[/tex]
[tex]k = \frac{2.94}{6}[/tex]
[tex]k = 0.49[/tex] --- This is usable
Choice D
[tex](x,y) = (1,0.54)[/tex]
[tex]k = \frac{0.54}{1}[/tex]
[tex]k = 0.54[/tex] ---- This is not usable
Choice E
[tex](x,y) = (8,3.92)[/tex]
[tex]k = \frac{3.92}{8}[/tex]
[tex]k = 0.49[/tex] --- This is usable

W and B share the cost of purchasing a TV. B pays 4/10 of the bill and W pays $32 more than B. How much did each pay?
Answer:
W paid $96
B paid $64
Step-by-step explanation:
Let the total amount paid be $x
From the question, we are told that B pays 4/10
That means what W paid will be;
1-4/10 = 6/10
Thus, we have that;
6/10 * x - 4/10 * x = 32
6x/10 -4x/10 = 32
2x/10 = 32
2x = (32 * 10)
2x = 320
x = 320/2
x = $160
6/10 = 6/10 * 160 = $96
4/10 = 4/10 * 160 = $64

In the world of right triangles why does a (squared) + b(squared) = c(squared)? thanks konrad streuli
Answer:
Pythagoras Theorem
Step-by-step explanation:
Like you rightly stated, in a right angled triangle. The phenomenon you mentioned is what us called Pythagoras theorem which proved to us that the square of the length of the hypotenuse of a right angled triangle, is equal to the square of the length of the opposite side to the angle in question, and also to the square of the length of the side adjacent to the same angle in question.
Essentially,
a² + b² = c², where c is the hypotenuse and a & b is the length of the two other sides

Step-by-step explanation:
The rectangular floor of a classroom is 30 feet in length and 38 feet in width. A scale drawing of the floor has a length of 15 inches. What is the perimeter, in inches, of the floor in the scale drawing?
Length of the rectangular floor of a classroom = 30 feet
Width of the rectangular floor of a classroom = 38 feet
Length of the floor in a scale drawing = 15 inches
Which means, 1 inch is equal to :
[tex] = \tt\frac{30}{15} [/tex]
[tex] = \tt2 \: feet[/tex]
Thus, 1 inch in the drawing is equivalent to 2 feet of the floor.
Then, width of floor in the scale drawing :
[tex] = \tt\frac{38}{2} [/tex]
[tex] = \tt19 \: inches[/tex]
Thus, the width of the floor in the scale drawing = 19 inches
Perimeter of the floor in the scale drawing :
[tex]= \tt2(length + breadth)[/tex]
[tex] =\tt 2(15 + 19)[/tex]
[tex] =\tt 2(34)[/tex]
[tex] =\color{plum}\tt68 \: inches[/tex]
Thus, perimeter = 68 inches
Therefore, the perimeter of the rectangular floor in the scale drawing = 68 inches
Answer:
P = 2L + 2W
W = 5
P = 2L + 2(5) = 16
2L + 10 = 16
2L = 6
L = 3 ft
Step-by-step explanation:
So we know that the perimeter of a rectangle= 2 (length + width).
We set up the equation so it's 16= 2 (length+ 5)
Divide both sides by 2, so 8 = length + 5.
Subtract 5 from both sides and you get length = 3
