How long will it take for a sum of money, invested at 5% compounded annually, to double in value?

Answers

Answer 1
Using the compound interest formula, where n=number of years,
2x=x(1+0.05)^n
(1.05)^n=2
=> 
n=log(2)/log(1.05)=14.21 years

Note: This problem can also be solved in the head using the rule of 72.
Since the amount is doubled at an interest rate of 5%, the time needed is 72/5=14 years, approximately.
Answer 2

To determine the time needed for an investment to double at a 5% compounded annual rate, apply the Rule of 72 by dividing 72 by the interest rate, resulting in approximately 14.4 years.

The question pertains to the time it takes for an investment to double in value with compound interest. To calculate this, we can use the Rule of 72. This rule states that you can approximate the number of years it'll take for an investment to double by dividing 72 by the annual interest rate. In this case, with a 5% interest rate, it would be calculated as 72 \/ 5, which equals approximately 14.4 years.

Here's a step-by-step explanation:

Apply the Rule of 72 by dividing 72 by the interest rate: 72 ÷ 5 = 14.4.

Therefore, it will take roughly 14.4 years for the sum of money to double at an annual compounded interest rate of 5%.

This is a quick and efficient way to estimate the power of compound interest and make informed investment decisions.

After 5 months, the number of subscribers to a newspaper was 5,730. After 7 months, the number of subscribers to the newspaper was 6,022. Which equation models the number of newspaper subscribers y after x months? y = –146x – 5,000 y = 146x + 5,000 y = 146x – 5,000 y = –146x + 5,000

Answers

From the information given in the problem we can create a linear model like this: The [tex]x-axis[/tex] will represent the months and the [tex]y-axis[/tex] the subscribers. From the problem we know that after 5 months, the number of subscribers to a newspaper was 5,730, so [tex] x_{1} =7[/tex] and [tex] y_{1} =5730[/tex]. We also know that after 7 months, the number of subscribers to the newspaper was 6,022, so [tex] x_{2} =7[/tex] and [tex] y_{2} =6022[/tex].
Remember that the slope of a line is [tex]m= \frac{y_{2}-y _{1} }{ x_{2} - x_{1} } [/tex]. since we already found those values, lets replace them to find our slope:
[tex]m= \frac{6022-5730}{7-5} [/tex]
[tex]m= \frac{292}{2} [/tex]
[tex]m=146[/tex]

To create our linear model we are going to use the point-slope equation [tex]y- y _{1} =m(x- x_{1} )[/tex]. Notice that we have all the values, so the only thing left is plug them in our equation: 
[tex]y-6022=146(x-5)[/tex]
[tex]y-5730=146x-730[/tex]
[tex]y=146x-730+5730[/tex]
[tex]y=146x+5000[/tex]

We can conclude that the equation which models the number of newspaper subscribers [tex]y[/tex] after [tex]x[/tex] months is [tex]y=146x+5000[/tex]

Todd Gunderson went into a partnership with two of his friends. Manny and Jose, to share a route delivering newspapers. Manny owns 1/4 of the partnership, while Jose has a 1/5 interest. If the partnership's monthly revenue amounts to $765, how much of that is Todd's? Round to the nearest cent.

Answers

To solve you must find how much of the route todd has and multiply that by the total revenue.

Todd + Manny + Jose = 1

X + 1/4 + 1/5 = 1 

Change fractions to decimals for easier solving

x +.25 +.20 = 1

combine like terms

x+ .45 = 1

Subtract .45 from both sides

x=.55

Christian got a haircut yesterday afternoon if the hair stylist charged $18 and christian gave 20% tip how much dod he pay for the haircut

Answers

hey bro just basically add it like this multiply 18 by .20 and then add the answer to 18

Answer:

He paid $ 21.6 for the haircut.

Step-by-step explanation:

Given,

The amount charged by hair stylist = $ 18,

The percentage of tip = 20 %,

So, the amount of the tip = 20 % of 18

= 0.2 × 18

= $ 3.6,

Hence, the total amount paid by him for haircut = The amount charged by hair stylist + Tip

= $ 18 + $ 3.6

= $ 21.6

Hope this helps! Have a blessed day!

Answer:

vertical angles

Step-by-step explanation:

We need to identify ∠1 and ∠4 are which type of pair of angles .

Since we are given the options :

1, correspoding angles: Corresponding Angles

When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles.

2. vertical angles : The angles opposite each other when two lines cross. They are always equal.Vertical" refers to the vertex (where they cross), NOT up/down

3. supplementary angles : Two Angles are Supplementary when they add up to 180 degrees

4. adjacent angles:Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap.

Thus according to definitions ∠1 and ∠4 are vertical angles

A rectangular garden is 6 feet long and 4 feet wide. A second rectangular garden has dimensions that are double the dimensions of the first garden. What is the percent of change in perimeter from the first garden to the second garden? The perimeter increases % from the first garden to the second garden.

Answers

Answer:

  100%

Step-by-step explanation:

When the dimensions double, the perimeter doubles.

The percent change can be found from ...

  percent change = ((new value)/(old value) -1) × 100%

Filling in your values, you have ...

  percent change = ((2×(old perimeter))/(old perimeter) -1) × 100%

  = (2 - 1) × 100%

  = 100%

The perimeter increases by 100% from the first garden to the second.

Consider the quadratic equation x2=4x-5. How many solutions does the equation have

Answers

the quadratic formula is =(-b+-sqrt(b^2-4ac))/2a
as you notice the term under the square root is b^2-4ac if it is postive then the equation clearly will have two real soultions if it is negative then the equation will have two imaginary soultion if it is zero then the the equation will have one soultion
so let us calculate b^2-4ac for our given equation
x^2=4x-5 so let us write it in general form which is ax^2+bx+c=0
subtracting 4x from both sides
x^2-4x=-5
adding 5 to both sides
x^2-4x+5=0
a=1,b=-4,c=5
b^2-4ac=(-4)^2-4(1)(5)=16-20=-4
which means the equation has two imaginary soultions
[tex]\bf x^2=4x-5\implies x^2-4x+5=0 \\\\\\ \begin{array}{lcccll} & 1 x^2& -4 x& +5&=0\\ &\uparrow &\uparrow &\uparrow \\ &a&b&c \end{array} \\\\\\ discriminant\implies b^2-4ac= \begin{cases} 0&\textit{one solution}\\ positive&\textit{two solutions}\\ negative&\textit{no solution} \end{cases}[/tex]

A store charges 7% sales tax. Which expression can be used to find the total cost of an item with a price of p? 0.07p 0.93p 1.07p 7.00p

Answers

If you have an item that costs 10 dollars and a sales tax of 7% you could do it this way


10 * 7/100 = 0.70 dollars.


The total cost is 10.70 dollars. or 10 dollars and 70 cents.

The best way to do the total however is to multiply the cost by 1.07. You will get the number the customer has to pay.

10 * 1.07 = 10.70

So for any price (p) it would be 1.07*p

Answer:

1.07p

Step-by-step explanation:

The tax  equals the price times the tax rate

We know the price p and the tax rate 7%

tax = p*7%

Changing this to decimal form

tax = .07p

The  final price of the item is the sales tax plus the price

final price = tax + price

                   .07p +p

                  1.07p

what is 0.080 as a fraction

Answers

Answer:

To write 0.080 as a fraction you have to write 0.080 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

0.080 = 0.080/1 = 0.8/10 = 8/100

So your final answer is:  0.080 as a fraction equals 8/100

Step-by-step explanation:


The decimal number 0.080 as a fraction is A = 2/25

Given data:

The decimal number is represented as 0.080

Step 1: Count the number of decimal places in the given decimal. So, there are three decimal places.

Step 2: Write the decimal as the numerator of the fraction. The decimal 0.080 becomes the numerator 80.

Step 3: Determine the denominator of the fraction. Since there are three decimal places, the denominator should be 10 raised to the power of the number of decimal places. So, the denominator is 10³ = 1000.

Putting it all together, 0.080 as a fraction is 80/1000.

Dividing both the numerator and denominator by 40:

80 ÷ 40 / 1000 ÷ 40 = 2/25

Hence, 0.080 as a simplified fraction is 2/25.

Andy and alex both decided to order prints of their photos. Andy ordered 40 small 4x6 inch prints and 10 large 8x10 inch prints. He paid a total of $32.50 for his photos. Alex paid 20$ for 20 small 4x6 inch prints and 8 large 8x10 inch prints. How much do the small and large sized prints cost

Answers

Final answer:

To find the cost of small and large prints, we create two equations based on Andy's and Alex's orders and solve for the two variables. The small 4x6 inch prints cost $0.50 each, and the large 8x10 inch prints cost $1.25 each.

Explanation:

To solve how much small and large sized prints cost, we can set up a system of linear equations based on the information given:

Andy's order: 40 small prints and 10 large prints for $32.50Alex's order: 20 small prints and 8 large prints for $20.00

Let s represent the cost of a small 4x6 inch print, and let l represent the cost of a large 8x10 inch print. We can then form the equations:

40s + 10l = 32.5020s + 8l = 20.00

By dividing the first equation by 2, we get:

20s + 5l = 16.25

Subtracting the second equation from this result gives:

(20s + 5l) - (20s + 8l) = (16.25 - 20)-3l = -3.75l = 1.25

With the cost of a large print found, we can plug this back into the second equation to find the cost of a small print:

20s + 8(1.25) = 2020s + 10 = 2020s = 10s = 0.50

Therefore, the cost of a small 4x6 inch print is $0.50 and a large 8x10 inch print is $1.25.

Simplify 10/16 to lowest terms and find an equivalent fraction that has a denominator of 32?

Answers

Answer:

The lowest fraction for [tex]\frac{10}{16}[/tex] is [tex]\frac{5}{8}[/tex] and a equivalent fraction with denominator of 32 is [tex]\frac{20}{32}[/tex].

Step-by-step explanation:

First, to have the fraction to the lowest terms we will have to divide the numerator and denominator by 2, this is:

[tex]\frac{10/2}{16/2}=\frac{5}{8}[/tex]

As can be seen the expression couldn't be simplified more because there is no a common number that could divide the numerator and denominator.

Second, to have an equivalent fraction with 32 in the denominator we will have to multiply the denominator by 2 and of course the numerator, this is:

[tex]\frac{10*2}{16*2}=\frac{20}{32}[/tex]

The lowest fraction for [tex]\frac{10}{16}[/tex] is [tex]\frac{5}{8}[/tex] and a equivalent fraction with denominator of 32 is [tex]\frac{20}{32}[/tex].

Final answer:

To simplify 10/16 to lowest term, it becomes 5/8. An equivalent fraction of 5/8 with 32 as the denominator is 20/32.

Explanation:

To simplify 10/16 to its lowest term, we have to find the greatest common divisor of 10 and 16, which is 2. Hence, when we divide both the numerator and the denominator by 2, we get 10/2 = 5 and 16/2 = 8. So, the fraction 10/16 simplified to its lowest term is 5/8.

Now, to find an equivalent fraction with 32 as the denominator, we need to multiply both the numerator and the denominator of 5/8 by the same number so as not to change the value of the fraction. Here, we multiply by 4 (since, 8*4 = 32) to get 5*4 = 20 on the numerator. Therefore, an equivalent fraction of 5/8 with 32 as the denominator is 20/32.

b. Translate vertex X to vertex C; rotate ΔXYZ to align the sides and angles.
c. Reflect ΔABC across side AB; translate vertex C to vertex X.
d. Translate vertex X to vertex A; rotate ΔXYZ to align the sides and angles.

Answers

Solution: The correct option is d, i.e., Translate vertex X to vertex A; rotate ΔXYZ to align the sides and angles.

Explanation:

we know that the sum of angles of a triangle is always [tex]180^{\circ}[/tex]. In ΔXYZ,

[tex]\angle X +\angle Y +\angle Z=180^{\circ}[/tex]

[tex]35^{\circ} +\angle Y +47^{\circ}=180^{\circ}[/tex]

[tex]\angle Y +82^{\circ}=180^{\circ}[/tex]

In both triangles it is noticed that the sides AC and XZ are equal. In given triangles [tex]\angle A =\angle X=35^{\circ}[/tex] and [tex]\angle B =\angle Y=98^{\circ}[/tex].

By AAS rule of congruence ΔABC and ΔXYZ are congruent triangles, therefore we can transform ΔABC to ΔXYZ. For the transformation of ΔABC to ΔXYZ translate the vertex having same angle and rotate the triangle to align the sides and angles.

Since vertex X and vertex A have same angle, therefore we translate vertex X to vertex A and rotate ΔXYZ to align the sides and angles.
