The difference between the total and the initial contribution, which is: Interest [tex]= $5,409.09 - $5,000, I[/tex] nterest $409.09, is the amount of interest earned. Lupita will have accrued interest of $409.09, rounded to the closest penny, after 48 months.

We can use the compound interest calculation to determine how much money Lupita will receive after 48 months:

Where: [tex]A = P(1 + r/n)(nt)[/tex] A represents the whole sum after t years.

P represents the primary sum.

The yearly interest rate is r.

Given that interest is compounded yearly, [tex]P = $5,000, r = 0.02, n = 1,[/tex]and[tex]t = 48/12 = 4[/tex] (since the time is given in months, we need to convert to years by dividing by 12).

Hence, the equation is: [tex]A = $5,000(1 + 0.02/1)^(1*4)[/tex]

[tex]A = $5,000(1.02)^4\sA ≈ $5,409.09[/tex]

The amount that differs between the total and the original deposit that represents interest earned is: Interest equals [tex]$5,000 - $5,409.09$409.09[/tex] in interest

Lupita will have accrued interest of $409.09, rounded to the closest penny, after 48 months.

Answer: Let's call the first term of the arithmetic progression "a" and the common difference "d". Then we can use the following formulas to find the second, fifth, and seventh terms:

- The second term is a + d.

- The fifth term is a + 4d.

- The seventh term is a + 6d.

We are given that the sum of the second and seventh terms is 25:

(a + d) + (a + 6d) = 25

Simplifying this equation, we get:

2a + 7d = 25 ...(1)

We are also given that the fifth term is 15:

a + 4d = 15 ...(2)

Now we can solve for the common difference "d" by using equations (1) and (2) to form a system of two equations in two variables. One way to do this is to solve equation (2) for "a" in terms of "d", and then substitute that expression for "a" into equation (1):

a = 15 - 4d ...(3)

Substituting equation (3) into equation (1), we get:

2(15 - 4d) + 7d = 25

Simplifying this equation, we get:

30 - 8d + 7d = 25

Solving for "d", we get:

d = -5

Therefore, the common difference is -5.

I believe this what you're asking:

To estimate the sum of 3.456 and 8.79, we can round each number to one decimal place, and then add them:

3.456 ≈ 3.5

8.79 ≈ 8.8

So, 3.456 + 8.79 ≈ 3.5 + 8.8 = 12.3

Therefore, we can estimate that the sum of 3.456 and 8.79 is approximately 12.3.

In equation form, this can be written as:

3.456 + 8.79 ≈ 3.5 + 8.8 = 12.3

Therefore , the solution of the given problem of probability comes out to be  the likelihood that they have four girls is 1/15.

The assessment of the probability that a claim is true or that a particular event will happen is the main objective of the constructions inside style known as criteria. Chance can be symbolised by any number between zero and 1, for which 1 typically denotes certainty range and 0 typically denotes possibility. A probability diagram illustrates the likelihood that a particular occurrence will take place. Decimal digits 0, 1, rationals with just 0% and roughly 100%.

Here,

Given that the family has at least one girl, we can use Bayes' theorem to determine the likelihood that they have four girls:

=> P(4 girls | at least one girl) = P(4 girls)

=> Times P(at least one girl | 4 girls) / P. (at least one girl)

Additionally, we are aware that the probability of having at least one female is

=> P(at least one girl = 1 - P(no girls) = 1 - (1/2)4 = 15/16.

The likelihood of not having any females is equal to the likelihood of having four boys,

which is

=>  (1/2)4 = 1/16.

Given that all four of the children are female, the likelihood of producing girls is one.

Combining everything, we have:

=> P(4 females | a girl)

=> 1 * (1/16) / (15/16) = 1/15

Given that the household has at least one girl, the likelihood that they have four girls is 1/15.

According to the given information, the coordinates of C′ are (-7, 3.5).

What is the scaling of a triangle?

Scaling is a type of transformation in which the size of an object, in this case, a triangle, is changed while its shape and orientation are maintained. In other words, scaling involves multiplying the coordinates of the vertices of the triangle by a factor called the scale factor.

To dilate a triangle using a scale factor of 3.5, we need to multiply the distance between each vertex and the center of dilation by 3.5. The center of dilation can be any point, but for simplicity, we can choose the origin (0,0).

So, the coordinates of the new vertex C′ can be found by multiplying the distance between the old vertex C(-2,1) and the origin (0,0) by 3.5, and then adding this to the coordinates of the origin.

The distance between C and the origin is [tex]\sqrt{(-2-0)^2+(1-0)^2}[/tex] = [tex]\sqrt{5}[/tex] so the distance between C′ and the origin is [tex]3.5*\sqrt{5}[/tex].

Therefore, the coordinates of C′ are (-23.5, 13.5) = (-7, 3.5).

So, the answer is C′(-7, 3.5).

Answer:

Therefore, 147 is 12% of 1225.

Solving a system of equations we can see that the correct option is A.

Here we can define the variables:

g = snacks in one pack of granola bars.

f = snacks in one pack of fruit rolls.

And we can write a system of equations like:

10g + 6f = 152

7g + 12f = 200

If we take the difference between two times the first equation and the second, we will get:

2*(10g + 6f) - (7g + 12f) = 2*152 - 200

13g = 104

g = 104/13 = 8

There are 8 snacks in a pack of granola, and with that value we can find f.

10g + 6f = 152

6f = 152 -10g

f = (152 - 10*8)/6 = 12

We conclude that the correct option is A.

As I posted ....looks to be 147°

The set o rates that Frank could use to finish the events within 7.5 hours is (0.75 km/h, 25 km/h, 12.5 km/h).

To determine the rates at which Frank must complete each event to finish the triathlon within 7.5 hours, we can use the formula:

time = distance / rate

where;

Let x be the rate at which Frank completes the swim,

y be the rate at which he completes the bike ride, and

z be the rate at which he completes the run.

Then, we have the following three equations:

2.25 / x + 65 / y + 20 / z = 7.5

x > 0, y > 0, z > 0

We want to find the set of rates (x, y, z) that satisfy these equations and inequalities.

Here is one possible set of rates that would allow Frank to complete the triathlon within 7.5 hours:

x = 0.5 km/hour

y = 20 km/hour

z = 10 km/hour

Using these rates, we can calculate the time it would take Frank to complete each event:

Swim: 2.25 km / 0.5 km/hour = 4.5 hours

Bike ride: 65 km / 20 km/hour = 3.25 hours

Run: 20 km / 10 km/hour = 2 hours

The total time would be:

4.5 + 3.25 + 2 = 9.75 hours

This is greater than 7.5 hours, so Frank would need to increase his rates to finish within the time limit.

Here are some possible sets of rates that would allow him to do so:

x = 0.75 km/hour, y = 25 km/hour, z = 12.5 km/hour

x = 1 km/hour, y = 30 km/hour, z = 15 km/hour

x = 1.25 km/hour, y = 35 km/hour, z = 17.5 km/hour

Using any of these sets of rates, Frank would be able to complete the triathlon within 7.5 hours.

b = 10

c = 26

======================================================

Explanation:

We're given a list of possible b values and they are:

4, 5, 8, 10, 12, 24

Let's make a table to show what each value of 'a' would be based on those b values above.

[tex]\begin{array}{|c|c|} \cline{1-2}b & a\\\cline{1-2}4 & 12\\\cline{1-2}5 & 14\\\cline{1-2}8 & 20\\\cline{1-2}10 & 24\\\cline{1-2}12 & 28\\\cline{1-2}24 & 52\\\cline{1-2}\end{array}[/tex]

Example calculation: If b = 4, then a = 2b+4 = 2*4+4 = 12 (first row)

I recommend using spreadsheet software to quickly compute these values. Also, a spreadsheet is useful to organize the data into a table.

Next we'll add a third column c.

This column will be computed using the formula [tex]c = \sqrt{a^2+b^2}[/tex] which is based from the pythagorean theorem [tex]a^2+b^2 = c^2[/tex]

So,

[tex]\begin{array}{|c|c|c|} \cline{1-3} & & \\b & a & c = \sqrt{a^2+b^2}\\\cline{1-3}4 & 12 & 12.6491\\\cline{1-3}5 & 14 & 14.8661\\\cline{1-3}8 & 20 & 21.5407\\\cline{1-3}10 & 24 & 26\\\cline{1-3}12 & 28 & 30.4631\\\cline{1-3}24 & 52 & 57.2713\\\cline{1-3}\end{array}[/tex]

Each decimal value mentioned is approximate. The only time c is an integer is when a = 24 and b = 10.

So that's how I got a = 24, b = 10, c = 26 as the final answer.

A math equation is a technique that links two assertions and denotes equivalence using the equals sign (=). In algebra, an equation is a mathematical statement that proves the equality of two mathematical expressions. For example, in the equation 3x + 5 = 14, the equal sign separates the numbers 3x + 5 and 14. A mathematical formula may be used to understand the link between the two phrases written on either side of a letter. The logo and the programmed are usually interchangeable. As an example, 2x - 4 equals 2.  

The area of a triangle in hyperbolic geometry is determined by the formula:

Area = K ∙ (α + β + γ - π)

where K is a constant that depends on the curvature of the space and,, and are the triangle's angles.
