The value of finance charge for this loan is, $1205.5.

A quick and easy method of calculating the interest charge on a loan is called a Simple interest.

Given that;

Solomon is taking out loan ( Principal  P)  = 18,320

Time of loan taken (T) = 2 year

Loan with an APR ( R ) = 3.29%

To find Finance charge for this loan ( I ) we can used the formula,

⇒ I = PRT/100

⇒ I = 18,320 × 3.29 × 2 / 100

Step-by-step explanation:

Number of pieces of candy was set out at a wedding reception = 600

Number of candy left in the jar = 180

Number of candy taken = 600 - 180 = 420

The percentage of candy taken will be:

= 420 / 600 × 100

= 70%

If population grew by 5% from 2010 to 2015 and fell by 3% from 2015 to 2020 , then the population decrease from 2015 to 2020 is 6678    .

Let the population of the city in 2015 be = "p".

To find the population in year "2015" , we first find the growth from 2010 to 2015  ;

⇒ p = 212000×(1 + 0.05) = 212000 × 1.05 = 222600 ;

So, the population in 2015 was 222600 .

Next, we find the population in 2020 by applying the decrease of 3%:

⇒ p = 222600×(1 - 0.03) = 222600×0.97 = 215922

So, the population in 2020 was 215922.

To , find the decrease from 2015 to 2020, we subtract the population in 2020 from the population in 2015 ;

⇒ 215922 - 222600 = -6678

Therefore , the population of the city decreased by 6678 people from 2015 to 2020.

The given question is incomplete , the complete question is

In 2010, the population of a city was 212000. From 2010 to 2015, the population grew by 5%. From 2015 to 2020, it fell by 3%. How much did the population decrease from 2015 to 2020, to the nearest 100 people ?

Answer:

The image of point (1,-4) after a rotation of 180° counter clockwise about the origin is: (-1,4)

Step-by-step explanation:

Rotation means that a point is being moved in clockwise or counterclockwise direction with some angle.

The rotation can be done in 90, 180, 270 degrees.

Given point is:

(1,-4)

When a point (x,y) is rotated 180° counter clockwise its coordinates become (-x,-y) the negative of original point.

So for the given point the coordinates will become (-1,4)

Hence,

The image of point (1,-4) after a rotation of 180° counter clockwise about the origin is: (-1,4)

To accumulate twice the value of $200 deposited at a 4% effective rate, $200 should be left to accumulate at a 7% effective rate for approximately 19 years and 7 months.

To find the time required for $200 to accumulate to twice the value of $200 deposited at a 4% effective rate, we can use the concept of the future value of an investment. Let's denote the time in years as "t".

For the first deposit at a 4% effective rate, the future value can be calculated as:

\(FV = PV * (1 + r)^t,\)

where PV is the present value ($200), r is the interest rate (4% or 0.04), and FV is the future value.

For the second deposit at a 7% effective rate, the future value should be twice the value of the first deposit:

\(2 * (PV * (1 + r)^t) = $200 * (1 + 0.07)^t\).

By solving this equation for "t", we can determine the time required. Rearranging the equation, we get:

\(2 * (1.04)^t = (1.07)^t\).

Taking the logarithm of both sides, we have:

\(log(2) + t * log(1.04) = t * log(1.07)\).

Simplifying the equation, we find:

\(t = log(2) / (log(1.07) - log(1.04))\).

Evaluating this expression, we find that t is approximately 19.58 years or 19 years and 7 months. Therefore, $200 should be left to accumulate at a 7% effective rate for approximately 19 years and 7 months to reach twice the accumulated value of $200 at a 4% effective rate.

Superman begins flying at a constant rate of 100 miles per hour. After one mile he increases his flying rate by 20% and maintains the new rate for the duration of the second mile.

Increasing his rate by 20% at the beginning of each mile. During which mile does his rate first become at least 200 miles per hour?

The rate of Superman when he begins to fly is constant. He starts at 100 mph, and for every mile he flies, he increases his speed by 20%.

In the first mile, his speed would remain at 100 miles per hour.

In the second mile, he will be able to fly at a speed of 120 miles per hour.

Let's make a table for better understanding:

Mile  Rate (in mph) | 1 | 100 | 2 | 120 | 3 | 144 | 4 | 172.8 | 5 | 207.36 |

Using the dual simplex method to find a solution to the linear programming problem formed by adding the constraint 3xi 5x3> 15 to the problem. The final solution is:
xi = 20
x2 = 0
x3 = 15
x4 = 0
x5 = 40

Adding the constraint 3xi + 5x3 > 15 does not affect the optimal solution, as none of the variables involved in the new constraint are in the basis. Therefore, the final solution remains the same.

To use the dual simplex method to find a solution to the linear programming problem formed by adding the constraint 3xi + 5x3 > 15 to the problem in example 2, we need to follow these steps:

1. Rewrite the problem in standard form by adding slack variables:
Maximize 4xi + 3x2 + 5x3
Subject to:
2xi + 3x2 + 4x3 + x4 = 60
3xi + 2x2 + x3 + x5 = 40
xi, x2, x3, x4, x5 >= 0

2. Calculate the initial feasible solution by setting all slack variables to 0:
xi = 0
x2 = 0
x3 = 0
x4 = 60
x5 = 40

3. Calculate the reduced costs of the variables:
c1 = 4 - 2/3x4 - 3/2x5
c2 = 3
c3 = 5 - 2/3x4 - 1/2x5
c4 = -2/3x1 - 1/2x2
c5 = -3/2x1 - 1/2x2

4. Choose the entering variable with the most negative reduced cost. In this case, it is x1.

5. Calculate the minimum ratio test for each constraint to determine the leaving variable:
For the first constraint: x4/2 = 30, x1/2 = 0, so x4 is the leaving variable.
For the second constraint: x5/3 = 40/3, x1/3 = 0, so x5 is the leaving variable.

6. Update the solution by performing the pivot operation:
- Pivot on x1 and x4 in the first constraint: x1 = 20, x4 = 0, x2 = 0, x3 = 15, x5 = 40/3
- Pivot on x1 and x5 in the second constraint: x1 = 0, x4 = 0, x2 = 0, x3 = 15, x5 = 40

7. Repeat steps 3-6 until all reduced costs are non-negative or all minimum ratio tests are negative.

To find the correct equations for the missing boxes, we need more information about the relationships between the different activities in Jake's Gems. However, based on the given context, we can make some assumptions and suggest potential equations:

Mining and Cutting activities produce diamonds, rubies, and other gems. Let's assume that the production of each gem type is represented by a variable: D (diamonds), R (rubies), and G (other gems).

Maintenance supports the Mining and Cutting activities. We can assume that the maintenance effort required for each activity is represented by the variable M (maintenance).Since the question mentions five missing boxes, we can suggest additional equations to represent relationships between these variables, such as:

Mining + Cutting = D + R + G (the sum of all gem types produced equals the total production from Mining and Cutting activities).

Maintenance = M (maintenance effort required).

The relationships between these variables might include equations like D = f(M), R = g(M), G = h(M), where f, g, and h represent some functions or formulas that relate gem production to maintenance effort.
