A loan for $3,400 at 16% should be paid first as it has the highest interest rate.

A loan is a financial agreement in which one party (the lender) agrees to give money, property, or other assets to another party (the borrower) in exchange for the promise of repayment with interest or other charges. Loans are typically used by individuals, businesses, or governments to finance specific projects, make purchases, or cover expenses.

Assuming that all other factors such as minimum payments and penalties are the same, the loan that you should try to pay off first is the one with the highest interest rate, as it will be accruing interest at a faster rate than the others.

Based on this reasoning, the loan that you should try to pay off first is option A, which has a higher interest rate of 16%.

To divide 240g in the ratio 5:3:4, we need to find out the total number of parts of the ratio:

5 + 3 + 4 = 12

Now, we can find the value of one part of the ratio by dividing the total quantity by the total number of parts:

240g ÷ 12 = 20g

So, one part of the ratio is equal to 20g.

To find the quantities of each part of the ratio, we multiply the value of one part by the respective ratio number:

5 parts x 20g = 100g (for the first part)

3 parts x 20g = 60g (for the second part)

4 parts x 20g = 80g (for the third part)

Therefore, the quantities of 240g divided in the ratio 5:3:4 are 100g, 60g, and 80g respectively.

Step-by-step explanation:

The height of the cable above the bridge is given by the function:

h(x) = 0.25x^2 - 0.8x + 30

To find the minimum height of the cable above the bridge, we need to find the vertex of the parabola, which is the lowest point.

The x-coordinate of the vertex is given by:

x = -b / 2a

where a = 0.25 and b = -0.8. Substituting these values, we get:

x = -(-0.8) / 2(0.25) = 1.6

So the vertex is at x = 1.6.

To find the height of the cable at the vertex, we substitute x = 1.6 into the equation for h(x):

h(1.6) = 0.25(1.6)^2 - 0.8(1.6) + 30 = 29.48

Therefore, the minimum height of the cable above the bridge is approximately 29.48 feet (rounded to two decimal places).

Mathematicians examine numbers with their modifications, equations and associated structures, forms and their locations, and feasible positions for these things. The term "function" indicates the connection between a collection of inputs, each of which has a corresponding output. A function is a connection of inputs and outputs where each supply leads to a specific, identifiable outcome. Each function is assigned a domain, a codomain, or a scope. The letter f is widely used to denote functions (x). The symbol for entry is an x. The four primary types of accessible capabilities are on functions, yet another skills, so multiple capabilities, in capabilities, and on operations.

Let's start by writing down the phrases from the problem:

• The teacher's age is six years older than the student's age: T = 2x + 6, where T is the age of the instructor.

• The principal's age is ten years older than the student's age: P = 3x + 10, where P is the age of the principal.

To determine how many years the principal is older than the instructor, subtract the teacher's age from the principal's age:

P - T = (3x + 10) - (2x + 6)

When we simplify the equation, we get:

P - T = x + 4

As a result, x + 4 denotes the number of years the principal is older than the instructor, where x is the student's age in years.

Answer:

Step-by-step explanation:

Yes, that is correct. The measure of the exterior angle of a triangle is equal to the sum of the two remote interior angles. In other words, if you extend one side of a triangle to form an exterior angle, then the measure of that exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to the exterior angle. This property is known as the Exterior Angle Theorem.

Mathematically, we can express this as:

Exterior angle = Sum of remote interior angles

Or, in symbols:

∠ABC = ∠A + ∠C

where ∠ABC is the exterior angle formed by extending side BC of triangle ABC, and ∠A and ∠C are the two remote interior angles.

Here are two more examples that illustrate the Exterior Angle Theorem:

Example 1:

Consider a triangle ABC with angles A, B, and C as shown below. If we extend side AC to form an exterior angle, then we can label the exterior angle as ∠DCE. The remote interior angles are ∠B and ∠A.

In this case, we have the side οppοsite the 60° angle (which is the lοnger leg) equal tο x√3 and the side οppοsite the 30° angle (which is the shοrter leg) equal tο x.

Sο we can set up the fοllοwing equatiοn:

x√3 = 2x sin 60°

Simplifying the right side:

sin 60° = √3/2

2x sin 60° = 2x(√3/2) = x√3

x√3 = x√3

This means that option A, "4 < d < 26," is the correct answer.

The triangle inequality can be used to calculate various distances between Sherry and Amy. The lengths of any two sides of a triangle must add up to more than the length of the third side in order for the triangle inequality to hold.

If we assume that d is the separation between Amy and Sherry in this instance, we can then create a triangle with sides that are 11, 15, and d in length. The inequality of the triangle indicates that:

11 + 15 > d

or

d < 26

Answer: To solve the system of equations using the matrix method, we first need to set up the corresponding coefficient matrix and augmented matrix:

Coefficient matrix:

[1  4]

[2 -3]

Augmented matrix:

[1  4 | 9]

[2 -3 | 7]

To solve the system using matrix method, we perform row operations on the augmented matrix to get it into row echelon form, and then back substitute to obtain the solutions.

Performing row operations:

Multiply the first row by 2 and subtract the result from the second row:

[1  4 | 9]

[0 -11| -11]

Divide the second row by -11:

[1  4 | 9]

[0  1 | 1]

Subtract 4 times the second row from the first row:

[1  0 | 5]

[0  1 | 1]

The row echelon form of the augmented matrix is:

[1  0 | 5]

[0  1 | 1]

Therefore, the solution is x = 5 and y = 1.

So the solution of the system of equations is x = 5 and y = 1.

Answer:

(x - 5)^2 + (y - 5)^2 = 25

Step-by-step explanation:

If a circle has no x-intercepts and no y-intercepts, it means that the circle does not intersect either the x-axis or the y-axis. In other words, the center of the circle must lie at some point (h, k) where h and k are not equal to zero.

The general equation of a circle with center (h, k) and radius r is:

(x - h)^2 + (y - k)^2 = r^2

Since we know that the circle has a radius of 5, we can substitute r = 5 into the equation:

(x - h)^2 + (y - k)^2 = 25

Now, we need to find values for h and k such that the circle has no x-intercepts and no y-intercepts. Since the x-intercepts occur when y = 0 and the y-intercepts occur when x = 0, we need to make sure that neither of these values satisfies the equation.

Let's first consider the x-intercepts. We want to make sure that the circle does not intersect the x-axis, which means that the y-coordinate of the center must be equal to the radius. In other words, k = 5. Now, the equation becomes:

(x - h)^2 + (y - 5)^2 = 25

Next, we need to make sure that the circle does not intersect the y-axis, which means that the x-coordinate of the center must be equal to the radius. In other words, h = 5. Now, the equation becomes:

(x - 5)^2 + (y - 5)^2 = 25

Therefore, the equation of the circle that has no x-intercepts, no y-intercepts, and a radius of 5 is:

(x - 5)^2 + (y - 5)^2 = 25

Answer:

Answer:

for any regular polygon, the sum of the exterior angles is always 360 degrees. In a regular polygon, all exterior angles have the same measure, which is equal to 360 degrees divided by the number of sides.

Let n be the number of sides of the polygon. Then we have:

360/n = 21.2

To solve for n, we can cross-multiply and simplify:

360 = 21.2n

n = 360/21.2

n ≈ 16.98

Since n must be a whole number (the number of sides in a polygon must be a whole number), the closest option is D) 17. Therefore, the polygon has 17 sides.

The percentage of muffins that were wheat muffins is as follows:

25/50 = 0.5

This indicates that wheat muffins accounted for 50% of all sales.

This ratio can be used to make a forecast about how many bran muffins will be sold over the course of the following 16 muffins. Therefore, we anticipate that roughly 50% of the subsequent 16 batches of muffins sold will be wheat muffins:
