The interest rate needed to make $3,472.32 from simple interest on a principal of $1,200.00 over 9 years is 21.04% per year.

Simple interest is expressed mathematically as;

A = P( 1 + rt )

Where A is accrued amount, P is principal, r is rate and t is the time period.

Given the data in the question;

Plug the given values into the simple interest formula and solve for r

A = P( 1 + rt )

r = (1/t)(A/P - 1)

r = ( 1/9 )( $3472.3/$1200 - 1)

r = ( 1/9 )( 2.8936 - 1)

r = ( 1/9 )( 1.8936)

r = 0.2104

Convert to percentage

r = 0.2104 × 100%

Rate r = 21.04%

Therefore, the interest rate of the loan is 21.04%.

The area of rectangle in square inches is 8649 inches .

The subject of mathematics known as mensuration is concerned with measuring geometric shapes and their various characteristics, such as length, volume, shape, surface area, lateral surface area, etc. In fundamental mathematics, learn about mensuration.

Mensuration is the name given to the area, volume, and length of various geometric shapes in mathematics. These shapes can be found in either two or three dimensions.

Mensuration is the process of calculating various shape parameters, such as the perimeter, area, and volume, whereas geometry is the study of the characteristics and relationships between the points and lines that make up different shapes.

the area of rectangle will be =  length *  width

therefore just substituting the values given in the question

thus ,

Step-by-step explanation:

f(4) = 27

The pounds of the less expensive tea used in the mixture is 10 pounds.

The correct option is Option(1) 10.

Given:

Price of less expensive tea = $2.00

Price of expensive tea = $5.00

Price of custom-blended tea = $4.25

The total price of 40 pounds of custom blended tea = 40 × $4.25

                                                                                       = $170

Let the pounds of the less expensive tea used in the mixture be x pounds.

So, the pounds of expensive tea = 40-x

Now, the equation is

2x + 5(40 - x) = 170

2x + 200 - 5x = 170

3x = 30

x = 10 pounds

Therefore, there are 10 pounds of less expensive tea.

Answer:

It's (7, 13) not sure how to explain that

The linear equation is:

y = -6*x + 59

The slope is -6, and means that each hour the distance decreases by 6 miles.

The y-intercept is 59, and it is the initial distance to the waterfall.

A general linear equation in the slope-intercept form is:

y = a*x + b

Where a is the slope (also called the rate of change) and b is the y-intercept.

We know that if the line passes through two points (x₁, y₁) and (x₂, y₂) then the slope is:

a = (y₂ - y₁)/(x₂ - x₁).

Here we can define the variables:

y = distance

x = hours.

Then we have two points (8, 11) and (9, 5).

So the slope is:

a = (5 - 11)/(9 - 8) = -6

This means that the distance to the waterfall decreases by 6 miles each hour.

Then the linear equation is like:

y = -6*x + b

To find the value of b we can use any of the given points, I will use (9, 5), this means that:

5 = -6*9 + b

5 = -54 + b

54 + 5 = b

59  = b

This is the y-intercept, and gives the initial distance to the waterfall.

The equation is:

y = -6*x + 59

Yes the triangles are congruent.

Step-by-step explanation:

You are going to move all the points 2 units to the left and  4 units up.

Look at the vertices of the triangle.  The points are (0,1) and (-5,0) and (2,-5).  If we moved all three of these points to places to the left and 4 up, they would be at (-2,4), (-7,4) and (0,-1)  This would make a image that is a congruent triangle.  You have just translated the original triangle 2 places to the left and 4 places up.

The principal amount was invested for 8 Years.

In the given question, it is stated that when $314 was invested as the Principal amount, it got an Interest of $175.84 at an interest rate of 7%. We have to find out the total period of time the principal amount was kept and got interested in in order to complete the interest amount of $175.84.

To calculate the Interest, we know that the formula for Simple Interest is:

=> S.I. = (P*R*T)/100, where P = Principal amount, R = Rate of Interest, and T is the Time period. Now, putting values in the formula we get:

=> S.I. = (P*R*T)/100

=> 175.84 = (314*7*T)/100

=> T = 17584/2198

=> T = 8

Hence, we get Invested Time for 8 years.

The amount for Kai's self employment taxes for the last month is  $407.745  .

In the question ,

it is given that

number of music lessons that Kai taught = 41

per music lesson charge = $65 .

Imagine putting a mirror on the page and adding a reflection. You must identify the line in which the shape is mirrored when describing a reflection. The sum of the transformations can be referred to as a single transformation.

Imagine putting a mirror on the page and adding a reflection. You must identify the line in which the shape is mirrored when describing a reflection. Every point of a shape will be separated from the line of reflection by the same amount as the reflected point is separated from the line.

There are occasions when a shape is altered in more than one step, such as when a rotation is followed by a reflection. Typically, the sum of the transformations can be referred to as a single transformation.

Enlargements are a particular kind of transformation where the original shape's size is altered by multiplying it by a scale factor to make it bigger or smaller. To employ a center of enlargement, lines must be drawn from the center via the original shape's vertices. They are known as ray lines.
