where A = 238
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as = P
Now , the value of P is given by
Let the unknown variable in the equation be A
A + ( 9 + 8 ) = ( 15 x 9 ) + ( 15 x 8 )
On simplifying the equation , we get
The value of A + 17 = 135 + 120
On adding the values in the equation , we get
The value of A + 17 = 255
On subtracting 17 on both sides of the equation , we get
The value of A = 238
Therefore , the value of A is 238
Hence , The value of the equation A + ( 9 + 8 ) = ( 15 x 9 ) + ( 15 x 8 ) is 238

Patrick invested money into a special savers bank account. Each year money in the account earns 4% interest. After one year, the total amount of money in the account was €291.20 How much did Patrick invest?
Answer: Patrick invested €7,280 in the special savers bank account.
Step-by-step explanation:
If the money in the bank account earned 4% interest after one year, then the amount of interest earned is 4/100 * the amount invested. We can write this as an equation as follows:
4/100 * amount invested = €291.20
Solving for the amount invested, we get:
4/100 * amount invested = €291.20
amount invested = €291.20 / (4/100)
= €291.20 / 0.04
= €7,280
Therefore, Patrick invested €7,280 in the special savers bank account.

What is slope?
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line.
We are told that the slope of the line is -3/5.
Thus, m = -3/5
Formula for slope between two coordinates is;

To indirectly measure the distance across a lake, Bilquis makes use of a couple
landmarks at points R and S. She measures QU, US, and TU as marked. Find the
distance across the lake (RS), rounding your answer to the nearest hundredth of a
meter.
The measure of distance RS, if The sides QU = 140 m, US = 115 m, TU = 104.55 m, rounding to the nearest hundredth of a meter, is 200 m.
What is the triangle?Triangles are basic three-sided polygons with three internal angles. It is one of the basic geometric shapes, symbolized by the symbol, and has three vertex connections.
Given:
The sides QU = 140 m, US = 115 m, TU = 104.55 m
As you can see, the triangle QRS and triangle QTU are similar, thus the ratio of their sides will be equal,
QU / QS = TU / RS
140 / 140 + 115 = 104.55 / RS
140 / 255 = 104.55 \ RS
RS = 104.55 × 255 / 140

Jump up! Refer to Exercise 6. Suppose that the corrected long-jump distances are converted from centimeters to meters (note that 100 cm = 1 m). (a) What shape would the resulting distribution have? Explain your answer. (b) Find the mean of the distribution of corrected long-jump distance in meters. (c) Find the standard deviation of the distribution of corrected long-jump distance in meters.
Shape would the resulting distribution have very symmetric distribution with a single peak was found to be the corrected long-jump distances in centimeters distribution's shape.
Define symmetry.In common parlance, the term "symmetry" describes a sense of lovely proportion and balance. A more exact meaning of "symmetry" can be found in mathematics, where it typically refers to an object that is unaffected by certain transformations like translation, reflection, rotation, or scaling.
Given,
100 cm = 1 m
Xₙ = 557.3 cm
Divide each centimeter number by 100 to convert the corrected long jump distances from centimeters to meters.
A very symmetric distribution with a single peak was found to be the corrected long-jump distances in centimeters distribution's shape.
The distribution's structure is unaltered when each value in the data is divided by 100 since there are no changes to the relationships between any two pieces of data.
Since there is just one peak in this example, the corrected long-jump distances in meters distribution likewise has an almost symmetric form.

Using the Corresponding Angle Theorem, ∠m = 23 degree. So, the option A is correct.
In the given question, lines n and o are parallel and are cut by the transversal p.
We have to find the measure of ∠m and choose the correct option.
As we know that;
When two parallel lines are intersected by another line, corresponding angles are the angles that are formed in matching corners or corresponding corners with the transversal.

A numerical variable is a type of data that is expressed as a number or numerical value. It is typically used to measure a quantitative value such as height, weight, age, income, distance, quantity, or speed. Examples of numerical variables include population size, test scores, stock prices, or sales figures. Numerical variables can also be discrete or continuous.

The aftertax cost of debt to Mojo Mining, given the company tax rate, and the maturity term of the bond, is F. 4. 58 %
How to find the aftertax cost of debt ?First, find the yield on the bond. This yield can be found by the Rate function on Spreadsheet.
N = 18 years x 2 = 36 semi annual periods
PMT = 6.66% / 2 x 2, 000 = $ 66. 60

The spreadsheet would show a result of 3.05 % per semi annum. The annual rate is therefore:
= 3.05 % x 2
= 6.10 %
The aftertax cost of debt to Mojo Mining is therefore:

Sophie has $800 in a saving account that earns 5% interest per year. The interest is not compounded. How much will she have in 1 year
Answer:
If Sophie has $800 in a saving account that earns 5% interest per year and the interest is not compounded, then after one year she will have $840 in her account. This is because 5% of $800 is $40, and when we add this to the initial amount of $800, we get $840.
In general, if a saving account earns x% interest per year and the initial amount in the account is y dollars, then after one year the account will have y + (x/100) * y dollars. For example, if the interest rate is 5% and the initial amount is $800, then the final amount would be $800 + (5/100) * $800 = $840.

The hypotenuse of a right triangle is 13 ft long. The shorter leg is 7 ft shorter than the longer leg. Find the side lengths of the triangle.
Answer:
Since the length of a side of a triangle must be a positive number, the only solution that makes sense is $x = \frac{14 + \sqrt{-764}}{8}$. The length of the shorter leg is then $y = x - 7 = \frac{14 + \sqrt{-764}}{8} - 7 = \frac{7 + \sqrt{-764}}{8}$.
Therefore, the side lengths of the triangle are $\frac{7 + \sqrt{-764}}{8}$ and $\frac{14 + \sqrt{-764}}{8}$.
