7 × 9 = (? × 9) + (? × ?)
7 × 9 = (3 × 9) + (4 × 9) or (4 × 9) + (3 × 9)
The required numbers are 3, 4, and 9 to create the expression that is equal to 7 × 9.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
We have been given numbers are 2, 3, 4, 6, 8, and 9.
To determine numbers create a different expression that is equal to 7 × 9.
Here substitute the numbers 3, 4, and 9, and we get
⇒ 7 × 9 = (3 × 9) + (4 × 9) = 63
⇒ 7 × 9 = (4 × 9) + (3 × 9) = 63
Therefore, the required numbers are 3, 4, and 9 to create the expression that is equal to 7 × 9.

Heather invested $25,800 in an account that pays 4% simple interest. If she invests the money for 10 years, how much will she have?
Answer:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year.
Solving our equation:
A = 25800(1 + (0.04 × 10)) = 36120
A = $36,120.00
The total amount accrued, principal plus interest, from simple interest on a principal of $25,800.00 at a rate of 4% per year for 10 years is $36,120.00.

side BC = side AB
so their base angles that is ∠A = ∠C = (3x+20)°
now, total measure of the angles of a triangle is 180° & ∠B = x°
Now,
m∠A + m∠B + m∠C = 180
⇒ 3x + 20 + x + 3x + 20 = 180
⇒ 7x + 40 = 180
⇒ 7x = 140

Do all perpendicular lines have negative reciprocal slopes?
Not necessarily, the more correct definition is opposite reciprocal slopes.
The example used is how horizontal and vertical lines are parallel. Horizontal lines have a slope of 0, also written as 0/1. However, vertical lines have an undefined slope, which isn't necessarily negative. It has a slope of 1/0, which is undefined. In this case, the reciprocal isn't negative.
In all other cases (1 and -1, 2 and -1/2, etc.) yes, the perpendicular pairs are negative and reciprocal.

A rancher needs to enclose two adjacent rectangular corrals, one for cattle and one for sheep. If the river forms one side of the corrals and 270 yd of fencing is available, find the largest total area that can be enclosed.
The largest total area that can be enclosed is 4050 square yards.
Let's the length of the rectangular corral for cattle as x and the length of the rectangular corral for sheep as y.
For the cattle corral:
- Two sides with length x.
- One side with length y.
For the sheep corral:
- Two sides with length y.
- One side with length x.
As, the total fencing required is 270 yards
2x + y + 2y + x = 270
3x + 3y = 270
x + y = 90
Now, area of a rectangle is given by the formula A = length × width.
For the cattle corral = x × y
For the sheep corral= y × x
So, the total area is
= x × y + y × x
= 2xy
From this equation, x + y = 90
x = 90 - y.
Substituting this into the equation for A total:
A total = 2(90 - y)y = 180y - 2y²
To find the maximum area, take the derivative of A_total with respect to y and set it equal to zero.
\(\dfrac{dA_{total}}{dy}\) = 180 - 4y = 0
Solving for y:
180 - 4y = 0
4y = 180
y = 45
Substituting this value of y back into the equation x + y = 90:
x + 45 = 90
x = 45
Therefore, the dimensions that maximize the total area enclosed are x = 45 and y = 45.
So, the maximum area
=2 (45) (45)
= 4050 square yards

Find the length and width of a rectangle that has the given perimeter and a maximum area? Perimeter: 164 meters
The request dimensions of the rectangle for maximum area are,
Length of perimeter is, \(l = 41 m . ,\)
Width of perimeter is, \(w = 41m\)
The perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape. It is measured in linear units of measurement like centimeters, meters, inches, or feet.
Let \(l\) and \(w\) denote the length and width of the Rectangle.
Its Perimeter is \(2(l+w)\), which is given to be, 164.
\(l+w\) = 164/2
\(l+w\) =82 (Equation-1)
Now, Area \(A\) of the Rectangle, is, given by,
\(A = lw\)
We can substitute equation-1,
\(A = l(82-l)\)
\(A = 82l-l^{2}\)
which is a function of \(l\),
So let us,
Write it as,
\(A(l) = 82l-l^{2}\) (Equation-2)
We are request to maximize \(A\).
We know that, for \(A_{max}\), \(A^{|}l\) = 0 , and \(A^{||} l\) < 0
We can equation-2,
\(A^{|}l\) = 0 ⇒ \(82-2l = 0\)
\(l = \frac{82}{2}\)
\(l = 41\)
Further,
\(A(l) = -2\) < 0, ∀\(l\) , and in particular, for \(l = 41\) , too.
Thus, \(l = 41\) gives \(A_{max}\)
Hence, the request dimensions of the rectangle for maximum area are,
\(l = 41 m . ,\) and \(w = 82 -l = 41m\)
Therefore,
The request dimensions of the rectangle for maximum area are,
Length of perimeter is, \(l = 41 m . ,\)
Width of perimeter is, \(w = 41m\)
