The productivity of the painter is 0.66 up to two decimal places. It is attained by applying the knowledge of the division of two numbers and decimals to the provided problem.
What is decimal?
A decimal is a quantity that is distributed into two components, namely a whole and a fraction. A decimal number represents the numerical value lying in between the two integers. A decimal point (.) is used to segregate the fractional part from the whole part of a number.
E.g. 1.5, 0.06, 7.05, etc.
Calculation of the productivity of the painter
Productivity of the painter is obtained by dividing the number of houses painted by the number of days taken to paint them
The number of houses painted is 4
The number of days taken to paint 4 houses is 6 days
Productivity = 4 ÷ 6
= 0.666
Thus, the productivity of the painter is 0.66 up to two decimal places.

graph the equation y= 2/3x+5
the equation formula y=2/3x+5 is (3,-3).
In mathematics, what is an equation?Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
based on the available facts;
You might be wondering how, but we can start with that 5 at the end, which denotes the y-intercept.
If 0 is used in place of x, then y=2/30+5y=5
We shall receive the first coordinate as a result, which is (0,5).
Let's then consider the slope, which is 2,3. As you may already be aware, the slope is also known as
rise/run
; what do they mean by that is that the first top number tells you how many units you go up and the second one how many units you go right or how many units you go down and go left.
Now, I know this may seem complicated but let's make it clear. Since we know one coordinate, which is
(0,5)
, from that point by knowing the slope we can find a second point; this point is 2 points above and 3 to the right, which tells us that −5+2
points above gives us −3 and 3 points on the right gives us a new coordinate:
(3,−3)
And since we now know two coordinates, that is enough to draw the line and have the graph.

a piece of wire 100 inches long is cut into two pieces and each bent into the shape of a square. if the sum of the areas of the two squares is 400 in2, find the length of each piece of wire.
The length of the pieces of wire include 23.5425 inches and 75.4565 inches.
How to calculate the length?Given the total length of wire is
X+Y=100
Y=100-X
Then we bend the two pieces into squares so that the sides of each square are X/4 and (100-X)/4. Therefore
(X/4)² + [(100-X)/4]² =400
X² +10000-200X +X² =6400
X²-100X+1800=0
Solving the equation
X = 76.4565 inches and X=23.5425 inches
Therefore, the length of the pieces of wire include 23.5425 inches and 75.4565 inches.

How many gallons of 35% solution is needed by Eli ?Generally, It takes 0.125 gallons of a 35% solution to get the ratio you want.
Eli wishes to mix 0.5 gallons of a 10% acetic acid solution with a 35% solution to create a 15% acetic acid solution; thus, the calculation below must be done to calculate how many gallons of
5% solutions are required:
1 x 10 + 2 x 35 = 80
=> 80 ÷ 3 = 26.66
1x10 + 1x35 = 45
=>45÷ 2 = 2.5
1 x 10 + 0.5 x 35 = 27.5
=>27.5 ÷ 1.5 = 18.33
1 x 10 + 0.4 x 35 = 24
=>24 ÷ 1.4 = 17.14
1 x 10 + 0.2 x 35 =17
=> 17 / 1.2 = 14.16
1 x 10 + 0.3 x 35 = 20.5
=> 20.5/ 1.3 = 15.76
1 x 10 + 0.25 x 35 = 18.75
=> 18.75 / 1.25 = 15
1 / 2 = 0.5
0.25 / 2 = 0.125

Hence, the equation of exponential function is represented by y = A(Bˣ)
An exponential function is a mathematical function of the form f(x) = ax, where "x" is a variable and "a" is a constant called the base of the function and it must be greater than 0. The most commonly used exponential basis is the transcendental number e, which is approximately equal to 2.71828The equation in exponential form
y = A(Bˣ)
Case 1 :
x =0 y = 0.02
0.02 = A (B⁰)
A = 0.02
Case 2:
x = 1 y =0.04
0.04 = 0.02(B)
0.04 /0.02 = B
B = 2
Case 3 :
x = 2 y =0.08
0.08 = 0.02(2²)
0.08 = 0.08
Case 4 :
x = 3 y = 0.16
0.16 = 0.02(2³)
0.16 = 0.16
So, we have implemented the eqaution y = A(Bˣ)
We found the values of A & B, and also proved them in case 3 and case 4.
Hence, the equation of exponential function is represented by y = A(Bˣ)

The triangle with vertices located at U(-5 , 5), K(-5 , -1), and L(1 , 2) has its centroid located at (-3 , 2).
The centroid of a triangle is the point inside the triangle where the three medians intersect. The median of a triangle is the line the connects the midpoint of a side and the opposite vertex.
To get the centroid of a triangle, use the formula given by:
C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]
where C is the centroid of the triangle located at (x , y)
x1, x2, and x3 are the x-coordinate of the vertices of the triangle
y1, y2, and y3 are the y-coordinate of the vertices of the triangle
Let Point 1(x1 , y1) = U(-5 , 5)
Point 2(x2 , y2) = K(-5 , -1)
Point 3(x3 , y3) = L(1 , 2)
Plug in the values in the formula.

She receives 10% of her first $900 in sales and 15% of the balance of her sale.
This will be:
(10% × $900) + (15% × x) = 750
90 + 0.15x = 750
Collect like terms
0.15x = 750 - 90
0.15x = 660

How many of each type of ticket was sold if twice as many student tickets were sold as matinee tickets?
Number of matinee tickets = 900

Number of regular tickets = 5800
Algebra is the branch of mathematics that represents problems and situations in the form of mathematical expressions. It contains variables such as x, y, z, and operations such as addition, subtraction, multiplication, and division to form meaningful mathematical expressions.Algebra is used mostly in all areas of mathematics like trigonometry, calculus, and coordinate geometry. A simple example of an algebraic expression is 9x + 4 = 8. Algebra deals with symbols, and these symbols are related to each other by operators. It's not just a mathematical concept, it's a skill that we all use subconsciously in our daily lives.
Let x be the number of matinee tickets.
In that case, the number of student tickets is 2x.
The number of regular tickets is (8500-x-2x) = (8500-3x).
Total money
5x + 6*(2x) + 8.50*(8500-3x) = 64600
Simplifying and solving for x
5x + 12x - 8.50*3*x + 8.50*8500 = 64600
5x + 12x - 8.50*3*x = 64600 - 8.50*8500
Solving x , we get
x = 900
Number of matinee tickets = 900
Number of student tickets = 1800
Number of regular tickets = 8500 - (900+1800) = 5800

What is the tangent?A circle is a depiction with no sides or vertices.
It includes a radius as well as a center. The center is the point from which all other points just on circle are equidistant, and the distance between them equals the radius.
Let AC equal the tangent to the circle with center O.
OA ⊥ AC ....(The tangent has always been perpendicular to the radius.)
As, it is given that ∠OAC = 90° and ΔOAC is isosceles triangle.
Thus, ∠O = ∠C = x (say)
Now, using the triangle's angle sum property. We have it,
