decimal form:
w= 1.64
mixed number:
w= 1 29/45
brainliest would be appreciated :)
Answer:
w=74/45
Step-by-step explanation:
(w-4/9)(-2/3)=-4/5
-2/3w+8/27=-4/5
-2/3w=-4/5-8/27
-2/3w=-108/135-40/135
-2/3w=-148/135
w=(-148/135)/(-2/3)
w=-148/135*-3/2,
w=74/45
sam wants to fence his rectangular garden plot along its length on the front side. The perimeter of the plot is 24 meters, and its length is 3 times its width
Answer:
Length: 12 meters
Step-by-step explanation:
Step 1:
Let us start with the formula of the perimeter of a rectangle, [tex]P=2l+2w[/tex], where l represents the length of the rectangle, and w represents the width of the rectangle.
We can set width as variable x. We are also given that the length is three times the width, hence it can be represented as 3x.
Step 2:
We can now write our equation and solve for x :
[tex]24=2x+2*2x\\24=2x+4x\\24=6x\\x=\fbox{4}[/tex]
We set x as width, so the width is 4 meters. However, in this problem we are looking for the length. The length is three times the width, so it would be [tex]\fbox{12}[/tex] meters.
I hope this helps! Let me know if you have any questions :)
Answer:
From the given information, there are two equations in terms of x and y:
2x + 2y = 24 (perimeter of the rectangular plot)
x = 3y (relationship between length and width)
The second equation is expressed in terms of x, so directly substitute the value of x into the first equation and find y:
2(3y) + 2y = 24
y = 3
Substitute y in the second equation to find x:
x = 3(3)
x = 9
The fencing cost is $25 multiplied by the length of the side Sam wants to fence: 25 × 9 = 225. Therefore, Sam needs to spend $225 to fence that side of his plot.

Answer:
✅On average Albany gets 20.967 inches rain pee year and Zachary gets 25.153 inches rain per year.
✅On average, it rains more in Zachary in a year.
Step-by-step explanation:
Mean annual rainfall on average = total amount of rainfall for the period of years ÷ 10
✔️Mean Annual rainfall for Albany (in.):
= (22.82 + 19.83 + 28.40 + 23.35 + 30.78 + 21.34 + 11.20 + 17.04 + 18.63 + 16.28) ÷ 10
= 20.967
✔️Mean Annual rainfall for Zachary (in.):
= (26.41 + 23.54 + 30.02 + 26.35 + 34.24 + 25.74 + 18.98 + 21.26 + 23.61 + 21.38) ÷ 10
= 25.153
✅Therefore, on average Albany gets 20.967 inches rain pee year and Zachary gets 25.153 inches rain per year.
✅On average, it rains more in Zachary in a year.
what is the equation of the line that is perpendicular to the line y = − x / 2 + 4 / 5 and passes through the point ( − 2, 6 ).
pls answer quickly
Answer:
y = 2x + 10
Step-by-step explanation:
Equation of the line is;
y = −(x/2) + (4/5)
Slope here is m = -½ following the equation y = mx + c
Now, for a line perpendicular to it, the slope will now be; m = -1/(-½) = 2
To pass through the point ( − 2, 6 ), let's find C and it will be;
6 = 2(-2) + c
6 = -4 + c
c = 6 + 4
c = 10
Thus equation is;
y = 2x + 10

h = 0.k = 20.a = -0.12.How to write a function.Generally, the vertex form of a quadratic equation can be used to model or write an equation of the function of a graph.
Mathematically, the vertex form of a quadratic equation is given by this formula:
y = a(x - h)² + k
Where:
h and k represents the vertex of the graph.
Note: The sign on "a" indicates whether the quadratic equation opens up or opens down.
Based on the complete information, we can deduce that the values of the constants in the vertex form of the quadratic equation are:

Answer:
4th option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{3}{5}[/tex] x - 6 ← is in slope- intercept form
with slope m = [tex]\frac{3}{5}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{3}{5} }[/tex] = - [tex]\frac{5}{3}[/tex]
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - [tex]\frac{5}{3}[/tex] and (a, b ) = (- 2, 5 ) , then
y - 5 = - [tex]\frac{5}{3}[/tex] (x - (- 2) ) , that is
y - 5 = - [tex]\frac{5}{3}[/tex] (x + 2)

If we were to divide the shape into a rectangle and triangle, we would have the base of the triangle as 9 because two sides of the rectangle are equal, and 7 for the side because two sides of rectangle are equal and 14/2 is 7. Now we have two sides of a triangle 9 and 7. We know X is the hypotenuse because it is opposite to the right angle. We will plug it into the pythagorean theorem.

A. What is the sum of all the interior angles in the kite?
B. Copy the kite and draw the diagonals. What is the measure of the angle at which the diagonals intersect?
Answer:
A. 360 degrees
B. 360 degrees all the way around but each individual one is 90 degress
Step-by-step explanation:
Answer:
Step-by-step explanation:
B: the kite's diagonals intersect each other at a 90o degree angle.
A: It should come to 360. Let's if that happens.
Take the top angle (88) first. Notice that if you draw in both diagonals, the will form Isosceles triangles. Let's deal with the shorter diagonal first.
The two angles at the base of the shorter diagonal are equal. That's because the sides opposite them are equal.
2x +88 = 180 Subtract 88 from both sides.
2x = 92 Divide by 2
x = 46
Now lets look at the long narrow legs of the bottom isosceles triangle.
2x + 50 = 180 Subtract 50 from both sides
2x = 130 divide by 2
x = 130 /2
x = 65
Now add up all the angles that make up the interior of the kite.
Total = 46 + 46 + 65 + 65 + 50 + 88
Total = 360 just as it should.

A rectangle has sides measuring (2x + 7) units and (5x + 9) units.
Part A: What is the expression that represents the area of the rectangle? Show your work.
Part B: What are the degree and classification of the expression obtained in Part A?
Part C: How does Part A demonstrate the closure property for polynomials?
Part A
Use the FOIL rule to expand out the expression below
(2x+7)(5x+9)
2x*5x + 2x*9 + 7*5x + 7*9
10x^2 + 18x + 35x + 63
10x^2 + 53x + 63 is the final answer for part A
==========================================================
Part B
The degree is 2. This is a quadratic trinomial.
The degree is simply the largest exponent after expanding everything out. The degree directly determines the type of polynomial. Since the degree is 2, we have a quadratic. The polynomial is a trinomial because it has 3 terms.
==========================================================
Part C
Imagine we had a machine in which we deposit 2 coins into it. One would happen on either side. After the coins are deposited, a third coin pops out. The 2 coins going in and the third coin coming out are the same currency. This represents an example of closure.
In mathematics, the idea of closure is taking any two objects of the same type, applying an operation on them, and getting the same type of object as the input.
For example, we could take two whole numbers and multiply them together. The result is always a whole number. The set of whole numbers is closed under multiplication because you can't leave the set (hence the gate is closed not letting anything out).
Similarly, taking any two polynomials and multiplying them together will always lead to some other polynomial. Part A shows this in action because (2x+7), (5x+9) and 10x^2 + 53x + 63 are all polynomials.
[tex]\rm 10x^{2} + 53x + 63[/tex] is the expression that represents the area of the rectangle. This is a trinomial expression.
What is a quadratic equation?A quadratic equation is the polynomial of second degree in one variable only. The standard form of a quadratic equation is [tex]\rm ax^{2} +bx+c=0[/tex]
Where, x is the variable and a,b, and c are real numbers.
Part A
Let length of a rectangle = (2x+7)
Let width of a rectangle = (5x+9)
The area of the rectangle = length × width
= (2x+7)(5x+9)
= 2x × 5x + 2x × 9 + 7 × 5x + 7 × 9
= [tex]\rm 10x^{2} + 18x + 35x + 63[/tex]
Therefore, [tex]\rm 10x^{2} + 53x + 63[/tex] is the expression that represents the area of the rectangle.
Part B
The degree is 2 in the expression. This is a trinomial expression.
The degree is simply the largest exponent. The degree directly represents the type of polynomial. Since the degree is 2. The polynomial is a trinomial because it has 3 terms.
Part C
Applying multiplication operations such that taking any two polynomials and multiplying them together will always lead to some other polynomial. Part A shows this multiplication because (2x+7), (5x+9) and [tex]\rm 10x^{2} + 53x + 63[/tex] are all polynomials.
