The expression to determine the number of bags is 2/3 x = 2 1/2 and the number of bags requited is 3 3/4 bags
How to write the expression of the problemInformation from the problem
Maya rakes up the leaves and wants to put them into bags that hold 2\3 of a cubic yard
she rakes 2 1\2 cubic yards of leaves
one bag = 2/3 cubic yard
total leaves raked = 2 1/2 cubic yard
the number of bags required is how many 2/3 cubic yards are there in 2 1/2 cubic yard. this is solved by division
let the number of bags be x
2/3 cubic yard * x = 2 1/2 cubic yard
2/3 x = 2 1/2
x = (2 1/2) / (2/3)
x = 15/4
x = 3 3/4 bags

What is regular polyhedron ?A polygon that is based on the solid in the three dimensions is known as a polyhedron. It has flat faces, straight edges and corners. A polyhedron is something like a cube, prism, or pyramid. Cones, spheres, and cylinders do not have polygonal sides, hence they are not polyhedra. Polyhedron is also the name of the polyhedron's plural form. They are classified as prisms, pyramids, and regular polyhedra. Polyhedra include, for instance, cubes (regular polyhedrons), square prisms, triangular prisms, square pyramids, and square pyramids.

5. Find the Point that divides line segment AB two-thirds of the way from A to B. - A(-3,5) B(3,-1)
Answer:
The answer is B(3, -1)
Step-by-step explanation:
I did this before.
Points A, B, and C are collinear. Point B is between A and C. Find the value of x.
AC = 24
AB = 2x + 1
BC = 3x − 2
Responses
A 55
B 33
C 99
D 7
Therefore, the value of the given equation of x comes out to be x =5.
What kinds of equations are there?Equations can be classified as either identities or conditioned equations. For each amount of the variables, an identity is true. Only specific values of the variables make a conditional equation legitimate. The equality sign ("="), which separate the two expressions, is a symbol for an equation.
Here,
Given data: A, B, and C are parallel, B is located between A and C, AC equals 24, AB equals 2x+1, and BC equals 3x-2.
In the event where A, B, and C are collinear and B is positioned between A and C, we obtain
Replace the given equation with AC = 24, AB = 2x+1, and BC = 3x-2.
AB plus BC equals AC
=> AC= AB + BC
On combining like terms we get
=> 2x+1 + 3x-2 = 24
=> 5x -1 =24
=>5x =25
=>x =5
Therefore, the value of x comes out to be x =5.

The midpoint of the line AN is (3(1/2) , -1).
What is midpoint?
The midpoint is located halfway between the two end points. Its x and y values are in the middle of the two x and y values.Add both "x" coordinates, divide by 2, and add both "y" coordinates, divide by 2 to calculate it.Midpoint of the line(x , y) = (x₁ + x₂ / 2) , (y₁ + y₂ / 2)
x₁ = 2, x₂ = 5
y₁ = -3, y₂ = 1
So,
Midpoint of the line(x , y) = (2+5/2) , ((-3)+1 / 2)
= (7/2 , -2/2)
= (7/2, -1)

Selena and Luis are building a model bridge out of balsa wood. To make a strong bridge, they create each post by laying out two long wooden poles horizontally, as shown in the diagram, and connecting them with smaller strips of balsa wood laid diagonally in a triangle pattern. The triangle pattern is continued down the entire length of the wooden poles.
The poles are 12 centimeters apart, and each small strip of balsa wood is 13 centimeters long.
If the two poles are each 100 centimeters long, how many small strips of balsa wood will they need to connect them?
If the two poles are each 100 centimeters long, The number of small strips of balsa wood they will need to connect them is: C. 20.
How to find the number of small strips?Using Pythagorean theorem formula to find triangle side a.
a=√b²+c²
a = √ 13² - 12²
a = √ 169 - 144
a = √ 25
a = 5
Hence, the number of small strips of balsa wood they need to connect them is:
100 / (2a)× 2

Use synthetic division to find the result when 2x^3-14x^2+15x-18 is divided by x-6.
The Answer:
2x^2−2x+3
The result of the expression (2x³ - 14x² + 15x - 18) ÷ (x - 6) on dividing will be (2x² - 2x + 3).
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The expression is given below.
⇒ (2x³ - 14x² + 15x - 18) ÷ (x - 6)
The factor of the expression (2x³ - 14x² + 15x - 18) is given as,
⇒ (2x³ - 14x² + 15x - 18)
⇒ 2x³ - 12x² - 2x² + 12x + 3x - 18
⇒ 2x²(x - 6) - 2x (x - 6) + 3(x - 6)
⇒ (x - 6)(2x² - 2x + 3)
Then the expression is written as,
⇒ (2x³ - 14x² + 15x - 18) ÷ (x - 6)
⇒ [(x - 6)(2x² - 2x + 3)] / (x - 6)
⇒ (2x² - 2x + 3)
The final solution of the expression (2x³ - 14x² + 15x - 18) ÷ (x - 6) on dividing will be (2x² - 2x + 3).

There are 3 fewer yellow beads than red beads. There are twice as many green beads as yellow beads. Write expressions for the number of red, green, and yellow beads.
Answer:
yellow = red - 3 and green = yellow x 2 and red = yellow + 3
or
green= (red-3) x 2
Step-by-step explanation:
Three fewer yellow than read is the same as saying red -3
twice as many green as yellow is the same as yellow x 2
if green is yellow x 2 you can substitute yellow for the equation to find yellow
you can flip the equation for yellow around by doing inverse operations. To have the equation equal red you need to move the three by doing its inverse. The opposite of subtraction is addition so you'd add 3 to each side, getting rid of the -3 and isolating the red to make the equation red=yellow+3

What is center of a circle?
A circle's center is the point from which all of the distances to the other points on the circle are equal. The radius of the circle is the measurement at issue.
Given equation of circle is

In a company, 85% of the workers are men. If 405 people work for the company who aren't men, how many workers are there in all? Use pencil and paper. Show two different ways that you can solve this problem.
Answer:
2700
Step-by-step explanation:
1st method:
let x be the number of all workers in the company
then, the number of female workers will be x-0.85x = 0.15x
0.15x = 405
x = 405/0.15 = 2700
2nd method
we know that the 405 people who aren't men make 15% (100%-85%) of the whole number of workers, by using proportions:
15% - 405
100% - X
X = (100% * 405 )/15% = 2700
Use the first five terms of the trigonometric series to approximate the value of sin 4pi/5 to four decimal places. Then
compare the approximation to the actual value.
The first five terms of the given trigonometric series are (C) 0.5884, 0.5878.
What is a trigonometric series?
A mathematical series where the sines and cosines of integral multiples of a variable angle are used to connect the components.
Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent are the six trigonometric functions.
Below is a graph of the first five terms in the trigonometric series of sin:
sinx = x - x³/3! + x⁵/5! - x⁷/7! + x⁹/9! .......
Insert x = 4π/5
sin4π/5 = 4π/5 - (4π/5)³/3! + (4π/5)⁵/5! - (4π/5)⁷/7! + (4π/5)⁹/9! .......
Upon resolution, we determine an approximate value of:
sin4π/5 = 0.5884
Find the true value now:

A company that manufactures golf balls produces a new type of ball that is supposed to travel significantly farther than the company’s previous golf ball. To determine this, 40 new-style golf balls and 40 original-style golf balls are randomly selected from the company’s production line on a specific day. A golf pro takes the balls to the driving range and hits the 40 new-style golf balls first and then the 40 original-style golf balls. The distance each ball travels is recorded. At the end of the session, the mean distance traveled for the new type of golf ball was found to be significantly greater than the mean distance for the original-style golf ball.

The value of 'x' for the given (alternate exterior angles) is found as 9.
Explain the term alternate exterior angles?The pair of angles the outside of the two parallel lines but on the opposing side of the transversal are known as alternate exterior angles.A transversal that crosses two parallel lines produces alternate exterior angles. They form two pairs (total four angles) of alternate outside angles since they are situated "outside" the pair of parallel lines but on different sides of the transversal.For the stated question.
-1 + 14x = 12x + 17 (alternate exterior angles)
Simplifying,
14x - 12x = 17 + 1
2x = 18
x = 9
