How would you simplify the expression represented by the diagram below? Four figures. The first consists of 4 squares each labeled 1. The second consists of 2 rectangles each labeled c. The third consists of 2 squares each labeled 1. The fourth consists of one rectangle labeled c.

Answers

Based on the description of the diagram, we get simplified expression is 6 + 3c.

Describe Algebraic Expression?

An algebraic expression is a mathematical phrase that consists of variables, constants, and arithmetic operations (such as addition, subtraction, multiplication, and division), as well as exponentiation and roots. These expressions are used to represent mathematical relationships and formulas in a concise and standardized way.

Based on the description of the diagram, we can simplify the expression as follows:

There are 4 squares labeled 1, so their total value is 4.

There are 2 rectangles labeled c, so their total value is 2c.

There are 2 squares labeled 1, so their total value is 2.

There is 1 rectangle labeled c, so its value is c.

Therefore, the expression represented by the diagram simplifies to:

4 + 2c + 2 + c

6 + 3c

So the simplified expression is:

6 + 3c.

Parallel lines problem:

Parallel lines have the same slope, so the answer should give a pair of lines whose slope is equal to that of line m, i.e., 2/3.

The only line that fits the bill is line p, whose slops is (8-6)/(12-9) = 2/3; none of the other lines has a slope of 2/3. Thus, b would be the correct answer here for the first image.

The height of a cone, h = 10 m

Radius of the cone, r = 4 m

It can be assumed to find the volume of the cone. Th formula for the volume of a cone is given by :

[tex]V=\dfrac{1}{3}\pi r^2 h\\\\V=\dfrac{1}{3}\pi \times (4)^2\times 10\\\\V=167.55\ m^3[/tex]

5 The Raven Club sold tickets to the local fall festival. On day one, they sold 50 child tickets and 75 adult
tickets and the total was $525. On day two, they sold 45 child tickets and 65 adult tickets and the total
was $460. What was the cost of the adult tickets?

Answers

Answer:

Y = 6

Step-by-step explanation:

On the first day of ticket sales the school sold 3 adult ticket and 8 student tickets for a total of $72. The school took in $152 on the second day by selling 7 adult tickets and 16 student tickets. How much is a student ticket?

Day 1: 3x + 7y = 72

Day 2: 7x + 16y = 152

This becomes a system of equations.

3x+8y=72

3x+8y+−8y=72+−8y (Add -8y to both sides)

3x=−8y+72

3x/3 = −(8y+72)/3

X = (-8/3) y + 24

Substitute (-8/3) y + 24 for x in7x+16y=152:

7(-8/3 y + 24) + 16y = 152

-8/3 y + 168 = 152 (Simplify both sides of the equation)

-8/3 y + 168 − 168 = 152 + (−168) (Add -168 to both sides)

-8/3 y = -16

(-8/3 y)/(-8/3 y) = -16/ -8/3 y (Divide both sides by (-8)/3)

y = 6

You will then use this model to discuss the changes in potential and kinetic energy of the cart as it moves along the track.Background InformationThe two most common forms of energy are potential energy and kinetic energy. Potential energy is the stored energy an object has due to its position. Kinetic energy is the energy an object has due to its motion. An objects kinetic energy changes with its motion, while its potential energy changes with its position, but the total energy stays the same. If potential energy increases, then kinetic energy decreases. If potential energy decreases, then kinetic energy increases.Potential energy related to the height of an object is called gravitational potential energy. Gravitational potential energy is directly related to an objects mass, the acceleration due to gravity, and an objects height.Materials One poster board per student Drawing utensilsAssignment InstructionsStep 1: Prepare for the project.a) Read the entire Student Guide before you begin this project.b) If anything is unclear, be sure to ask your teacher for assistance before you begin.c) Gather the materials you will need to complete this project.Step 2: Create your poster.a) On the poster board, draw a roller coaster track that starts with one large hill, then is followed by a valley and another, smaller hill.b) Draw a cart in four positions on the track as outlined below.i.
