Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1 and 3/5 doors. How many liters of paint are needed for one door? Consider drawing a model to help you solve the problem.
Answers
Answer:
1 and 1/4 liters of paint are needed for one door
Step-by-step explanation:
You can eliminate each answer choice out. For '4/5 liters' you know that if that amount was used, it wouldn't be reasonable since it would mean that the more was used for the other 3/5 door. 3 and 1.5 would be too much since it is over 2 liters. 2 liters wouldn't be logical since you paint 1 and 3/5 of a door and you only used 2 liters, no more or no less, basically what would you use for the other 3/5 door if this was the answer.
Hope this helps!

James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply.
7 x + 4 and 3 x + 5 + 4 x minus 1
When x = 2, both expressions have a value of 18.
The expressions are only equivalent for x = 4 and x = 6.
The expressions are only equivalent when evaluated with even values.
The expressions have equivalent values for any value of x.
The expressions should have been evaluated with one odd value and one even value.
When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
The expressions have equivalent values if x = 8.

Which of the following numbers is not part of the solution x ≤ -2
A. -2.45
B. -2
C. -8
D. -1.76
Answers
Answer:
D.
Step-by-step explanation:
In order for it to be the solution, it must be less than or equal to -2. D (-1.76) is bigger than -2, which means it is not a part of the solution.
Answer:
D
Step-by-step explanation:
First of all, let's try all of the options available.
We know that x must be LESS THAN or EQUAL to -2
So, let's get on with it!
Option A:
Is -2.45 LESS THAN or EQUAL to -2?
Well, according to the number line, if the number is left of the number that you are comparing, -2 then it is less than.
So this option is alright.
Option B:
-2 is not LESS THAN but ONLY EQUAL to -2.
So this option I THINK is alright, but am not sure. But I think it is alright because if it is less than and equal to, then that means it ALSO INCLUDES -2.
Option C:
Again, -8 is located to the LEFT side of -2, which means -8 IS LESS THAN or Equal to -2.
So this option is alright.
Option D:
-1.76 is to the RIGHT side of -2, which means it is GREATER than -2.
So this option is CUT OFF
Hope this helps.

Step-by-step explanation:
The slope of a line passing through the two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1x2−x1.
We have that x1=3, y1=2, x2=0, y2=−1.
Plug the given values into the formula for slope: m=(−1)−(2)(0)−(3)=−3−3=1.
Now, the y-intercept is b=y1−m⋅x1 (or b=y2−m⋅x2, the result is the same).
b=2−(1)⋅(3)=−1.
Finally, the equation of the line can be written in the form y=mx+b.
y=x−1.
Answer:
The slope of the line is m=1.
The equation of the line in the slope-intercept form is y=x−1.
The equation of the line in the point-slope form is y−2=1(x−3).
The equation of the line in the point-slope form is y+1=1x.
The general equation of the line is x−y−1=0.

Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.
Sarah can use the expression 5(2j + 3 + j) to represent the amount of money she can earn.
Part 1: Writing Expressions
Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.
Translate the algebraic expression you created in Question 1 to a verbal expression.
Part 2: Writing Equivalent Expressions
You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.
Use either the commutative property or combine like terms to create an equivalent expression.
Use the distributive property to create an equivalent expression.
Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression. Show all your work for complete credit.
Part 3: Finish the Story
Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did Sarah earn?
Choose a method to present your assignment. You may submit your work in a Word Document or you may choose to develop a PowerPoint presentation or video recording of yourself. Use your creativity! Make sure to include the information from all three parts in your Word Document or presentation.

why dividing by 0 is undefined?
Answers
Answer:
In standard math, the articulation has no importance, as there could be no number which, when duplicated by 0, gives a (expecting to be a ≠ 0), thus division by zero is indistinct. Since any number increased by zero will be zero, the articulation 00 is additionally unclear; when it is the type of a breaking point, it is a vague structure.
Step-by-step explanation:
Answer:
In ordinary arithmetic, the expression has no meaning, as there is no number which, when multiplied by 0, gives a (assuming a ≠ 0), and so division by zero is undefined. Since any number multiplied by zero is zero, the expression 0. 0 is also undefined; when it is the form of a limit, it is an indeterminate form.

You walk across the bridge, while your friend walks halfway around the pond to meet you at the other side of the bridge. How much farther does your friend walk? Round your answer to the nearest hundredth. Use 3.14 for π.

C= πd, where C means circumference and d means diameter. 0.75 is the diameter of the pond, so 3.14 × 0.75 gives you 2.355mi.

What is the Volume of the box 385 cubes?
Answers
Answer:You can calculate the volume of a box by multiplying length x width x height. Using the example of the single wall box this will be 102 x 102 x 102 which equals 1,061,208 cubic millimeters (㎣).
Step-by-step explanation:
The Volume of the box is 385/27 inch³.
What is Volume?The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
Many forms have various volumes. We have studied the several solids and forms that are specified in three dimensions, such as cubes, cuboids, cylinders, cones, etc., in 3D geometry. We will discover how to find the volume for each of these shapes.
Length = 11/3 inch
width - 5/3 inch
Height = 7/3 inch
So, the Volume of cuboidal box
= l w h
= 11/3 x 5/3 x 7/3
= 385/ 27 inch³
Also, Number of small cube = Volume of box/ Volume of small cube
385 = Volume of box / (1/27)
Volume of box = 385/ 27 inch³
