for 15 hours of work a plumber charges $330 if he charges the same amount for each hour of work which table shows the correct relationship between what he charges and the number of hours he works
Answer:
the 2 table
Step-by-step explanation:
330 ÷ 15 = 22 and in the 2 table is showing that
The table that shows the correct relationship between what he charges and the number of hours he works is the third table.
Given that,
The amount charged by the plumber is $330.And, there are the 15 working hours.
Based on the above information, the calculation is as follows:
[tex]= \frac{\$330}{15}[/tex]
= $22
Therefore we can conclude that the table that shows the correct relationship between what he charges and the number of hours he works is the third table.

How can we use area models to represent equal fractions?
Answer:
As we continue our series on developing fraction sense, hopefully by now you are feeling a little more confident and equipped. Learning about fractions doesn’t have to be scary, and it doesn’t have to mean hours of pencil and paper computations. Instead, the focus should be on deep understanding, using concrete, visual models. Today, I want to share a powerful visual, which students can use to compare, add, subtract, multiply and divide fractions: area models

how can i find a percentage if its not over 100? For example the fraction 4/25, how i could i turn that into a percent
Answer:
Step-by-step explanation:
to find percent you would simplify that fraction so that it’s a decimal (0.16) and multiply by 100 (16) and add a percent symbol so it would be 16%
basically the equation for finding percent would be
(x/y)100

Phil is riding his bike. He rides 42 miles in 4 hours, 52.5 miles in 5 hours, and 63 miles in 6 hours. Find the
constant of proportionality and write an equation to describe the situation. Let x represent the number of
hours.
The constant of proportionality is k =
The equation that describes the relationship is y =
If we take 42/4, or any other of the sets, you will get 10.5, which is k.
10.5 is the amount of miles travelled in 1 hour.
Since we just multiply time and miles to get y, our equation will just be in y=kx format. 10.5 * time is the same as writing 10.5x since x is the hours. y would be miles.
Constant of proportionality: k = 10.5
The equation: y = 10.5x

Which of the following is the graph of the solution set of y < –3 or y < 1?
Answer:
F
Step-by-step explanation:
Graph the 2 lines seperatly because it is not a double inequality...
The graph G represents the correct graph.
What is inequality? What is a mathematical function, equation and expression?inequality : Inequality is a relationship between two expressions or values that are not equal to each other is called inequality.function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is the solution set of the inequality -
y < - 3 or y < 1
The given solution set is -
(y < - 3) or (y < 1)
The solution set is -
[- 2, - 1, 0]
The graph G represents the correct graph.
Therefore, the graph G represents the correct graph.

It is about 1.62×10⁶ miles from Venus to Earth. It is about 5.4×10⁷ from Earth to Mars. How far is it total from Venus to Earth than Earth to Mars? Write your answer in scientific notation.
Answer:
-5.238- [tex]10^{7}[/tex]
or
Since the exponent of the scientific notation is positive, move the decimal point 6 places to the right.
1620000
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 8 N acts on a certain object, the acceleration of
the object is 2 m/s^2. If the acceleration of the object becomes 3 m/s^2,what is the force?
The Force equals to Mass times acceleration.
Thus, we now know that the mass of the object is 4 (unit of mass). Hence 8/2=4.
So, 3 times 2 equals to 6 N.
Am I correct?

5/7x - 1/3x = 8
Plz help me due today
Answer:
x=21
Step-by-step explanation:
hope that helps
Let's solve your equation step-by-step.
5/7x−1/3x=8
Step 1: Simplify both sides of the equation.
5/7x 1/3x=8
5/7x+ −1/3x=8
(5/7x+ −1/3x)=8(Combine Like Terms)
8/21 x=8
8/21x=8
Step 2: Multiply both sides by 21/8.
(21/8)*(8/21x)=(21/8)*(8)
