The populations of Cities A and B are 1.6 x 10^5 and 1,070,000, respectively. The population of City C is twice the population of City B. The population of City C is how many times the population of City A?
Answers
Answer:
13
Step-by-step explanation:
First find the population of city c 1,070,000 times 2 = 2140000
Round 2140000 to the nearest hundred thousands = 2,100,000
Third find how many places the decimal moves which is 6 places
Fourth scientific notation of 2,100,00 is 2.1 times 10^6
Fifth divided city c by the population of city a
2.1x 10^6 divided by 1.6 x 10^5
2.1 / 1.6 rounded is 1.3
10^6 divided by 10 ^ 5 is 10
Therefore 2.1 x 10^6 divided by 1.6 divided by 10^5 equals 1.3 times 10 = 13
The population of city c is about 13 times the population of city a

General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
y = 5x - 3
3x - 2y = 27
Step 2: Rewrite systems
Define: 3x - 2y = 27Add 2y on both sides: 3x = 2y + 27Divide 3 on both sides: x = 2/3y + 9Step 3: Redefine
y = 5x - 3
x = 2/3y + 9
Step 4: Solve for y
Substitute in x: y = 5(2/3y + 9) - 3Distribute 5: y = 10/3y + 45 - 3Combine like terms: y = 10/3y + 42Subtract 10/3y on both sides: -7/3y = 42Divide -7/3 on both sides: y = -1810 x what equals 66??

Answer:
1. B. it always stays the same length it will just have different points
2. yes you did do number 2 correctly
Step-by-step explanation:
Answer:
Please check the explanation.
Step-by-step explanation:
Question 1)
Please note that when a translate any object on the coordinate plane, we are just sliding a figure on the coordinate plane. The shape, orientation, or size do not change.
Hence, if you translate a line up 4 and to the left 2, its image will look like a line that is the same exact length.
Question 2)
Given the original point C(-1, -4) and its image C'(-6, 3).
It is clear that the coordinates of the image C'(-6, 3) is the result of translating the C(-1, -4) to the left 5 and down 7.
So the rule of the translation to the left 5 and down 7 will be:
(x, y) → (x-5, y+7)
C(-1, -4) → (-1-5, -4+7) = C'(-6, 3)

Use the distributive property to expand 0.05(50 + 40).
Answers
Answer:
4.5
Step-by-step explanation:
Here's what I found on google about distributive property:
To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Now for the math-
distribute the numbers- 0.05(50)+0.05(40)
solve- 0.05*50= 2.5
0.05*40= 2
2.5+2= 4.5

Amount of money saved 25 35 45 55 65 75 85
Step-by-step explanation:
Explanation: On week 1 you have the $25 you already saved plus the $10 for that week, so $35.
For every week after that add $10 to the money saved for the additional $10 saved that week.
On the 8th week the total amount of money saved is 95+10, or $105.

[tex]2 \frac{2}{13} + \frac{15}{13} =[/tex] [tex]2 \frac{2}{13} + 1 \frac{2}{13} = 3 \frac{4}{13}[/tex]
Answer: The answer is option 2. 3 4/13
Step-by-step explanation:
2 2/13 + 15/13 = 2 17/13
17 fits into 13 one time and you're left with 4/13 as a remainder.
Since 17 was able to fit into 13 at least once, you get another whole number making your already existing whole number of 2 into 3.
Thus your answer is 3 4/13. I hope this was a helpful explanation! :)
Determine whether the relationship being represented is Linear, Exponential or Neither : LaTeX: f\left(x\right)=\frac{1}{3}x+2f ( x ) = 1 3 x + 2 Group of answer choices Linear Exponential Neither
Answers
Answer:
Linear
Step-by-step explanation:
Given
[tex]f\left(x\right)=\frac{1}{3}x+2[/tex]
Required
Determine the relationship
From the group of options, Linear answers the question.
This is so because, a linear equation is of the form: [tex]f(x) = ax + b[/tex]
By comparing [tex]f(x) = ax + b[/tex] with [tex]f\left(x\right)=\frac{1}{3}x+2[/tex], we have that:
[tex]a = \frac{1}{3}[/tex]
[tex]b = 2[/tex]
and
[tex]f(x) = f(x)[/tex]
Hence, the equation is a linear equation
State the independent variable and the dependent variable in the linear relationship. Then find the rate of change for the situation. The cost of dinner is $42 for three people and $98 for seven people
Answers
Answer:
144
Step-by-step explanation:
The independent variable in the linear relationship is the number of people.
The dependent variable in the linear relationship is the cost of the dinner.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Cost of dinner for 3 people = $42
Cost of dinner for 7 people = $98
The cost of dinner for one person = $14
Now,
The linear function for this relationship.
f(x) = 14x
Where x is the number of people and f(x) is the cost of the dinner.
Now,
The number of people is the independent variable.
The cost of dinner is the dependent variable.
Thus,
Independent variable = Number of people/
Dependent variable = Cost of the dinner.
