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.
Hope this helps :)

Carlos and Ethan noticed that both proportional relationships and linear functions form a straight line when graphed. Carlos claims that all linear functions are also proportional relationships. Ethan disagreed and tells Carlos that he has it backwards, that all proportional relationships are linear functions. Which statement accurately compares their observations?
A) Carlos is correct because all linear functions go through the origin.
B) Ethan is correct because all proportional relationships form a straight line and go through the origin and linear functions are linear, but they don’t all go through the origin so they are not always proportional.
C) Carlos is incorrect because no proportional relationships are linear.
D) Both Carlos and Ethan are incorrect, no proportional relationships are nonlinear.
Answer:
B. Ethan is correct because all proportional relationships form a straight line and go through the origin and linear functions are linear, but they don’t all go through the origin so they are not always proportional.
Step-by-step explanation:
So a proportional relationship is just a special kind of linear relationship, i.e., all proportional relationships are linear relationships (although not all linear relationships are proportional).

Sam aims to run a total of 18 miles in 5 weeks. He ran 2 ¾ miles in the first week, 3 ½ miles in the second week, 5 ⅓ miles in week three, and 2 ⅘ miles in week four. How many more miles would he need to complete to reach his target?
Answer:
[tex]\frac{37}{60}[/tex] or 0.62 of a mile that he will need to complete to reach his target.
Step-by-step explanation:
[tex]2 \frac{3}{4} + 3 \frac{1}{2} + 5 \frac{1}{3} + 2 \frac{4}{5} = \frac{863}{60} \\18-\frac{863}{60} = \frac{37}{60}/ 0.62[/tex]

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

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.

A penguin walks 15 feet in 9 seconds.
at this speed:
b. How long does it take the penguin to walk 20 feet?
Please tell me how you got that answer too.
Answer:
12 seconds.
Step-by-step explanation:
If you put it like 15/9 = 20/x, then cross multiply and divide you do 9 times 20 you get 180, then you divide 180 by 15 and you get 12. Hope this helps!

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
