B) y = 5x
C) y = 6x
D) y = 1/5x
Answers
The solution is, choice B) \(y=5x\) represent a proportional relationship.
What is proportional relationship?A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form \(y\div x = k\) or \(y = kx\)
here, we have,
we know that,
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
so, we get,
choice A) \(y=30x\)
Is a linear equation that passes through the origin
therefore,
The case A) represent a proportional relationship
choice B) \(y=5x\)
Is a linear equation that passes through the origin
therefore
The case B) represent a proportional relationship
choice C) \(y =6x\)
Is a linear equation but not passes through the origin
therefore
The case C) does not represent a proportional relationship
choice D) \(y = \dfrac{1}{5}x\)
Is a linear equation but not passes through the origin
therefore
The choice D) does not represent a proportional relationship
Hence, The solution is, choice B) \(y=5x\) represent a proportional relationship.

Explains why anyone in the classroom can hear that loud teacher...
Step-by-step explanation:
Let us first differentiate reflection, refraction, and diffraction.
Reflection occurs when the waves bounce off the medium or the boundary that is in the way of the wave. Some part of the wave would bounce off, and the others would go through the medium through a process called transmission.
When light for example hits a smooth surface at a certain angle, the light would bounce off, creating an equal going the other way.
Best example of this behavior of light would be the mirror.
Refraction on the other hand, bends the waves as they go through one medium to another medium, or change their direction. The amount or degree of the bend would depend on the medium they go through. If the mediums are different, it would substantially change the wave's path. The reason for this is because the medium changes the speed of the waves that go through them, depending on the material they are made up of.
A classic example of this would be the straw in a glass of water.
Diffraction occurs when the waves go through an opening of the medium or barrier. If the opening is smaller than the wave that passes through it, it would spread out wider, coming out of the opening, but if it is bigger, then the spread would decrease.
In x-ray crystallography, they use this by letting x-rays pass through the spaces in between the crystals.

What is the largest rational number which satisfies the inequality 2x≤ 7.
Step by step answer
Answers
Answer:
\(x\leq \frac{7}{2}\)
Step-by-step explanation:
To get this answer, you would need to divide 2 from both sides.
--
Since 2 can't go into 7 respectfully, it would remain 7 over 2 unless converted into a decimal which is 3.5 [Which would make the answer x ≤ 3.5]

Hence, the answer would be 7/2 as it's final answer

Answers
Answer:
In lowest terms, there is a 1/3 probability of Jason pulling out a baseball card.
Step-by-step explanation:
There are a total of 6 cards. 4/6 of them are football and wrestling which results in 2 baseball cards. So the probability is 2/6 but since the question wants it in lowest terms, you would have to simplfy 2/6. Divide the top by 2 and the bottom by 2 which gets you 1/3.

NEED HELP ASAP NO FALSE ANSWERES. Part B: Scarlett made a profit of $250.00 with her mobile car wash company. She charged $75.00 per car wash and received $35.00 in tips, but also had to pay $5.00 in
cleaning supplies per car wash. Write an equation to represent this situation
Answers
Answer:
y = 70x + 35
Step-by-step explanation:
$75 - $5 = $70 (this is the amount charged minus the amount needed to get the job done per car wash)
the +35 is the tips extra/ constant that will be added after the jobs are done.
x is the amount of car washes done
y would be the profit received.
thus y = 70x + 35 (profit = value of car wash * number of cars washed + tips)
Answer:
Step-by-step explanation:
Profit = Income less outgo
= (car wash income + tips) - (supplies)
$250 = ($75n + $35) - ($5n), or
$215 = $70n (where n represents the number of cars washed)
This comes out to n = $215/$70, or approximately 3 car washes.

If 1 bottle weighs 3/5 pounds
the 6 bottles will weigh 6 x 3/5
= 18/5

6:x
since the ratios are direct we can cross multiply
18/5 = 1x
