Which linear equation shows a proportional relationship?
y equals two thirds times x
y equals negative 3 times x minus one seventh
y equals three fourths times x minus 5
y equals 3 times x plus 7
The linear equation that shows a proportional relationship is y equals two thirds times x.
A proportional relationship is a relationship between two variables in which one variable is a constant multiple of the other. In other words, if y is directly proportional to x, then y = kx for some constant k. This can also be written as y/x = k, where k is the constant of proportionality.
The linear equation that shows a proportional relationship is y = 2/3x.
It shows a direct relationship because the coefficient of x (2/3) is constant, and there is no constant term (y-intercept) which breaks the proportionality.
The other equations do not show a proportional relationship because they have a coefficient that varies with x or a constant term.

Mr. Klimek made his wife a rectangular vegetable garden. The width is 5 3/4 ft, and the length is 9 4/5 ft. Mr. Klimek calculated his garden to be 15 11/20 square feet. Is Mr. Klimek correct with his calculations? If he is, what did he do to find his answer. If he is incorrect, what did he specifically do wrong, what is the correct answer? Show and Explain.
Answer:
He is wrong. The right answer is 56.35. Or 56 7/20
Step-by-step explanation:
So lets go over what we know.
The width is 5 3/4ft.
The length is 9 4/5 ft.
The square feet is l*w, otherwise known as area.
So in this, we multiply 5 3/4 by 9 4/5.
Before we multiply however, lets put this into decimal form. Its easier to think of it this way.
3/4, or 3 divided by 4, is 0.75 So 5 3/4 is actually 5.75
4/5, or 4 divided by 5, is 0.80. So 9 4/5 is actually 9.8
Now lets multiply:
5.75*9.8
This might seem a bit confusing, but here is a step by step way of how I multiplied:
5*9 is 45. 5 times 8 is 40. Move the decimal since we used 8 instead of .8 its now:
45 and 4.0
Which is 49.
Now lets multiply 9.8 by the 0.75
3/4ths of 9 is 6.75. 3/4 of 8 is 6. Again, move over the decimal since we used 8 instead of .8 its now:
6.75 and .6
This is 7.35
Add that to 49:
56.35
So this is your answer.
Now, this is not what Mr.Klimek got.
So he is wrong.
The real answer is 56.35
To find the fractional form of this, we can take the decimal 35 and put it over 100:
35/100
Then simplfy. In this case 5 goes into both numbers. So:
7/20
So we have 56 7/20.
Now, the final question, what did Mr.Klimek do wrong?
Well, he added his length and width, instead of multiplying.
We already know what our two numbers equal: 9.8 and 5.75.
Lets add these:
9 plus 5 is 14. 0.8+0.75 is 1.55.
14+1.55=15.55
Using the method of transfering fractions I spoke of above:
55/100
5 goes into both numbers:
11/20
So adding the lenght and width, we got 15 11/20. This is what Mr.Klimek did.
So to sum up each answer:
The answer is 56.35 or 56 7/20Mr.Klimek is incorrect.Mr.Klimek added the length and Width, instead of multiplying.Hope this helps! :D

The radius $r$ of a circle inscribed within three mutually externally tangent circles of radii $a$, $b$ and $c$ is given by \[\frac{1}{r}
The formula yields the radius $r$ of a circle that is inscribed within three circles with radii $a$, $b$, and $c$ that are mutually external tangents.
[tex][\frac{1}{r} = \frac{1}{a} + \frac{1}{b} + \frac{1}{c}][/tex]
The radius of the inscribed circle is related to the radii of the three mutually externally tangent circles using a method known as the radical centre formula. According to this equation, the reciprocals of the radii of the three externally tangent circles add up to the radius of the circle that is inscribed.
The power of point theorem states that the product of the distance between the point and the three points of tangency is equal to the product of the distance between the point and the centres of the circles. This formula is based on the fact that the circles are mutually externally tangent and their centres are collinear. It is crucial to note that the formula can only be used if the circles are mutually externally tangent; otherwise, it is invalid.

Are parallel algorithms always faster than sequential algorithms?
Answer:
Step-by-step explanation:
Parallel algorithms are not always faster than sequential algorithms. In general, the speed of an algorithm depends on a variety of factors, including the complexity of the algorithm, the hardware it is running on, and the specific problem it is trying to solve.
There are some cases where a parallel algorithm can be faster than a sequential algorithm. For example, if an algorithm can be easily divided into smaller subproblems that can be solved independently and then combined to get the final result, it may be possible to speed up the overall computation by using a parallel algorithm to solve the subproblems in parallel. This can be particularly effective if the subproblems are large and can be solved using multiple processor cores or distributed across multiple computers.
However, there are also cases where a sequential algorithm may be faster than a parallel algorithm. For example, if the problem is relatively small and can be solved efficiently using a single processor, it may not be worth the overhead of dividing the problem into smaller subproblems and coordinating their solution in parallel. In addition, some algorithms may be more difficult to parallelize, or may not lend themselves well to a parallel solution, in which case a sequential algorithm may be a better choice.
Overall, it is important to carefully consider the specific problem and available hardware when deciding whether to use a parallel or sequential algorithm.
Solve for x. Round your answer to the nearest tenth if necessary. NO SCAMS OR LINKS PLEASE!!!!!! ANSWER IS NOT 14.1
Answer:
[tex]\boxed {\boxed {\sf x\approx 7.3}}[/tex]
Step-by-step explanation:
The triangle has a small square in the corner representing a 90 degree angle. This is a right triangle so we can use the Pythagorean Theorem to solve for the sides.
[tex]a^2+b^2=c^2[/tex]
In this equation, a and b are the legs and c is the hypotenuse.
x and 8.5 are the legs because they make up the right angle. 11.2 is the hypotenuse because it is opposite the right angle.
a= xb=8.5 c=11.2Substitute the values into the formula.
[tex]x^2+(8.5)^2=(11.2)^2[/tex]
Solve the exponents.
(8.5)²= 8.5*8.5= 72.25 (11.2)²= 11.2*11.2= 125.44[tex]x^2+72.25 =125.44[/tex]
Solve for x by isolating the variable. 72.25 is being added, so we subtract 72.25 from both sides because subtraction is the inverse operation of addition.
[tex]x^2+72.25-72.25 = 125.44-72.25[/tex]
[tex]x^2=125.44-72.25[/tex]
[tex]x^2=53.19[/tex]
x is being squared, so we take the square root of both sides.
[tex]\sqrt{x^2}=\sqrt {53.19}[/tex]
[tex]x=\sqrt{53.19[/tex]
[tex]x=7.29314746869[/tex]
Round to the nearest tenth. The 9 in the hundredth place tells us to round the 2 up to a 3.

Wastewater is filling barrels at the rate of 13 quarts per hour. The recycling facility picks up 96 full barrels on each trip, and each barrel holds 30 quarts of wastewater. How many days are between each pickup
If the recycling facility picks up 96 full barrels on each trip then there is 9 days gap between each pickup.
What is the recycling facility picks up?Recycling is the practice of reusing materials in existing products to create new ones. This can be accomplished in expected ways—such as using recycled paper as packaging material—or unexpected ways—such as using recycled glass to make artificial turf. Recycling helps to conserve limited resources, and—its proponents argue—it has other environmental benefits as well.
Since the recycling facility picks up 96 barrels on each trip
and each barrel contains 30 quarts of effluent.
Thus, the total volume of wastewater is 30 x 96, or 2880 quarts.
Each barrel is filled at a rate of 13 quarts per hour.
So 2880 quarts filled in hours.
We can now change 221.54 hours to days.
= 9.23 days
There are so 9 days in between pickups.
