According to the information, we can infer that the average speed of the train could not have been greater than 145 km/h.
How to determine if the average speed of the train could have been greater than 145 km/h?To determine if the average speed of the train could have been greater than 145 km/h, we need to calculate the maximum possible average speed based on the given information.
The train traveled along a track that is 290 km long, and it took 120 minutes (correct to the nearest 5 minutes). To find the maximum possible average speed, we assume the train traveled the shortest possible distance and took the longest possible time.
Taking the track measurement into account (correct to the nearest 10 km), the track length could be as short as 285 km (290 km - 5 km) or as long as 295 km (290 km + 5 km).
Considering the time measurement (correct to the nearest 5 minutes), the time taken could be as short as 115 minutes (120 minutes - 5 minutes) or as long as 125 minutes (120 minutes + 5 minutes).
To find the maximum possible average speed, we divide the maximum distance (295 km) by the minimum time (115 minutes):
Max average speed = 295 km / 115 minutes ≈ 2.565 km/minute ≈ 154.04 km/hAccording to the above, the maximum possible average speed is approximately 154.04 km/h. So, it is not possible for the average speed of the train to have been greater than 145 km/h.

Quick algebra 1 question for 50 points!
Only answer if you know the answer, quick shout-out to Yeony2022, tysm for the help!
Answer:
d: y=5x
Step-by-step explanation:
Since we know a few points: (2,10), (3,15), (4,20), we can use two of them to first find the slope. The equation for the slope is (Increase in y)/(increase in x).
1. Slope between (2,10) and (3,15) is 5/1 which is 5. So the slope will be 5.
2. With the slope, we know that our equation will be: y=5x+b. To find b, we can replace x and y with another point. 20 = 5(4)+b. --> 20 = 20 +b. Now we know that b equals 0.
Our final equation will be y = 5x.
RECHECKING!
I'll recheck whether my answer is right or not using Desmos (A online graphing calculator).
I added an image down below, and I drew the points in blue. This shows that since the graph crosses all three points, it is correct.
WHY y=1/5x IS NOT CORRECT (based on your comments)
If you look at the points, the relationship between x and y is not 1/5. If you multiply something from x, it should become 10.
--> 2 times __ = 10
--> 3 times __ = 15
--> 4 times __ = 20
And clearly, __ will be 5. If it becomes 1/5, we won't get the right number of y.
This is why y=1/5 is not correct.
Hope this helps!

In my town’s subway, the Circle Line travels clockwise around a circular track with a radius of 5
kilometers. I start at the westernmost point of the Circle Line and travel 3
4
of the way around the
track. Then I transfer to the Town Line, which takes me 7 kilometers south. When I get off the
subway, how many kilometers away am I from my original starting position?
If the Circle Line travels clockwise around a circular track with a radius of 5 kilometers, you are approximately 24.22 kilometers away from your original starting position.
To determine how many kilometers away you are from your original starting position, we can use geometry and the Pythagorean theorem.
First, we need to find the distance you traveled on the Circle Line. Since you traveled 3/4 of the way around the circular track, we can find the distance traveled by using the formula for the circumference of a circle:
C = 2πr = 2π(5 km) ≈ 31.42 km
So, you traveled 3/4 of the circumference, or:
d = (3/4)C = (3/4)(31.42 km) ≈ 23.56 km
Next, we need to find the distance you traveled on the Town Line, which is 7 kilometers south.
Now, we can use the Pythagorean theorem to find the distance between your current location and your original starting position. Since you traveled on a circular track, your original starting position is the center of the circle, and your current location is the endpoint of the two segments you traveled.
The distance between them is the hypotenuse of a right triangle with legs of 5 km (the radius of the circle) and 23.56 km (the distance you traveled on the Circle Line). Using the Pythagorean theorem, we get:
d = √(5^2 + 23.56^2) ≈ 24.22 km

A box is 10in. high, 20in. long, and 12in. wide. What is the longest poster you could fit in the box? Use pencil and paper. Explain why you can only fit one maximum-length poster in the box but you can fit multiple 22-in. posters in the same box.
The longest poster that can fit in the box must have dimensions of 10 inches (height) by 20 inches (length) by 12 inches (width).
To find the longest poster that can fit in the box, we need to determine the longest dimension of the box itself. Since the box is 10 inches high, the longest poster that can fit in the box must have a height of no more than 10 inches.
Now, we need to consider the other two dimensions of the box. The box is 20 inches long and 12 inches wide, so the longest poster that can fit in the box must have a length of no more than 20 inches and a width of no more than 12 inches.
As for why we can only fit one maximum-length poster in the box but we can fit multiple 22-inch posters in the same box, it's because the length and width of the box are larger than the length and width of the 22-inch poster.

Write each polynomial in standard form. Identify the leading coefficient.
4x + 2x5 – 6x3 + 2
Given:
The polynomial is
\(4x+2x^5-6x^3+2\)
To find:
The standard form of the polynomial and leading coefficient.
Solution:
In standard form of a polynomial, we arrange the terms in descending order of their degrees.
Leading coefficient is the constant value before the variable with highest power.
Let the given polynomial be p(x).
\(p(x)=4x+2x^5-6x^3+2\)
The standard form of the polynomial is
\(p(x)=2x^5-6x^3+4x+2\)
The highest power of x is 5 and 2 is before \(x^5\). The leading coefficient is 2.
Therefore, the standard form of the polynomial is \(2x^5-6x^3+4x+2\) and the leading coefficient is 2.
given a 14 percent return how long would it take to triple your
investment, solve using time value formula
It would take approximately 9.4 years to triple your investment with a 14% return, assuming compound interest.
To determine how long it would take to triple your investment with a 14% return, we can use the compound interest formula
Future Value = Present Value × (1 + Interest Rate)ⁿ
In this case, the Future Value is three times the Present Value, the Interest Rate is 14% (or 0.14), and we want to solve for Time.
Let's denote the Present Value as P and the Time as n:
3P = P × (1 + 0.14)ⁿ
Now, we can simplify the equation:
3 = (1.14)ⁿ
To solve for n, we need to take the logarithm of both sides of the equation. Let's use the natural logarithm (ln) for this calculation:
ln(3) = ln((1.14)ⁿ)
Using the logarithmic property, we can bring down the exponent:
ln(3) = n × ln(1.14)
Now, we can solve for t by dividing both sides of the equation by ln(1.14):
n = ln(3) / ln(1.14)
we can find the value of t:
n ≈ 9.4
Therefore, it would take approximately 9.4 years to triple your investment with a 14% return, assuming compound interest.

What is the smallest number, which is neither prime nor a square and that has no prime factor smaller than 100?
Answer:
10403.
Step-by-step explanation:
To find the smallest number that isn't prime and doesn't any factors smaller than 100, we need to multiply the 2 smallest prime numbers greater than 100. The smallest prime number greater than 100 is 101, but we cannot multiply 101 by itself, as the number would become a square. Because of this, we need to multiply 101 by the next smallest prime number, which is 103.
After multiplying 101 by 103, we get 10403.
To check our answer, we can verify each point.
10403 is not prime, as it has 2 factors, 101 and 103.
10403 is not square, as the square root of 10403 is 101.9951.
10403 has 2 factors 101 and 103, both of which are greater than 100.

Find the percent increase in volume when 1 foot is added to each dimension of the prism. Round your answer to the nearest tenth of a percent. Percent increase ≈ %
Answer:
The percentage increase in volume of the prism is impossible to find. This is because the current dimension or the diagram from which the dimension of the prism could be determined is not given.
However I will explain the methods to follow in finding this percentage increase, assuming that the current dimension of the prism is given.
Step-by-step explanation:
Assuming the volume the of prism is x ft³. After adding 1 ft to each dimension, the volume becomes y ft³.
The percentage increase = (y/x) × 100
= z%
That is,
Percentage increase = [(New volume) ÷ (Old volume)] × 100
The resulting value, z% is the percentage increase.
