Answer:
A closed circle on the number line means that the number is a possible solution.
Step-by-step explanation:
An open circle on the number line means that the number is not a possible solution.
A closed circle on the number line means that the number is a possible solution. Unfalsifiable arguments are referred to as closed-circle arguments.
What is meant by closed circle?Unfalsifiable arguments are referred to as closed-circle arguments. The supporters of Karl Popper, for instance, point to psychoanalytic theory as an illustration of an ideology rather than a science.
A circle is a spherical shape without boundaries or edges. A circle is a closed, curved object with two dimensions in geometry.
A closed and an open circle. An inequality is said to have less than () or more than (>) when it has an open circle. If the circle is closed, the inequality has a less than or equal to () or greater than or equal to () sign.
Therefore , A closed circle on the number line means that the number is a possible solution.

what is 3y mean in a math problem
Answer:
3y means 3 * y
Step-by-step explanation:
I think it is written as 3y instead of 3*y or 3 x y because, 3*y is a bit too cluttered, and 3xy or 3 x y means (Three times X times Y) because X is its own variable.
In other words, 3y means 3 times y
In any of the mathematical problem, the value of 3y will be 3 × y.
What is a mathematical problem?
A mathematical problem is any issue that may be modeled, examined, and potentially resolved using mathematical techniques. This can be a practical issue, like calculating the orbits of the solar system's planets, or a more theoretical issue, like Hilbert's conundrums.
In other cases, such as Russell's Paradox, it can also represent an issue with the very nature of mathematics. Building a mathematical model of the issue is typically the first step in applying mathematics to a real-world situation.
In order to translate the original problem into a mathematical one, it is necessary to abstract from the specifics of the problem, and the modeler must be careful not to lose key features in the process.
Therefore, in any of the mathematical problem, the value of 3y will be 3 × y.

Answer:
It should take about 54 minutes!
Step-by-step explanation:
30% / 18 = 100% / ?
30 x ? = 100
30 x 3(roughly) = 100
So, 18 x 3 = 54.

Answer: x = 7
Step-by-step explanation:
Put both angles in an equation that equals 90 degrees
5x + 55 = 90
subtract 55 from both sides
5x = 35
divide by 5
x = 7
Now check if its true.
5(7) + 55 = 90
35 + 55 = 90

A solution to the equation x^3 + 2x - 25 = 0 lies between 2 and 3. Find this solution correct to 1 decimal place
:))
The solution to the equation x^3 + 2x - 25 = 0, correct to 1 decimal place, is approximately x = 2.7.
To find the solution to the equation x^3 + 2x - 25 = 0, we can use numerical methods such as the bisection method or Newton's method. Let's use the bisection method to find the solution between 2 and 3.
Evaluate the equation at the lower and upper bounds:
f(2) = (2)^3 + 2(2) - 25 = 8 + 4 - 25 = -13
f(3) = (3)^3 + 2(3) - 25 = 27 + 6 - 25 = 8
Check if the function changes sign between the lower and upper bounds:
Since f(2) is negative and f(3) is positive, we can conclude that there is at least one root between 2 and 3.
Perform iterations of the bisection method:
Divide the interval [2, 3] into two equal halves:
Lower bound: a = 2, Upper bound: b = 3
Midpoint: c = (a + b) / 2 = (2 + 3) / 2 = 2.5
Evaluate the function at the midpoint:
f(c) = (2.5)^3 + 2(2.5) - 25 = 15.625 + 5 - 25 = -4.375
Check the sign of f(c):
Since f(c) is negative, we update the lower bound to c, as the solution lies between the lower bound and c.
Repeat the steps with the new interval [2.5, 3]:
Lower bound: a = 2.5, Upper bound: b = 3
Midpoint: c = (a + b) / 2 = (2.5 + 3) / 2 = 2.75
Evaluate the function at the new midpoint:
f(c) = (2.75)^3 + 2(2.75) - 25 = 20.796875 + 5.5 - 25 = 1.296875
Check the sign of f(c):
Since f(c) is positive, we update the upper bound to c, as the solution lies between c and the upper bound.
Repeat the steps until the desired level of precision is achieved:
Continue dividing the interval and evaluating the function at each midpoint until the interval becomes sufficiently small.
Continue the bisection method iterations:
Repeat the steps until the interval is small enough:
[2.5, 2.75]
[2.625, 2.75]
[2.6875, 2.75]
[2.71875, 2.75]
[2.734375, 2.75]
[2.734375, 2.7421875]
The final interval [2.734375, 2.7421875] contains the solution.
Therefore, the solution to the equation x^3 + 2x - 25 = 0, correct to 1 decimal place, is approximately x = 2.7.
