The length of the sides of cube will be;
⇒ 2 cm
What is mean by Cube?A cube is the solid shape or three-dimensional shape. A convex polyhedron which is bounded by six squared faces with eight vertices and twelve edges is called cuboid.
Given that;
The surface area of a cube = 24 cm².
We know that;
The surface area of a cube with side 'a' is,
⇒ S.A = 6a²
Here, The surface area of a cube = 24 cm²
Hence, We get;
⇒ 24 = 6a²
⇒ 24/6 = a²
⇒ a² = 4
⇒ a = √4
⇒ a = 2 cm
Thus, The side of cube = 2 cm

What is a proportional relationship?In order to have a proportional relationship and equivalent ratios, the variables x and y must have the same constant of proportionality.
Next, we would determine the constant of proportionality (k) as follows:
Constant of proportionality (k) = y/x
Constant of proportionality (k) = 4/8
Constant of proportionality (k) = 0.5.
When hours y = 6, the number of treasure chests x is given by:

What is the x-intercept of the graph of y x2 − 4x 4?
The x-intercept for the graph of y is found to be at x = 2.
Define the term x-intercept?The points where such a line crosses an axis are known as the x-intercept and the y-intercept, respectively.The graph's intersection with the x-axis is known as the x-intercept.Therefore, the y coordinate would be zero at that time.The quadratic equation given is
y = x² - 4x + 4
Put y = 0
0 = x² - 4x + 4
It becomes perfect square for (x - 2).
It can be written as;
(x - 2)² = 0
Take square root on the both sides
x - 2 = 0
x = 2
Thus, the x-intercept for the graph of y is found to be at x = 2.

What is the value FG?
FG is not a defined term, so there is no way to determine its value.
FG is not a defined term, so there is no way to determine its value. This means that we cannot assign a numerical or other value to it. In order to determine the value of FG, we would first need to identify the context in which it is being used, as different contexts may assign different meanings to the same term. Once the context has been established, we can then look up the definition of FG in order to understand what it means in that particular context, and then assign a value to it accordingly. For example, if FG stands for "Frequency Generator" in a physics context, then it would likely have a numerical value associated with it.

What are the intervals of 5?
The set of numbers x such that 0 ≤ x ≤ 5 is an interval containing 0, 5, and all numbers between 0 and 5.
Interval notation is a way of representing intervals on the number line. That is, how to write a subset of the real number line. Intervals include numbers between two specific numbers.
In mathematics, a (real) interval is a set of real numbers containing all real numbers between any two numbers in the set. For example, the set of numbers x such that 0 ≤ x ≤ 1 is an interval containing 0, 1, and all numbers in between. Other examples of intervals are the set of numbers with 0 < x < 1, the set of all real numbers, the set of non-negative real numbers, the set of positive real numbers, the empty set, and any Singleton (a set of one element).
Real intervals play an important role in integral theory. This is because real intervals are the simplest set whose "length" (or "scale" or "magnitude") is easy to define. The notion of measure can be extended to more complex sets of real numbers, leading to the Boral measure and finally the Lebesgue measure.
Intervals are central to interval arithmetic, a general numerical technique that automatically provides guaranteed bounds for any mathematical expression, even in the presence of uncertainties, mathematical approximations, and arithmetic rounding.

What is the x-intercept of the graph of y x2 4x 4?
The x-intercept of the graph of y = x² - 4x + 4 is x = 2.
By looking at the equation, we may determine the y-intercept when the equation is expressed in the slope-intercept form (y=mx+b). The y-intercept is the value of b. This is due to the fact that the y-intercept occurs when the x value is 0. Y = B when x = 0, since mx = 0 at this point.
We set y = 0 and solve the equation for x to determine the x-intercept. This is due to the fact that the line crosses the x-axis at y=0. If an equation is not in the form y = mx + b, we can still solve for the intercepts by substituting 0 where necessary and then solving for the final variable.
The formula for the x-intercept is y = 0: The x-intercept(s) can be determined by factoring or by employing the quadratic formula because ax2 + bx + c=0.

What number would you need to multiply the first equation by to eliminate the y variable when solving the system of equations by elimination?
We would need to multiply the first equation by -4 to eliminate the y variable when solving the system of equations by elimination.
The first equation is: 3x + 4y = 5
To eliminate the y variable when solving the system of equations by elimination, we need to multiply the first equation by -4. This is because when two equations are multiplied by the same number, any terms that have the same variable will be eliminated when the equations are added together.
Formula:
3x + 4y = 5
-4(3x + 4y = 5)

Mia brought n shirts that were originally priced at $26.99 each shirt was on sale for $5.99 off the original price that she bought them which expression can be used to find the total sale price of n shirts
The total sale price of n shirts can be found using the following expression:
total sale price = n * (26.99 - 5.99)
This expression first calculates the sale price of a single shirt by subtracting the discount from the original price, and then multiplies that value by the number of shirts to get the total sale price.
For example, if Mia bought 3 shirts, the total sale price would be 3 * (26.99 - 5.99) = 3 * 21 = 63.

What is the probability that the sum of the 2 dice rolls will not be greater than 8?
The probability that the sum of the 2 dice rolls will not be greater than 8 are 8 : 13.
How to evaluate for the probabilityWhen the probability of an event occurring is know, it is easy to calculate the probability that the event does not occur. Hence, If P(A) is the probability of event A, then 1 - P(A) is the probability that the event does not occur.
the probability that the sum of the 2 dice rolls being greater than 8 are expressed in the ratio 5:13 and expressed in fraction as 5/13
then;
probability that the sum of the 2 dice rolls will not be greater than 8 = 1 - 5/13
probability that the sum of the 2 dice rolls will not be greater than 8 = (13 - 5)/13
probability that the sum of the 2 dice rolls will not be greater than 8 = 8/13

Selena has 9 homemade bracelets for $12 each then 14 bracelets for $8 each. How much did she make in sales?
Answer:

Step-by-step explanation:
first let's make the $12 bracelets as Type1 and the $8 bracelets as Type2,
then we calculate the amount she made by selling each type.
Eq.1 : No. of Type1 bracelets Selena made = 9
Amount she sold them for = $12
Amount she made by selling them = 9*12
= $108
Eq.2 : No. of Type2 bracelets Selena made = 14
Amount she sold them for = $8
Amount she made by selling them = 14*8
= $112
Now we calculate the Total Amount she made
we add both of the amounts
$108 + $112

I have x N50 note and y N100 note. There are eight note altogether and their total value i N550. How many of each note do I have?
So I have 5 and 3 notes each
You need to use simultaneous equations to solve this problem since there are 2 variables.
50x + 100y = 550 (value of the notes x the number of each note)
x + y = 8 (the number of each note added).
Multiply the second equation by 50 so that it the x variables are the same in both equations. Thus, 50x + 50y = 400.
Subtract 50x + 50y = 400 from 50x + 100y = 550.
The subtraction results in 50y = 150.
Divide by 50. y = 3, so x must equal 5.
So I have 5 and 3 notes each
