find the edge length of a cube whose volume is 1.728cubic cm is the edge length a rational number
The edge lengths of a cube that has a 1.728 cm³ volume is 1.2 cm
What is the volume of a cube?The volume of a cube is the given by the length of one edge raised to the power of 3
The volume of a cube, V = Length, L × Width, W × Height, H
Given that the lengths of the edges of a cube are equal, we have!
Length, L = Width, W = Height, H
Which gives;
The volume of a cube, V = L × L × L = L³
Therefore, for the given cube, we have;
L³ = 1.728 cm³
1.728 = 1728/1000
(a + b)³ = a³ + 3•a²•b + 3•a•b² + b³
Taking a = 10, and b = 3, we have;
(10 + 2)³ = 10³ + 3×10²×2 + 3×10×2² + 2³ = 1728
Therefore;
1728/1000 = (10 + 2)³/10³ = 12³/10³
Which gives;
L³ = 12³/10³
[tex] \displaystyle {L = \sqrt[3]{ \frac{{12}^{3} }{ {10}^{3} } } = 1.2}[/tex]
The edge lengths of the cube, L = 1.2 cm

five fair dice were tossed, and the sum of the resulting tosses was recorded. this process was repeated 10,000 times using a computer simulation. the number of times the sum of the five tosses equaled 26 was 53. what is the estimated probability that the sum of the five dice will be 26? (give the answer to four decimal places.)
The estimated probability that the sum of five dice will be 26 is 0.0053
What is meant by Estimated Probability?Estimated Probability: Estimated probability is an approximation, or estimate, of theoretical probability. The larger the number of trials, the more accurate we expect this approximation to be. If E consists of a single outcome s, we refer to P(E) as the probability of the outcome s, and write P(s) for P(E)
N = Number of Repeated Process = 10,000
n = Number of times the sum of the five tosses equaled 26 = 53
The estimated probability that the sum of the five dice will be 26 = n/N
Where n = 53
And N = 10,000
Using the above formula, we have the following:-
n/N becomes
n/N = 53/10,000
n/N = 0.0053
Hence, the estimated probability that the sum of five dice will be 26 is 0.0053

distance (in miles)
Driving time(in minutes)
As per the linear function, the destination after 57 minutes of driving is 1055 miles.
Linear function:
The linear equation is defined as an algebraic equation of the form
y = mx + b.
involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.
Given,
Trey is driving to Philadelphia. Suppose that the distance to his destination (in miles) is a linear function of his total driving time (in minutes).
Trey has 49 miles to his destination after 37 minutes of driving, and he has 37.8 miles to his destination after 51 minutes of driving.
Here we need to find his destination after 57 minutes of driving.
In this one, first we have to find the linear equation for the situation.
For that, we need the slope and the intercept.
So, here we consider the distance as y axis and the corresponding time as x axis. then we get the points as,
(x1. y1) => (37, 49)
(x2, y2) => (51,37.8)
Then the slope of the line is calculated as,
m = (37.8 - 49) / (51 - 37)
m = -11.2/14
Now, the intercept is calculated using the point (37,49) and the slope m = -11.2/14 is,
49 = -11.2/14(37) + b
686 = -414.4 + b
b = 1100.4
So, the linear equation of the function is
y = -11.2/14x + 1100.4
Here we need to find the distance when the time is 57 minutes,
For that, we have to apply the value of x as 57, to get the value of y,
Therefore,
y = -11.2/14 (57) + 1100.4
y = -45.6 + 1100.4
y = 1055
Therefore, the destination after 57 minutes of driving is 1055 miles.

Safara wants to rent a bicycle the graph shows the cost for renting a bicycle for different lengths of time. What is the slope of the line?
The slope of the line will be equal to 30.
Slope of a line may be defined as the steepness of a curve. Slope of line can be positive, negative or zero. Slope of a line is used to determine the equation of the line which is given as y = mx + b where m is the slope, b is y intercept and x and y are independent and dependent variables respectively. The slope of a line on points (x₁, y₁) and (x₂, y₂) is given by the formula, m = y₂ - y₁/x₂ - x₁.
According to the question the value of points is (x₁, y₁) = (0, 0) and (x₂, y₂) = (2, 60).
Now, the slope can be calculated as
m = (60 - 0)/(2 - 0)
=> m = 60/2
=> m = 30 which is the required slope.

Step-by-step explanation:
35+35= 70 right?
So then would have to subtract the 70 from 180 because that is total length of an angle to get 110 degrees
110 degrees
I might be wrong, because it might be different with triangles
Answer:
U = 110
Step-by-step explanation:
The formula for finding missing angle is.
a + b + c = 180 or in this case S + U + T = 180.
You already have the measurement of two angles so plug those in.
35 + U + 35 = 180
Now all you have to do is simplify and solve it.
35 + 35 + U = 180
70 + U = 180 you simplify by adding together 35.
U = 110 to cancel out 70 and isolate U you subtract 70 to both sides.

Properties of equality can be used to justify steps in solving an equation.
Equation is 4x-1 =27. that means the correct answer is 27
The equals sign is used in mathematical formulas to show that two expressions are equal. In contrast to English, where an equation is defined as any well-formed formula that consists of two expressions joined by the equals sign, French defines an equation as containing one or more variables. The first stage in resolving a variable equation is determining the values of the variables that lead to equality.
Here, 4x-1 =27
We know that x=7
4x=27+1
4x= 28
Therefore x = 28÷4 = 7.

To graph this, we will look at the pieces they gave us. Slope-intercept form equations are written in y = mx + b.
➜ The slope, m, is the pitch of the line. It's "rise over run" and helps us know where the plot points. For this problem, we will rise one value and move 6 values right to the next point.
➜ The y-intercept, b, is where the line intercepts the y-axis. It helps us know where the first point goes (0, y). For this problem, we will graph (0, 4).
