3 to 12
Write the ratio in simplest form in both fractions and in decimal form.
4:64
Answer:
Step-by-step explanation:
3 : 12
Both have table of 3 in common so
1 : 4 or 1/4
4 : 64
Both have table of 4 in common
1 : 16 or 1/16
Answer:
Fraction form for number 1: 1/4
Decimal form for number 1: 0.25
Fraction form for number 2: 1/16
Decimal form for number 2: 0.0625
Step-by-step explanation:
For the fraction form for number one, all we have to do is change 3:12 to 3/12. Then we just simplify. 1/4. The decimal for 1/4 is just .25, or one quarter.
For the second one, we need to change 4:64 into 4/64. Then we simplify to 1/16. The decimal is a little bit trickier but it comes out to 0.0625.

What are the 3 possible solutions when solving a system of equations?
Three possible solutions when solving a system of equation are: one solution, no solution, and infinite solutions.
The 3 possible solutions of a system of equations are:
- Unique or one solution
- Infinite solutions
- No solution
In case of a system of linear equations, we can determine the type of its solution as follows:
- If the slopes are different, then their graphs will intercept in one point. Hence, the system of linear equation will have one solution.
- If the slopes are the same but the equation of the lines are different, the lines are parallel, hence they will not intercept. Therefore, there is no solution.
- If the linear equations are exactly (or can be transformed to exactly) the same equations, the solution is infinite.

What is the solution to this system of linear equations y − x 6 y x − 10?
The solution to the system of linear equations is (-8, -2).
NOTE: The problem that is solved here is, 'What is the solution to this system of linear equations? Y - x = 6, Y + x = -10'
The equations with two variables and the largest exponent order of 1 each have one, zero, or an infinite number of solutions, and are referred to as linear equations.
A linear equation with two variables has the conventional form ax + by + c = 0, where x and y are the variables.
Additionally, the answers can be expressed as ordered pairs, like as (x, y). The system of linear equations in two variables is graphically represented by two straight lines, which may intersect, be parallel, or be coincident.
y - x = 6 ----> y = x + 6
y + x = -10 -----> y = - x - 10
As both the equations in terms of y, we get
x + 6 = - x - 10
By further calculation
x + x = - 10 - 6
2x = - 16
Dividing both sides by 2
x = -8
Substituting the value of x in either of the equations
y - x = 6
y - (-8) = 6
So we get
y + 8 = 6
y = 6 - 8
y = - 2
Therefore, the solution to the system of linear equations is (-8, -2).

How to solve a function?
To solve a function, you must determine the value of the function for a given input. This requires finding the equation for the function and then plugging in the given input to find the output. For example, if the function is f(x) = x2 + 2x - 5, and the given input is 3, then the output of the function is f(3) = 12.
1. Substitute the given input, x = 3, into the equation.
2. Simplify the equation: f(3) = 32 + 2(3) - 5
3. Solve the equation: f(3) = 9 + 6 - 5
4. Simplify the equation: f(3) = 12
5. Therefore, the output of the function is f(3) = 12.
To solve a given function, you must first determine the equation for the function. Then, you must substitute the given input into the equation and solve it. In this example, the given input was 3 and the equation for the function was f(x) = x2 + 2x - 5. After plugging in the input of 3, the equation was simplified to f(3) = 9 + 6 - 5, which was further simplified to f(3) = 12. Therefore, the output of the function is f(3) = 12.

cos²x - sin²x
Answer:
cos(2x)
Step-by-step explanation:
To simplify the expression cos²x - sin²x, we can use the identity cos²x - sin²x = cos(2x).
This identity can be derived by using the double angle formula for cosine:
cos(2x) = cos(x + x) = cos(x)cos(x) - sin(x)sin(x) = cos²x - sin²x
Therefore, the expression cos²x - sin²x can be simplified to cos(2x).

ttwo sides of a parallelogram are 390 feet and 350 feet. the measure of the angle between these sides is 52. find the area of the parallelogram to the nearest square foot.
Answer:
107,564feet
Step-by-step explanation:
Area of a parallelogram = absin theta
a and b are the measure of its sides
theta is the angle between the sides
Substitute
Area of a parallelogram = 390*350sin52
Area of a parallelogram = 390 * 275.8037
Area of a parallelogram = 107,563.467sq. feet
Hence the area of the parallelogram to the nearest feet is 107,564feet

Bonus: Mr. Rao is planning on making a shed in his backyard (see his plan in the image below). However, local laws require sheds to be at least 15 feet from the property lines. Describe how Mr. Rao should move his shed to comply with the laws. Be specific about the number of feet and the direction (north, south, east, west) that he should move the shed.
Answer:
North 10 feet, and East 5 feet.
Step-by-step explanation:
So we know that North is ^ way. We also know that East is > way.
These are the two directions we must go, since the property line is both South and West of the shed.
The shed is 10ft East of the property line, and we must be 15ft in that direction. So we must go another 5ft East.
Now, the shed is 5ft North of the property line, and we must be 15ft in that direction. So we must go another 10 feet North.

What is the value of DX for solving simultaneous equations 3x 2y =- 11 and 7x 4y 9 by Cramer's rule?
The value of DX for solving simultaneous equations 3x 2y =- 11 and 7x 4y 9 by Cramer's rule is -13/5.
The general formula for Cramer's rule is
DX = detX/detA
Where detX is the determinant of the matrix formed by replacing the x-column of the original matrix with the constant column vector, and detA is the determinant of the original matrix.
For the given equations,
A = [3, 2; 7, 4]
X = [-11; -9]
Therefore,
detA = 3*4 - 2*7 = -10
detX = 3*(-9) - 2*(-11) = 13
Hence, DX = detX/detA = 13/-10 = -13/5

Answer:
Hence for a patio with Dimension
Length=12.5 feet
Width=9.5 feet
2.4 bags of concrete mix is needed
Step-by-step explanation:
The question is not complete, there is not attachment showing the dimension of the patio
Say the dimension of the patio is
Length=12.5 feet
Width=9.5 feet
Area= Length* Width
Area= 12.5*9.5
Area= 118.75 square feet
One bag of concrete mix will cover 50 square feet
Hence x bags will cover 118.75 square feet
cross multiply
50x= 118.75*1
x= 118.75/50
x= 2.4 bags
Why will the speedup of a parallel algorithm will eventually reach some limit?
The advantages of adding additional processors will decrease as more are added because some portions are always still sequential, and eventually the speedup approaches a limit.
What is a parallel algorithm's speedup factor?The ratio of the compute time for the sequential method to the time for the parallel algorithm represents the speedup of a parallel algorithm over a matching sequential algorithm. n-fold speedup is what we refer to if the speedup factor is n. For instance, if a sequential approach needs 10 minutes to compute while a parallel algorithm needs just 2, then the speedup is 5 times.
The observed speedup is dependent on every aspect of the implementation. For instance, more processors frequently result in speedups that are greater; but, if other programmer are running on the processors concurrently with a programmer using a parallel technique, the speedup may be reduced by those other applications.

Explanation:
The inequality of [tex]\text{y} > 3\text{x}-4[/tex] has the boundary equation [tex]\text{y} = 3\text{x}-4[/tex]
That equation is in the format [tex]\text{y} = m\text{x}+b[/tex] which is slope-intercept form.
m = 3 = slope
b = -4 = y intercept
The positive slope indicates the boundary line goes uphill when moving to the right. However, the graph shows the complete opposite with the line going downhill. This means that the graph cannot possibly be [tex]\text{y} > 3\text{x}-4[/tex]
