Answer:
Width = 10 in
Length = 50 in
Step-by-step explanation:
Define the variables
Let x be the width of the rectangle.If the length is five times its width, then the length of the rectangle is 5x.Given the perimeter is 120 in:
[tex]\begin{aligned}\textsf{Perimeter of a rectangle} & = 2(\sf width + length)\\120 & = 2(x + 5x)\\120 & = 2(6x)\\120 & = 12x\\\dfrac{12x}{12}&=\dfrac{120}{12}\\\implies x&=10\end{aligned}[/tex]
Solution:

Solve the system of equations
Answer:
x = -262/13, y = -5/13, z = 89/13
Step-by-step explanation:
Solve the following system:
{3 z + 4 y = 19 | (equation 1)
z - x = 27 | (equation 2)
-3 y + x = -19 | (equation 3)
Swap equation 1 with equation 2:
{-x + 0 y + z = 27 | (equation 1)
0 x + 4 y + 3 z = 19 | (equation 2)
x - 3 y + 0 z = -19 | (equation 3)
Add equation 1 to equation 3:
{-x + 0 y + z = 27 | (equation 1)
0 x + 4 y + 3 z = 19 | (equation 2)
0 x - 3 y + z = 8 | (equation 3)
Add 3/4 × (equation 2) to equation 3:
{-x + 0 y + z = 27 | (equation 1)
0 x + 4 y + 3 z = 19 | (equation 2)
0 x + 0 y + (13 z)/4 = 89/4 | (equation 3)
Multiply equation 3 by 4:
{-x + 0 y + z = 27 | (equation 1)
0 x + 4 y + 3 z = 19 | (equation 2)
0 x + 0 y + 13 z = 89 | (equation 3)
Divide equation 3 by 13:
{-x + 0 y + z = 27 | (equation 1)
0 x + 4 y + 3 z = 19 | (equation 2)
0 x + 0 y + z = 89/13 | (equation 3)
Subtract 3 × (equation 3) from equation 2:
{-x + 0 y + z = 27 | (equation 1)
0 x + 4 y + 0 z = -20/13 | (equation 2)
0 x + 0 y + z = 89/13 | (equation 3)
Divide equation 2 by 4:
{-x + 0 y + z = 27 | (equation 1)
0 x + y + 0 z = -5/13 | (equation 2)
0 x + 0 y + z = 89/13 | (equation 3)
Subtract equation 3 from equation 1:
{-x + 0 y + 0 z = 262/13 | (equation 1)
0 x + y + 0 z = -5/13 | (equation 2)
0 x + 0 y + z = 89/13 | (equation 3)
Multiply equation 1 by -1:
{x + 0 y + 0 z = -262/13 | (equation 1)
0 x + y + 0 z = -5/13 | (equation 2)
0 x + 0 y + z = 89/13 | (equation 3)
Collect results:
Answer: {x = -262/13, y = -5/13, z = 89/13
which measurements are equivalent to 3 yards
The equivalent measures to 3 yards are;
108 inches and ; 6 ft 36 inches
Here, we want to get the values of the measurements that are equivalent to 3 yards
To do this, we need to know how to convert between the various measure types
We proceed as follows;
Mathematically, 1 yard is 36 inches; also, 1 yard is 3 feet
So, 3 yards is (3*36) = 108 inches
Also, 3 yards is (3*3) = 9 feet
Also, 1 ft is 12 inches;
So, 6 ft 12 inches is 7 feet
108 inches is as seen above, so 3 yards equal this
3 yards is not 108 feet as calculated above
6 ft 36 inches
36 inches is 3 ft; so by addition; 6 ft 36 inches is 9 ft
So, the correct answers here are 108 inches and 6 ft 36 inches

A shipping container is in the form of a right rectangular prism, with dimensions of 30 ft by 8 ft by 7 ft 3 in. If the container holds 1096 cubic feet of shipped goods, what percent is empty?
As per the volume of a rectangular prism, it is found that 34.76% of the container is empty.
Volume of a rectangular prism
The volume of the rectangle prism is calculated by multiplying the length, breadth and height of the prism.
The formula for the volume of rectangle prism is
V = l x w x h
where
l represents the length
w represents the width
h represents the height
Given,
A shipping container is in the form of a right rectangular prism, with dimensions of 30 ft by 8 ft by 7 ft 3 in.
Here we need to find if the container holds 1096 cubic feet of shipped goods, what percent is empty
According to the given question,
Let us consider the length is 30ft, Width is 8ft and Height is 7ft.
Here the value 3ft refers the depth.
That one is also multiplied with the volume.
Therefore, the volume of the container is
=> 8 x 7 x 30
=> 1680
Therefore, the volume of the container is 1680 cubic feet.
So, here we have to percentage of the empty space for that we have to find the difference of them and convert it into percentage,
=> 1680 - 1096
=> 584
The percent of empty space is,
=> x% of 1680 = 584
=> x% = 584/1680
=> x% = 0.3476
=> x = 34.76
Therefore, 34.76% of rectangular prism container is empty.

Write an equation for the line parallel to the given line that contains C.
C(4,6); y=x+7
The equation of the parallel line is….
The equation of the parallel line is y = x + 2.
What is Equation of line?
The equation of line with slope m and y intercept at point b is given as;
y = mx + b
Given that;
The point = C(4, 6)
And, equation of line is y = x + 7
Since, Slope of Parallel lines are always same.
So, The slope of the given line is calculated as;
y = x + 7
m = dy/dx = 1
Thus, Slope of parallel lines is 1.
Since, The equation of line is passes through point C (4, 6).
So, The equation of line with slope(m) 1 and point C(4, 6) is;
y - 6 = 1 (x - 4)
y - 6 = x - 4
y = x - 4 + 6
y = x + 2
Thus, The equation of the parallel line is y = x + 2.

jenny believes that spending one hour studying for economics will increase her grade by 20 points. studying for a second hour will increase her grade by 10 points. she also believes that studying for an hour for history will increase her grade by 15 points, but spending a second hour will increase her grade by only 5 points. jenny has two hours to study. if jenny wants to maximize her scores, what should she do?
If Jenny studies one hour both for economics and history she can gain 10+15=25 points
What is meant by Increasing?Increasing: Growing larger or greater. Therefore, if the derivative of a function is positive, then the function is increasing. Let's consider our example of g(x) = x2. The derivative of g(x) = x2 is g'(x) = 2x. Since we are multiplying x by the positive number 2, it's easy to see that g ' is positive when x is positive and negative when x is negative.
Jenny will receive 15 points if she simply studies economics, which equates to 10 points in the first hour and 5 points in the second.
Jenny will earn 20 points if she exclusively studies history, which equates to 15 points in the first class and 5 points in the second.
Jenny should study economics for one hour, which will get her 10 points, and history for one hour, which will gain her 15 points, for a total of 25 points in the two hours
So we concluded that if Jenny studies one hour both for economics and history she can gain 10+15=25 points

Which 3 measurements could be the dimensions of a right triangle?
(a² + b² = c²)
Answer:
5, 12, 13
Step-by-step explanation:
let a = 5 , b = 12 , c = 13 , then
5² + 12² = 25 + 144 = 169
13² = 169
so a² + b² = c²
Answer:
3, 4, 5
Step-by-step explanation:
In a right triangle, we have 2 legs and a hypotenuse. The hypotenuse equals c, while the other 2 legs are a and b.
Lets say a = 3, b = 4, and c = 5
The formula is a² + b² = c²
3² + 4² = 5²
9 + 16 = 25
25 = 25
Therefore, 3, 4, and 5 can be dimensions of a right triangle.

What is a function?A relation between a collection of inputs and one output for each of those inputs is the definition of a function.
A function is a connection between inputs in which each input is associated with precisely one output.
To put it another way, a function is a relationship between inputs. Each function has both a domain and a codomain or range that it operates inside.
Generally, The progression towards
g(x) = f(x -h) +k
depicts a translation with k units added on top and h units added to the right.
Since you have h equal to 0 and k equal to -2, this means that the graph is moved 0 units to the right and 2 units in the opposite direction of up.
The graph of g may be found by shifting f's graph down by two units.
