The perimeter of a rectangle is twice the sum of its lenght and its width. The perimeter is 34 meters and its lenght is 2 meters more than twice its width.
Answers
Answer:
The width of the rectangle is 5 meters, while the length of the rectangle is 12 meters.
Step-by-step explanation:
Given that the perimeter of a rectangle is twice the sum of its lenght and its width, and the perimeter is 34 meters and its lenght is 2 meters more than twice its width, to determine the length and width of the rectangle the following calculation must be done:
(2X + 2 + X) x 2 = 34
(3X + 2) x 2 = 34
6X + 4 = 34
6X = 34 - 4
X = 30/6
X = 5
(2x5 + 2 + 5) x 2 = 34
(10 + 2 + 5) x 2 = 34
17 x 2 = 34
34 = 34
Therefore, the width of the rectangle is 5 meters, while the length of the rectangle is 12 meters.

Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Sample 1 :
Mean = (79.2 + 78.8 + 80 + 78.4 + 81) / 5 = 79.48
Range = 81 - 78.4 = 2.6
Sample 2 :
Mean = (80.5 + 78.7 + 81 + 80.4 + 80.1) / 5 = 80.14
Range = 81 - 78.7 = 2.3
Sample 3 :
Mean = (79.6 + 79.6 + 80.4 + 80.3 + 80.8) / 5 = 80.14
Range = 80.8 - 79.6 = 1.2
Sample 4 :
Mean =(78.9 + 79.4 + 79.7 + 79.4 + 80.6)/5 = 79.6
Range = 80.6 - 78.9 = 1.7
Sample 5 :
Mean = (80.5 + 79.6 + 80.4 + 80.8 + 78.8)/5 = 80.02
Range = 80.8 - 78.8 = 2
Sample 6 :
Mean =(79.7 + 80.6 + 80.5 + 80 + 81.1)/5 = 80.38
Range = 81.1 - 79.7 = 1.4
Xbar = mean of the means
Xbar = (79.48+80.14+80.14+79.6+80.02+80.38) / 6 = 79.96
Rbar = Mean of the sample ranges
Rbar = (2.6 + 2.3 + 1.2 + 1.7 + 2 + 1.4) / 6 = 1.87
n =5 ;D4 = 2.11 ; D3 = 0
From table, D4 = 2.11 ; D3 = 0
Range chart :
Upper Control limit, UCL = D4 * Rbar ; 2.11*1.87 = 3.9457 = 3.95
Lower Control limit, LCL = D3 * Rbar ; 0*1.87 = 0
Mean chart :
Xbar ± A2 * Rbar
From the table :
n = 5 ; A2 = 0.58
Lower control limit(LCL) = Xbar - A2*Rbar
LCL = 79.96 - (0.58*1.87) = 78.8754 = 78.88
Upper Control Limit (UCL) = Xbar + A2*Rbar
UCL = 79.96 + (0.58*1.87) = 81.0446 = 81.04
(78.88 ; 81.04)
The value of Each sample mean falls within the mean interval, Hence, We can conclude that process is on control.

Find the area of the trapezoid
Answers
A=((a+b)/2) x h
So if you plug in the variables it will be
A=((9+15)/2) x 20
A=(24/2) x 20
A=12 x 20
A=240
Therefore, the area of the trapezoid is 240 m^2.
hope this helps!!
Answer:
The area of this trapezoid is equal to 240 [tex]m^{2}[/tex]
Step-by-step explanation:
The area of a trapezoid can be found by using the following formula...
[tex]Area = \frac{(a + b)h}{2}[/tex] (in this formula a and b are the bases of the trapezoid and h is
the height of the trapezoid).
Now we just substitute the values and get...
[tex]Area = \frac{(a + b)h}{2} = \frac{(9 + 15)(20)}{2} = \frac{480}{2} = 240m^{2}[/tex]

What is 90 divided by 1/3 as a fraction?
Answers
Answer:
270/1
Step-by-step explanation:
Here is 90 divided by 1/3 displayed mathematically in colors:
90 ÷ 1/3
The numbers in 90 divided by 1/3 are labeled below:
90 = whole number
1 = numerator
3 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
90x3/1 = 270/1
Answer: 270/1
Step-by-step explanation:
90/1*1/3 you have to do the reciprocal so it turns to 90/1*3/1= 270/1

Pythagorean theorem is [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
So, [tex]a^{2}[/tex] + [tex]3^{2}[/tex] = [tex]13^{2}[/tex]

a. y=11.73*0.94^x
b. y=0.32x^2+1.26x+15.81
c. y=-0.67x+12.41
d. y=-0.32x^2-1.26x+15.81
Answers
Answer:
y = - 0.32x² - 1.26x + 15.81
Step-by-step explanation:
From the graph, it can be deduced that the graph isn't linear nor exponential. The graph shown is a quadratic graph. Hence the regression equation which best fits the model is represented in the form :
y = Ax² + Bx + C
Using technology, the regression model obtained by fitting the data is :
y = - 0.32x² - 1.26x + 15.8
Fitted model is attached below
