Write the expression 16x + 28 as a product using the GCF(greatest common factor) as one of the factors
16x + 28 = ?(?x?)
Answer:
Ik this is late but the answer is 4(4x + 7)
Step-by-step explanation:
The expression by using the greatest common factor is 4(4x + 7).
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is 16x + 28. The expression by using the greatest common factor is calculated as,
E = 16x + 28
E = 4(4x + 7)
Therefore, the expression using the greatest common factor is 4(4x + 7).

Which sets of side lengths could form a triangle?
A. 3 centimeters, 4 centimeters, 9 centimeters
B. 3 centimeters, 6 centimeters, 9 centimeters
C. 4 centimeters, 5 centimeters, 9 centimeters
D. 4 centimeters, 6 centimeters, 9 centimeters
Answer:
D. 4 centimeters, 6 centimeters, 9 centimeters
Step-by-step explanation:
Considering side length for forming a triangle, most of the time it is about Triangle Inequality Theorem, which for 3 sides length a,b,c, it must satisfy the following set of inequalities:
[tex]a+b>c\\a+c>b\\b+c>a[/tex]
By checking each of them only D satisfy:
[tex]4+6=10>9\\6+9=15>4\\9+4=13>6[/tex]
For simplicity you only have to check if the two shortest sides add up to be larger than the longest side:
[tex]4+6>9[/tex]
Solve the system by substitution. y = 6x – 20
y = -4x
Answer:
(2, -8)
Step-by-step explanation:
y=6x-20
y=-4x
since the bottom equation shows us that y=-4x, we can substitute 4x in place of y in the first equation and solve:
-4x=6x-20
-10x=-20
x=2
since the bottom equation shows y=-4x, and we already know that x=2:
y=-4(2)
y=-8

Answer:
144
Step-by-step explanation
8x6=48
48 divided by 2=24
24x2=48
4x10=40
8x4=32
4x6=24
add them all together so 48+40+32+24=144
A simple random sample of 8 reaction times of NASCAR drivers is selected. The reaction times have a normal distribution. The sample mean is 1.24
sec with a standard deviation of 0.12 sec. Construct a 99% confidence interval for the population standard deviation
Answer:
99% confidence interval is 0.07 < σ < 0.32
Step-by-step explanation:
Given that;
standard deviation s = 0.12 sec
s² = 0.12² = 0.0144
degree of freedom DF = n - 1 = 8 - 1 = 7
99% confidence interval
∝ = 1 - 99% = 1 - 0.99 = 0.01
now, we find x² critical values for ∝/2 = 0.005 and 1 - ∝/2 = ( 1 - 0.005) = 0.995, df = 7
The Lower critical value [tex]X^{2}_{\frac{\alpha }{2}},7[/tex] = 20.2777
The Upper critical value [tex]X^{2}_{1-{\frac{\alpha }{2}},7[/tex] = 0.9893
Now, confidence interval is given by
√[ ( (n-1)×s² ) / ( [tex]X^{2}_{\frac{\alpha }{2}},7[/tex] ) ] < σ < √[ ( (n-1)×s² ) / ( [tex]X^{2}_{1-{\frac{\alpha }{2}},7[/tex] ) ]
so we substitute
√[ ( 7×0.0144 ) / ( 20.2777 ) ] < σ < √[ ( 7×0.0144 ) / ( 0.9893 ) ]
√[ ( 7×0.0144 ) / ( 20.2777 ) ] < σ < √[ ( 7×0.0144 ) / ( 0.9893 ) ]
√0.0049711 < σ < √0.10189
0.0705 < σ < 0.3192
Rounding to the nearest 2 decimal places
0.07 < σ < 0.32
Therefore; 99% confidence interval is 0.07 < σ < 0.32
What single decimal multiplier would you use to decrease by 1% followed by a 4% increase?
Answer:
The single decimal multiplier is 1.0296.
Step-by-step explanation:
Multipliers:
For a decrease of a%, we multiply by: [tex]\frac{100-a}{100}[/tex]
For a increase of a%, we multiply by: [tex]\frac{100+a}{100}[/tex]
For consecutive changes, we multiply the multipliers.
Decrease of 1%
Multiplication by [tex]\frac{100-1}{100} = \frac{99}{100} = 0.99[/tex]
Increase of 4%
Multiplication by [tex]\frac{100+4}{100} = \frac{104}{100} = 1.04[/tex]
Consecutive:
0.99*1.04 = 1.0296
The single decimal multiplier is 1.0296.

4. What is the average speed of the car that covers a distance of
(2y3-7y2 + 5y - 1) km in (2y-1) hour?
5. Multiply (m2 + 2m-2) by the sum of (m + 3 ) and (2m - 3)
Answer:
[tex]Area = x^2- 25[/tex]
[tex]Area =9x^2 +24x + 16[/tex]
[tex]Length = (3x -2)[/tex]
[tex]Speed = \left(y^2-3y+1\right)[/tex]
[tex]Product = 3m^3 + 6m^2 - 6m[/tex]
Step-by-step explanation:
Solving (1):
[tex]Length = (x + 5)[/tex]
[tex]Width = (x - 5)[/tex]
Required
Calculate Area
[tex]Area = Length * Width[/tex]
[tex]Area = (x + 5) * (x - 5)[/tex]
[tex]Area = x^2 + 5x - 5x - 25[/tex]
[tex]Area = x^2- 25[/tex]
Solving (2):
Given
[tex]Length = (3x + 4)[/tex]
Required: Calculate Area
[tex]Area =Length * Length[/tex]
[tex]Area =(3x + 4) * (3x + 4)[/tex]
[tex]Area =9x^2 + 12x + 12x + 16[/tex]
[tex]Area =9x^2 +24x + 16[/tex]
Solving (3):
[tex]Area = 3x^2 + 7x - 6[/tex]
[tex]Width = x + 3[/tex]
Required: Calculate Length
[tex]Area = Length * Width[/tex]
[tex]Length = \frac{Area}{Width}[/tex]
[tex]Length = \frac{3x^2 + 7x - 6}{x + 3}[/tex]
Factorize the numerator
[tex]Length = \frac{3x^2 + 9x -2x - 6}{x + 3}[/tex]
[tex]Length = \frac{3x(x + 3) -2(x + 3)}{x + 3}[/tex]
[tex]Length = \frac{(3x -2) (x + 3)}{x + 3}[/tex]
Divide by x + 3
[tex]Length = (3x -2)[/tex]
Solving (4):
[tex]Distance = (2y^3 - 7y^2 + 5y -1)[/tex]
[tex]Time = 2y - 1[/tex]
Required: Determine the average speed
This is calculated as:
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Speed = \frac{2y^3 - 7y^2 + 5y -1}{2y - 1}[/tex]
Factorize the numerator
[tex]Speed = \frac{\left(2y-1\right)\left(y^2-3y+1\right)}{2y - 1}[/tex]
[tex]Speed = \left(y^2-3y+1\right)[/tex]
Solving (5):
Multiply [tex](m^2 + 2m - 2)[/tex] by sum of [tex](m + 3)[/tex] and [tex](2m - 3)[/tex]
First, calculate the sum:
[tex]Sum = m + 3 + 2m - 3[/tex]
[tex]Sum = m + 2m+3 - 3[/tex]
[tex]Sum = 3m[/tex]
Then, the product
[tex]Product = (m^2 + 2m - 2)(3m)[/tex]
[tex]Product = 3m^3 + 6m^2 - 6m[/tex]

cereal
13.5 in.
2.5 in.
8 in.
Total surface area?
Answer:
323.5 square inches
Step-by-step explanation:
The cereal box is not shown. However, the given details are enough to arrive at a solution
[tex]Length = 13.5in[/tex]
[tex]Width = 2.5in[/tex]
[tex]Height = 8in[/tex]
Required
The total surface area (TSA)
This is calculated as:
[tex]TSA = 2 * (Length * Width + Length * Height + Width * Height)[/tex]
[tex]TSA = 2 * (13.5 * 2.5 + 13.5 * 8 + 2.5 * 8)[/tex]
[tex]TSA = 2 * (161.75)[/tex]
[tex]TSA = 323.5[/tex]
Hence, the total surface area is 323.5 square inches
