What is m angle KNL?
Enter your answer in the box.
Answer:
KNL = 102
Step-by-step explanation:
The angles are vertical angles and vertical angles are equal
5x+2 = 3(x+14)
5x+2 = 3x+42
Subtract 3x from each side
5x-3x+2 = 3x+42-3x
2x+2 = 42
Subtract 2 from each side
2x+2-2 = 42-2
2x = 40
Divide by 2
2x/2 = 40/2
x = 20
We want to find KNL
KNL = 3(x+14) = 3(20+14) = 3 ( 34) = 102
6 = r + 2 Addition and Subtraction Equations 11.2
Answer:
I'm not sure what you are looking for but I'm assuming you are finding r.
r is equal to 4.
Step-by-step explanation:
6 = r + 2
In order to find r, you have to subtract 2 from 6.
So, r = 6 - 2 = 4
Situation: Find the substance's half-life, in days. Round your answer to the nearest tenth. A 33 gram sample of a substance that's used for drug research has a k-value of 0.1081. Enter the correct answer. N = Noe DONE No = initial mass (at time t = 0) 000 OO N = mass at time t k= = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days
Answer:
1051 or..
10.51
Step-by-step explanation:
Since 33=30 and 0.1081 is supposed to be as a percentage since its already a decimal you could just round it and make it into a fraction then once you get the answer to the fraction it would either be 1081 since 0.1081 as a fraction is 1081/10000 or you could make into 10.81 as a decimal but after that you subtract "30 - 1,081" or 10.81 -30" either one of them and each of those numbers would give you the same exact number. Answer: 1051 or as a decimal 10.51

The vertex form of the equation of a parabola is y=(x-5)+16. what is the standard form of the equation
Answer:
x − y = − 11
Step-by-step explanation:
Simplify each only using positive exponents:
2x^-3 • 4x^2
2x^4 • 4x^-3
2x^3y^-3 • 2x
[tex]\frac{2}{x}[/tex]
[tex]\frac{x}{2}[/tex]
[tex]\frac{4x^4}{y^3}[/tex]
Step-by-step explanation:a. 2x^-3 • 4x^2
To solve this using only positive exponents, follow these steps:
i. Rewrite the expression in a clearer form
2x⁻³ . 4x²
ii. The position of the term with negative exponent is changed from denominator to numerator or numerator to denominator depending on its initial position. If it is at the numerator, it is moved to the denominator. If otherwise it is at the denominator, it is moved to the numerator. When this is done, the negative exponent is changed to positive.
In our case, the first term has a negative exponent and it is at the numerator. We therefore move it to the denominator and change the negative exponent to positive as follows;
[tex]\frac{1}{2x^3} . 4x^2[/tex]
iii. We then solve the result as follows;
[tex]\frac{1}{2x^3} . 4x^2[/tex] = [tex]\frac{2}{x}[/tex]
Therefore, 2x⁻³ . 4x² = [tex]\frac{2}{x}[/tex]
b. 2x^4 • 4x^-3
i. Rewrite as follows;
2x⁴ . 4x⁻³
ii. The second term has a negative exponent, therefore swap its position and change the negative exponent to a positive one.
[tex]2x^4 . \frac{1}{4x^3}[/tex]
iii. Now solve by cancelling out common terms in the numerator and denominator. So we have;
[tex]\frac{x}{2}[/tex]
Therefore, 2x⁴ . 4x⁻³ = [tex]\frac{x}{2}[/tex]
c. 2x^3y^-3 • 2x
i. Rewrite as follows;
2x³y⁻³ . 2x
ii. Change position of terms with negative exponents;
[tex]2x^3.\frac{1}{y^3} .2x[/tex]
iii. Now solve;
[tex]\frac{4x^4}{y^3}[/tex]
Therefore, 2x³y⁻³ . 2x = [tex]\frac{4x^4}{y^3}[/tex]

Find the value of g in the figure given below.
Assume that the lines are parallel.
Answer:
d=60-degree (Vertically opposite angles)
e=d=60-degree (Alternate angles)
e+g=180-degree (Being in a straight line)
60+g=180
g=180-60
g=120-degree
Answer:
angle g = 20 degree
Step-by-step explanation:
60 degree + angle g = 180 degree (being co exterior angles)
angle g = 180 - 60
angle g = 120 degree
Note : co interior angles are the angles formed on the exterior of the two parallel lines and which are on the same side of the transversal .
solution set for [4-x/2]=8
Answer:
[tex]x = - 8[/tex]
Step-by-step explanation:
[tex](4 - \frac{x}{2} ) = 8[/tex]
[tex] - \frac{x}{2} = 8 - 4[/tex]
[tex] - \frac{x}{2} = 4[/tex]
[tex] - 2 \times ( - \frac{x}{2} ) = - 2 \times 4[/tex]
[tex]−1 \times (−x)=−2 \times 4[/tex]
[tex]x=−2 \times 4[/tex]
[tex]x = - 8[/tex]

Look at triangle STU:
A right triangle STU is shown with the right angle at T. The length of side ST is labeled as 42 cm, and the length of side TU is labeled as 56 cm.
What is the length (in centimeters) of side SU of the triangle?
70 centimeters
77 centimeters
90 centimeters
98 centimeters
Answer:
70 cm
Step-by-step explanation:
42^2 + 56^2 = c^2
1764 + 3136 = c^2
4900 = c^2
70 = c

The volume of a rectangular prism is 768 ft3. What is the volume of the same shape if the width is changed by a scale factor of 13?
Answer:
The volume is:
[tex]V_{2}=9984\: ft^{3}[/tex]
Step-by-step explanation:
The equation of the volume of a rectangular prism is:
[tex]V=L*W*H[/tex]
Where:
L is the lengthW is the widthH is the heightWe know the volume is 768 ft³ and the new width change a 13 factor, in other words, W(2) = 13W(1), so we can divide each equation of the volume to find the new volume.
[tex]\frac{V_{1}}{V_{2}}=\frac{L*W*H}{L*W*13H}[/tex]
[tex]\frac{768}{V_{2}}=\frac{L*W*H}{L*W*13H}[/tex]
L and W remain constant.
Therefore, we just need to solve it for V(2).
[tex]\frac{768}{V_{2}}=\frac{1}{13}[/tex]
[tex]V_{2}=13*768=9984\: ft^{3}[/tex]

The volume of a cylinder is 156 pi centimeters cubed. What is the volume of a cone with the same base and height as the cylinder?
Answer:
52 pi centimeters cubed
Step-by-step explanation:
volume of a cylinder = πr^2h
Volume of a cone 1/3(πr^2h)
π = 22/7
r = radius
The volume of a cone is one-third that of a cylinder
volume of cone = 156/3 = 52
14. A cellular telephone company recently conducted research into the length of calls (in
minutes) made by customers. In a random sample of 30 calls, the sample mean was
x= 18.6 minutes and the standard deviation was s=5.2 minutes. Construct and interpret
a 90% confidence interval for true mean call length. (4-step process)
Answer:
The correct answer is "16.987, 20213".
Step-by-step explanation:
Given that,
[tex]n=30[/tex]
[tex]\bar x=18.6[/tex]
[tex]s = 5.2[/tex]
[tex]df=30-1[/tex]
[tex]=29[/tex]
[tex]\alpha = 0.10[/tex]
By using the table, the critical values of t will be:
= [tex]\pm 1.699[/tex]
Now,
The confidence interval will be:
= [tex]\bar x \pm \frac{t\times s}{\sqrt{n} }[/tex]
By putting the values, we get
= [tex]18.6 \pm \frac{1.699\times 5.2}{\sqrt{30} }[/tex]
= [tex]16.987,20.213[/tex]
