Answer:
C. 1/5 divide by 4
Step-by-step explanation:
When you divide two fractions, you multiply the first fraction by the reciprocal of the other one. To find the reciprocal of the second fraction, yo just have to switch the value of the numerator and denominator (i.e. 4/1's reciprocal is 1/4).
Another important thing to note is that 1/5 x 1/4 is 1/20 because you multiply straight across numerators and denominators.
Now that we have some back ground information, let's which expression leads to 1/20!
A:
1/5 x 2/11/5 x 1/21/10Incorrect Answer ChoiceB:
1/5 x 3/11/5 x 1/31/15Incorrect Answer ChoiceC:
1/5 x 4/11/5 x 1/41/20Correct Answer Choice!Therefore, the answer is C. 1/5 divide by 4.

Absolute value bars ask for the distance of a number and 0 so |-8| is equal to 8 since it is 8 units away from zero, |7| would be equal to 7 since it is 7 units away from 0. To do the more complicated problems simplify the equation as much as possible and then solve.

Michiko claims that to solve the system of linear equations 15x + 8y = 1 and 21x + 4y = -13, instead of multiplying the second equation by –2 and then adding the equations, she could multiply the second equation by 2 and then subtract the second equation from the first equation. Which statement is correct?
A: Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations.
B: Michiko is right for this system of linear equations, and her method will also work for other systems of linear equations.
C: Michiko is wrong because her method will give the opposite of the correct value for x for any system of linear equations.
D: Michiko is wrong because her method will give the opposite of the correct value for y for any system of linear equations.
Answer: B) Michiko is right for this system of linear equations, and her method will also work for other systems of linear equations

Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations, option A is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
To solve the system of linear equations 15x + 8y = 1 and 21x + 4y = -13, Michiko suggests multiplying the second equation by 2 and then subtracting the second equation from the first equation.
Multiplying the second equation by 2 gives:
42x + 8y = -26
Now, subtracting the second equation from the first equation gives:
15x + 8y - (42x + 8y) = 1 - (-26)
Simplifying this equation gives:
-27x = 27
Divide both sides by 27
x=-1
we can substitute x = -1 into either of the original equations.
Using the first equation, we get:
15(-1) + 8y = 1
Simplifying this equation gives:
8y = 16
Dividing both sides by 8 gives:
y = 2
Hence, Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations, option A is correct.

Solve the equation: √x = 3 - (1 / 4)x
Answer:
Let u = √x which gives u2= x and rewrite the given equation in terms of u
u = 3 - u 2 / 4
Multiply all terms by 4, simplify and write the above quadratic in standard form and solve it for u.
u 2 + 4 u - 12 = 0
Two solutions: u = - 6 and u = 2
Use the substitution used above u = √x to solve for x.
u = - 6 = √x has no solution
u = 2 = √x has solution x = 4
Below is shown the graph of the right side of the given equation when written with its right side equal to zero. The x intercept of the graph is the graphical solution to the equation as shown below.
Step-by-step explanation:
Answer: x = 4
Step-by-step explanation:
Given:
√x = 3 - (1 / 4)x
Rewrite:
[tex]\displaystyle \sqrt{x} = 3 - \frac{1}{4}x[/tex]
Square both sides:
[tex]\displaystyle (\sqrt{x} )^{2} = (3 - \frac{1}{4} x)^{2}[/tex]
[tex]\displaystyle x= \frac{1}{16}x^{2} -\frac{3}{2} +9[/tex]
Set the equation equal to 0:
[tex]\displaystyle \frac{-1}{16}x^{2} +\frac{5}{2} -9=0[/tex]
Use the quadratic formula:
[tex]\displaystyle x=\frac{-b\sqrt{b^{2} -4ac} }{2a}[/tex]
[tex]\displaystyle x=\frac{-(\frac{5}{2})\sqrt{(\frac{5}{2})^{2} -4(\frac{-1}{16} )(-9)} }{2(\frac{-1}{16} )}[/tex]
x = 4, 36
Plugging back into equation shows us only one answer works,
x = 4

Answer:
Range = 7
Mean = 7.75
Assumption: Most students will have 7 or 10 letters in their last name
Step-by-step explanation:
Range = Largest - Smallest
= 10 - 3
= 7
Mean = Add the total numbers up to get a total / numbers in the series
= (3+5+2(6)+2(9)+5(7)+4(8)+5(10)) / (1+1+2+5+4+2+5)
= 7.75

Answer:
2. Surface Area = 576m^2
3. Surface Area = 300 yd^2
Step-by-step explanation:
2.
Surface Area of Prism Formula:
Triangle Formula: Area = 1/2 * Base * Height
Left Triangle: Area = 1/2 * 8m * 6m = 1/2 * 48 = 24 m^2
Right Triangle: Area = 24m^2
Rectangle Formula: Area = Length * Width
Top Rectangle: Area = 22m * 6m = 132m^2
Middle Rectangle: Area = 22m * 8m = 176m^2
Bottom Rectangle: Area = 22m * 10m = 220m^2
Add Total Surface Area:
Surface Area = LTrig + RTrig + TopRect + MidRect + BotRect
Surface Area = 24 + 24 + 132 + 176 + 220
Surface Area = 576 m^2

Answer:
x = 37°
x = 40°
x = 260°
Step-by-step explanation:
To find angle x when two secants or tangents intersect outside the circle, simply subtract the smaller arc from the bigger arc and half the result.
Question 1
[tex]x=\dfrac12(128^{\circ}-54^{\circ})=37^{\circ}[/tex]
Question 2
To find the bigger arc, subtract the smaller arc from 360°
⇒ 360° - 140° = 220°
[tex]x=\dfrac12(220^{\circ}-140^{\circ})=40^{\circ}[/tex]
Question 3
The smaller arc can also be found by subtracting the external angle from 180°
Smaller arc = 180° - 80° = 100°
[tex]80^{\circ}=\dfrac12(x-100^{\circ})[/tex]
[tex]160^{\circ}=x-100^{\circ}[/tex]
[tex]x=260^{\circ}[/tex]
#1
2x=128-542x=74x=37°#2
Bigger Arc=360-140=220°
2x=(220-140)2x=80x=40°#3
Smaller arc=180-80=100°
2(80)=x-100160=x-100x=260°
