If .111... = 1/x, what is x?
Correct answer will get brainliest
Answer:
x = 9
Step-by-step explanation:
When 1 is divided by 9, we understand it is a non-terminating decimal number because the denominator consists of other number other than 2 and 5.
Now, let's get into how to solve for x :
Divide both sides by .111... :
1/.111... x .111... = 1/.111 x 1/x
1 = 1/(x)(.111....)
Multiply both sides by x :
1(x) = (x)/(x)(.111...)
x = 1/.111...
x = 9 (nearest whole number)
Answer:
[tex]\sf 0.\dot{1}=\dfrac{1}{9}[/tex]
Therefore, x = 9
Step-by-step explanation:
To convert 0.11111... to a fraction:
Equation 1
Let: y = 0.11111...
Equation 2
Multiply both sides by 10:
⇒ y · 10 = 0.11111... · 10
⇒ 10y = 1.11111...
Subtract Equation 1 from Equation 2 to eliminate the recurring digits after the decimal:
⇒ 10y - y = 1.1111... - 0.11111...
⇒ 9y = 1
Divide both sides by 9
[tex]\implies \sf y=\dfrac{1}{9}[/tex]
Therefore,
[tex]\sf 0.\dot{1}=\dfrac{1}{9}[/tex]
So if:
[tex]\sf 0.\dot{1}=\dfrac{1}{x}[/tex]
Then x = 9

Decide whether quadrilateral ABCD with vertices 4(-3,0), B(-4,1), C(-1.4), and D(0,3) is a rectangle, rhombus, square, or parallelogram.
Answer: rectangle
Step-by-step explanation:
The options imply the figure is a parallelogram. Furthermore, we can tell that not all the sides are congruent, so we can rule out the possibility that it is a rhombus or a square.
To determine if it is a rectangle, we can use the slope formula to determine if there is a pair of perpendicular sides. If this is the case, then this will be a parallelogram with a right angle, making it a rectangle.

(x-5/6)^2=1/36
Answer:
x = [tex]\frac{2}{3}[/tex] , x = 1
Step-by-step explanation:
(x - [tex]\frac{5}{6}[/tex] )² = [tex]\frac{1}{36}[/tex] ( take square root of both sides )
x - [tex]\frac{5}{6}[/tex] = ± [tex]\sqrt{\frac{1}{36} }[/tex] = ± [tex]\frac{1}{6}[/tex] ( add [tex]\frac{5}{6}[/tex] to both sides )
x = [tex]\frac{5}{6}[/tex] ± [tex]\frac{1}{6}[/tex] , then
x = [tex]\frac{5}{6}[/tex] - [tex]\frac{1}{6}[/tex] = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]
x = [tex]\frac{5}{6}[/tex] + [tex]\frac{1}{6}[/tex] = [tex]\frac{6}{6}[/tex] = 1

Only C and D are trueAnswer:
[tex]k(2) = 2[/tex]
[tex]k(3) = 0[/tex]
Step-by-step explanation:
Given:
[tex]\begin{cases}k(1)=4\\k(n)=k(n-1)-2\end{cases}[/tex]
The function [tex]k(n)[/tex] tells us that each term is 2 less than the preceding term.
Therefore:
[tex]\implies k(1)=4[/tex]
[tex]\implies k(2)=k(1)-2=4-2=2[/tex]
[tex]\implies k(3)=k(2)-2=2-2=0[/tex]
[tex]\implies k(4)=k(3)-2=0-2=-2[/tex]
[tex]\implies k(5)=k(4)-2=-2-2=-4[/tex]
[tex]\implies k(6)=k(5)-2=-4-2=-6[/tex]
Rearranging the formula to make the preceding term the subject:
[tex]\begin{aligned} k(n) & = k(n-1) - 2\\\implies k(n)+2 & = k(n-1)\\k(n-1) & =k(n)+2\end{aligned}[/tex]
Therefore:
[tex]\implies k(1)=4[/tex]
[tex]\implies k(0)=k(1)+2=4+2=6[/tex]
[tex]\implies k(-1)=k(0)+2=6+2=8[/tex]

The mean weight of 8 girls in a group is 35 kg. The individual weights of seven of then
are 35kg, 28kg, 43kg, 25kg, 33kg, 51kg, and 22kg. Find the weight of the 8th girl.
The weight of the 8th girl in the class is 43 kg
How to determine the weight of the 8th girl?The given parameters are:
Mean weight = 35 kg
Weight of 7 girls = 35kg, 28kg, 43kg, 25kg, 33kg, 51kg, and 22kg
Let the weight of the 8th girl be x.
Mean is calculated using:
Mean = Sum/Count
So, we have:
(35+ 28+43+25+33+51+22 + x)/8 = 35
Evaluate the sum
(237 + x)/8 = 35
Multiply both sides by 8
237 + x = 280
Subtract 237 from both sides
x = 43
Hence, the weight of the 8th girl is 43 kg

C. [tex]f(x) = -x^2 - 4x[/tex]
D. [tex]f(x) = -x^2 + 4x[/tex]
Answer:
[tex]f(x) = {x}^{2} + 4x[/tex]
Step-by-step explanation:
The graph is concave up, this means that the leading term x^2 is positive.
[tex]f(x) = {x}^{2} + 4x[/tex]
[tex]y = {x}^{2} + 4x[/tex]
For the x intercept, let y = 0[tex] {x}^{2} + 4x = 0[/tex]
[tex]x(x + 4) = 0[/tex]
[tex]x = 0 \: \: \: or \: \: \: \: x = - 4[/tex]
The x intercepts are:
(0 , 0) and (-4 , 0)
For the y intercept, let x = 0
[tex]y = {0}^{2} + 4(0) = 0[/tex]
y intercept :(0, 0)
For the turning point:[tex]t.p = \frac{x1 + x2}{2} [/tex]
