Answer:
[tex]\frac{1}{9}[/tex]
Step-by-step explanation:
Note the bar above 1 means 1 is repeating , that is
0.111..
We require 2 equations with the repeating digit placed after the decimal point
let x = 0.111.... (1) Multiply both sides by 10
10x = 1.111... (2)
Subtract (1) from (2) thus eliminating the repeating digit
9x = 1 ( divide both sides by 9 )
x = [tex]\frac{1}{9}[/tex]

that was the great answer its 1/10

41. D, 42. B, 43. AStep-by-step explanation:
Sides are 120 m, 170 m, 250 m
41.S is the semi-perimeter and is equal to:
s = (a + b + c)/2 = (120 + 170 + 250)/2 = 270 mCorrect choice is D
42.The area is easy to calculate using the Heron's formula, since we have all three side lengths known.
Correct choice is B
43.Perimeter is:
P = a + b + c = 120 + 170 + 250 = 540 mCorrect choice is A

£20 is divided between Colin, Dan & David so that Colin gets twice as much as Dan, and Dan gets three times as much as David. How much does Colin get?
Answers
Answer:
£12Step-by-step explanation:
Let Colin - x, Dan - y, David - z.
We have:
x + y + z = 20x = 2yy = 3zSubstitute and solve for z:
2y + y + z = 203y + z = 203(3z) + z = 2010z = 20z = 2Now find x and y:
y = 3*2 = 6x = 2*6 = 12Answer:
£12
Step-by-step explanation:
Let the David's money be x
If David gets = x
Dan will get = 3x
Colin gets = 3x x 2
= 6x
So, the total money can be write as
[tex]x + 3x + 6x = 10x[/tex]
So, now let's find the amount of money which David have
[tex]10x = 20 \\ \frac{10x}{10} = \frac{20}{10} \\ x = 2[/tex]
So, David will get £2
And now let's find the amount of money which Colin will get
[tex]6x = 6 \times 2 \\ = 12[/tex]
He will get £12

You are applying for jobs at two companies. Company A offers starting salaries with μ = $41,000 and σ = $1,000. Company B offers starting salaries with μ = $41,000 and σ = $5,000. From which company are you more likely to get an offer of $43,000 or more? Justify your answer
Answers
Company B is likely to get an offer of $43,000 or more.
Here we will use a normal distribution and calculation to calculate z-score for each company.
z-score for the company A = (43,000 - 41,000) / 1000
= 2000/1000= 2
z-score for the company B = (43,000 - 41,000) / 5000
= 2000/5000
0.4
Now we will consult z-tables for Probability(P)
P(x > 43000 ) for A = 1- P( x < 43000) = 1 - 0.9772 = 0.0228
P(x > 43000) for B = 1 - P(x< 43000) = 1 - 0.7734 = 0.2266
Therefore the probability is greater with company B that will likely get an offer of $43,000 or more.

−7(x−3)−27=−6
Answers
To evaluate, we will use PEMDAS, so then parenthesis will come first:
-7x+21-27=-6
We have no exponents, multiplication, or division, so addition/subtraction of like terms will be our next step.
-7x-6=-6
Now we can solve for x. To do this, we will first isolate the -7x by adding 6 to both sides.
-7x=0
We will then isolate x by dividing both sides by -7, which will give us:
x=0
Answer:
x = 0
Step-by-step explanation:
−7(x−3)−27=−6
(-7*x -7*-3) - 27 = -6
-7x + 21 - 27 = -6
-7x - 6 = -6
-7x = 6 - 6
-7x = 0
x = 0
check:
-7(0-3) - 27 = -6
-7*-3 -27 = -6
21 - 27 = -6

Answer:
0.73
Step-by-step explanation:
the probability that it is not X is 1-0.4 = 0.6
The probability that it is not Y is 1-0.5 = 0.5
The probability that it is not Z is 1-0.1 = 0.9
So the probability that it is not any of these is
0.6x0.5x0.9 = 0.27
So the probability that it is X Y or Z is 1-0.27 = 0.73

Pls make brainliest :3
And have an amazing day <3
Answer:
128 pieces can be made after cutting the chain
Solution:
Given that, Amy cut 32 ft of chain into pieces that were each 1/4 ft long
To find: Number of pieces after cutting the chain
From given,
total length of chain = 32 feet
length of 1 piece = 1/4 feet
Thus the number of pieces after cutting the chain can be found by dividing the total length of chain by length of 1 piece
number of pieces = total length of chain/length of 1 piece
Substituting the values, we get
number of pieces = [tex]\frac{32}{1/4}[/tex]
number of pieces = 32 x 4 =128
Thus 128 pieces can be made after cutting the chain

Step-by-step explanation:
As per the provided information in the given question, we have a linear equation. We have to find the value of x.
Here, we'll use transposition method to solve this linear equation.Basically, transposition method is used to solve a linear equation in one variable containing constants and variables. We just transpose the values from RHS to LHS by changing its arithmetic operators. In this way, we solve for the unknown value. During transposing the values, ( + ) changes to ( – ) and vice-versa ; ( × ) changes to ( ÷ ) and vice-versa.
Now, coming back to the question. We have,
[tex]\longmapsto \rm { 3x = \dfrac{x}{2}- 5} \\ [/tex]
Taking the LCM in RHS and performing subtraction.
[tex]\longmapsto \rm { 3x = \dfrac{x - 10}{2}} \\ [/tex]
Transposing 2 from RHS to LHS. Its arithmetic operator will get changed.
[tex]\longmapsto \rm { 3x \times 2 = x - 10} \\ [/tex]
Performing multiplication in LHS.
[tex]\longmapsto \rm { 6x = x - 10} \\ [/tex]
Transposing x from RHS to LHS. Its arithmetic operator will get changed.
[tex]\longmapsto \rm { 6x - x = - 10} \\ [/tex]
Performing subtraction of the terms in LHS.
[tex]\longmapsto \rm { 5x = - 10} \\ [/tex]
Transposing 5 from LHS to RHS. Its arithmetic operator will get changed.
[tex]\longmapsto \rm { x = \cancel{\dfrac{- 10}{5}}} \\ [/tex]
Dividing –10 by 5.
[tex]\longmapsto \underline{\boxed{\bf { x = - 2}}} \; \bigstar \\ [/tex]
Therefore, the value of x is –2.

Tim’s savings account pays a simple annual interest rate of 3.5%. Suppose he deposits $5,500 in the account and makes no additional deposits or withdrawals for 5 years. What will the total value of the account be after 5 years?
Answers
$6462.5
Simple Interest = (Principal × Rate × Time) / 100
SI = (P×R×T) / 100
P = 5500
R = 3.5
T = 5
[substitute the values into the formula]
SI = (5500 × 3.5 × 5) / 100
SI = 96250 / 100
SI = 962.5
Total = Principal + Simple Interest
T = P + SI
T = 5500 + 962.5
T = 6462.5
The total value of the account after 5 years will be $6462.5
