Answer:
40 Operators
Step-by-step explanation:
if 10 operators worked on 120 pages for 2 hours
P operators will work on the same pages for 30min
note: 2hrs= 120min
10×120min/120= P × 30/120
cross multiply make P subject of the formulaP= 10×120×120/120×30
P = 40 operators
Bob and John are saving money. Bob starts with $15 and saves $4 each week. John starts with $3 and
saves $7 each week. At what week will they have the same amount of money?
Answer:
week 4 each will have $31
Step-by-step explanation:
Answer:
Week 4
Step-by-step explanation:
Bob's savings over the course of 4 weeks
15 + 4 = 19(W1) + 4 = 23(W2) + 4 = 27(W3) + 4 = 31(W4)
John's savings over the course of 4 weeks
3 + 7 = 10(W1) + 7 = 17(W2) + 7 = 24(W3) + 7 = 31 (W4)

−7(x−3)−27=−6
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

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?
$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

Answer:
C is the answer. Can I get a brainliest
Answer:
A
Step-by-step explanation:
1* 2 + 2*0 + 0*(-3) = 2 + 0 + 0 = 2, so is not the option D
2*2 + (-1)*0 + (-1)*(-3) = 4+0+3 = 7, so is option A
will still calculate the last one just to make sure and we should get 6
0*2 + 3*0 + (-2)(-3) = 0+0+6 = 6

(-4,0)
Step-by-step explanation:
1. First, let's graph f(x) = |x + 4|.
(The image is below the explanation).
2. As you can see, the line at first starts going down, but then the turning point occurs at (-4,0). The graph then continues to go upwards.
Therefore, the answer is (-4, 0).

Writing What is 20% of 70? Use pencil and paper. Write a percent problem that asks you to solve for the whole. Write a problem that asks you to solve for the percent
is 20% of 70
(Type a whole number.)
Answer:
= 14
Step-by-step explanation:
So my way of doing it is to simply put 20% in decimal so
20= 0.20
Then multiply that by 70
0.20× 70 = 14%
There are probably other ways to do it but I find this way easier

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
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.

I was given the answer, but was confused of how it got to there—please help!
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
[tex]Solve : 3x = \frac{x}{2} - 5 \\ [/tex]
Correct answer will be mark as brainliest.
Answer:
-2
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.

Answer:
32
Step-by-step explanation:
Since the perimeter of the square is equal to the angle x, then we can simply just solve for the perimeter. In this case, it will be 8 + 8 + 8 + 8, which equals 32.
Remember: The lengths of the square are all equal.
£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?
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
Hope this helps you.
