Answer:
[tex]4[/tex]
Step-by-step explanation:
if 30days =6workers
20days =?
[tex] = \frac{20 \times 6}{30} \\ = 4[/tex]
Proportions can be inverse, direct, joint or combined.
They need 9 workers to complete the job in 20 days
Represent time with t, and the workers with w.
So, the proportional relationship is:
[tex]t\ \alpha\ \frac 1w[/tex]
Express as an equation
[tex]t\ =\ \frac kw[/tex]
Where k represents the proportionality constant
Make k the subject
[tex]k =wt[/tex]
6 workers complete the job in 30 days.
This means that: w =6, and t =30
So, we have:
[tex]k =6 \times 30[/tex]
[tex]k =180[/tex]
Substitute 180 for k in [tex]k =wt[/tex]
[tex]180 = wt[/tex]
In 20 days. we have:
[tex]180 = w \times 20[/tex]
Divide both sides by 20
[tex]9 = w[/tex]
Rewrite as:
[tex]w = 9[/tex]
Hence, they need 9 workers to complete the job in 20 days

Jeff's father is planning to open a savings account to pay for Jeff's college education. He has found a bank that will pay 5 percent interest compounded daily. How much will he need to deposit initially so that in 14 years the balance will be $199,000?
Answer:
P = $183.14
Step-by-step explanation:
Given:
Rate of interest = 5% daily =0.05
Number of year = 14
Balance = $199,000
Computation:
Assume;
Number of days in a year = 365
199,000 = p[1+(0.05/365)]¹⁴⁽³⁶⁵⁾
199,000 = p[1+(0.001369)⁵¹¹⁰
199,000 = p[1086.59]
P = $183.14

y-4 = -4 (x- (-2) )
y-4 = -4 (x+2)
y-4 = -4x -8
y = -4x -4
Step-by-step explanation:
we are going to use quadratic equation for this particular question . so now we are going to change the signs i.e from negative to positive or from positive to negative(-2 will turns to +2) nd +4 will turns to-4)
therefore, (x+2)(x-4) then we na expand the bracket x(x-4)+2(x-4)

Profit is the amount of money that remains after all expenses of a project have been paid. The year has just ended, and Ajax Construction's owner is anxious to find out if the company had a profitable year. The company was awarded five contracts totaling $7,435,000. The costs associated with each project were: Project 1: $1,245,000 Project 2: $985,689 Project 3: $1,723,000 Project 4: $2,567,054 Project 5: $633,768 How much profit did the company earn?
Answer:
the Profit earned by the company is $280,489
Step-by-step explanation:
Total Cost of 5 projects awarded = $7,435,000
Cost of Project 1 = $1,245,000
Cost of Project 2 = $985,689
Cost of Project 3 = $1,723,000
Cost of Project 4 = $2,567,054
Cost of Project 5 = $633,768
We need to find the profit earned by the company.
First we need to find Total cost spent on all 5 projects.
It can be found by adding cost spent on all projects.
Total cost spent on all 5 projects = Cost of Project 1 + Cost of Project 2 + Cost of Project 3 + Cost of Project 4 + Cost of Project 5
Total cost spent on all 5 projects = $1,245,000+ $985,689 + $1,723,000+ $2,567,054 + $633,768
Total cost spent on all 5 projects = $7,154,511
Now we can calculate profit earned using formula:
Profit earned = Total Cost of 5 projects awarded - Total cost spent on all 5 projects
Profit earned = $7,435,000 - $7,154,511
Profit earned = $1,280,489
So, the Profit earned by the company is $280,489

-10x + 3y = 34
y = -8x
Answer
Step 1: Simplify both sides of the equation.
−10x + 3(−8x) = 34
−10x + −24x = 34
(−10x + −24x) = 34 (Combine Like Terms)
−34x=34
Step 2: Divide both sides by -34.
x=−1
Answer:
x=−1

Solve the following equation to determine the value of x: 3x + (x + 10) + 5x + (2x + 2) = 56
Answer:
I think x = 4.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x + x +10 + 5x + 2x + 2 =56
(3x + x + 5x + 2x) + (10 + 2) = 56 (Combine Like Terms)
11x + 12 = 56
11x + 12 = 56
Step 2: Subtract 12 from both sides.
11x + 12 − 12 = 56 − 12
11x = 44
Step 3: Divide both sides by 11.
11x/11 = 44/11
x = 4

Imagine that you are of traditional college age and you apply for a direct marketing position, and in the interview for the position, you are told that you look to young for the position. You have been discriminated against. This is a violation of:___________
Answer:
when grounds intersect.
Step-by-step explanation:
Analyzing the information related to the question above, it is possible to identify that the candidate for the direct marketing position suffered a violation when the grounds intersect.
It is correct to state this on the basis that the candidate was of traditional university age, but in the interview it is said that young people are sought for the position.
This type of discrimination can occur when the individual is discriminated against due to overlapping of several reasons, in the case of the candidate he was seen as a person older than he appeared to be, even though he was a requested age.
Choose the equation that represents the asymptote of the graph f(x) = 2^x +3.
y = 0
y = 3
x = 0
x = 3
Answer:
x = 0Step-by-step explanation:
The horizontal asymptote occurs at x = 0, Hence the equation that represents the asymptote of the graph is at x = 0
f(x) = 2^x +3.
0 = 2^x +3.
2^x +3. = 0
2^x = -3
log 2^ x = log(-3)
x log2 = log(-3)
x = log(-3)/log 2
Hence the required function is when x = 0
