Answer:

4 workers can do the job in 18 days.

Step-by-step explanation:

The number of days d varies inversely as the number of workers.

We can write it as: [tex]d\: \alpha\: \frac{1}{w} \\d=\frac{k}{w}[/tex]

where k is constant of proportionality

We are given: If it takes 9 days for 8 workers to complete the job, then how many workers would it take to do the job in 18 days.

d = 9, w = 8

d = 18, w =?

First we will find value of k when d = 9, w =8

[tex]d=\frac{k}{w}\\9=\frac{k}{8}\\k=9*8\\k=72[/tex]

The value of k, will remain same as it is constant.

We get k = 72.

So, Now we have d = 18, k = 72 and we need to find w

[tex]d=\frac{k}{w}\\18=\frac{72}{w}\\18w=72\\w=\frac{72}{18}\\w=4[/tex]

So, 4 workers can do the job in 18 days.

Question 1. CQuestion 2. A

Step-by-step explanation:

Question 1

Given equation

(-2/3)x - y = -9

Rewrite in slope-intercept form:

(-2/3)x - y = -9(-2/3)x + 9 = yy = -2/3x + 9

The slope is -2/3 and the y-intercept is 9

Correct answer option is C or third option

Given equation

C = 10 + 0.25m

Correct option is A or the first option.

Evaluate the expression for the given value of x.

4.5 − 1.5 for = 3

Answers

There is no x? Can’t help because information is missing

Answer:

Either 0, 12, or 9 (Possibly)

Step-by-step explanation:

I'm assuming that you forgot to put the x next to 4.5 or 1.5 or that you forgot to put x next to both of them and that =3 means x=3

Case 1 (4.5x - 1.5x, x = 3):

You can simplify this expression because both of the units are the same (x). 4.5x - 1.5x = 3x. Next, you have to plug in 3, which would be 3 * 3 which is 9.

Case 2 (4.5x - 1.5, x = 3):

Plug in 3 and you would get 13.5 (4.5 * 3) - 1.5, which is equal to 12.

Case 3 (4.5 - 1.5x, x = 3):

Plug in 3 and you would get 4.5 - 4.5 (1.5 * 3), and since they are the same, it is equal to 0.

If none of these are the answer or you are asking something else, feel free to comment on this answer

Susan purchased a prepaid phone card for $15. Long distance calls cost 14 cents a minute using this card. Susan used her card only once to make a long distance call. If the remaining credit on her card is $9.26, how many minutes did her call last?

Answers

Answer:

41 minutes

Step-by-step explanation:

Step one:

given data

Susan purchased a prepaid phone card for $15

let the number of minutes be x

and let the total be y

per minute call cost = 14 cents = $0.14 per minute

Hence the expression for the situation is given as

y= 15-0.14x

Step two:

given that the balance after a call is 9.26

9.26=15-0.14x

solve for x

9.26-15= -0.14x

5.74=0.14x

divide both sides by 0.14

x=5.74/0.14

x=41 minutes

determnine if each table shown below represents a function or not.

Answers

                                                 Table 1

Input (x)               1            3           5            5              9

Output (y)             7           16          19          20           28

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

From Table 1, it is clear that:

Each input or x-value of the X set has a unique y-value or output of the Y set. There is no duplicated input (repeated x value).

Therefore, Table 1 represents a function.

                                                Table 2

Input (x)               0.5          7           7            12            15

Output (y)             7           15          10          23           30

 

We already know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

From Table 2, it is clear that:

There is a duplicated input (repeated x value) i.e. x = 7 appears twice. And we can not have repeated input values.

As the input x = 7 is repeated multiple times, thus, the given table 2 does not represent a function.

Therefore,  Table 2 does not represent a function.

solve algebraically for all values of x[tex]\sqrt{x-4} +x=6[/tex]

Answers

Answer:

x=5

sqrt of 5-4=1

then 1 +x(5)=6

The solutions to the equation (√x - 4) + x = 6 are x = 4 and x = 25.

To solve the equation (√x - 4) + x = 6 algebraically, we can follow these steps:

Start with the given equation: (√x - 4) + x = 6.

Begin by isolating the square root term on one side of the equation. Subtract x from both sides:

(√x - 4) + x - x = 6 - x

√x - 4 = 6 - x

Move the constant term to the right side by adding 4 to both sides:

√x - 4 + 4 = 6 - x + 4

√x = 10 - x

Square both sides of the equation to eliminate the square root:

(√x)² = (10 - x)²

x = (10 - x)²

x = (10 - x)(10 - x)

x = 100 - 10x - 10x + x²

x = 100 - 20x + x²

Rearrange the equation to form a quadratic equation:

x² - 21x + 100 = 0

Solve the quadratic equation by factoring, completing the square, or using the quadratic formula. In this case, we can factor the quadratic equation:

(x - 4)(x - 25) = 0

Set each factor equal to zero and solve for x:

x - 4 = 0 or x - 25 = 0

Solving for x in each case:

x = 4 or x = 25

Therefore, the solutions to the equation (√x - 4) + x = 6 are x = 4 and x = 25.

A radio is on sale for $50. If the price represents a 10% discount from the original price, what is the original price to the nearest nickel?

Answers

Answer:

Ok, so the discount is given in a percentage, in this case 10%.  The sale price is going to reflect 10% of the original price minus the discount, so...

Sale $ = original$ - original $ x .10

If we use some algebra, we can reorganize the equation to solve for the original price...

Sale $ = original$ - original $ x .10

Sale $ = original$ (1 - .10)

Sale $ = original$ x .90

original$ = sale$/.90

So now we can plug in our values

original price = 50/.90

original price = 55.55555 = $55.55 to the nearest nickel

Answers

Answer: its C

Step-by-step explanation:

The area of an equilateral triangle can be written as a squared sine (60 degrees) thus Option D is correct.

What is an equilateral triangle?

The triangle in which all three sides are of the same length. In this the all angles are the same 60°.

The area of a triangle can be calculated by,

A = 1/2 x b x h..................1

Where,A - Area of triangle

b - base

h - height

From, Pythagoras Theorem

a² = h² + (a/2)²

h² = a² - (a/2)²

Put the value of “h” in equation 1

A = 1/2 x b x h

A = 1/2 x √[a² - (a/2)²] x h

A =  √3/4 a²

Since √3/4 = sin 60°.

So, the area of an equilateral triangle as a squared sine (60 degrees).
