To complete the project in 36 days, the construction manager would need to add at least 8 more workers to his current team of 12 workers.

If 12 workers can complete a building project in 54 days, to determine this we can divide the rate of work by the number of workers by the number of days: 12 workers / 54 days = 0.2222 workers/day.

If the construction manager wants to complete the project in 36 days, he needs to increase the rate of work to complete the project in that shorter timeframe. To do this, he can add more workers or increase the productivity of the current workers.

To determine how many more workers the manager needs, we can use the formula:

(number of workers) = (rate of work) x (number of days)

By plugging in the desired rate of work and number of days, we get:

(number of workers) = (0.2222 workers/day) x (36 days) = 7.999 workers

Answer:

Step-by-step explanation:

Given similar triangles DEF and GHF, and side lengths DE = 6, EF = 10, GH = 21, FG = 28, you want the lengths of y=FH and x=FD.

Corresponding sides of similar triangles are proportional. This means ...

  DE/GH = EF/HF = FD/FG

  6/21 = 10/y = x/28

We can multiply by 28 to solve for x:

  x = 28(6/21) = 8

Multiplying by 21y/6 will give the value of y:

  y = (21/6)(10) = 35

The values of x and y are 8 and 35, respectively.

Answer:

(- 6, 0 )

Step-by-step explanation:

x - 4y = - 6 → (1)

2x - 12y = - 12 → (2)

multiplying (1) by - 2 and adding to (2) will eliminate x

- 2x + 8y = 12 → (3)

add (2) and (3) term by term to eliminate x

(2x - 2x) + (- 12y + 8y) = - 12 + 12

0 - 4y = 0

- 4y = 0 , then

y = 0

substitute y = 0 into either of the 2 equations and solve for x

substituting into (1)

x - 4(0) = - 6

x - 0 = - 6

x = - 6

solution is (- 6, 0 )

Answer:

x = -6

y = 0

Step-by-step explanation:

For the first equation, x - 4y = -6, we can move -4y to isolate x. Then, the equation will be: x = -6 + 4y. Now, we can use that x to solve for the second equation, 2x - 12y = -12. Let's plug in x from the first equation down to the second one:

2(-6 + 4y) - 12y = -12

Let's solve:

-12 + 8y - 12y = -12

-4y = 0

y = 0

Now that we have y, we can solve for x. Let's plug in y = 0 for the first problem: x-4(0) = -6

x = -6

Using the pythagorean theorem: The length of the sides of a 45-45-90 triangle can be easily solved using the pythagorean theorem because it is a right angle triangle.

Recall the formula for the Pythagorean theorem: a 2 + b 2 = c 2; a 2 + b 2 = c2.

To determine the value of (mostly) the hypotenuse in a right triangle, the Pythagorean theorem uses the formula a2+b2=c2. The "non-hypotenuse" sides of the triangle (opposite and adjacent) are a and b.

The well-known geometric theorem known as the Pythagorean theorem states that the square on the hypotenuse (the side opposite the right angle) is equal to the sum of the squares on the legs of a right triangle. This is known as a2 + b2 = c2.

Solving a system of equations by substitution involves isolating a variable in one equation, then substituting that expression into the other equation. This allows you to solve for the remaining variable in one equation and then substitute it back into the first equation to find the solution for the other variable.

Here is the general process for solving a system of equations by substitution:

Isolate a variable in one of the equations. This is typically done by adding or subtracting one of the variables from both sides of the equation.

Substitute the isolated expression into the other equation by replacing the corresponding variable with the expression you found in step 1.

Solve the new equation for the remaining variable.

Substitute the value you found for the remaining variable back into the first equation and solve for the other variable.

Check your solution by substituting the values you found for the variables back into both equations to make sure they are true statements.

Write your solution in the form of an ordered pair (x, y)

An example of solving a system of equation by substitution :

2x + 3y = 8

4x - 3y = 2

Isolate a variable in one of the equations, for example:

3y = 8 - 2x

Substitute this expression into the other equation:

4x - 3(8 - 2x) = 2

Solve the new equation for the remaining variable:

4x - 24 + 6x = 2

10x = 26

x = 2.6

Substitute the value you found for x back into the first equation and solve for y:

2(2.6) + 3y = 8
