h = −x − 5/x

g = 2x + 6/x

You have been contracted to replace a countertop in a kitchen. You will get paid $1,000 to do the job. You can complete the job in three days working 8 hours a day. You will need to pay the cost of the materials, which is $525, with the $1,000 that you receive to do the job. How much will you be paid per hour for your time?

Answers

Answer:

$19.79 cents (rounded to the nearest cent)

Step-by-step explanation:

first subtract the amount needed for materials from your total pay

(1000 - 525 = 475)

take 475 and divide that among the hours you work.

475 / 24 = 19.7916666

round that number to the closest money value

19.79

The graphic shows the schedule network diagram (in minutes) for assembling a toy train set. What is the duration of the critical path?A) 38 minutes
B) 41 minutes
C) 49 minutes
D) 51 minutes

Answers

D because it is longer than the rest

Final answer:

The critical path in a project schedule is the longest sequence of tasks from start to finish and determines the minimum total duration for the project. Without the diagram, the correct duration from your multiple-choice options cannot be determined accurately. The correct answer represents the duration of the longest path from the given options.

Explanation:

Without the graphic showing the schedule networkdiagram for assembling a toy train set, providing an accurate answer would be difficult. Normally, in project management, a Critical Path represents the longest sequence of tasks (or activities) in a project schedule from start to finish. It determines the minimum total duration required to complete the project. You identify the critical path by adding the times for the activities in each sequence and determining the longest path in the project.

In this case, assuming that you have the diagram in front of you and you've calculated the total duration for all paths, one of the multiple choice options (A) 38 minutes, (B) 41 minutes, (C) 49 minutes, or (D) 51 minutes would represent the duration of the critical path in the network diagram.

the sum of Marys age and her moms age is 67. Three times Marys age increased by 7 is her moms age. How old is Mary and her mother

Answers

Sove the system:

x: Mary´s age
y: Mom´s age:

x + y = 67
3x + 7 = y

Replace y in the first equation:

x + 3x + 7 = 67
4x = 67 - 7
4x = 60
x = 15 yrs.

y = 67 - 15 = 52 yrs

Labels:
-- Mary's age = D (for 'daughter')
-- Mom's age = M (for 'mom')

The problem says 2 things:

   D + M = 67
and
   3D + 7 = M .

Let's subtract 'M' from each side of the first one: D = 67 - M

Now we can plug that into the second one, in place of 'D'.

   3D + 7 = M

   3(67 - M) + 7 = M .

Clear the parentheses on the left side. I assume you know how to do that.

   201 - 3M + 7 = M

Add 3m to each side:

   201 + 7 = 4M

   208 = 4M

Divide each side by 4 :

   52 = Mom's age

Daughter's age = 67 - Mom's age = 67 - 52 = 15

Three times the quantity of a number and 2.5 is 6.6.

Answers

1. Make an equation
3x * 2.5= 6.6
2. Then solve. Get x on its own side

3x*2.5=6.6
/2.5=/2.5
3x=2.64
/3=/3
Then check by substituting .88 as x then you will get 6.6
x=0.88
I hope this helped

Final answer:

The question is a basic algebra problem where we are required to solve for a variable, in this instance 'x'. Upon solving the equation 3x + 2.5 = 6.6, we find that x equals approximately 1.37.

Explanation:

The question is asking us to find a number such that when we multiply it by three and then add 2.5, the result is 6.6. In mathematical terms, we can express this as an equation like this: 3x + 2.5 = 6.6.

To solve this equation first, we need to do the opposite operation of adding 2.5 to the equation on both sides, which involves subtracting 2.5 from both sides of the equation. After doing this, the equation becomes 3x = 6.6 - 2.5, which simplifies to 3x = 4.1.

Next, we do the reverse operation of multiplying the unknown by 3, which is done by dividing both sides of the equation by 3. Therefore, x = 4.1 / 3, which gives us x = 1.36666667. This value, rounded to two decimal places, is 1.37.
