Answer:

$1111.11        

Step-by-step explanation:

We have been given that a building contractor is to dig a foundation 50 feet long, 20 feet wide and 10 feet deep.

Let us find the volume of the dirt dig from the foundation.  

\text{Volume of dirt dig from foundation}=50\text{ feet}*20\text{ feet}*10\text{ feet}    

\text{Volume of dirt dig from foundation}=10000\text{ feet}^{3}    

Since, 1 cubic feet= 0.037037 cubic yards. Let us convert volume of dirt dig into cubic yards by multiplying 10,000 by 0.037037.

\text{Volume of dirt dig from foundation}=10000*0.037037=370.3704  

Now let us find how many truckload will hold 370.3704 cubic yards of dirt by dividing 370.3704 by 5.

\text{Number of truckloads needed}=\frac{370.3704 }{5}

\text{Number of truckloads needed}=74.07408

Now let us multiply number of truckloads by 15 to find the total cost to haul away all the dirt.

\text{Total cost}=74.07408*15

\text{Total cost}=1111.1112

Therefore, the cost to have all the dirt hauled away is $1111.11.

Write the equation of the line parallel to the given line and passing through the given point.
Bad White [126]

Answer:

  a)  y = 2x +4

  b)  y = 1/2x +4

  c)  y = -2x +11

Step-by-step explanation:

The given equations are in slope-intercept for, so we can read the slope directly from the equation. It is the x-coefficient.

We can then write an equation of a parallel line using the point-slope form of the equation of a line:

  y -k = m(x -h) . . . . for a line with slope m through point (h, k)

If you like, you can rearrange this to "slope-intercept" form. Add k and simplify.

  y = mx +(k -mh)

__

a) m = 2, (h, k) = (3, 10)

  y = 2x +(10 -2·3)

  y = 2x +4

__

b) m = 1/2, (h, k) = (0, 4)

  y = 1/2x +(4 -(1/2)·0)

  y = 1/2x +4

__

c) m = -2, (h, k) = (4, 3)

  y = -2x +(3 -(-2)(4))

  y = -2x +11

What is the slope of the line that contains the points (-2, 1) and (0, -3)?
spayn [35]

Answer: -2

Step-by-step explanation:

slope = y2 - y1 / x2 - x1

slope = -3 -1 / 0 + 2

slope = -4 / 2

simplify = -2
