An oil drilling company drills the same distance each day for 5 days. They started at an elevation of 121.175 feet and ended at
nirvana33 [79]

Answer:

x=\dfrac{|-246.875-121.175|}{5}

Step-by-step explanation:

Given that:

Same distance is drilled by the oil drilling company for 5 days.

Initial elevation = 121.175 feet

Final elevation = -246.875 feet

To find:

The equation to find the value of x i.e. the distance drilled each day?

Solution:

To find the distance drilled each day, we need to divide the total distance drilled with the number of days taken to drill the total distance.

Total distance drilled can be found by subtracting the initial elevation from the final elevation and taking modulus because distance can not be negative.

Total distance drilled = | Final elevation - Initial elevation |

Total distance drilled = | -246.875 - 121.175 |

Therefore, we can write the expression as:

x=\dfrac{|-246.875-121.175|}{5}

\Rightarrow x=\dfrac{|-368.05 |}{5} =73.61\ ft/day

Read the question and help me, please.​

<h3>Answer: B) 6</h3>

===============================================

Explanation:

Add the equations by adding the terms straight down.

The x terms add to x+x = 2x.

The y terms add to y+(-y) = y-y = 0y = 0, so the y terms go away

The constants add to 5+7 = 12

The z terms add to -z+z = 0z = 0 and those go away as well

After all that adding, we have 2x = 12 which solves to x = 6 after dividing both sides by 2.

pls help ill give a hundred points. select the correct answer from the drop down menu A(1,3),B(5,3),and D(1,-2) are three vertic
tankabanditka [31]
<h2>Question ↷</h2>

A(1,3),B(5,3),and D(1,-2) are three vertices of rectangle ABCD the coordinates of vertex C are select from the drop down menu (5,2),(-5,1),(5,-2),(2, -5)

<h2>Answer↷</h2>

(5,-2)

<h2>Solution ↷</h2>

we know that,

the midpoint of the diagonals of a rectangle bisect each other,

so,

  • MP of AC = MP of BD

\huge \rightarrow \frac{x + 1}{2},\frac{y+ 3}{2} =  \frac{5 + 1}{2},\frac{3 - 2}{2}  \\

\huge \rightarrow \: x = 5 \:  \\  \huge \rightarrow \: y =  - 2

What is the shape of the cross section taken parallel to the base of a square pyramid
horsena [70]

Answer:

A square

Step-by-step explanation:

A parallel cross section will be the same shape of the base.  Since it's a square base, all parallel cross sections will also be parallel.  Think of it as a different floor of a pyramid shaped building.
