I don't know if you know something called PEMDAS

Parentheses
Exponent
Multiply
Divide
Add
Subtract

So you would do the -2(-7) first giving you 14

So now we have -62/12 +14

now you would do -62/12 giving you -5.16666667

and now the equation is -5.16666667 + 14 = 8.83333333

I know for a fact, being in Calculus Honors, that what I did to simplify is correct. Using the Order of Operations, or PEMDAS (Commonly remebered as "Please Excuse My Dear Aunt Sally<span>". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".) to simplify this answer is necessary.

If your teacher wrote this problem please inform him or her of Order of Operations before your classmates use it even though its wrong.</span>

svet-max [94.6K]

Answer:

3312 square yards.

Step-by-step explanation:

Given:

The sports field at Patton Elementary School is shaped like a rectangle having:

Length = 72 yards

Breadth = 46 yards

Question asked:

What is the area of the field in square yard ?

Solution:

As here sports field at Patton Elementary School is shaped like a rectangle, thus we will use the formula ;

Area \ of\ rectangle=length \times breadth

                             =72\ yards\times46\ yards\\=3312\ square\ yards

Thus, the area of the  sports field at Patton Elementary School is 3312 square yards.

Triangle XYZ is translated 4 units up and 3 units left to yield ΔX'Y'Z'. What is the distance between any two corresponding poin
Paul [167]

Answer:

The distance between any two corresponding points on ΔXYZ and ΔX'Y'Z′ is equal to 5\ units

Step-by-step explanation:

we know that

To find the distance, apply the Pythagoras Theorem

Let

x ----> the distance between any two corresponding points on ΔXYZ and ΔX'Y'Z′

x=\sqrt{4^{2}+3^{2}} \\ \\x=\sqrt{25}\ units\\ \\x=5\ units

Calculate the volume, that is easy: 

<span>4 x 5 x 2.5 = 50m3 </span>

<span>now, as you did not provided if you use nitrogen in </span>

<span>ntp (normal temperature and pressure - 20c, 1atm) weight is 1.165kg/m3 </span>

<span>or: </span>

<span>stp (standard temperature and pressure - 0c, 1atm) weight is 1.2506 </span>

<span>these are in case of pure nitrogen, as in presented case nitrogen is only 79% we need to change weights to represent that: </span>

<span>ntp - 1.165kg/m3 / 100% x 79% = 0.92035kg/m3 </span>

<span>stp - 1.2506kg/m3 / 100% x 79% = 0.987974kg/m3 </span>

<span>therefore in case of: </span>

<span>ntp, total weight of n2 will be 50m3 x 0.92035kg/m3 = 46.0175kg </span>

<span>stp, total weight of n2 will be 50m3 x 0.987974kg/m3 = 49.3987kg</span>
