Answer:

r=\dfrac{PV}{nT}

Step-by-step explanation:

The given equation is :

PV=nrT

Where

P is pressure

V is volume

n is no of moles

r is Gas constant

T is temperature

We need to solve the above equation for r.

Dividing both sides of the above equation by (nT). So,

\dfrac{PV}{nT}=\dfrac{nrT}{nT}\\\\r=\dfrac{PV}{nT}

So, the value of r is equal to \dfrac{PV}{nT}.

Find the LCD of the following list of fractions. --14/10, -12/b
muminat
If I read your post properly, the two fractions are -14/10 and -12/b.

The LCD is found by finding prime factors of each term, then collecting the ones that appear the most.

10 = 2 x 5
b = b

2 x 5 x b = 10b

Work out the perimeter of this semicircle. take pi to be 3.142​
Vanyuwa [196]

Answer:

P = 25.71 cm

Step-by-step explanation:

Perimeter of semicircle = πD/2

Where D=10 cm

P = (3.142)(10)/2

P = (3.142)(5)

P = 15.71 cm

Complete Perimeter of Semicircle = P + Diameter

= 15.71 + 10

= 25.71 cm

It costs $0.60 per ft² to cover a right triangular field with sod. The side lengths of the field are 300 ft, 400 ft, and 500 ft.
algol [13]
In this triangle, we know base & perpendicular are 300 & 400 'cause 500 is the longest side which is hypotenuse 

Now, Area of a triangle = ab/2 = (300)(400)/2 = 120000/2 = 60000

As cost for 1 ft² = $0.60
cost for 60000 ft² = 60000 * 0.60 = $36000

In short, Your Answer would be Option A

Hope this helps!
