Answers:

\huge \boxed{T= \frac{P V}{n R} } \\ \\ \\ \\ \huge \boxed{W= \displaystyle \frac{1000C }{tc}}

\rule[225]{225}{2}

Step-by-step explanation:

<h2>8.</h2>

P \cdot V = n \cdot R \cdot T

Dividing both sides by n · R:

\displaystyle \frac{P \cdot V}{n \cdot R} =T

<h2>9.</h2><h2 />

\displaystyle C=\frac{Wtc }{1000}

Multiplying both sides by 1000:

1000C=Wtc

Dividing both sides by tc:

\displaystyle \frac{1000C }{tc}=W

<h2 />

\rule[225]{225}{2}

In an EFE​ Matrix, how much more important is a weight of 0.20 than a weight of​ 0.15? A. ​50% B. ​33% C. ​25% D. ​.05% E. ​5.0%
sergij07 [2.7K]

Answer:  B. ​33%

Step-by-step explanation:

  • In Mathematics , a percentage is basically a process of dividing the numerator by the denominator , then multiply the answer by 100.

We use Mathematical Formula : \dfrac{\text{Difference between the Weight of 0.20 and Weight of 0.15 }}{\text{Weight of 0.15}}\times100

Since , Difference between the Weight of 0.20 and Weight of 0.15  = 0.20-0.15=0.05

Then, substitute the value in formula , we get

=\dfrac{0.05}{0.15}\times100\\\\=\dfrac{5}{15}\times100\\\\ \dfrac{100}{3}\%\approx33\%

Hence, the weight of 0.20 is 33% more important than a weight of​ 0.15.

length of a rectangle is 3 times its width.If its perimeter is 24 centimetres what is the area of the rectangle?​
fgiga [73]

Answer:

<h3>27 cm²</h3>

Step-by-step explanation:

The length is 3 × width.

l = 3w

The perimeter is 24 centimeters.

P = 2l + 2w

24 = 2(3w) + 2w

24 = 6w + 2w

24 = 8w

3 = w

The width is 3 centimeters.

l = 3(3)

l = 9

The length is 9 centimeters.

Area is l × w.

A = l × w

A = 9 × 3

A = 27

The area is 27 squared centimeters.

Find the maximum rate of change of f(x,y) = x2y +2y
nevsk [136]

Answer:

Maximum rate of change at the point (-1,2) = √17

Direction is the direction of the gradient

Step-by-step explanation:

The gradient of a function (scalar or vectorial ) is a vector in the direction of maximum rate of change then

f( x,y ) =  x*2y  + 2y

grad    =  δ/δx i +  δ/δy j + δ/δz k

grad f(x,y)  = [ δ/δx i , δ/δy]  =  [ 2y , x+2 ]

at the point  ( -1 , 2 )

grad f(x,y)  = [4 , 1]

| grad f(x,y) |  =  √ (4)²  + (1)²   =  √17
