Answer: celsius = 5/9 (Fahrenheit - 32)

Step-by-step explanation:

Here, you want to start by looking at the fraction they give you. They say that the degrees celsius (C) are going to be equal to five ninths of (something.)

So, right now, your equation should look like this: C = 5/9 (?) because of stands for multiplication.

Next, you want to figure out what that something is. According to the reading, it'll be the degrees Fahrenheit (F) minus 32. So your something is going to look like this: (F-32)

You know that the equation is C = 5/9 (F - 32) and not C = 5/9 F - 32, because if the 32 were outside the parentheses, the prompt would be written "the temperature in degrees celsius is thirty two less than five ninths of the temperature in degrees Fahrenheit." Instead, the number 32 is explicitly included as part of the number that's being multiplied.

I hope that makes sense!

The area of a rectangular wall of a barn is 192 sq. Ft. It's length is 8 ft. Longer than twice it's width. Find the length and w
Novay_Z [31]

Answer: length = 24 ft

Width = 8 ft

Step-by-step explanation:

Let L represent the length of the barn.

Let W represent the width of the barn.

The area of a rectangular wall of a barn is 192 sq. Ft. This means that

LW = 192- - - - - - - - - - - - - - -1

It's length is 8 ft longer than twice it's width. This means that

L = 2W + 8

Substituting L = 2W + 8 into equation 1, it becomes

W(2W + 8) = 192

2W² + 8W = 192

2W² + 8W - 192 = 0

Dividing through by 2, it becomes

W² + 4W - 96 = 0

W² + 12W - 8W - 96 = 0

W(W + 12) - 8(W + 12) = 0

(W - 8)(W + 12) = 0

W = 8 or W = - 12

Since the width cannot be negative, then W = 8

L = 192/W = 192/8

L = 24

1.) IF f(x)=3x-5 and g(x)=x^2, find (fxg)(3)
kodGreya [7K]
Please use * to denote mult. here, not "x."  "x" is your variable and cannnot also be a symbol for mult.

f(x)g(x) = 3x^3 - 5x^2.

Now let x = 3:

(f*g)(3) = 3(3)^3 - 5(3)^2 = 81-45 =  36  (answer)

Can anyone help me with this. please​
zvonat [6]

Answer:

Step-by-step explanation:

using pythagoras theorem

a^2+b^2=c^2

7^2+KL^2=25^2

49+KL^2=625

KL^2=625-49

KL=\sqrt{576

KL=24

take M as reference angle

using tan rule

tan M=/opposite/adjacent

tan M=KL/ML

tan M=24/7

Which expression gives the magnitude of the magnetic field in the region c < r2 < b (at e?
BaLLatris [955]

The electric currents and magnetic materials have an effect called magnetic field. This magnetic field is specified with its direction and magnitude. The magnitude is the strength of the field.

the magnetic field at a distance r from a long straight wire carrying current I can be calculated with the equation:

B = μ​​ ​I / 2 pi R​​

where <span>μ​​ is a constant, I is the current and R is the radius. </span>
