One can convert temperature from Kelvin into Fahrenheit using the formula F=95(K−273)+32. What is the temperature in Kelvin corr

DiKsa [7]

Answer:

The temperature in Kelvin corresponding to F degrees Fahrenheit is $K=\frac{F-32}{95}+273$

Step-by-step explanation:

Given : One can convert temperature from Kelvin into Fahrenheit using the formula $F=95(K-273)+32$ .

To find : What is the temperature in Kelvin corresponding to F degrees Fahrenheit?

Solution :

Temperature from Kelvin into Fahrenheit is given by,

$F=95(K-273)+32$

Writing Kelvin in terms of Fahrenheit,

Subtract 32 both side,

$F-32=95(K-273)$

Divide by 95 both side,

$\frac{F-32}{95}=K-273$

Add 273 both side,

$\frac{F-32}{95}+273=K$

Therefore, The temperature in Kelvin corresponding to F degrees Fahrenheit is $K=\frac{F-32}{95}+273$

What line is parallel to 2x+5y=6 that goes through (5,3)

Anna11 [10]

Answer:

4y = x - 17

Step-by-step explanation:

First off, in the equation given : 2x + 5y = 6 , make y the subject of the formula which will give y = $\frac{-2x}{5}$ + $\frac{6}{5}$ which make the gradient, m, the coefficient of x = $\frac{-2}{5}$ . Since the line we're looking for is parallel to the one we were given, their respective gradients would be the same. (If they were perpendicular, the gradient of the new line would be a negative inverse of the given line)
