Help me plz The formula K=59(F−32)+273.15 converts temperatures from Fahrenheit F to Kelvin K.
quester [9]

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

k = 59(f - 32) + 273.15

Subtract the sides of the equation minus -273.15

k - 273.15 = 59(f - 32)

Divided the sides of the equation by 59

\frac{k - 273.15}{59} = \frac{59}{59}  (f - 32)  \\

\frac{k - 273.15}{59} = f - 32 \\

Subtract the sides of the equation plus 32

\frac{k - 273.15}{59} + 32 = f \\

And we're done.

Thanks for watching buddy good luck.

For what values of x and y must the figure have in order to be a parallelogram
erma4kov [3.2K]

<u>Given</u>:

Given that the parallelogram with the lengths 5x, 3x + 1, 2y - 5 and y.

We need to determine the values of x and y.

<u>Values of x and y:</u>

We know the property that the opposite sides of a parallelogram are congruent.

Thus, we have;

5x=2y-5 ------- (1)

3x+1=y  ------- (2)

The value of x and y can be determined using the substitution method.

Substituting equation (2) in equation (1), we have;

5x=2(3x+1)-5

5x=6x+2-5

5x=6x-3

-x=-3

  x=3

Thus, the value of x is 3.

Substituting x = 3 in equation (2), we have;

3(3)+1=y

    9+1=y

         10=y

Thus, the value of y is 10.

Write sin(19°) in terms of cosine.
Leto [7]

Answer:

cos(71)

Step-by-step explanation:

Since 19° is less than 90, we can express this in terms of confunction.

sin(θ) = cos(90-θ)

sin(19) = cos(90-19)

sin(19) = cos(71)
