Answer:

223.15 <em>k</em>

Step-by-step explanation:

To convert from Celsius to Kelvin you just have to add 273.15 to the Celsius to get the grades in Kelvin.

So the Formula would be:

<em>K</em>=Cº+273.15

Now you just put the values given into the formula and it would look like this:

<em>K=</em> -50+273.15

<em>K=</em>223.15

And your answer would be that -50º C is in 223.15 kelvin.

Answer:

<h2><em><u>x = 52</u></em></h2>

Step-by-step explanation:

<em><u>Known:</u></em>

What to find = x

Exterior angle = 142

Right angle = 90

<em><u>Unknown:</u></em>

what unknown value is = ?

Interior angle = ?

<em><u>1. Find the angle of the interior angles.</u></em>

180 - 142 = 38

<em><u>2. Add the two known angles</u></em>

38 + 90 = 128

<em><u>3. Subtract from 180</u></em>

180 - 128 = 52

<h2><em><u>x = 52 is the answer.</u></em></h2>

Hope this helped,

carols bikes 1 kilometer east 4 kilometers north and then 5 kilometers east again. how far is caroll from her starting position
Volgvan
That'd be a total of 6 km east and 4 km north.

The distance traveled from Carol's starting point, along the path described, is
1 km + 4 km + 5 km = 10 km.

However, if you want the straight line distance from starting to end point, that would be found using the Pyth. Thm.:

sqrt [ (6 km)^2 + (4 km)^2 ] = sqrt(52) = 2sqrt(13) km

3x = 8 <br> 3x + y = 15<br><br> ???
fiasKO [112]
3x=8

Solve for x by dividing by 3 on both sides

x=8/3

Now plug 8/3 in for x in second equation

3(8/3)+y=15

This gives you

8+y=15

Subtract by 8 on both sides to find y

y=8

Now write it in ordered pair form (x,y)

So your answer is (8/3,8)
