First you have to do puthagorean theorm to find the missing leg which is QR then to find sinS you go opposite over hypotenuse. simplify if needed.
I'm assuming it's 57. Because 1/2 can equal .5 and 56.5+.5=57
Answer for the first box: 38
Answer for the second box: -3
=========================================
Explanations:
To get the first answer, you plug in x = 0 to reflect were at the surface (height is 0)
38-3x = y
y = -3x+38
y = -3*0+38
y = 38
So the temperature at the surface is 38 degrees Celsius
--------------------
Each time x increases by 1 km, y decreases by 3 degrees C. How do we know? Because of the slope m = -3
Note how y = -3x+38 is in the form y = mx+b
m = -3 = -3/1 is the slope
slope = rise/run = -3/1
the "rise" being negative is really a fall or decrease. As we rise higher, the temperature goes down which is expected (It's colder higher up in the atmosphere)
3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4 = 30/4 = 7 1/2
No, Zoey could not make enough servings.
She could use 1/2 cups and have 1/2 of a cup left over.
Zoey would need 2 more cups.
