x= 90° - 63° = 27° (NO perpendicular to AOB)
angle DOB = (90°+90°) -128° (angles on a straight line)
= 180° - 128°
= 52°
y= 180° - x - 63° - angle DOB (angles on a straight line)
=180° - 27° - 63° - 52°
= 38°
I'm not sure of the answer tho^^ good luck!
10 minutes. You see the dip or the part of the graph where it's lower than the other points? Look at how many minutes went past.
Steps to solve:
47.5 + 4.5x ≤ 65
~Subtract 47.5 to both sides
4.5x ≤ 17.5
~Divide 4.5 to both sides
x ≤ 3.8888888889...
So, yes, the friends will have to share snacks.
Best of Luck!
Answer:
8.89cm
Step-by-step explanation:
The ratio is 16:9 (which is one of the most common in TVs)
9:5=16:x
x=(16*5)/9
x=8.88....=8.89
