315 did
therefore
360-315=45 didnt
45/360 students didnt go on the trip
so to turn this into a percentage, just multiply this fraction by 100:
45/360*100 = 12.5%
Answer:
i dont know tbh
Step-by-step explanation:
good luck
Angle PQR=90 degrees.
cos 52=PQ/14.72
PQ=14.72 x (cos 52)
PQ= 9 cm to the nearest cm
First, set 2x+7 equal to 3x-7 since they are the same angle due to the parallel lines.
2x+7=3x-7
x=14
Then, since 2x+7 and 12y+1 equals 180, put it together to find y:
(2x+7)+(12y+1)=180
(2(14)+7)+(12y+1)=180
12y+1=145
12y=144
y=12
So, x=14 and y=12. Your answer should be C!
