Answer:
12.247 Hope I helped
Step-by-step explanation:

In a full rotation, 360°, a point on the edge of a gear would travel a distance equal to its circumference. The circumference of a circle is:
C=2πr, and since we are only traveling 150°, we need to set up an appropriate ratio for circumference to the distance the point travels:
d/C=150/360
d=5C/12 and since C=2πr
d=10πr/12
d=5πr/12, and since r=4in
d=5*4π/12 in
d=20π/12 in
d=5π/3 in
d≈5.24 in (to nearest hundredth of an inch)
Answer:
2+2=4+3=7+6=13+8=16+5=21+9=30-8=22+4=26
Answer:
x > 4 or 4<x
Step-by-step explanation:
12<8+x
You can rewrite it for easier look:
8+x>12
Suvtract 8 from both side:
8+x-8>12-8
0+x > 4
x > 4 or 4<x
Hope this help you :3
