Answer:
all of the triangles are right triangles
Answer:
Step-by-step explanation:
6g + 4a = 7a
⇔ 6g = 7a - 4a
⇔ 6g = 3a
Divide both side by 6a
⇒ 
⇔

At approximately 4.5 hours.
15.75x + 70 = 13.25x + 81
15.75x - 13.25x = 81 - 70
2.5x = 11
x = 4.4
found to the nearest tenth 4.5
The formula for circumference is 2 x PI x r
Using the circumference we can find the radius:
50.24 = 2 x PI x r
Multiply 2 by PI:
2 x 3.14 = 6.28
50.24 = 6.28 x r
Divide both sides by 6.28:
R = 50.24 / 6.28
R = 8
The radius is 8 units.
