Answer:
3.The angle is 24°
4.120°
Step-by-step explanation:
There are 360° in a complete revolution thus for 15 equally space spokes, the angle between every spoke is given by 360° ÷ 15 =24°
In a clock, a complete revolution yields 360°. For a 20 minutes turn, the minute hand will cover (360° ÷ 12) × 4 =120°
Answer:
130.8
Step-by-step explanation:
i just think that you times 0.40 and 327 and then press = and it should give you 130.8
i hope it works
Solve for d:
(3 (a + x))/b = 2 d - 3 c
(3 (a + x))/b = 2 d - 3 c is equivalent to 2 d - 3 c = (3 (a + x))/b:
2 d - 3 c = (3 (a + x))/b
Add 3 c to both sides:
2 d = 3 c + (3 (a + x))/b
Divide both sides by 2:
Answer: d = (3 c)/2 + (3 (a + x))/(2 b)
-----------------------------
Solve for x:
(3 (a + x))/b = 2 d - 3 c
Multiply both sides by b/3:
a + x = (2 b d)/3 - b c
Subtract a from both sides:
Answer: x = (2 b d)/3 + (-a - b c)
____________________________
Solve for b:
(3 (a + x))/b = 2 d - 3 c
Take the reciprocal of both sides:
b/(3 (a + x)) = 1/(2 d - 3 c)
Multiply both sides by 3 (a + x):
Answer: b = (3 (a + x))/(2 d - 3 c)
