Hope I helped ;D
So the length of the arc is given by: l = r*theta, here theta is the intercepted angle in unit radian
So, 80 degrees = 80/360 * 2pi = 4/9 * pi
So l = r * (4/9 * pi), the constant ratio is 4/9 * pi
Answer:
z = 21 ; y= 16
Step-by-step explanation:
first of all we have to isolate a variable.
In second expression we can obtain:
3y = 2z+6
y = 2/3 z + 2
now we have to substitute this value in the first equation and solve it
8(2/3z+2)-5z = 23
16/3z + 16 -5z = 23
16z +48 - 15z = 69
z = 21
now we have to substitute z in the second equation:
y = 2/3 (21) +2
y = 14+ 2 = 16
y = 16
Answer: 1100
Step-by-step explanation: mark x for the total sum.
0.35x+ 0.20x + 495 = x. 495= x-0.35x-0.20x
495= 0.45x. X= 495/0.45
