Answer:
Present age of Juna = 10 years
Present age of Jubin = 16 years
Step-by-step explanation:
Ratio of present ages = 5: 8
Let the present ages of:
Juna be 5x years and Jubin be 8x years
(where x is the common multiplier of the given ratios)
Four years after:
Juna's age = (5x + 4) years
Jubin's age = (8x + 4) years
According to the question:
(5x + 4) + (8x + 4) = 34
13x + 8 = 34
13x = 34 - 8
13x = 26
x = 26/13
x = 2
5x = 5*2 = 10 years
8x = 8*2 = 16 years
Hence,
Present age of Juna = 10 years
Present age of Jubin = 16 years
Answer:
arc AB = 49°
arc ABC = 253°
arc BAC = 156°
arc ACB = 311°
Step-by-step explanation:
arc AB sees the center angle and it is equal to the center angle it sees
arc ABC is equal to 360 - 107 = 253° because it is also sees center angle
arc BAC is equal to 107 + 49 = 156°
arc ACB is equal to 360 - 49 = 311°
He earns 10 $ per hours
so u just need to find how many hours did he worked.
1 3/4+3 2/3+2 5/6
71/12 hrs
now multiply it by 10
