16 men in 12 days can do 0.5work
1 man 1 day can do 0.5/(16x12) of a work
8days to do 0.5 of a work
1 man 8 days can do 8x0.5/(16x12) = 0.5x(1/24) of a work
... if you notice we need 24 men
... more detail
in8days, 0.5x(1/24) of a work need 1 man
in8days, 0.5 of a work need 0.5/(0.5x(1/24)) = 24 men
point is to find 'amount of work done per man per unit of time' then work out from that.
Answer:
4 is 121
1 is 59
Step-by-step explanation:
7 is equal to 5 which meana both are 59. to find 2, you subtract 59 from 180 which gives you 121, since 2 is equal to 4, its also 121. to find 1, subtract 180 and 121, u get 5o so ya. hope its correct
... angle 1
k = x²+1
dk/dx = 2x
dk = 2xdx
y = (x²+1)³ = k³
dy/dk = 3k²
dy/2xdx = 3k²
dy/dx = 2x(3k²) = 6x(x²+1)²
... angel 2
dy/dx = d[(x²+1)³]/dx
= { d[(x²+1)³]/dx }(d(x²+1) / d(x²+1))
= { d[(x²+1)³]/d(x²+1) }(d(x²+1) / dx )
= { 3(x²+1)² }(2x) = 6x(x²+1)²
The answer is 4! you move 4b to the 5b and subtract which gives you 1b and then you subtract 1 from five giving you 4 and 4/1=4
