Step-by-step explanation:
xy=k
Value of k ; when ; x = - 3 and y = - 2
Put x = - 3 and y = - 2 into the equation :
(-3)(-2) = k
-3 * - 2 = k
6 = k
The constant of variation k = 6
Answer: about 43.5298
Step-by-step explanation:
We must assume that all workmen work at the same rate, and keep it up forever.
More men ==> fewer days
so the proportion is: 30/25 = x/10
Cross-multiply the proportion:
300 = 25 x
Divide each side by 25 :
x = 300/25 = <u>12 men</u>
