Working simultaneously, eight pumps fill in a pool in 32 hours. All pumps work at the same pace. If only half of the pumps are working, in how many hours will the pool be filled in? PLS HURRY will mark brainliest

64 hours

Step-by-step explanation:

With 8 pumps it takes 32 hours to fill a pool. We know this is inverse variation so all the products are the same. 32 * 8 = 256, so now we know we can get the answer by diving 256 by 4, getting 64.

i believe the answer is letter c) 8

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
