A factory manufacturers a metal piece in 32 minutes. New technology allowed the factory to cut the time by 8%. The anther improvement cut the time by 5%.How long does it take to manufacture the piece now ? Round your answer to the nearest minute

28 minutes

Step-by-step explanation:

new length of time = percent reduction x initial time

percent reduction = 100 - 8 = 92%

0.92 x 32 = 29.44

New time after final reduction

(100 - 5%) x 29.44

27.96 = 28 minutes

for the points

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
