Answer : 2,881.2 vacuum cleaners will be sold three months from now.
Steps:
8400*0.7=5880 -> 1 month from now (It’s 0.7 because it decreases by 30% so 70% will remain)
5880*0.7= 4116 -> 2 months from now
4116*0.7= 2881.2 -> 3 months from now
*note that this solution is based on the assumption that the 30% refers to it decreases by 30% of the previous months amount of vacuum cleaners sold, and not the amount of vacuum cleaners sold this month. If it were based on the amount of vacuum cleaners sold this month, the answer would be 840. (8400*0.1)
Answer:
8,640 Minutes = 6 Days
Step-by-step explanation:
8640 minutes/60 minutes per hr=144 hours
144 hours/24 hrs a day=6 days
To solve the question we need to calculate the total circumference of the wheel plus the rim.
Total diameter will be:
d=(4+4+37+37)=82 cm
hence:
C=πd
C=3.14×82
C=257.48 cm
Thus the total rotations required to cover 95267.6 cm will be:
Rotations=95267.6/257.48
=370 rotations
Answer: D] 370 rotations
