Answer: 1.2
Explanation . The square root of 1.44 can be written as (1.44)1/2. So (1.44)1/2 = (1.2 × 1.2)1/2 (1.44)1/2 = [(1.2)2]1/2 (1.44)1/2 = (1.2)2/2 (1.44)1/2 = (1.2)1 Thus, √1.44 = 1.2
Answer: 64
Explanation To solve this problem, follow these steps: 1Determine the rate at which one boy assembles machines: 15 boys assemble 30 machines in 1 hour. Therefore, 1 boy assembles 30 machines/ 15 boys = 2 machines per hour Calculate the number of machines 48 boys can assemble in 1 hour: Each boy assembles 2 machines per hour Therefore, 48 boys×2 machines per boy=96 machines per hour. Find out how many machines can be assembled in 40 minutes: 40 minutes is 40/ 60 = 2/ 3 of an hour. Therefore, in 40 minutes, the number of machines assembled is: 96 machines per hour× 2/ 3 of an hour =64 machines
