4. A group of 5 people can do a piece of work in 6 hours. Calculate the time a group of 8 people, working at half the rate of the first group could take to complete the same work. (3 mks)

4.8 hours

Step-by-step explanation:

6 hours = 360 minutes (6x60)

360/5 = 72 (minutes per person worked)

72/2= 36 (person working at half productivity)

36x 8= 288 (total minutes of 8 people working at half productivity)

288/60= 4.8 (cover minutes back to hours)

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
