27

Step-by-step explanation:

60% of 45 is 27. I hope I could help.

27 scholars have not turned in their forms

Step-by-step explanation:

If there's 45 in total

40% have turned it in

40% of 45 = 18 have turned in the form

45 - 18 = 27 have not turned in their forms

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
