During the summer between tenth grade and eleventh grade a student experienced a growth spurt and grew from 64 inches to 68 inches by what percentage did the students height increase

The growth in percentage between the tenth and elenth grade was 6.25 %.

Step-by-step explanation:

By the end of tenth grade the height was 64 inches, that's a starting point, if we wish to know the growth in percentage we first should compute it in inches by subtracting the current height by the starting height. So we have:

growth = current height-  starting height

growth = 68 - 64 = 4 inches

We now need to find how many percentages 4 inches represents in relation to the starting height. To do that we divide the growth by the starting height and multiply it by 100. We have:

growth(%) = (4/64)*100 = 6.25 %

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
