Sagot :

Write the numbers on each description as a decimal to find its matching measurement.

About half as many meters as 3*10^3

[tex]\frac{1}{2}\cdot3\times10^3=\frac{1}{2}\cdot3000=1500[/tex]

About three times as many meters as 1*10^1

[tex]3\cdot1\times10^1=3\cdot10=30[/tex]

About half as many meters as 3*10^-3

[tex]\frac{1}{2}\cdot3\times10^{-3}=\frac{1}{2}0.003=0.0015[/tex]

About half as many meters as 9*10^-1

[tex]\frac{1}{2}\cdot9\times10^{-1}=\frac{1}{2}\cdot0.9=0.45[/tex]

About five times as many meters as 2*10^-2

[tex]5\cdot2\times10^{-2}=5\cdot0.02=\text{0}.1[/tex]

About twice as many meters as 2*10^2

[tex]2\cdot2\times10^2=2\cdot200=400[/tex]
