Can someone answer number nine for me i have been stuck on this question for too long plz me

Ground level is 0

who is closer to ground level...
-20 7/9 = - 20.77 (with a line over the 7 because it is repeating)
-20 39/50 = -20.78

so, closer to ground level is the black garden ant at -20 7/9 ft because this is closer to 0 then -20 39/50 ft.

Rounding decimals is very similar to rounding other numbers. if the hundredths and thousandths places of a decimal is forty-nine or less, they are dropped and the tenths place does not change. for example, rounding 0.843 to the nearest tenth would give 0.8. , your welcome !

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8
