What round to the nearest hundredth if nessary so how i round 9mi to find the answer which the answer is km

14.48 kilometers

Step-by-step explanation:

To convert miles to kilometers, multiply the length value by 1.609. 9 times 1.609 is 14.481. We need to round this to the nearest hundredth. Since the third decimal digit is 1, we round down. That gets us 14.48 as our answer.

answer: 1, 3 and 5 are correct

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
