Yanka [14]
To calculate this, we have to divide 2 1/2 by 8.

PLEASE HELP WITH THIS
marusya05 [52]

Answer:

Step-by-step explanation:

Start with this equation where 17 is the base, x is the power that 17 must be raised to. Then 2 is the result.

17^x = 2                      Take the log of both sides

log(17^x) = log(2)        Take the x outside the brackets

x log(17) = log(2)         Divide by log 17

x = log(2)/log(17)         Find the values for log  2 and log 17

log(2) = 0.3010

log(17) = 1.230

x = .3010/1.230

x = .2446

Greg knows the mass of his geography book is 954 grams. How many kilograms are equal to 954 grams
GalinKa [24]

Answer:

0.954

Step-by-step explanation: 1 KG is 1,000 grams. So, if his geography book is 954 grams, it’s less than 1,000, so it would be a decimal, as 0.954.
