Use the log table to estimate the value of log10 8.65.

0.9370

Step-by-step explanation:

The logarithmic table (of base 10) is used like this:

First turn the number in scientific notation, but in this case, the number is small and already in "scientific notation", 8.65.

Take the number 8.65 and divide it, first two numbers first and then all the others, one by one.

Locate 8.6 at the left, then the next number, 5 would be at the top, if you had any other number after the 5 you would look for it in the mean difference part, and then would add the number you get, divided by 1000 to the number you found from 8.6 and 5. The image attached shows a good reference to understand this

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
