I got answer choice A for this one.
A rate is a ratio of two quantities: miles per hour, calories per cookie,dollars per person, ... a unit rate just specifies the units (miles, hours) of<span> the two quantities.</span>
The Answer has to be 40 degree's
Log7+log(x-4)=1
Subtract log 7 from both sides
Log(x-4)=1-log7
As 1-log7 = log (10/7)
Log(x-4)=log (10/7)
As bases of logs are same.
we get
x-4=10/7
Add 4 to both sides
x=10/7 + 4
simplify
x=38/7
Answer: x=38/7
Answer:
A=9
Step-by-step explanation:
36=4×9
so last two digits should be divisible by 4,so they can be 16,36,56,76,96
secondly sum of digits should be divisible by 9.
5+9+7+A+6=27+A,so A can be 0 or 9
hence the number can be 59796
