Answer:
-log2
Step-by-step explanation:
log4 - log8 = log2² - log2³
= 2log2 - 3log2
= (2 - 3)×log2
= (-1)×log(2)
= -log2
Answer:
180 miles
Step-by-step explanation:
Step one:
capacity of tank= 18.5gallons
vehicle averages 666 miles per tank.
Hence, the vehicle can travel 666 miles on 18.5 gallons
Required
The distance covered on 5 gallons
Step two:
vehicle can travel 666 miles on 18.5 gallons
the vehicle will go x miles on 5 gallons
cross multiply we have
5*666= 18.5*x
3330=18.5x
divide both sides by 18.5
x= 3330/18.5
x=180 miles
Cost of a ticket = $19
So, cost of two tickets = 19 * 2 = $38
Now, he makes, $4.75 in an hour.
Let, the number of hours for that much money = x
It would be: 4.75x = 38
x = 38 / 4.75
x = 8 hours
In short, Your Answer would be 8 hours
Hope this helps!
Answer: 16
Step-by-step explanation:
multiplying by negative exponents can be a little tricky. So (1/4x)^-2 becomes 16/x^2 = __/x^2 so the missing number is 16
