Answer:
0
Step-by-step explanation:
log 1/256 - log 125/4
= log ( 1/256 * 4/125)
= log (1/8000)
log (1/8000) - 3 log 1/20)
Now 3 log 1/20 = log (1/20)^3 = log (1 / 8000) so we get
log (1 / 8000) - log (1 / 8000)
= 0
Answer:
2x2x47=188
Step-by-step explanation:
Formula to find the slope:
m = y2-y1 / x2-x1
(4,3); (8,5)
m= 5-3 / 8-4
m = 2/4
m = 1/2
Therefore, the slope of the line that passes through these points is 1/2
Answer:
53 gallons of fuel
Step-by-step explanation:
Step 1: Set up a fraction given the data (Let "x" represent the distance in miles.)

Step 2: Divide the given values (The given values are 10 over 250. We are doing this because we need to know the difference between those two figures.) (Trick: For this case, all you need to do is cancel both zeros and the answer is 0.04 once divided)

Step 3: Multiply the result to the last value (Since we've found the difference between them by division, we will have to do the <em>opposite operation </em>in order to find the answer.)

Therefore, 53 is the amount of gallons of fuel needed.
