Step-by-step explanation:
A) 30:40=3:4
B) 30:70=3:7
C) 2:1
D) 8:6=4:3
Answer:
2
Step-by-step explanation:
1) Take the natural log of both sides, obtaining:
-0.20x + ln 3.80 = ln 2
2) Group the ln terms on the right side: -0.20x = ln 2 - ln 3.80
3) Find the natural logs of 2 and 3.80 and combine them: -0.408, so that we have 0.20x = 0.408.
4) Solving for x, we get 2.03, or approx 2 (Answer C)
Answer:
the answer is a. 89 miles
Step-by-step explanation:
first you do 59.40 x 3 = 178.47
