Answer:
707 feet above sea level
Step-by-step explanation:
2 hours and 25 minutes is about 2.4167 hours.
Therefore:
y=8.77x+686
y=8.77(2.4167)+686
y=21.1944+686
y=707.1944
So the hiker's elevation will be approximately 707 feet above sea level
30-5*4+2
30-20+2
10+2
12 is the answer
Answer:
1/4
Step-by-step explanation:
count rise/run to find the slope from A to B rise 1 from A and run 4 to B
m = 1/4
The best approach to this is to use the law of cosine which is stated as
c2 = a2 + b2 â’ 2ab cos(C)
distance a=176.27; distance b=222.34; angle C=38.59; distance c is the missing value.
Hence c²=176.27²+222.34² -2*176.27*222.34cos38.59°= 138.71 miles
