Answer:
Double Replacement.
Explanation:
It's actually simple. Each of those elements have a meaning of a material. So, in this case it's Lead(ii) Chloride + Silver Nitrate = Lead(ii) Nitrate + Silver ChlorideLead(ii).
The two fields of study the principles of biomechanics come from physics and engineering. Biomechanics studies mechanical laws and living organisms. The correct answer is B.
I think that it would be A
<u>Answer</u>
224 Km
4 Km
<u>Explanation</u>
<u>Part 1</u>
The plane flies 100 Km north and then 200 Km east. This makes a 90° turn. To get the distance taken by the plane we get the hypotenuse.
c² = a² + b²
c² = 100² + 200²
= 50,000
c = √50,000
= 223.606 Km
The answer to the nearest whole number is 224 Km
<u>Part 2</u>
If the runner run 15 Km north then 11 Km south, the resultant distance would be,
15 - 11 = 4 Km
The time taken to fill the vat can be found using the least common multiple [LCM]. Given that the first pipe fills the tank in 66 hours and the second one empty the tank in 1010 hours, the time taken to fill the tank will be:
LCM(66,1010)
=66*1010
=66,660 hours
the answer is:
66,660 hours
