We know that
in the triangle QRS
tan Q=RS/SQ
in the triangle XYZ
tan X=YZ/ZX---------> tan X=9/12------> tan X=3/4
so
<span>∆qrs ~ ∆Xyz
</span>tan Q=tan X----------> tan Q=3/4
the answer is
tan Q=3/4

= 4,800 L/h
Answer:
c. 50kg = 50,000g
Step-by-step explanation:
We have to solve these following rule of three to see which of the following is a correct conversion of 50kg.
a)
Each kg has 1000g
So
1kg - 1000g
50kg - xg
x = 50*1000
x = 50,000g
Conversion a) is wrong
b)
Each kg has 1000000mg
So
1kg - 1000000g
50kg - x mg
x = 50*1000000
x = 50,000,000 mg
Conversion b) is wrong
c)
In a), we have already converted 50kg to g. We have verified that 50kg = 50,000g. So c. is correct
d)
In b), we have already converrted 50kg to mg. We have verified that 50kg = 50,000,000g. So d. is wrong
