Answer:
5 sqrt(3) =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan 30 = x/15
15 tan 30 = x
15 ( sqrt(3)/3) = x
5 sqrt(3) =x
Answer:
1/2
Step by step solution:
First identify the multiple of 2...
2,4,6,8,10....
Count how many of those number you find on the spinner,
2,2,4,6,8, 5 total
There is 10 sections on the spinner so 5/10
Simplify r/2 by dividing by 5
5/5=1
10/5=2
1/2 is your answer

Answer:
C. 3.33 moles
Step-by-step explanation:
Ammonia decomposes

We have to find the moles of hydrogen formed in 2.22 moles of ammonia.
From the reaction
2 moles of ammonia gives 3 moles of hydrogen
1 mole of ammonia produce hydrogen=3/2 moles
2.22 moles of ammonia produces hydrogen=
moles
Number of moles of hydrogen formed by decomposition of 2.22 moles of ammonia
=
moles
Hence, 3.33 moles of hydrogen are formed in 2.22 moles of ammonia.
Option C is true.
C. 3.33 moles
C.7/20
