Answer:
Step-by-step explanation:
You will need to know the gram weight per mole from the periodic table for the element ( or the molecule of elements) in question.
Answer: 5504
Step-by-step explanation:
This involves us finding the sum of all odd integers from 141 to 203.
We can interpret this as an arithmetic sequence with first term 141 and common difference 2.
This sequence has 
terms.
So, the sum is:
Answer:
Option (4)
Step-by-step explanation:
From the figure attached,
∠b = 75° [Vertical angles]
If the lines f and g are parallel then,
∠b = ∠c [Corresponding angles]
Therefore, ∠c = 75°
Since m∠c + m∠d = 180° [Supplementary angles]
75° + m∠d = 180°
m∠d = 180° - 75°
m∠d = 105°
Therefore, measure of angle d should be equal to 105° to prove f and g are parallel.
Option (4) will be the answer.
Answer:
138.8 cm
Step-by-step explanation:
Angle I =180 - 89 - 38 = 53
Using sine law
i/sinI = k/sinK
180/sin53 = k/sin38
k = 138.76
