Answer:
(a)
(b) 
Step-by-step explanation:
GIVEN: Auditoriums are often designed so that are fewer seats per row for rows closer to the stage. Suppose you are sitting in row
in an auditorium and notice that there are
seats in your row. It appears the row in front of you has
seats and the row behind you has
seats. Suppose this pattern continues throughout the auditorium.
TO FIND: a) How many seats are in the first row b) How many seats are in the
row?
SOLUTION:
total seats in 
total seats in

total seats in 
as it clearly form an A.P. with 
(a)
let total seat in first row be 
as total seats in 



total seats in first row are 
(b)
total seats in
be 



total seats in
row are 
Answer:
Numbers of Tomato plants to be reported in 30 minutes = 5 unit
Step-by-step explanation:
It is given that ,
Time taken to report 20 Tomato plants (P1) = 120 minutes (T1)
Let number of plants to be reported in 30 minutes (T2) = P2
Now , 

So, P2 = 5 unit
Hence the number of plant to be reported in 30 minutes = 5 unit Answer
Answer:
∠MLP = 72° , ∠LJK = 22° , ∠JKL = 72° , ∠KLJ = 86°
Step-by-step explanation:
Here, given In ΔJLK and ΔMLP
Here, JK II ML, LM = MP
∠JLM = 22° and ∠LMP = 36°
Now, As angles opposite to equal sides are equal.
⇒ ∠MLP = ∠MPL = x°
Now, in ΔMLP
By <u>ANGLE SUM PROPERTY</u>: ∠MLP + ∠MPL + ∠LMP = 180°
⇒ x° + x° + 36° = 180°
⇒ 2 x = 180 - 36 = 144
or, x = 72°
⇒ ∠MLP = ∠MPL = 72°
Now,as JK II ML
⇒ ∠LJK = ∠JLM = 22° ( Alternate pair of angles)
Now, by the measure of straight angle:
∠MLP + ∠JLM + ∠JLK = 180° ( Straight angle)
⇒ 72° + 22° + ∠JLK = 180°
or, ∠JLK = 86°
In , in ΔJLK
By <u>ANGLE SUM PROPERTY</u>: ∠JKL + ∠JLK + ∠LJK = 180°
⇒ ∠JKL + 86° + 22° = 180°
⇒ ∠JKL = 180 - 108 = 72 , or ∠JKL = 72°
Hence, from above proof , ∠MLP = 72° , ∠LJK = 22° , ∠JKL = 72° ,
∠KLJ = 86°
Your answer would be 520 micrograms, hope this helps :)
To start off, you have to change 2/3 into 3/2 and then multiply it by 3/4. (Which the equation becomes into 3/4 × 3/2.) Then solve 3/4 × 3/2 =9/8 or 1 and 1/8.
