Answer: 210
Step-by-step explanation:
We know that the number of combinations of n things taken r at a time is given by :-
So, number of ways to select 3 plants out of 7 =
Also number of ways to arrange them in 3 positions = 3! = 6
Now , total number of arrangements with 1 plant in each spot = (number of ways to select 3 plants out of 7) x (number of ways to arrange them in 3 positions)
= 35 x 6
=210
Hence, required number of ways = 210
Answer:
B.45
Step-by-step explanation:
<h3>A sum of all angles in a triangle is 180°</h3><h3>55+60+x+20=180</h3>
60+55=115
180-115=65
65-20=45
Answer: 45°
Given:
f(x) = (x - 5)/8
g(x) = 8x + 5
Therefore
This means that g(x) is the inverse of f(x) and vice versa.
Answer: g(f(x)) = x
