Answer:
The second one, I believe :)
Step-by-step explanation:
Answer:
1)42
2)400
3)$2000
Step-by-step explanation:
Q1)
- 35% = 35/100 = 7/20 (simplify)
- (7/20)×120 = 42
Q2)
- Let number = $
- 60% = 60/100 = 3/5
- (3/5)×$ = 240
$ = 240 ÷ (3/5)
= 240 x (5/3)
= 400
Q3)
- Let number = #
- 40% = 40/100 =2/5
- (2/5)×# = $800
# = $800 ÷ (2/5)
= $800 × (5/2)
= $2000
(Correct me if i am wrong)
It is the third option.
If you need any explanation, I can edit this later.
Good luck!!
Answer:
(-infinity, 1) ∪ (1,3) ∪ (3, +infinity)
Step-by-step explanation:
Here only the 2nd function, g(x) = x^2 - 4x + 3, affects the domain. Recognizing that division by zero is undefined, we set g(x) = 0 anyway and solve for x: x^2 - 4x + 3 = 0 = (x -3 )(x - 1) = 0. Thus, x cannot have either value 3 or 1. Using this info, we write the domain as follows:
(-infinity, 1) ∪ (1,3) ∪ (3, +infinity). This is Answer #3.
