Answer:
B. -21
Step-by-step explanation:
The keyword we have is "below zero". When using the term "below zero" to describe an integer, this means the integer would be a NEGATIVE number. The temperature is 21 degrees below zero meaning its integer form is -21.
Answer:
To be honest I'm not very sure. I think it's either one of the obtuse answers. If not, then feel free to correct me.
Step-by-step explanation:
Answer:
6 ft < L₃ < 30 ft
Step-by-step explanation:
To obtain the answer to the question given above, we must bear in mind that:
The sum of the length of two sides of any triangle is always greater than the 3rd length i.e
L₁ + L₂ > L₃
With the above information in mind, we can obtain the answer to the question given above as follow:
Length 1 (L₁) = 12 feet
Length 2 (L₂) = 18 feet
Length 3 (L₃) =..?
Case 1:
L₁ + L₂ > L₃
12 + 18 > L₃
30 > L₃
L₃ < 30 feet
Case 2:
L₁ + L₃ > L₂
12 + L₃ > 18
Collect like terms
L₃ > 18 – 12
L₃ > 6 feet
Thus,
6 feet < L₃
Combining case 1 and 2,we obtained:
6 ft < L₃ < 30 ft
Therefore, the possible Lenght of the 3rd side is : 6 ft < L₃ < 30 ft
Answer:
The answer is
15=B
16=C
17=D
18=B
19=D
20=D
