Answer:2x^2-√(3)
Step-by-step explanation:
Sign change in the conjugate
Therefore we have 2x^2-√(3)
Answer:
D. 46 minutes 12 seconds
Step-by-step explanation:
To find the answer, we need to calculate the least common multiple of 252,308 and 198
252=
×
×7
308=×7×11
198=2××11
Then <em>least common multiple</em> is
××7×11=2772 seconds
2772 = 46×60 + 12
Therefore 2772 secondsis equal to 46 minutes 12 seconds.
For one hour- 4 dollar, so its just in multiples of 4. And A positive linear type.
Answer:
4/5
Step-by-step explanation:
Given that:
Number of options = a, b, c, d, e
Number of correct answer choice = 1
Therefore, number of wrong answers = 4
Recall :
Probability = (number required outcome / number of total possible outcomes)
P(wrong answer) :
Number of Required outcome = number of wrong answer choices = 4
Total answers = 5
Hence,
P(wrong answer) = 4 / 5 = 0.8
Answer: 48.
Step 1: multiple 90 puzzles x 0.4 to find how many she has already completed = 36.
Step 2: subtract the number completed (36) from the total (90). 90-36 = 54
Step 3: subtract the 6 more she will complete. 54-6 = 48
