Answer:
1 ≤ c ≤ 3
Step-by-step explanation:
In order to meet the standard, the chlorine level (c) must be at least 1 part per million (equal to or greater than 1):
1 ≤ c
At the same time, the level also needs to be no greater than 3 parts per million (equal to or lesser than 3)
c ≤ 3
Combining both inequalities yields (in parts per million):
1 ≤ c ≤ 3.
The compound inequality above describes the acceptable range for chlorine levels.
Answer: Never
Step-by-step explanation:
In a triangle the 3 angles have to add up to 180 degrees and if there are 2 90 degree angles the sum is 180 which is not possible to add more degrees without going over
Answer:
6300 cm^3
Step-by-step explanation:
the volume of one book = 20 × 13 × 1.5 = 900 cm^3
the volume of seven books = 900 × 7 = 6300 cm^3
So, the answer is 6300 cm^3.
x of 3/4 = x10 abd y 19/2 or 11
