These 2 angles are supplementary so we have
x+ 88 + x + 108 = 180
2x + 196 = 180
2c = -16
x = -8
the 2 angles are -8+88 and -8+108
that is 80 and 100.
Remember that the angles of a triangle is 180 so:
(7x+8) + (5x+2) + (7x-1) = 180
7x+8+5x+2+7x-1=180
7x+5x+7x=180-8-2+1
19x=171
X= 171/19
X=9
Therefore x=9
The initial amount of water was 2.5 million liters
Then 2 million liters remained after evaporation, therefore 0.5 liters evaporated from the swimming pool.
Thus, the percentage will be given by: 0.5/2.5 × 100 = 20%
Hence the answer is 20%

My answer:
Please keep in mind that the number of marbles must be positive because the object can not negative. Moreover, the number of marbles must be an integer number because we can not buy a decimal number of marbles such as 5.5 or 6.5 marbles.
=> the domain for the function must meet 2 requirements:
1. Positive interval
2. Integer number
=> we choose A
Answer:
The population is 9,000 and the sample is 1,080
Step-by-step explanation:
Your population is 9,000 because that is how many people got the survey. The number 182,000 is irrelevant because that information does not matter with regards to the surveys. Your sample is 1080 because that is the number of people that responded.
