Answer: The percent of people who were interested in black holes last year was 70%.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
People interested in black holes this year: 62%
If the number is down from the previous year by 8%, to calculate the percent of people who were interested last year we simply have to add the 8% loss to the actual 62 %.
So, mathematically speaking:
62%+8%=70%
In conclusion, the percent of people who were interested in black holes last year was 70%.

The order of finishing is important here, therefore you use permutations rather than combinations. Athlete A winning a gold medal, athlete B silver, and athlete C bronze is not the same as athlete A bronze, athlete B silver and athlete C gold for instance
Perimeter of rectangle is calculated by taking the sum of all the sides of the rectangle. In rectangles the 2 opposite sides are equal length - 3x - 1 breadth - 3x - 3 the formula used to calculate perimeter for rectangle perimeter = (2 x length) + (2 x breadth) substituting length and breadth perimeter = {2 x (3x - 1)} + {2 x (3x - 3)} = 6x - 2 + 6x - 6 = 12x - 8 therefore correct answer is <span>b.12x-8</span>
