There are 60 min per hour.
There are 24 hours in one day, so there are 60 times 24= 1,440 minutes in a day.
Person A: for 45 minutes per day had a heart rate of 150, and for 1,395 minutes per day had a heart rate of 60.
This means that her heart rate totaled (45x150) + (1,395x60) = 90,450 beats per day.
Person B: for 1,440 minutes per day had a heart rate of 72 beats per minute.
This means that her heart rate totaled (1,440x72) = 103,680 beats per day.

So for 365 days: 365(103,680-90,450)= 4,828,950-this is the number of beats MORE per year of Person B than Person A.

Which of the following statements is true?
Ivahew [28]

The correct answer is C. A scalene triangle can be a right triangle.


This is because a scalene triangle is a triangle where all of the sides and angles are different from one another. This automatically tells us that options A and D are incorrect, because equiangular triangles have all 3 angles equivalent and if two sides were of equal length in the triangle, then it would not be scalene.


This leaves us with options B and C. An obtuse triangle simply has one angle with a measure greater than 90 degrees, and a right triangle is a triangle with a right angle (an angle that measures exactly 90 degrees). Scalene triangles can be both obtuse and right, as long as the side lengths and angles are not equal to one another. This makes option B incorrect, and option C the only correct option out of the four.


Your answer is option C.


Hope this helps!
