Answer:
Mariana takes the two pills together after 18 hours.
Step-by-step explanation:
Mariana must take two pills; one every 6 hours and another every 9 hours.
She take two pills together. Let she takes the two pills together after t hours at the time when she take initially.
To find the time to take the two pills together, take the least common multiple of 6 and 9.
6 = 2 x 3
9 = 3 x 3
So, the least common multiple is 2 x 3 x 3 = 18
So, she takes the two pills together after 18 hours.

Answer:
To find the dimensions of the flower bed, we can set up an equation based on the given information. Let’s assume the length of the shortest side is x. According to the problem, one side is twice the length of the shortest side, which means it is 2x, and the third side is 15 feet more than the length of the shortest side, which means it is x + 151.
The perimeter of a triangle is the sum of all its sides. In this case, we have:
x + 2x + (x + 15) = 143.
Simplifying the equation, we get:
4x + 15 = 143.
Subtracting 15 from both sides of the equation, we have:
4x = 128.
Dividing both sides of the equation by 4, we find:
x = 32.
Now that we know the value of x, we can find the lengths of all three sides:
Shortest side: x = 32 feet.
Side twice the length of the shortest side: 2x = 64 feet.
Third side: x + 15 = 47 feet.
Therefore, the dimensions of the flower bed are approximately 32 feet, 64 feet, and 47 feet.
