Step-by-step explanation:
To find the number of strings of lights needed for the square patio, divide the perimeter of the square by the length of each string of lights. Round up to the nearest whole number.
To find the number of strings of lights needed, we need to divide the perimeter of the square patio by the length of each string of lights. Since the patio is a square, all sides are equal in length. To find the side length, we can take the square root of the area.
In this case, the area is 225m², so the side length of the square patio is √225m = 15m. The perimeter of the square is 4 times the side length, which is 4 × 15m = 60m. Dividing the perimeter by the length of each string of lights, we get 60m ÷ 25m = 2.4. Since we can't have a fraction of a string of lights, we round up to the nearest whole number. Therefore, 3 strings of lights are needed.

Answer:
Step-by-step explanation:
Let d be the number of days.
We have been that each day Katie finds 12 more seashells on beach, so after collecting shells for d days Katie will have 12d shells.
We are also told that Katie already has 34 seashells in her collection, so total number of shells in Katie collection after d days will be:
As Katie wants to collect over 100 seashells, so the total number of shells collected in d days will be greater than 100. We can represent this information in an inequality as:
Therefore, the inequality can be used to find the number of days, d, it will take Katie to collect over 100 seashells.
In order to find out when Katie will have over 100 seashells, we use the equation 34 + 12d > 100. After simplifying, the inequality is d > 5.5. So, it will take Katie over 5.5 days to collect over 100 shells.
The question states that Katie already has 34 seashells and finds 12 more each day. This can be represented by the equation 34 + 12d, where d represents the number of days. In order to find out when Katie will have more than 100 seashells, we need to set this equation greater than 100 and solve for d.
So, 34 + 12d > 100. If we subtract 34 from both sides, we get 12d > 66. Then, divide both sides by 12 to solve for d. d > 66/12. The value of d in this case turns out to be approximately 5.5.
This means it will take Katie slightly over 5.5 days to collect over 100 seashells, given that she can use fractions of days to find seashells.
