Answer:
92 miles
Step-by-step explanation:
The area of a square is Length x Width. All sides of a square are equal in length so length = width. This is the same as saying x = length and x = width so X times X equals the area. X times X is X².
This tells you that X² = 529 mi². X would equal the square root of 529 which is 23. 23 x 23 = 529.
Each side of the square is 23 miles. The perimeter is equal to side 1 plus side 2 plus side 3 plus side 4. Again since it is a square all sides are equal.
This mean you can just take 4 x 23 miles. The perimeter = 92 miles
Answer:
2, 5, 14, 41, 122
Step-by-step explanation:
Using the recursive rule with a₁ = 2
a₂ = 3a₁ - 1 = 3(2) - 1 = 6 - 1 = 5
a₃ = 3a₂ - 1 = 3(5) - 1 = 15 - 1 = 14
a₄ = 3a₃ - 1 = 3(14) - 1 = 42 - 1 = 41
a₅ = 3a₄ - 1 = 3(41) - 1 = 123 - 1 = 122
The first 5 terms are 2, 5, 14, 41, 122

2. Sorry, I don't how to put that into words, because i'm trying to use calculators, then figure out how they got their answer.
3. C

3. to get the difference between two numbers, (100 and 50, for example,) you must just simply have them minus each other, like simple math. 100 - 50 = 50.
So your difference between the number 100, and the number 50, are 50.
If a 12 oz bottle of shampoo lasted for 16 weeks, we have a ratio of 12:16 which can be shortened to 3:4.
Now if we have 18 oz bottle we know that it's 1/2 more than 12 oz bottle, so the ratio will be also 1/2 more. So if it was 12:16, the new ratio will be:
12 + (1/2 * 12) : 16 + (1/2 * 16)
12 + 6 : 16 + 8
18 : 24
It means that 18 oz bottle should last for 24 weeks. Of course the ratio has to stay the same in its lowest form in both situations and as 18:24 can be shortened to 3:4, it proves it's correct :)
