In year 13, the scientist will put tree wrap around tree 1 to protect it from the winter snow. The height of the tree wrap needs to be 45 inches.The wrap is priced by the square foot. To the nearest square foot, how many square feet of wrap does she need?
Answers
Answer: 3 feet 9 inches
Step-by-step explanation: Hopes this helps
Final answer:
To find the square footage of the tree wrap needed, calculate the area by multiplying the height and width of the wrap. Then, convert the square inches to square feet by dividing by 144.
Explanation:
To find the square footage of the tree wrap needed, we need to calculate the area of the wrap that will be wrapped around the tree. The height of the tree wrap is given as 45 inches. To find the width of the tree wrap, we need to measure the circumference of the tree. Let's say the circumference of tree 1 is 120 inches. To calculate the width, we divide the circumference by 3.14 (pi). So, the width is approximately 38.22 inches (rounded to two decimal places).
To calculate the area of the wrap, we multiply the height by the width. In this case, the area is approximately 1719.9 square inches (rounded to one decimal place). To convert this to square feet, we divide by 144 (since there are 144 square inches in a square foot). So, the approximate square footage of wrap needed is 11.94 square feet.

we do not want negative n so we add n to both sides
n+35=45
now subtract 35 from both sides
n=10
This is an algebraic expression.The answer is 10,because 45-10=35.

The term "ordered pairs" refers to graphing and so it will always be in the order of x,y....x first and then y, ALWAYS, so this tells you that in every potential answer given, that the first number IS x and then
to solve for y (the second number) you must do as the equation states and square x,(the first number in the ordered pair you are testing), (squaring means to times it by itself) and then subtract 2, the answer to that, will give you the solution for y.....so......so try this out for all of the above listed potentially correct answers, only ONE will work out properly
Important: to do the equation, you must remember that a negative times a negative ALWAYS equals a positive....so
-1 * -1 = 1.....then the last step, subtracting 2 (-2)
1 -2 = -1......thus C : -1, -1.... is the only possible answer
