A scientist is studying red maple tree growth in a state park. She measured the trunk diameters of a sample of trees in the same

month every other year. The tables show the data for two of the trees. This is the final year in which she will collect data. When her data collection is complete, she will predict future red maple tree growth. 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? A. 22 B. 44 C. 121 D. 261

Write the circumference of a circle with a diameter of 49 inches in terms of pi
AleksAgata [21]

Answer:

153.94

Step-by-step explanation:

c=2r*r

The radius is half of the diameter.

To find the radius you will divide 49 inches by 2.

You should get a total of 24.5

Now that you have your radius you are going to use the circumference formula to solve.

C= 2r*r

C=2(24.5)*(24.5)

type that into the calculator (without the parenthesis) and boom your done!

You answer should be 153.938

then you round to get a total of 153.94

I hope i was able to help!

Peter is x years old and his sister is 5 years older. If the product of their ages is 84, form an equation in x and solve it to
daser333 [38]

Answer:

x^2 + 5x - 84 = 0

x = 7

Step-by-step explanation:

let the sister's age = y

sister's age (y)  = 5 + x  equation 1

xy = 84  equation 2

Make y the subject of the formula in equation 2

y = 84/x

equate equation 1 and 2

84/x = 5 + x  equation 3

Multiply equation 3 by x

84 = 5x + x^2

x^2 + 5x - 84 = 0

tjis can be solved using quadratic equation

x^2 -7x + 12x -84 = 0

x(x + 12) -7(x + 12)

x = 7 or - 12

age cant be negative so his age is 7

At what speed was a train traveling on a trip when it had completed half of the total distance of the trip? The trip was 460 mil
kondor19780726 [428]

Answer:

230 mph in 2 hours

Step-by-step explanation:

first i found out how many miles does the train travel in one hour

460 miles ÷ 4 hours

= 115 mph / 115 miles in one hour

the question asks what was the speed of the train when it completed half the distance

half the distance = 1/2 of 460 =230 miles

230 miles is half the distance of the trip

& we know this is correct because earlier we found out that the train travels 115 miles in one hour & in 2 hours it travels 230 miles

115×2=230.

the one thing that i dont quite know is if you say the train is traveling 115 mph or 230 miles in 2 hours .im not sure of tnat .
