Suppose you planted 3 trees around the north and west sides of one of the houses worth $100,000 on the map. You have increased the property value of the house by $10,000. In addition, the owner will save an average of$50 per year in heating costs.
Assuming that the homeowner lives in the house for another 20 years.
Then the total dollar value of the trees to the homeowner and the community will be
⇒ 10,000 + 50 x 20
⇒ 10,000 + 1,000
⇒ $11,000

A women drives her car 245 miles in 5 hours at this rate how far will she travel in 7 hours
The woman's average speed is 49 miles per hour, so in 7 hours she will travel 343 miles.
To solve how far a woman will drive in 7 hours at the same rate as she did for 245 miles in 5 hours, we need to calculate her average speed and then use that to find the distance for 7 hours. The average speed is calculated by dividing the total distance by the total time of travel. So in this case, the average speed is 245 miles divided by 5 hours, which is 49 miles per hour.
Next, to find out how far she will travel in 7 hours, we multiply her average speed by the total time of travel. Therefore, 49 miles per hour multiplied by 7 hours equals 343 miles.
On an uphill hike, Ted climbs at a rate of 3 miles an hour. Going down, he runs at a rate of 5 miles an hour. If it takes him 40 minutes longer to climb up than run down, what is the total length of Ted's hike?
So the other guy has the right work but at the end he messed up. The real answer is 10 miles.
By establishing the relationship between Ted's uphill and downhill travel times, we can set up an equation to solve for the one-way distance D of the hike. We find that the one-way distance D is 5 miles, making the total length of the hike 10 miles.
Explanation:On an uphill hike, Ted climbs at a rate of 3 miles an hour. Going down, he runs at a rate of 5 miles an hour. If it takes him 40 minutes longer to climb up than run-down, we need to figure out the total length of Ted's hike.
First, let's establish the relationship between the times it takes Ted to hike up and run down the hill. If T is the time it takes to run down, then the time to hike up is T + 40/60 hours (since 40 minutes is two-thirds of an hour).
Let D be the distance of the hike one way. As Ted climbs up at a rate of 3 miles per hour, the uphill time is D/3. Running down at a rate of 5 miles per hour, the downhill time is D/5. We can set up the following equation:
D/3 = D/5 + 40/60
Multiplying through by 15 to eliminate fractions, we get:
5D = 3D + 10
This simplifies to:
2D = 10
Dividing by 2:
D = 5 miles
Since the total hike involves going up and then down the same distance, the total length of the hike is:
Total Length = 5 miles + 5 miles = 10 miles.

Write the first 4 terms in the sequence defined by the explicit rule f(n)=n^2 - 5 *n^2 means n squared
First four terms of f(n)=3n-1
The first four terms of the function f(x) = 3n - 1 are 2, 5, 8, and 11.
Given,
f(n) = 3n - 1
We need to find the first four terms.
What is a function?A function has an input and an output.
Example:
f(x) = x + 1
x = 1,2,3 are inputs.
f(1) = 1 + 4 = 5
f(2) = 2 + 4 = 6
f(3) = 3 + 4 = 7
5, 6, and 7 are the outputs.
We have,
f(n) = 3n - 1
We can assume that the first four terms can be found with n= 1,2,3,4.
f(1) = 3 x 1 - 1 = 3 - 1 = 2
f(2) = 3 x 2 - 1 = 6 - 1 = 5
f(3) = 3 x 3 - 1 = 9 - 1 = 8
f(4) = 3 x 4 - 1 = 12 - 1 = 11
Thus the first four terms of the function f(x) = 3n - 1 are 2, 5, 8, and 11.

What is speed-distance formula?Speed = Distance/Time – This tells us how slow or fast an object moves. It describes the distance travelled divided by the time taken to cover the distance. Speed is directly Proportional to Distance and Inversely proportional to Time. Hence,Distance = Speed X Time, and
Time = Distance / Speed, as the speed increases the time taken will decrease and vice versa.Given:
A hummingbird can travel up to 15 meters per second.

Final answer:
The lengths of the two legs of the isosceles triangle are equal, and by setting the expressions for these lengths equal to each other and solving for 'x', we find that the length of the base of the triangle is 30 cm.
Explanation:
The perimeter of an isosceles triangle is given as 82 cm. The two legs are represented by the expressions (3x + 2) and (5x - 14). Since it is isosceles, these two expressions must be equal because the lengths of the legs are equal, as stated by the theorem.
First, set the expressions equal to each other to find the value of 'x':
3x + 2 = 5x - 14
We then solve for 'x' by subtracting 3x from both sides and adding 14 to both sides:
16 = 2x
x = 8
After finding 'x', we can determine the length of one of the equal sides by substituting 'x' back into either of the original expressions:
Length of one side = 3x + 2 = 3(8) + 2 = 26 cm
Since we have two sides of the same length, we multiply by 2 to find the total length of the two legs:
Total length of two legs = 26 cm imes 2 = 52 cm
To find the length of the base, subtract the total length of the two legs from the perimeter:
Length of the base = 82 cm - 52 cm = 30 cm.
Therefore, the length of the base of the isosceles triangle is 30 cm.
