according to the 2010 United States census the population of a town was 89154 roughly a 12% increase from 79601 in 2000 constructing Expo Neo model to predict the town's population Each decade use your model to predict the population of the town in 2040
Final answer:
To predict the population of the town in 2040 using an exponential growth model, we can use the formula P(t) = P₀ * (1 + r)^(t - t₀), where P(t) is the population at time t, P₀ is the initial population, r is the growth rate, and t₀ is the initial time. Given the population in 2010 and 2000, we can calculate the growth rate and substitute the values into the formula to predict the population in 2040.
Explanation:
To construct an exponential growth model to predict the population of the town in 2040, we can use the formula P(t) = P₀ * (1 + r)^(t - t₀), where P(t) is the population at time t, P₀ is the initial population, r is the growth rate, and t₀ is the initial time.
Given that the population in 2010 was 89154 and in 2000 was 79601, we can calculate the growth rate as follows:
Growth rate = (Population in 2010 - Population in 2000) / Population in 2000 * 100%
Growth rate = (89154 - 79601) / 79601 * 100%
Growth rate ≈ 11.98%
Now we can substitute the values into the exponential growth model and predict the population in 2040, which is 30 years after 2010:
P(2040) = 89154 * (1 + 0.1198)^(2040 - 2010)
P(2040) ≈ 89154 * 1.1198^30 ≈ 89154 * 4.676
P(2040) ≈ 417204.504

Iona's favorite peaches are are $2.50 per pound at the local Farmers Market she bought 3.5 lb of peaches how much did she spend
Final answer:
Iona spent $8.75 on peaches after buying 3.5 pounds at $2.50 per pound at the local Farmers Market.
Explanation:
Iona's favorite peaches cost $2.50 per pound at the local Farmers Market, and she purchased 3.5 pounds of peaches. To calculate the total cost, we multiply the price per pound by the number of pounds purchased:
Total cost = Price per pound × Number of pounds
Total cost = $2.50 × 3.5
Total cost = $8.75
Therefore, Iona spent $8.75 for the peaches at the local Farmers Market.

Stefano had $46 in a bank account that he was not using. Each month
for three months, the bank withdrew ¼ of this amount as a service fee.
How much was left in the account after the last withdrawal?
Final answer:
After three monthly withdrawals of ¼ of the account balance from Stefano's initial $46, he is left with $19.41 in his account.
Explanation:
To calculate how much money Stefano has left in the account after each monthly withdrawal of ¼ of the account balance, we will need to subtract ¼ of the balance three times, once for each month.
Initial amount in Stefano's account: $46
First withdrawal: 1/4 of $46 = $11.50 Stefano's balance after first withdrawal: $46 - $11.50 = $34.50
Second withdrawal: 1/4 of $34.50 = $8.625 Stefano's balance after the second withdrawal: $34.50 - $8.625 = $25.875
Third withdrawal: 1/4 of $25.875 = $6.46875 Stefano's balance after third withdrawal: $25.875 - $6.46875 = $19.40625
After the last withdrawal, Stefano has $19.41 in the account (rounded to the nearest cent).

find two consecutive integers whose product is 702
2 consecutive integers with the product of 702 are 27 • 26, or since the question doesn’t specify whether it should be positive or negative, it could also be (-27) • (-26)
Final answer:
The two consecutive integers whose product is 702 are found by solving the quadratic equation n² + n - 702 = 0. Factoring the equation leads to the integers 26 and 27.
Explanation:
To find two consecutive integers whose product is 702, we can denote the first integer as 'n' and the second as 'n+1'. Then the equation to represent their product is n(n+1) = 702. To find the value of 'n', we solve the quadratic equation
n² + n - 702 = 0.
Factoring the quadratic equation, we look for two numbers that multiply to -702 and add up to 1. We find that 26 and -27 meet these criteria. So the equation factors to (n + 27)(n - 26) = 0. The two possible values for 'n' are -27 and 26.
The two consecutive integers are 26 and 27 because -27 gives negative integers which do not result in a positive product of 702. Therefore, the two consecutive integers whose product is 702 are 26 and 27.
Given A= {(2,3),(5,1),(-3,-2),(0,3)} A is a subset of
A. N X R
B. R X N

The set A= {(2,3),(5,1),(-3,-2),(0,3)} is a subset of 'R x R', the cartesian product of Real numbers and Real numbers because both elements of all pairs in the set A are real numbers.
The given set A contains ordered pairs where each pair is constituted of two elements. An ordered pair is always in the form of (a, b) where 'a' is from the first set and 'b' is from the second set in a Cartesian product.
In the given subsets:
A. N X R(Cartesian product of Natural numbers and Real numbers)
B. R X N(Cartesian product of Real numbers and Natural numbers)
C. N X N(Cartesian product of Natural numbers and Natural numbers)
D. R X R(Cartesian product of Real numbers and Real numbers)
Looking at the subset A= {(2,3),(5,1),(-3,-2),(0,3)}, we can observe the first element of each pair in the set, we have 2, 5, -3, and 0. Negative numbers and zero are not natural numbers. Therefore it can't be a subset of 'N x R' or 'N x N'. But they are real numbers. Hence, it could be either 'R x N' or 'R x R'. However, if we look at the second element of each pair, we see that they are 3, 1, -2, and 3. Among these, -2 is a negative number and is not a natural number, but is a real number. Therefore, the set A must be a subset of 'R x R', which is the cartesian product of Real numbers and Real numbers.

According to the Triangle Inequality, the length of the longest side of a triangle must be less than the sum of the length of the other two sides. The two shortest sides of a triangle measure 3/10 and x + 1/5, and the longest side measures 3/2x
x has to equal 1. 3/10 + 1/5 = 1/2
the equation is now 1/2 + x = 1 1/2x
x = 1
1 1/2 = 1 1/2
Final answer:
The Triangle Inequality Theorem is applied to determine the range of values for x that would make the side lengths given form a valid triangle.
Explanation:
Understanding the Triangle Inequality Theorem
The Triangle Inequality Theorem states that in any triangle, the length of any side must be less than the sum of the other two sides. For the given question, we need to use this principle to analyze the side lengths. With the two shorter sides given as [tex]\( \frac{3}{10} \) and \( x + \frac{1}{5} \)[/tex], and the longest side given as [tex]\( \frac{3}{2}x \)[/tex], we can establish the inequality:
[tex]\( \frac{3}{2}x < \frac{3}{10} + \left( x + \frac{1}{5} \right) \).[/tex]
By solving this inequality, we can find the range of possible values for x that makes the configuration a valid triangle. This problem is an application of basic geometric principles and inequalities.
3/5 of a number is 30. What's the number?
To figure out the number we need to set up our equation to make more sense.
3/5 = 30/x (x is our missing number)
We know that what ever you do to the top of the fraction you can do to the bottom.
So if we multiply 3 x 10 we get 30.
Therefore to get the number we must multiply 5 by 10
5 x 10 = 50
So our answer and missing number is 50

Jade farm has 9 chickens,each of which laid 3 eggs. Jases farm has 4 horses. ednas farm has chickens which laid a total of 23 eggs. jase wonders whose chickens laid more eggs.
The answer is that Jade's chickens laid more eggs. Since Jade's farm includes 9 chickens, which each laid 3 eggs, multiply 9 and 3 and you get 27. Edna's farm has chickens which, in total, laid 23 eggs, leading to Jade's chickens with 27 eggs to be more than the eggs laid by Edna's chickens. :)
Answer:
Jade's chickens laid more eggs.
Step-by-step explanation:
Jade farm has number of chickens = 9
Each chickens laid number of eggs = 3
Total number of eggs on Jade's farm = 9 × 3 = 27 eggs
Ednas farm has chickens which laid a total of 23 eggs.
Difference between number of eggs = 27 - 23 = 4
Therefore, Jade's chickens laid 4 more eggs.
A Ferris wheel has 20 cars that are equally spaced around the circumference of the wheel. The wheel rotates so that the car at the bottom of the ride is replaced by the next car. By how many degrees does the wheel rotate?
The Ferris wheel rotates ______ ° between successive cars being at the bottom.
Answer:
The Ferris wheel rotates 18° between successive cars being at the bottom.
Explanation:
Angle inside a circle = 360°
No of cars in a Ferris wheel = 20
When the bottom of the ride is replaced by the next car, the angle rotated by Ferris wheel is same as the angle between two consecutive cars towards center of Ferris wheel.
Angle between two consecutive cars of Ferris wheel = 360/20 = 18°
The Ferris wheel rotates 18° between successive cars being at the bottom.
Final answer:
The Ferris wheel rotates by 18 degrees to move from one car to the next in sequence at the bottom of the wheel.
Explanation:
To determine by how many degrees the Ferris wheel rotates when one car is replaced by the next at the bottom, we need to consider the full rotation of the wheel. A full rotation of a circle is 360 degrees. Since there are 20 cars equally spaced around the circumference, we divide 360 degrees by the number of cars to find the rotation angle between successive cars.
The calculation is as follows:
360 degrees / 20 cars = 18 degrees
Therefore, the Ferris wheel rotates by 18 degrees between successive cars being at the bottom of the ride.
