the answer is 1.981

Answer:

Standard form 1.981.

Step-by-step explanation:

Given  : 1 + 0.9 + 0.08 + 0.001 .

To find : What is standard form .

Solution : We have given 1 + 0.9 + 0.08 + 0.001 .

1 +[tex]\frac{9}{10}+\frac{8}{100}+\frac{1}{1000}[/tex].

We can see that 9 is at tenth place and 8 is at hundredth place and 1 is at thousandth place .

So,

To find the inverse of f(x) = 5x + 4, swap x and y to get x = 5y + 4, solve for y to get y = (x - 4)/5, which is the inverse.

With the given function f(x) = 5x + 4, we first replace f(x) with y to get y = 5x + 4. We then swap x and y to get x = 5y + 4. To solve for y, we subtract 4 from both sides, giving us x - 4 = 5y. Then, we divide both sides by 5, yielding (x - 4)/5 = y. Therefore, y = (x - 4)/5, which is the inverse of the function f(x).

The correct answer is y = 2x + 4.

The slope would be 2 and the y intercept would be 4. Now that we kbow this, we can determine that if we continuously put these points on a graph, it will make a horizontal line.

4 - 2/3x = -7 would be the equation to represent this.

He rode 6 blocks to the East than he rode 4 blocks to the West, so that means after he rode 6 blocks to the east he went backwards 4 blocks.

The equation is, 6-4=2 Because he only past 2 blocks from his home to arrive at the grocery store.

Bryce is 2 blocks past his house when he arrives at the grocery store.

To find out how many blocks past his house Bryce is when he arrives at the grocery store, we need to calculate the total distance he has traveled from his house to the grocery store. He rides 4 blocks west to school and then 6 blocks east to the grocery store. To find the total distance, we can subtract the distance traveled west from the distance traveled east: 6 blocks - 4 blocks = 2 blocks past his house.

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.

s - the number of the t-shirts;

h - the number of hats:

The system of equations:

s + h = 23

10 s + 12 h = 246

--------------------------

s = 23 - h

10 * ( 23 - h ) + 12 h = 246

230 - 10 h + 12 h = 246

2 h = 246 - 230

2 h = 16

h = 16 : 2

h= 8

s = 23 - 8

s = 15

Answer: The basketball team sold 15 t-shirts and 8 hats.

Step-by-step explanation:

The rental cost of the bike for 5.5 hours will be $55.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the bike rental company has determined that they will charge based on the nearest half-hour is $5.

The number of half-hours in 5.5 hours,

N = 5.5 / 0.5 = 11

The rental cost will be,

C = 11 x 5

C = $55

Therefore, the rental cost of the bike for 5.5 hours will be $55.

The complete question is given below.

The bike rental company has determined that they will charge based on the nearest half hour is $5. If Michael rented the bike for 5.5 hours how much would that cost?

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

move variable to the left side and change its sign

-3x+8=6y

Move constant to the right side and change its sign

-3x=6y-8

Divide both sides of the equation by -3

I think the x-intercept will be (16/3,0)

AND the y-intercept to be (0,4)

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.

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

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.

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.
