Answer:
In year 2030 the population is predicted to be 71.75 million
Step-by-step explanation:
* Lets explain how to solve the problem
- Using data from 2010 and projected to 2020, the population of
the United Kingdom (y, in millions) can be approximated by the
equation 10.0 y − 4.55 x = 581
- x is the number of years after 2000
- We need to know in what year the population is predicted to be
71.75 million
* Lets substitute the value of y in the equation by 71,75
∵ The equation of the population is 10.0 y - 4.55 x = 581
∵ y = 71.75
∴ 10.0(71.75) - 4.55 x = 581
∴ 717.5 - 4.55 x = 581
- Subtract 717.5 from both sides
∴ - 4.55 x = - 136.5
- Divide both sides by - 4.55
∴ x = 30
∵ x represents the number of years after 2000
∵ 2000 + 30 = 2030
∴ In year 2030 the population is predicted to be 71.75 million
Final answer:
The population of the United Kingdom is predicted to be 71.75 million in the year 2030, calculated by substituting the given population value into the equation and solving for the year.
Explanation:
To find the year in which the population of the United Kingdom is predicted to be 71.75 million, you can use the given equation 10.0y - 4.55x = 581. Here, x is the number of years after 2000, and y is the population in millions.
First, substitute y with 71.75:
10.0(71.75) - 4.55x = 581717.5 - 4.55x = 5814.55x = 717.5 - 5814.55x = 136.5x = 136.5 / 4.55x = 30Now, add the number of years, x, to the base year, 2000:
2000 + 30 = 2030Therefore, the population of the United Kingdom is predicted to be 71.75 million in the year 2030.

Write an algebraic expression for the phrase.
the sum of b and 11
a. b – 11
b. b/11
c. b + 11
d. 11b
Final answer:
The algebraic expression for the phrase 'the sum of b and 11' is 'b + 11'. This expression represents adding 'b' to '11', and addition is commutative, which means it could also be written as '11 + b'. So the correct option is c.
Explanation:
The phrase 'the sum of b and 11' represents an algebraic expression where sum refers to the addition of two terms. When we talk about the sum of two algebraic expressions, we use the plus sign (+) to denote the operation. Therefore, for the given phrase 'the sum of b and 11a', the algebraic expression is b + 11.
It’s important to keep in mind that in algebra when we want to indicate that one term is multiplied by another, we often place them next to each other without any symbol, which is known as concatenation. And because addition is commutative, we could also write this expression as 11 + b, and it would mean the same thing.
Also worth mentioning is the distinction between the expression 'b - 11' (which means 'b' subtracted by '11') and 'b/11' (which means 'b' divided by '11'). These are different operations and would not correctly represent the phrase we were given to translate into an algebraic expression.

the square of a whole number is between 200 and 250. the number must be between
Step-by-step explanation:
square of 15 = 225
The Number must be between 14 and 16
Answer:
The number will lie between 14 and 16.
Step-by-step explanation:
If the square of a whole number is between 200 and 250 then the inequality formed will be
200 < x² < 250
where x is a whole number.
Now we will simplify this inequality.
[tex]\sqrt{200}<\sqrt{x^{2} } <\sqrt{250}[/tex]
14.14 < x < 15.81
By approximation, 14 < x < 16
Therefore, the number must lie between 14 and 16.
If Carl was born in January 1931 how old is he now?

What is the product? negative 9 x (5 minus 2x)
Answer:
18x²-45x
Step-by-step explanation:
Final answer:
To find the product of negative 9 and (5 minus 2x), use the distributive property, resulting in -45 + 18x.
Explanation:
The product of negative 9 and (5 minus 2x) can be found by applying the distributive property. This property states that a number multiplied by a sum or difference in parentheses is equivalent to the number multiplied by each term inside the parentheses separately, and then summing the results. So, the product will be:
Negative 9 multiplied by 5, which gives -45.
Negative 9 multiplied by -2x (note the two negatives make a positive), which gives 18x.
Combining these two products, we get the final answer, which is -45 + 18x.

What is the slope of a line perpendicular to the line whose equation is y=2x + 5?
slope=-1
slope =-1/2
slope=-2
Answer:
-1/2
Step-by-step explanation:
For a line to be parallel, they must be equal, for it to be prependicular, the slope must have an opposite value and be over the value.
Answer:
[tex]\frac{-1}{2}[/tex]

We are given a line [tex]y=2x + 5[/tex]
On comparing with general form
m = 2
Let n be the slope of line perpendicular to the line [tex]y=2x + 5[/tex]
The product of the slopes of perpendicular lines is -1
So,[tex]m \times n = -1[/tex]
[tex]2 \times n = -1[/tex]

Use the quadrant system to find the area of the polygon
Answer:
The area of the polygon is 64 units²
Step-by-step explanation:
* Lets explain how to solve the problem
- The polygon has 5 sides and 5 vertices
- To find its area by easy way split it into two trapezoid by a horizontal
line y = 1
- The vertices of trapezoid (1) are (-5 , 1) , (4 , 1) , (-5 , 5) , (0 , 5)
- The vertices of one of the parallel bases are (-5 , 1) , (4 , 1)
- The length of this base = 4 - (-5) = 4 + 5 = 9 units
- The vertices of the other parallel bases are (-5 , 5) , (0 , 5)
- The length of this base = 0 - (-5) = 0 + 5 = 5 units
- The length of its height = 5 - 1 = 4 units
- The area of the trapezoid = 1/2 (b1 + b2) × h
∴ Area of trapezoid 1 = 1/2 (9 + 5) × 4 = 28 units²
- The vertices of trapezoid (2) are (4 , 1) , (-5 , 1) , (-5 , -5) , (-2 , -5)
- The vertices of one of the parallel bases are (4 , 1) , (-5 , 1)
- The length of this base = 4 - (-5) = 4 + 5 = 9 units
- The vertices of the other parallel bases are (-5 , -5) , (-2 , -5)
- The length of this base = (-2) - (-5) = -2 + 5 = 3 units
- The length of its height = 1 - (-5) = 1 + 5 = 6 units
∴ Area of trapezoid 1 = 1/2 (9 + 3) × 6 = 36 units²
∵ Area of the polygon = Area trapezoid (1) + Area trapezoid (2)
∵ Area trapezoid (1) = 28 units²
∵ Area trapezoid (2) = 36 units²
∴ Area of polygon = 28 + 36 = 64 units²
∴ The area of the polygon is 64 units²

The final amount of money was $50, they spent half of what they collected on canned foods, so 50 x 2 = 100.
They collected a total of $100.
Let the amount Eric collected = X
Charlotte collected 3 times as much minus $20, writing this as an equation you get 3x-20.
Now you have Eric plus Charlotte = $100:
x + 3x-20 = 100
Combine like terms:
4x-20 = 100
Add 20 to both sides:
4x = 120
Divide both sides by 4:
x = 120/4
x = 30
Eric = X = $30
Charlotte = 3x-20 = 3(30) - 20 = 90 -20 = $70
Answer:
40
Step-by-step explanation:
the the answer is 40 because if you do 40 * 3 to get 120 and if you minus 20 then you get a hundred in a hundred divided by 2 equals 50
what you do is you do 50 * 2 but you got to 100 then you add 20 which gives 220 then you ÷ by 3

Find the area of the regular hexagon whose side length is 1 cm.
The area of the regular hexagon is approximately 2.598 cm².
Finding the Area of a Regular Hexagon
To find the area of a regular hexagon with a side length of 1 cm, we can use the formula for the area of a regular polygon:
Area = (3√3 / 2) × s², where s is the side length.
Given that the side length ( extbf{s}) is 1 cm:
Square the side length: 1² = 1 cm²
Multiply by (3√3 / 2): (3√3 / 2) × 1 cm² ≈ 2.598 cm²
Thus, the area of the regular hexagon is approximately 2.598 cm².
i need help with a math problem right now it says A car rental agency advertised renting a car for $27.95 per day and $0.28 per mile. If David rents his car for 3 days, how many whole miles can he drive on a $200 budget
Answer:
David would have to drive for 415 miles before he reaches his $200 budget.
Step-by-step explanation:
It cost $27.95 per day to rent a car and he is only renting it for 3 days. ($27.95 x 3 = $83.85 for all three days). When you subtract $83.85 from his $200 budget you get, $116.15. It is .28 cents for each mile. Next you divide $116.15 by .28 cents to equal 414.82 miles. Round the miles to a whole number to get 415 miles.
