what is the poorest country in the world
The poorest countries in the world are primarily in Africa and Asia, according to the World Bank's 2020 report. These countries struggle with governance issues, economic struggles, conflict, and other socio-economic problems, inhibiting their growth. The Democratic Republic of Congo, despite its wealth in resources, significantly exemplifies this due to political instability.
Explanation:According to the World Bank rankings, many of the poorest countries globally share common traits such as governance failures, economic struggles, and conflicts. These factors, among others, inhibit economic growth and improvement across sectors such as healthcare, education, and infrastructure.
As detailed in the World Bank's 2020 report, the ten lowest income countries include nations primarily located in Africa and Asia. Due to various socioeconomic issues, these countries have low gross national income (GNI) per capita, with notable examples including Afghanistan, Ethiopia, and Zimbabwe.

Write parametric equations of the line 2x-y=3
Answer: The required parametric equation is y=2t-3.
Step-by-step explanation:
Since we have given that
2x+-y=3
We need to rewrite in parametric equation:
The parametric equation is written as
[tex]f(x)=y=at+b[/tex]
So, Arranging the given equation in the above equation, we get
[tex]2x-y=3\\\\2x-3=y\\\\f(x)=y=2x-3[/tex]
And then put x = t, to get the exact parametric form.
Hence, the required parametric equation is y=2t-3.

hey can you please help me posted picture of question
A shop sells 200 chocolate vanilla and strawberry ice creams 45% of the ice cream sold are vanilla and 30% are strawberry how many chocolate ice creams are sold
Final answer:
The answer explains how to calculate the number of chocolate ice creams sold in a situation where vanilla and strawberry ice creams are already accounted for.
Explanation:
The total number of ice creams sold is 200.
45% are vanilla ice creams. 45% of 200 is 90.
30% are strawberry ice creams. 30% of 200 is 60.
To find the number of chocolate ice creams sold:
Chocolate ice creams = Total ice creams - (Vanilla ice creams + Strawberry ice creams)
Chocolate ice creams = 200 - (90 + 60)
Chocolate ice creams = 200 - 150 = 50
Therefore, 50 chocolate ice creams are sold.

The blades on a wind turbine trace a circular path with radius 100 feet. Suppose the turbine spins at 20 revolutions per minute. What is the linear velocity, in miles per hour (1 mile equals 5,280 feet), of a point on the tip of a blade? Round the answer to the nearest tenth.
The linear velocity of a point on the tip of a blade on a wind turbine is approximately 0.05 miles per hour.
Explanation:To find the linear velocity of a point on the tip of a blade on a wind turbine, we need to convert the rotational speed to linear speed. The formula to do this is linear speed = radius × angular speed. In this case, the radius is 100 feet and the turbine spins at 20 revolutions per minute. First, we convert the revolutions per minute to radians per second by multiplying by 2π/60. Then, we multiply the angular speed by the radius to find the linear speed.
Angular speed = 20 revolutions per minute × 2π/60 = 20π/60 = π/3 radians per second
Linear velocity = 100 feet × π/3 = 100π/3 feet per second
Finally, to convert the linear velocity to miles per hour, we divide by 5280 (since 1 mile equals 5280 feet).
Linear velocity = (100π/3) / 5280 ≈ 0.05 miles per hour

Calculate the slope of a line that intersects points (6,2) and (-4,-3).
A. 1/2
B. 2/3
C. 4/5
D. 7/8
The slope of the line passing through the points (6,2) and (-4,-3) is calculated using the slope formula (y2 - y1) / (x2 - x1), resulting in a slope of 1/2.
To calculate the slope of a line that intersects points (6,2) and (-4,-3), we use the slope formula, which is (change in y) / (change in x), or (y2 - y1) / (x2 - x1). Here, we consider point 1 to be (6,2) and point 2 to be (-4,-3).
Using the formula:
y2 = -3y1 = 2x2 = -4x1 = 6Substituting the values into the formula gives us the following calculation:
Slope = (-3 - 2) / (-4 - 6)
Slope = (-5) / (-10)
Slope = 1/2
Therefore, the correct answer is A. 1/2.
You planted 488 acres of corn last season. you sold all your corn: 8,120 bushels in August and 64,100 bushels in September. what is your yield pet acre, rounded to the nearest bushel per acre
Answer:
There will be approx 148 bushels in per acre.
Step-by-step explanation:
You planted 488 acres of corn last season.
you sold all your corn: 8,120 bushels in August and 64,100 bushels in September.
Total bushels = [tex]8120+64100=72220[/tex]
Now, this amount of bushels were in 488 acres of land.
So, per acre will contain = [tex]72220/488=147.99[/tex]≈ 148 bushels
Hence, there will be approx 148 bushels in per acre.

the equation d=1/2n (n-3) gives the number of diagonals D for polygon with n sides. use this equation to find the number of sides n for a polygon that has 65 diagonals
Answer: 13
Step-by-step explanation:
Given : The equation [tex]d=\dfrac{1}{2}n(n-3)[/tex] gives the number of diagonals d for polygon with n sides.
To find the number of sides n for a polygon that has 65 diagonals, we substitute the value of d= 65 in the given equation, we get
[tex]65=\dfrac{1}{2}n(n-3)[/tex]
Multiply 2 on both sides , we get
[tex]n(n-3)=130\\\\\Rightarrow\ n^2-3n-130=0\\\\\Rightarrow\ n^2-13n+10n-130=0\\\\\Rightarrow\ n(n-13)+10(n-13)=0\\\\\Rightarrow\ (n-13)(n+10)=0\\\\\Rightarrow\ n= -10\ or\ n= 13[/tex]
But number of sides cannot be negative, so the number of sides n for a polygon that has 65 diagonals = 13

Below is the table of values of a function. Write the output when the input is
n
input 1 4 9 n
output 5 8 13 ?
What is the last output ?
Answer:
n + 4
Or 20
Step-by-step explanation:
Depends on how you see it the answer could be n´+4 since that´s how the function is working, and almost all of the time the independent clauses are actually independent and do not follow any progression.
But if there is a progression in the input, we can see that they are adding up uneven numbers to the input, so first we added 3, then we added 5, and last we should add 7: so the input would be 7+9= 16, the input in the forth spot should be 17, and the output should be 20.
