In 2010, the population of China was around 1.400,000,000 and growing
at a rate of 1.65% per year. What should the population be this year?*
Answer:
1423100000
Step-by-step explanation:
1.65% of 1.4 billion is 23,100,000. Knowing this you just add the two numbers together to find what an extra 1.65% of people being added to the population would result in.
The current population of China is 1,423,100,000 using the compound rate of increment method.
What is a compound rate of increment?The compound rate of increment is a type of increment that is compounded after time period it is said to be compounded. After that particular period, the increment is calculated and then added with the primary number. For the next duration, the increment is calculated on the sum.
Given, the total of population of China in 2010 was (P) = 1,400,000,000.
The rate of increase of population is (r) = 1.65%
Duration (n) = (2022 - 2010) years = 12 years.
Therefore, the total of population of China in 2022 (S)
= P(1 + r)ⁿ
= 1,400,000,000(1 + 1.65/100)¹²
= 1,400,000,000(1 + 0.0165)¹²
= 1,400,000,000(1.0165)¹²
= 1,423,100,000
Therefore, the population of China in 2022 is 1,423,100,000.

Jenny calculates that this is a percentage increase of 19%
Is Jenny's percentage correct?
PLZ SHOW WORKING OUT
Answer:
Jenny's percentage isn't correct
Step-by-step explanation:
You'd have to divide first:
38 / 32 = 1.1875 = (rounded) 1.19%
The percentage increase is 1.19%
Answer:
the percentage is 100 because you add 32 and 38 and equals 100 if you were to subtract you would have got 6%

I don’t know if I am supposed to substitute the x variable in f(x) or leave the f(x) the same.
Answer:
I believe the answer would be B.
Step-by-step explanation:
The x on the left side of the chart is what you will plug into the function. For example for 0.
f(0) = [tex]\sqrt{100-0}[/tex]
So you just plug in the x into the function.
Solve 4a= 12 jvyctxychvuvu
Answer:
The answer is a = 3
Step-by-step explanation:
Because 4 * a = 12 you can also reverse it and make it 12 / 4 = a, and 12 / 4 = 3, so that is your answer.
Use the quadratic formula to find the solutions to the equation.
3x2 - 10x + 5 = 0
Answer: A
Step-by-step explanation:
3x² - 10x + 5 = 0
a = 3 b = -10 c = 5
Δ = b²- 4ac = 100 - 4.3.5 = 40 > 0 => have 2 solutions
=> x = [tex]\frac{10+\sqrt{40} }{6}[/tex] or x = [tex]\frac{10-\sqrt{40} }{6}[/tex]
[tex]x= \frac{10\pm \sqrt{40} }{6}[/tex] is the solution to the given quadratic equation.
What is quadratic equation?
Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = [tex]ax^{2} +bx+c[/tex] = 0 where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where 'a' is called the leading coefficient and 'c' is called the absolute term of f (x).
Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]
Given quadratic equation
[tex]3x^{2} -10x+5=0[/tex]
a = 3, b = -10, c = 5
Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]
[tex]x= \frac{-(-10)\pm \sqrt{(-10)^{2} -4(3)(5)} }{2\times3}[/tex]
⇒ [tex]x= \frac{10\pm \sqrt{100 -60} }{6}[/tex]
⇒ [tex]x= \frac{10\pm \sqrt{40} }{6}[/tex]
Hence, [tex]x= \frac{10\pm \sqrt{40} }{6}[/tex] is the solution to the given quadratic equation.

The probability that the selected student is a sophomore given that he is a boy will be 5/12.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
we need to select the probability that the selected student is a sophomore given that he is a boy;
In this case;
P(B) = P(boy)
P(A) = P(sophomore)
The total number of students which is 12 + 18 = 30
From the table;
P(B) = 12/30
P(A n B) = 5/30
So;
P(A|B) = 5/30 / 12/30
= 5/30 x 30/12 = 5/12
Hence, the probability that the selected student is a sophomore given that he is a boy will be 5/12.

Given that the radius of the circle is
2 yd.
Step-by-step explanation:
Area of first triangle = 1/2bh
the base of the triangle = the radius of the semi-circle = 2yd
height = 5yd
Area = 1/2(5yd)(2yd)
A = 5yd(yd)
A = 5y^2d^2 squared units.
since the second triangle also has the same dimensions as the first triangle
hence:
Area of the second triangle = 5y^2d^2 squared units.
Area of semi-circle = πr^2
Area = π(2yd)^2
A = 4πy^2d^2 squared units
Find three consecutive integers such that the sum of twice the second and four times the third is twenty-five more than the first?
Answer:
3, 4, 5
Step-by-step explanation:
Three consecutive integers means that
[tex]X_1, X_2 = X_1 + 1, X_3 = X_2 + 1[/tex]
The sum of twice the second and 4 times the third is 25 times the first number
[tex]X_1 + 25 = 2X_2 + 4X_3\\X_1 + 25 = 2(X_1 + 1) + 4(X_1 + 2)\\X_1 + 25 = 2X_1 + 2 + 4X_1 + 8\\X_1 + 25= 6X_1 + 10\\5X_1 = 15\\X_1 = 3\\X_2 = 4, \\X_3 = 5[/tex]
Who started the problem correctly? The problem form is (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
Answer:
Shane started the problem correctly
Step-by-step explanation:
We are given problem (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
We need to find who started the problem correctly.
The problem should be started by converting the mixed fraction into improper fraction i,e
[tex]-5-(-1\frac{3}{4})\\=-5-(-1-\frac{3}{4} )\\=-5-(-\frac{7}{4})[/tex]
Now we will solve bracket by multiplying -1 with term inside the bracket i.e
[tex]=-5+\frac{7}{4}[/tex]
[tex]= \frac{-13}{4}[/tex]
Let's compare both the procedures now:
Mariah:
[tex](-5) + 1 - \frac{3}{4}[/tex]
[tex]=(-5) - \frac{1}{4}[/tex]
[tex]=\frac{-21}{4}[/tex]
Therefore, Mariah did not start the problem correctly.
Shane:
[tex](-5) + 1 + \frac{3}{4}[/tex]
[tex]= -5 + \frac{7}{4}[/tex]
[tex]= \frac{-13}{4}[/tex]
Therefore, Shane started the problem correctly.

Which angle in ABC has the largest measure?
Answer:
Angle B
Step-by-step explanation:
Angle B because the measure of angle B is 12 . Angle A has a measure of 7 and angle C has a meausre of 10 which both measures of the angles are less than angle B. Think of it like this... 17 people (7+10) went to a Bakery. There were only 7 cupcakes and 10 sweet potato pies. To start with there were 35 cupcakes and 35 sweet potato pies. 7 people ordered cupcakes and 10 people ordered sweet potato pie. There were 18 left of the 2 deserts. 18 is greater than 7 and 10. That´s why angle B is the angle that has the largest measure. 12 is greater than 7 and 10. If there were only 7 milkshakes left and 10 people wanted a milkshake, only 7 people would be able to get a milkshake. 3 people wouldn´t be able to get a milkshake
So angle B is the correct answer.
