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.

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.

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%

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.

Answer: angle b

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.

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.

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.

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

Step-by-step explanation:

Her monthly payment, if she is considering a three-year loan is $373.47

Given the cost of the motorcycle to be $14000

If the tax rate is 6.75%, the total cost plus tax is expressed as:

Final cost = 14000+(0.0675 * 14000)

Cost of motorcycle = 14000 + 945

Cost of motorcycle = $14945

If she plans to make a down payment of $1,500 before the sales tax is applied, then;

Balance = 14945 - 1500

Balance = $13,445

If she considers  a three-year loan, her monthly payment will be ;

Monthly payment = 13,445/36

Monthly payment = $373.47

Hence her monthly payment if she is considering a three-year loan is $373.47

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.

Answer:

I believe it is A

Step-by-step explanation:

When you subtract z1 from z2, you get 2-4i, which on the graph is point A.

Point A represents 2-4i in the graph given. Therefore, option (1) is the correct answer.

Given that, [tex]z_{1}=5-2i[/tex] and [tex]z_{2}=3+2i[/tex].

We need to find the value of [tex]z_{1}-z_{2}[/tex].

A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane.

Now, [tex]z_{1}-z_{2}[/tex]=5-2i-(3+2i)

=5-2i-3-2i

=2-4i

Here, 4i is the imaginary and 2 real numbers.

Point A represents 2-4i in the graph given. Therefore, option (1) is the correct answer.
