Answer:
To the nearest hundredth, the density is 0.13 pounds per in^3
Step-by-step explanation:
Mathematically;
density = mass/volume
Thus;
density = 13 pounds/ 102 in^3
density = 0.1275
To the nearest hundredth, this is 0.13 pounds per in^3
In the Queen's Imperial State Crown, the ratio of diamonds to emeralds is 1:4. If the crown has 16 emeralds. Find how many diamonds will it have.
There are total 4 Diamonds.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Ratio of diamonds to emeralds = 1:4.
Total = 16 emeralds
let the common ratio be x.
Emeralds = 4x and Diamonds = x
So, 4x = 16
x= 4
Thus, number of diamonds
= 4
Hence, there are 4 diamonds.

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.

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 is 100 because you add 32 and 38 and equals 100 if you were to subtract you would have got 6%
Evelyn is buying a motorcycle that costs $14,000. The tax rate is 6.75%, and she plans to make a down payment of $1,500. The sales tax is
added before the down payment is applied. She is considering a three-year loan
Answer:
449.10
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

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.

Which describes the transformation that could have been applied to triangle ABC?

vertices decreased by 2 units.
O An isometric transformation could have been applied
because all of the vertices moved 2 units right and 2
units down.
A dilation could have been applied because all of the
vertices increased 2 units.
An isometric transformation could have been applied
because all of the vertices moved 2 units left and 2
units up.
Answer: I’m sorry im late, but the answer to your question should be B.
Step-by-step explanation: reason being is because the figure didnt grow/shrink like it would for a dilation so that gets rid of A. And C. And its not D. Because the dashed triangle is our original triangle not our new one so it would not make sense for it to go up and to the left. Thanks for coming to my ted talk
The image A'B'C' is formed by an isometric transformation because all of the vertices moved 2 units right and 2 units down, the correct option is B.
What is Transformation?Transformation is the process of changing the graph to a new graph by Rotation, Reflection, Translation, and Dilation.
Rotation is a type of transformation of an object on an x-y plane, when an object is turned clockwise or anticlockwise by a certain angle, the object is said to be rotated.
Reflection is creating a mirror image of the object, which is same in shape and size but only the coordinates have been changed.
Translation is moving the object, up, down, left or right on the coordinate axis.
Dilation is changing the size of the object, the original object is either enlarged or compressd by certain scale factor.
The object ABC shown in the image has coordinates A ( -2, 5), B (-5, -3), C(1, -3) and,
The image has the cooridnates A'(0,3), B'(-5,-3) , C'(3, -5).
The coordinates have been transformed by translation.
The transformation is an isometric transformation could have been applied because all of the vertices moved 2 units right and 2 units down.

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
