We are told that Christine has 9 shinning rings, and that if 5 of them are gold, how many are not gold?
Let the number of the rings that are not gold be n,
Since she has 9 rings and 5 are gold, then the numbers that are not gold which is n becomes
\(9\text{ shinning rings - 5 gold rings}\)So,
\(n=9-5\)If we bring -5 to meet n, then the minus sign becomes a plus sign, we have
\(n+5=9\)Hence, the answer is option D
\(n+5=9\)Solve 3x-1=10

What is Angles?
In Euclidean geometry, an angle is the shape created by two rays that share a terminus and are referred to as the angle's sides and vertices, respectively. The plane that contains the rays contains the angles created by two beams. The meeting of two planes might also result in an angle. Dihedral angles are what these are.
We can write
(6x + y) = (x + 5y)
[By corresponding angles]
6x + y = x + 5y
6x - x = 5y - y
5x = 4y
x = 4y/5
Now by linear pair
4x + (6x + y) = 180
4x + 6x +y = 180
10x + y = 180
By putting the value of x
10(4y/5) + y = 180
8y + y = 180
9y = 180
y = 180/9
y = 20°
Putting the value of y in x we get
x = 4(20) / 5
x = 4(4)
x = 16°
Hence, value of x = 16° and y = 20°

The impact on Carns’s income from eliminating the Small Tools Division would be: Multiple Choice
The impact on Carns Company's income from eliminating the Small Tools Division would be a decrease of $1,209,000.
To determine the impact on Carns Company's income from eliminating the Small Tools Division, we need to consider the avoidable costs associated with the division.
The avoidable costs include all of the variable costs of the division and a portion of the fixed costs that are specifically related to the Small Tools Division. In this case, the variable costs of the division are $1,295,000, and $119,000 of the fixed costs are avoidable.
To calculate the impact on income, we subtract the avoidable costs from the loss reported by the division:
Impact on income = Loss - Avoidable costs
Impact on income = $205,000 - ($1,295,000 + $119,000)
Impact on income = $205,000 - $1,414,000
Impact on income = -$1,209,000
The negative sign indicates a decrease in income.

The total cost of an animal is the cost of food and the other expenses. Let
the other expenses total $15,000 a week. Food costs $7 a pound.
Write an expression to show how much it costs per week to keep the baby
animal where x is the number of pounds one adult eats in a day. Simplify
your expression
Please help???
Answer:
First, let's establish a few facts based on your question:
1. The food costs $7 per pound.
2. An adult animal eats x pounds of food per day.
3. There are other costs totaling $15,000 per week.
4. We are assuming a 7-day week.
Now, let's write an expression for the total cost of keeping an adult animal for one week.
The food cost for one day for an adult animal is 7x dollars (because the animal eats x pounds of food per day, and each pound costs $7).
So, an adult animal's food cost for one week (7 days) is 7x * 7 dollars.
Plus the other expenses of $15,000 per week, the total cost for one week becomes:
7x * 7 + 15,000
This simplifies to:
49x + 15,000
This expresses the total cost of keeping an adult animal for one week.
The baby animal usually eats less than an adult. We can't establish an exact formula if we don't have a specific proportion or ratio. Let's assume a baby animal eats half the amount of an adult animal (0.5x); you could adjust this as per the actual ratio for your specific animal.
So, a baby animal's food cost for one day is 7*0.5x dollars.
A baby animal's food cost for one week (7 days) is 7*0.5x * 7 dollars.
So, adding the other expenses of $15,000 per week, the total cost for one week becomes:
7*0.5x * 7 + 15,000
This simplifies to:
24.5x + 15,000
This would be the expression for the total cost of keeping a baby animal for one week, assuming it eats half the amount of an adult. You can adjust the 0.5 factor to match your specific animal's actual food consumption ratio of the baby to the adult.

The number of people in the set C ∩ D (customers who purchased both cats and dogs) is obtained by adding the overlap of D and C (3) with the overlap of all 3 circles (1), resulting in a total of 4 individuals.
The correct answer is 4.
To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to analyze the overlapping regions in the Venn diagram.
Given information:
- Circle C (cats): 15
- Circle D (dogs): 21
- Circle F (fish): 12
- Overlap of C and F: 2
- Overlap of F and D: 0
- Overlap of D and C: 3
- Overlap of all 3 circles: 1
- Number outside of circles: 14
To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to consider the overlapping region between circles C and D.
From the information given, we know that the overlap of D and C is 3. Additionally, we have the overlap of all 3 circles, which is 1. The overlap of all 3 circles includes the region where customers have purchased cats, dogs, and fish.
To calculate the number of people in the set C ∩ D, we add the overlap of D and C (3) to the overlap of all 3 circles (1). This gives us 3 + 1 = 4.
Therefore, from the options given correct one is 4.

3 6 9 12 15 18 21 24 27 30 is odd or even numbers?
Answer: Half of them are even and half of them are odd.
Step-by-step explanation:
The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.
The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.
Therefore, out of the given numbers, half of them are even and half of them are odd.

Triangle ABC with vertices at A(-1,-1), B(1,1), C(0,1) is dilated to create triangle A’B’C with vertices at A’(-3,-3), B’(3,3), C’(0,3) determine the scale factor used.
A. 1
B. 1/2
C. 3
D. 1/3
The scale factor used in the dilation is 3.
First, the distance between points A and B in triangle ABC is:
AB = √[(x₂ - x₁)² + (y₂ - y₁)²]
AB = √[(1 - (-1))² + (1 - (-1))²]
AB = √[(2)² + (2)²]
AB = √[4 + 4]
AB = √8
The distance between points A' and B' in triangle A'B'C' is:
A'B' = √[(x₂' - x₁')² + (y₂' - y₁')²]
A'B' = √[(3 - (-3))² + (3 - (-3))²]
A'B' = √[(6)² + (6)²]
A'B' = √[36 + 36]
A'B' = √72
The scale factor can be determined by dividing the corresponding side lengths:
Scale factor = A'B' / AB
Scale factor = √72 / √8
Scale factor = (√(72/8))
Scale factor = √9
Scale factor = 3
Therefore, the scale factor used in the dilation is 3.

how many pattern blocks rhombuses would 4 triangles create
Four triangles can create a set of pattern blocks that includes a total of four rhombuses.
To understand why, it's essential first to understand what pattern blocks are. Pattern blocks are shapes that are commonly used in early childhood education to teach math concepts like geometry, spatial reasoning, and fractions. They come in different shapes, including triangles, squares, hexagons, trapezoids, and rhombuses.
To create a set of pattern blocks using triangles, one can use four equilateral triangles with the same side length. When these triangles are arranged together, they form a larger equilateral triangle, as each external side of each small triangle connects to a side of another triangle. This larger equilateral triangle can then be divided into four smaller rhombuses by using two diagonals (lines connecting opposite corners) to form a "X" shape. Each of these four smaller rhombuses is made up of two adjacent triangles and forms a diamond shape. Therefore, it can be said that four equilateral triangles can form a set of four rhombuses within an equilateral triangle pattern block set.

Rewrite y=2(1.06)9t in the form y=a(1+r)t or y=a(1−r)t to determine whether it represents exponential growth or exponential decay. Round a and r to the nearest hundredth if necessary.
The function is an exponential growth function
How to determine the type of the functionThe function is given as
y=2(1.06)^9
We can begin by rewriting the given equation as:
y = 2 * 1.06t
So, we have
y = 2 * (1 + 0.06)^t
Now we can see that the equation is in the form y = a*b^t,
where a = 2 and b = 1.06^9
This equation represents exponential growth because the base of the exponent, b = 1.06, is greater than 1.
We can re-write it in the form y = a(1+r)t,
we can find the value of r by subtracting 1 from 1.06 which is 0.06 and the value of a is 2.
so we have y = 2(1+0.06)^t
So, the equation represents exponential growth with a = 2 and r = 0.06

Yes or no because the side lengths in the image and pre-image are different or th same
Answer: No. The triangles are not congruent because their side lengths are different.

NO. Clare is wrong because, after dilation, the corresponding side lengths of triangle ABC (pre-image) and triangle A'B'C' (image) are different. They are not congruent.
Recall:
After an figure is dilated, the pre-image which is the original image would have the same shape as the image (new image).Two figures with the same shape but different sizes are similar and areTwo images that are similar will have corresponding side lengths that are proportional to each other.Thus, after dilation, triangle ABC and triangle A'B'C' cannot be congruent to each other. They are rather similar to each other because the side lengths of the image and pre-image will definitely be different from each other.

Whenever Deven and Laura owe each other money, they "pay" each other using stickers. They've agreed that a Harry Potter sticker is worth 49 dollars and a Twilight sticker is worth 35 dollars. They can even use stickers as "change" if one person overpays the other. For example, if Deven owes Laura 189 dollars, he can give her 6 Harry Potter stickers ($6 \cdot 49 = 294$ dollars), and she can return 3 Twilight stickers ($3 \cdot 35 = 105$ dollars). This trade is like a transfer of $294-105=189$ dollars. What is the smallest positive debt, in dollars, that can be paid off using sticker trading?
The smallest positive debt that can be paid off using sticker trading is $7$ dollars.
To find the smallest positive debt that can be paid off using sticker trading, we need to consider the values of the stickers (in dollars) and find the smallest positive amount that can be reached through a combination of these values.
Given that a Harry Potter sticker is worth $49 and a Twilight sticker is worth $35, we can approach this problem using the concept of the greatest common divisor (GCD) of these two values.
The GCD of $49$ and $35$ is $7$. This means that any multiple of the GCD can be represented using these sticker values.
In other words, any positive multiple of $7$ dollars can be paid off using sticker trading.
Therefore, the smallest positive debt that can be paid off using sticker trading is $7$ dollars.

The most general solution to the associated homogeneous differential equation is y=x/2-1/4
How will you solve this equation?C=0
dy/dx+2y=x
Use the formula:
\(\int\ \,xe^(2x)dx=e^(2x)\)((x/2−1/4).
We know that a linear differential equation is written in the standard form:
y' + a(x)y = f(x)
we get that: a(x)=2 and f(x)=x.
We know that the integrating factor is defined by the formula:
u(x)=\(e^{\int\ \, a(x) dx}\)
⇒ u(x)=\(e^{∫ 2 dx}\)= \(e^{2x}\)
The general solution of the differential equation is in the form:
y=\frac{ ∫ u(x) f(x) dx +C}{u(x)}
⇒ y=\frac{\(e^{2x}\)· x dx + 0}\({e^{2x}}\)
y=\frac{\(e^{2x}\) (x/2-1/4)\(}{e^{2x}\)
y=x/2-1/4
Hence, the most general solution to the associated homogeneous differential equation is y=x/2-1/4.
