Final answer:
The length of the arc of a circle with a radius of 3 and a central angle of 340 degrees is 17π. This is calculated by converting the angle to radians and finding the proportion of this angle to the full circle's circumference (2πr).
Explanation:
To find the length of the arc of a circle with a radius of 3 and a central angle of 340 degrees, we first need to understand that arc length (Δs) is proportional to the central angle when measured in radians. The circumference (Δ4) of a circle is given by the formula Δ = 2πr. Since there are 360 degrees in a complete circle, which corresponds to 2π radians, we can set up a proportion to solve for the arc length of the 340-degree angle.
The proportion will look like this:
Convert the central angle from degrees to radians by multiplying it by π/180.
340 degrees * π/180 = 340π/180 radians.
Use the ratio of the angle in radians to the entire circle in radians (2π) to find the arc length: Δs = (Angle in radians/2π) * Circumference.
Δs = (340π/180) / (2π) * 2π * 3.
Simplify to find the arc length Δs.
The final step yields the arc length for the given central angle and radius:
Δs = (340/360) * 2π * 3 = (17/18) * 2π * 3.
Therefore, the length of the arc is Δs = 17π.

Jenny's Bakery sells carrot muffins for $2.00 each. The electricity to run the oven is $120.00 per day and the cost of making one carrot muffin is $1.40. How many muffins need to be sold each day for the bakery to break even?
Answer:
D. 200 muffins
Step-by-step explanation:
Break even is a condition where the total production cost is same as the profit produced. In this question, the carrot muffin cost is $1.4 and sold at $2. Then the profit for every muffin should be: $2- $1.4= $0.6/muffin
The electricity cost is $120/day. Then to cover this cost, the muffin need to sold would be:
cost= muffin profit * muffin sold
$120= $0.6/muffin * muffin sold
muffin sold= $120 / ($0.6 / muffin)= 200 muffin

If Martha earns $6.50 per hour for babysitting, how much will she earn in: 1.5 hours? 2.5 hours? 3.5 hours?
Martha earns $6.50 per hour, so for 1.5 hours, she will earn $9.75; for 2.5 hours, she will earn $16.25; and for 3.5 hours, she will earn $22.75. We simply multiply her hourly wage by the number of hours to find the total earnings for each duration.
If Martha earns $6.50 per hour for babysitting, we can find out how much she will earn for different numbers of hours by multiplying her hourly rate by the number of hours worked.
For 1.5 hours: $6.50 * 1.5 = $9.75For 2.5 hours: $6.50 * 2.5 = $16.25For 3.5 hours: $6.50 * 3.5 = $22.75As a result:
Martha will earn $9.75 for 1.5 hours of babysitting.Martha will earn $16.25 for 2.5 hours of babysitting.Martha will earn $22.75 for 3.5 hours of babysitting.

B.x^3-x^2-13x+4
C.x^3+7x^2+11x+4
D.x^3+7x^2-13x+4
Final answer:
To simplify (x - 4)(x^2 + 3x - 1), use the FOIL method to distribute each term and combine like terms, resulting in x^3 - x^2 - 12x + 4 (option B).
Explanation:
To simplify the expression (x − 4)(x2 + 3x − 1), we need to use the distributive property, also known as the FOIL method, which stands for First, Outside, Inside, Last. We will multiply each term in the first binomial by each term in the second binomial.
Multiply the first terms: x * x2 = x3.Multiply the outside terms: x * 3x = 3x2.Multiply the inside terms: (-4) * x2 = -4x2.Multiply the last terms: (-4) * (3x) = -12x.Multiply the last terms: (-4) * (-1) = 4.Combine like terms:
x3 + 3x2 - 4x2 - 12x + 4
Simplify the expression by combining 3x2 and -4x2:
x3 - x2 - 12x + 4
Therefore, the simplified form of the expression is x3 - x2 - 12x + 4, which corresponds to option B.

Proportion is ________________
Proportion is a mathematical concept that describes the relationship between two or more quantities. It is often represented using ratios and can be used to solve for unknown values, scale measurements, and interpret data.
Explanation:Proportion is a mathematical concept that describes the relationship between two or more numbers or quantities. It is a way of expressing that one quantity is equal to another quantity, or that one quantity is a fraction or multiple of another quantity. Proportions can be represented using ratios, which compare the relative sizes of different quantities.
For example, if we have two ratios, such as 1:2 and 3:6, we can determine if they are proportional by cross-multiplying and checking if the products are equal. In this case, 1 × 6 = 2 × 3, so the ratios are proportional.
Proportions are used in many different areas of mathematics, such as solving for unknown values, scaling up or down, and interpreting data. They are also used in real-world applications, such as finding the missing side length of a similar triangle or calculating the unit price of a product.

How much money will Rachel have in her account in ten years
You need to have at least $100 in your checking account to avoid a low balance fee. You have $247 in your account, and you make withdrawals of $20 per week. What are the possible numbers of weeks that you can avoid paying the fee? Solve this problem using two different methods. PLEASE HELP
7 WEEKS is how long you can last.
First off, you need at least $100 in your account to avoid the fee and you currently have $247. With that being said, you're taking out $20 every week.
The first thing you can do would be to start at $147 (since that's $100 less than what you can use) and divide that by 20 (since that's what you're taking out every week) 147 / 20 = 7.35. That's 7 weeks because you have to round down to the nearest whole number.
Second What you can do to find how many weeks you can take this out by starting at $100 and adding $20 for every week. So 120, 140, 160, 180, 200, 220, 240. This also gives you 7.
You can take $20 out of your account for 7 WEEKS until you have to pay the low-balance fee.

Im totally lost! A sample from a refuse deposit near the Strait of Magellan had 60% of the carbon 14 of a contemporary living sample. Estimate the age of the sample ...?
Final answer:
The sample from the refuse deposit near the Strait of Magellan, with 60% carbon-14 remaining compared to a contemporary living sample, is estimated to be approximately 7777 years old, based on the known half-life of carbon-14 being 5730 years.
Explanation:
The age of a sample can be estimated using radiocarbon dating, which measures the decay of carbon-14 (14 C). Since the half-life of 14 C is known to be approximately 5730 years, we can use this information to estimate the age of the sample. Radiocarbon dating works on the principle that living organisms continually replenish carbon while alive, maintaining a constant level of 14 C relative to 12 C. When an organism dies, it no longer absorbs carbon, and the 14 C begins to decay at a known rate.
In the case of the refuse deposit near the Strait of Magellan, the sample had 60% of the carbon-14 of a contemporary living sample. To determine the age, we use the half-life formula, which is Time = Half-life / log2 (Starting amount / Remaining amount). Here, starting amount is 100% (contemporary living sample), the remaining amount is 60%, and the half-life is 5730 years.
So the calculation will be: Age of sample = 5730 / log2 (100/60). Calculating this, we get:
Age of sample = 5730 / log2 (1.6667)
Age of sample = 5730 / 0.737
Age of sample ≈ 7777 years
Thus, the sample from the refuse deposit near the Strait of Magellan is estimated to be approximately 7777 years old.

The sine of an angle in a right triangle is equal to the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse. ...?
Answer: The given statement is FALSE.
Step-by-step explanation: We are given to check whether he following statement is true or false :
"The sine of an angle in a right triangle is equal to the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse. "
Let us consider the right-angled triangle ABC as shown in the attached figure below.
With respect to acute angle C, we can see that
perpendicular, p = AB
base, b = BC
and
hypotenuse, h = AC.
We know that
sine of an angle in a right-angled triangle is equal to the ratio of the perpendicular to the base.
So, we must have
[tex]\sin \angle C=\dfrac{p}{h}\\\\\\\Rightarrow \sin \angle C=\dfrac{AB}{AC}.[/tex]
Since AB is the opposite side to angle C, not adjacent, therefore
sine of any angle in a right-angled triangle is the ratio of the length of the OPPOSITE SIDE to length of the hypotenuse.
Thus, the given statement is FALSE.
Final answer:
The statement is false; sine is the ratio of the opposite side to the hypotenuse, not the adjacent side to the hypotenuse.
Explanation:
The statement is false. In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite to the angle to the length of the hypotenuse, not the adjacent side to the hypotenuse. Therefore, the sine of angle A would be expressed as sin(A) = opposite/hypotenuse. The ratio of the adjacent side to the hypotenuse, on the other hand, defines the cosine of the angle, which is cos(A) = adjacent/hypotenuse.
The ratio of trumpet players to tuba players at a high school is 5:2 Which statement is true?
A.2/5 of the total tuba and trumpet players are tuba players.
B.The number of trumpet players is 2.5 times the number of tuba players.
C.There are 2 trumpet players for every 5 tuba players.
D.If there are a total of 100 trumpet and tuba players, 52 of them are tuba players.
The correct answer is Statement B: "The number of trumpet players is 2.5 times the number of tuba players." This statement accurately reflects the given ratio of trumpet players to tuba players.
Let's analyze each statement and determine which one is true:
A. "2/5 of the total tuba and trumpet players are tuba players."
To find out if this statement is true, we need to determine what portion of the total number of players are tuba players. Since the ratio of trumpet players to tuba players is 5:2, for every 5 + 2 = 7 players, 2 are tuba players. So, the proportion of tuba players is 2/7, not 2/5. Therefore, Statement A is false.
B. "The number of trumpet players is 2.5 times the number of tuba players."
According to the given ratio, for every 5 trumpet players, there are 2 tuba players. Thus, the number of trumpet players is indeed 2.5 times the number of tuba players. Therefore, Statement B is true.
C. "There are 2 trumpet players for every 5 tuba players."
This statement matches the given ratio, so it is true. However, it doesn't provide any additional information beyond what's already given in the initial problem.
D. "If there are a total of 100 trumpet and tuba players, 52 of them are tuba players."
To verify this statement, we can calculate the number of tuba players using the given ratio. Since the total ratio parts is 5 (trumpet) + 2 (tuba) = 7, and the total number of players is 100, we can find the number of tuba players as (2/7) * 100 = 28. Thus, Statement D is false.
Therefore, the correct answer is Statement B: "The number of trumpet players is 2.5 times the number of tuba players." This statement accurately reflects the given ratio of trumpet players to tuba players.
