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.

Answer

23 and 24.

Explanation

let the first integer be x.

The next integer would be x + 1

Now form the equation

x + (x+1) = 46

x + x + 1 = 46

2x + 1 = 46

2x = 46 - 1

x = 45

x = 22.5        This is not an integer.

Since the question is asking for the least possible integer, unless we use 23 ≅22.5

The first integer been 23, the other one would be (23 + 1) = 24.

The least possible pair would be 23 and 24.

Celeste is making fruit baskets for her service club, and she is not following the specific ratio but using a similar ratio of apples to oranges in her baskets.

Celeste is making fruit baskets for her service club, and the directions say to fill the boxes using 5 apples for every 6 oranges. However, Celeste is filling her baskets with 2 apples for every 3 oranges. To determine if Celeste is following the directions, we can compare the ratio of apples to oranges in her baskets with the ratio specified in the directions.

In the directions, the ratio of apples to oranges is 5 apples: 6 oranges, which can be simplified to 5/6. In Celeste's baskets, the ratio of apples to oranges is 2 apples : 3 oranges, or 2/3.

To compare these ratios, we can find the least common multiple (LCM) of the denominators (6 and 3), which is 6. Then, we can convert both ratios to have the same denominator using equivalent fractions:

5/6 * 1/1 = 5/6 and 2/3 * 2/2 = 4/6.

Since 4/6 is less than 5/6, Celeste is not following the directions exactly. However, she is still using a similar ratio of apples to oranges in her baskets.

The cost of one apple is 0.5, option C is correct.

Two or more expressions with an Equal sign is called as Equation.

Let A represents cost of one apple and B represents cost of one banana

Three apples and two bananas cost 2.00

3A+2B=2...(1)

Four apples and four bananas cost 3.00.

4A+4B=3..(2)

Let us multiply equation 1 with 2

6A+4B=4...(3)

Subtract equation 3 from 2

4A+4B-6A-4B=3-4

-2A=-1

A=1/2

A=0.5

Hence, the cost of one apple is 0.5, option C is correct.

To reduce the fraction 28/98 to lowest terms, we prime factorize each number, cancel out the common factors, and simplify. The fraction 28/98 simplifies to 1/7.

The correct prime factorization of 28 is 2×2×7 (or 2²×7), and for 98 it's 2×7×7 (or 2×7²). To reduce the fraction 28/98 to lowest terms, we can remove the common factors in the numerator and the denominator.

Since both numerator and denominator have a 2 and a 7, we can replace them with '1'. After simplifying, the remaining factors in the numerator are 1 and the remaining factors in the denominator are 7. Therefore, 28/98 reduced to lowest terms is 1/7.

(x + f) + 2 = j    subtract 2 from both sides

x + f = j - 2       subtract f from both sides

x = j - f - 2

Given that the preference for red and blue pens is equal and that there are 48 workers, Clark should order 24 blue pens for the office.

The student is interested in figuring out how many blue pens to order for 48 workers in an office knowing that the preferences for red and blue pens are equal. This means that for every 6 people who prefer red, the same number of people will prefer blue.

To determine the number of blue pens needed, we can use a simple proportion. Since 6 people prefer red and the same number prefer blue, we have a 1:1 ratio of red to blue preferences.

Therefore, the total number of blue pens needed would be half of the total number of workers:

Answer:

JK = 6

Step-by-step explanation:

Given: We are given a parallelogram JKLM and ML = 6 units. and m∠K = 109°

We need to find length of JK.

Here we use the properties of parallelogram to find the length of Jk.

In a parallelogram, the opposite sides are parallel and equal in measures.

Therefore, ML = JK

Given: ML = 6

So, 6 = JK

Therefore, the length of JK = 6

Answer:

He bought 375 paper clips.

Step-by-step explanation:

Given,

The initial number of packs of paper clips = 7,

Also, the additional number of packs of paper clips = 8,

So, the total number of packs of paper clips = 7 + 8 = 15,

Now, the number of paper clips in each pack = 25,

Hence, the total number of paper clips = number of paper clips in each pack × total packs

= 25 × 15

= 375

The slope of the given equation 12x = 7y - 10y is -4 (constant) thus it will be a linear equation.

A straight line on the coordinate plane is represented by a linear function.

A linear function is a function that varies linearly with respect to the changing variable.

Given the line,

12x = 7y - 10y

12x = -3y

-3y = 12x

Divide both sides by -3

y = -4x

The slope of any function is given as dy/dx or first differential

dydx = -4 so the slope is constant thus the line will be a linear equation.

The graph of the line also has been attached for refernce.

Hence "The slope of the given equation 12x = 7y - 10y is -4 (constant) thus it will be a linear equation".

The equation 12x = 7y - 10y simplifies to 12x = -3y and is a linear equation because it can be rewritten in the form y = mx + b, where m is the slope (-4) and b is the y-intercept (0).

The equation 12x = 7y - 10y simplifies to 12x = -3y, which can then be written in the slope-intercept form as y = -4x. This is a linear equation because it can be expressed in the standard form y = mx + b, where m represents the slope and b is the y-intercept. In this equation, m equals -4 and b equals 0, indicating that the line crosses the y-axis at the origin (0,0).

Similar examples of linear equations include 7y = 6x + 8, 4y = 8, and y + 7 = 3x. These equations all have a constant rate of change, which is characteristic of linear relationships, where one variable is a constant multiple of the other plus a constant (y = a + bx).

Mathematically, we can write it as:

[tex] \frac{15}{100} * x = 75 [/tex]

x = Original Price

The above equation can be read as: "The 15% of the original price is $75."

Now we need to find the value of x:

[tex] x =\frac{75 * 100}{15} = 500 [/tex]

Hence,

The original price is = x = $500
