Use parallelogram JKLM to find the length of JK.
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

The sum of two consecutive integers is at least 46. What is the least possible pair of integers?
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.

Algebraic terms are separated by plus (+) and minus (-) signs, which denote addition or subtraction between terms in an expression.
Explanation:
Algebraic terms are separated by plus (+) and minus (-) signs.
These signs denote addition or subtraction between terms in an algebraic expression.
While the multiplication sign (x) and division sign (÷) indicate operations between terms, they do not separate independent terms within an expression.
For instance, in the expression 2x + 3y - 5z, the plus and minus signs separate the terms 2x, 3y, and 5z.

circle of the radius of 3 an arc of a circle has a central angle of 340 degrees what is the length of the arc
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.
Clark wants to figure out how many pens to order for the office there 48 workers and he needs to order one pen for each worker he knows that for every six people who prefer red door 6 prefer blue how many blue pens should he order
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.
Explanation: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:
Total workers = 48Number of blue pens = Total workers / 2 = 48 / 2Number of blue pens = 24Factor of 3x^2 - 6x 3

Find the equation of the tangent line to the curve y = 2sinx at the point (pi/6,1). The equation of this tangent line can be written in the form y = mx+b. Compute m and b
The equation of the tangent line to the curve y = 2sinx at the point (pi/6,1) is y = sqrt(3)x + (1 - sqrt(3)(pi/6)).
Explanation:To find the equation of the tangent line to the curve y = 2sinx at the point (pi/6, 1), we need to find the slope of the curve at that point. The slope of a curve at a point is equal to the derivative of the function at that point.
Taking the derivative of y = 2sinx, we have dy/dx = 2cosx. Evaluating this derivative at x = pi/6, we get dy/dx = 2cos(pi/6) = sqrt(3). Therefore, the slope of the tangent line is sqrt(3).
Now we have the slope and a point on the line, (pi/6, 1). We can use the point-slope form of a line, y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope.
Plugging in the values, we have y - 1 = sqrt(3)(x - pi/6).
Simplifying this equation, we get y = sqrt(3)x - sqrt(3)(pi/6) + 1. Finally, we can rewrite the equation in the form y = mx + b by simplifying the y-intercept, giving us y = sqrt(3)x + (1 - sqrt(3)(pi/6)).

f(x)= ______x+________"
Answer:
[tex]f(x)=\dfrac{1}{4}x+25[/tex]
Step-by-step explanation:
Clearly from the graph we could see that it passes through two points (0,25) and (20,30) and also as the graph is linear so with the help of these two points we can find the relation between f(x) and x.
We know that the equation of a line passing through two points (a,b) and (c,d) is given by:
[tex]y-b=\dfrac{d-b}{c-a}\times (x-a)[/tex]
Here we have:
y=f(x) , (a,b)=(0,25) and (c,d)=(20,30).
Hence the equation of this graph is given as:
[tex]f(x)-25=\dfrac{30-25}{20-0}\times (x-0)\\\\f(x)-25=\dfrac{5}{20}\times x\\\\f(x)-25=\dfrac{1}{4}\times x\\\\f(x)=\dfrac{1}{4}x+25[/tex]
Hence,
[tex]f(x)=\dfrac{1}{4}x+25[/tex]

Find the correct prime factorization of 28/98, and then reduce the fraction to lowest terms. ...?
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.
Kamal bought 7 packs of paper clips for a project. then he bought 8 more packs. there are 25 paper clips in each pack. how many paper clips did he buy?
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

Celeste is making fruit baskets for her service club to take to a local hospital. the directions say to fill the boxes using 5 apples for every 6 oranges. celeste is filling her baskets with 2 apples every 3 oranges.
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.
Explanation: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.
