Point K is on line segment \overline{JL} JL . Given KL=4KL=4 and JL=6,JL=6, determine the length \overline{JK}. JK
Answers
The length of JK is 4
What is a line segment?A line segment can be defined as the part of a straight line bounded by two different or separate end points, and also contains every point on the line between its endpoints.
Note that point K is the midpoint between points J and L
From the information given, we have the points:
JL= x+10KL= 4xJK= 2The expression is given as;
JL = KL + JK
Now, substitute the values
x + 10 = 4x + 2x
collect like terms
10 = 5x
Make 'x' the subject of formula
x = 10/ 5
x = 2
But we have that;
JK = 2x
JK = 2(2)
JK = 4
Thus, the value of JK is 4

Match each expression with A, B, C or D.
A=a^3
B=6a
C=12a
D=3a^2
i)3a x 4
ii)a^2xa
iii) 6 1/2 a^2
Answers
The matching expressions are:
\(i) 3a x 4 = C (12a)\\ii) a^2 x a = A (a^3)\\iii) 6 × 1/2 a^2 = D (3a^2)\)
i) 3a x 4 can be represented as C (12a) since multiplying 3a by 4 gives 12a.
ii) a^2 x a can be represented as A (a^3) since multiplying a^2 by a gives a^3.
iii) \(6 \times 1/2 a^2\) can be represented as D (3a^2) since multiplying 6 by 1/2 and then by a^2 gives 3a^2.
To understand the matching expressions, let's break down each one:
i) 3a x 4:
This expression represents multiplying a variable, 'a', by a constant, 4. The result is 12a, which matches with C (12a).
ii) a^2 x a:
This expression represents multiplying the square of a variable, 'a', by 'a' itself. This results in a^3, which matches with A (a^3).
iii) 6 × 1/2 a^2:
This expression involves multiplying a constant, 6, by a fraction, 1/2, and then multiplying it by the square of 'a', a^2. The final result is 3a^2, which matches with D (3a^2).
Therefore, the matching expressions are:
i) 3a x 4 = C (12a)
ii) a^2 x a = A (a^3)
iii) 6 × 1/2 a^2 = D (3a^2)

(round the answer to the nearest whole number) this is a long divison problem.
Answers
Answer:
uhh judy has $3.024 in her bank acc
She is buying tickets for 11 friends and including herself too that means 12
Two friends decided help to buy the tickets and offered $100 each i.e $200
So I'm guessing that the cost price of one ticket is $100
Now than since 2 people paid their ticket cost than that means only 10 people left
Than for buying tickets for 10 people would cost (10×100=1000)
So I guess buying the tickets cost 1000 or if we add other two people's cost than that makes 1200
find the exact value of x. 45 degree and 10 side
Answers
Answer:
The exact value of the other leg is 10.
Step-by-step explanation:
Finding the exact value of x given a 45 degree angle and a side length of 10 can be done using trigonometry. In a 45-45-90 right triangle, the two legs are congruent and the hypotenuse is equal to the square root of 2 times the length of the legs.
Therefore, if one leg is 10, the hypotenuse is 10 times the square root of 2. To find the length of the other leg, we can use the Pythagorean theorem:
c^2 = a^2 + b^2, where c is the hypotenuse, a and b are the legs of the right triangle.
Substituting known values, we get:
(10√2)^2 = 10^2 + b^2
200 = 100 + b^2
b^2 = 100
b = 10
Therefore, the exact value of the other leg is 10.
B. What is each piece measurement if the angle is cut into 9 equal
lengths? Kerf width is 0.125.
Answers
Each piece Measurement of an angle of 120 degrees cut into nine equal lengths with a kerf width of 0.125 would be 14.4583 degrees.
When a particular angle is cut into nine equal parts, the measure of each piece needs to be calculated.
Therefore, it is essential to first calculate the total angle measure and then divide it by the number of parts into which it is being cut.
What is an Angle?
An angle is a geometrical shape that consists of two rays sharing a common endpoint. The common endpoint is known as the vertex, and the two rays are known as the arms of the angle. An angle can be measured in degrees, radians, or gradians. Degrees are the most commonly used unit of measuring angles.How to Calculate Each Piece Measurement of an Angle if Cut into 9 Equal Lengths
To determine each piece measurement of an angle if cut into nine equal lengths, we will need to carry out the following steps:
Step 1: Calculate the total angle measure Suppose the angle being cut into nine equal lengths is an obtuse angle measuring 120 degrees. In that case, the total angle measure will be 120 degrees.
Step 2: Divide the total angle measure by the number of parts into which it is being cut.120 degrees ÷ 9 = 13.3333 degrees
Step 3: Add the kerf width to the piece measurements.0.125 x 9 = 1.125 degrees13.3333 + 1.125 = 14.4583 degrees
Therefore, each piece measurement of an angle of 120 degrees cut into nine equal lengths with a kerf width of 0.125 would be 14.4583 degrees.

Bill caught three catfish and one trout. Two of the catfish were 19 in long. The other was 16.9 in long and the trout was 17.2 in long. What was the average length of the catfish? A. 16.2 in B. 17.6 in C. 18.3 in D. Not given
Answers
Answer:
C. 18.3 in
Explanation:
Forget the trouts, since we are only asked about the length of the catfish.
Now bill caught three catsfish. Let us see their lengths.
Length of catfish 1 = 19 in
Length of catfish 2 = 19 in
Length of catfish 3 = 16.9 in
Therefore, the average length of the three catfish is
\(\frac{19+19+16.9}{3}=18.3\)Hence, the average length of the catfish is 18.3 in. Therefore, choice C is the correct answer!

Using long division divide y cubed + 0y squared minus 1 by y +4
Answers
Given the expression:
\(\frac{y^3+0y^2-1}{y+4}\)Step 1:
Divide the leading term of the dividend by the leading term of the divisor. Multiply the result by the divisor and subtract the final result from the dividend as follows:
\(\begin{gathered} \frac{y^3}{y}=y^2 \\ \\ \\ y^2(y+4)=y^3+4y^2 \\ \\ \\ (y^3-1)-(y^3+4y^2)=-4y^2-1 \end{gathered}\)Step 2: Divide the leading term of the obtained remainder by the leading term of the divisor, multiply it by the divisor, and subtract the remainder from the obtained result:
\(\begin{gathered} \frac{-4y^2}{y}=-4y \\ \\ \\ -4y(y+4)=-4y^2-16y \\ \\ \\ (-4y^2-1)-(-4y^2-16y)=16y-1 \end{gathered}\)Step 3: Divide the leading term of the obtained remainder by the leading term of the divisor, multiply it by the divisor, and subtract the remainder from the obtained result:
\(\begin{gathered} \frac{16y}{y}=16 \\ \\ \\ 16(y+4)=16y+64 \\ \\ \\ (16y-1)-(16y+64)=-65 \end{gathered}\)Since the degree of the remainder is less than the degree of the divisor, we would stop.
Therefore, the answer is:

Answer: X= 108125 and Y = 373125.
Step-by-step explanation:
Given system :
\(X= 33500+0.2Y (i)\\\\ Y=26500+0.1X (ii)\)
Consider (ii)
\(Y=26500+0.1X\\\\\Rightarrow\ Y-0.1X=26500\)
Multiply 10 on both sides , we get
\(10Y-X=265000 (iii)\)
Add (i) and (iii)
\(10Y= 33500+26500+0.2Y\\\\\Rightarrow\ 10Y-0.2Y= 298500\\\\\Rightarrow\ 0.8Y= 298500\\\\\Rightarrrow\ Y=\dfrac{298500}{0.8}\\\\\Rightarrrow\ Y=373125\)
Put this in (i)
\(X= 33500+0.2(373125) =108125\)
Hence, X= 108125 and Y = 373125.
For the given confidence level and values of x and n, find the following.
x=45, n=96, confidence level 95%
Answers
The confidence interval based on the given values (x = 45, n = 96, Confidence level = 95%.
The confidence level (95%), sample size (n = 96), and sample mean (x = 45), we can calculate the margin of error and the confidence interval. Here's how:
1. Margin of Error:
The margin of error represents the maximum expected difference between the true population parameter and the sample estimate. It depends on the confidence level and the standard deviation (which we don't have in this case).
Since the standard deviation is unknown, we can use the t-distribution to estimate it. With a sample size of n = 96, the degrees of freedom are (n - 1) = 95. Considering a 95% confidence level, the critical value for a two-tailed test is approximately 1.984 (referencing a t-distribution table or calculator).
The margin of error (E) can be calculated using the following formula:
E = critical value * (standard deviation / sqrt(n))
However, since we don't have the standard deviation, we can't compute the margin of error in this case.
2. Confidence Interval:
The confidence interval represents a range of values within which the true population parameter is likely to fall.
The confidence interval can be calculated using the formula:
CI = x ± (critical value * standard deviation / sqrt(n))
The confidence interval based on the given values (x = 45, n = 96, confidence level = 95%.

Answer: Point C means that $80 on tickets for 5 games. The unit rate can be represented by the point (5, 80) on the graph.
Step-by-step explanation:
Answer: Point C means that Danny spent $80 on tickets for 5 games. The unit rate can be represented by the point (1, 16) on the graph.
Step-by-step explanation:
Point C is aligned with the 5 mark on the x-axis. The x-axis represents the number of games attended by Danny, so we know he attended 5 games. The point is also aligned with the 80 mark on the x-axis. The x-axis represents the amount Danny spent on the 5 tickets.
In order to find the unit rate, we need to find how much Danny spent per ticket. If Danny spent $80 on 5 tickets, we can divide 80 by 5 to find out the cost per ticket, which is the unit rate.
80 ÷ 5 = 16
Your unit rate is 16 dollars per ticket, so your coordinate is (1, 16).

Answer:
\(\boxed {\tt -4 \textdegree \ per \ hour }\)
Step-by-step explanation:
This question asks us to find the average rate of change in temperature per hour.
Therefore, we must divide the temperature change by the hours.
\(rate \ of \ change =\frac{temperature \ change}{hours}\)
The temperature dropped 24 degrees in 6 hours. Since it dropped, the change was negative.
\(temperature \ change = -24 \textdegree \\hours = 6 \ hours\)
Substitute the values into the formula.
\(rate \ of \ change =\frac{-24 \textdegree}{6 \ hours}\)
Divide.
\(rate \ of \ change = - 4 \textdegree / hour\)
The average change in temperature was -4° per hour. The temperature dropped 4 degrees each hour.
