5) Draw a circle with the fixed end of the compass on point H.
The correct arrangement of the steps will be D ⇒ B ⇒ E ⇒ A ⇒ C.
What is a triangle?A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.
The triangle is a highly common shape that we deal with on a daily basis. For instance, the right-angle triangle is frequently used to estimate the height of towers.
In a triangle, the sum of all three angles is 180°
The correct sequence of the given problem should be ;
(D) ⇒ Construct the angle bisectors of angle JKL and angle LJK.
(B) ⇒ Label the point of intersection of the bisectors point H
(C) ⇒ Construct a segment HM that intersects side JK perpendicularly at point M.
(D) ⇒ Set the compass length to HM.

Graph A represents the exponential equation y=4(6) and graph B represents y=6(4). which statements are true about graph a and graph b
Answer:
Step-by-step explanation:The following statements are true about exponential functions:
-The domain is all real numbers.
- The input to an exponential function is the exponent.
- The base represents the multiplicative rate of change.
The reason why the other two options are wrong are explained below:
The range of exponential functions is not always includes negative numbers; on the contrary, the range is the set of all positive real numbers.
The graph of an exponential function does not have a horizontal asymptote at x = 0; contrarily, the equation of the horizontal asymptote of the graph of is y = 0, which is the x-axis.

Which is the better buy?
2-pint bottle of bleach for $1.86
2-gallon bottle of bleach for $10.56
Answer:
gallon bottle
Step-by-step explanation:
There are 8 pints in a gallon, so 8 of the 2-pint bottles would be equivalent to 2 gallons. The cost of those would be ...
8 × $1.86 = $14.88
This is greater than the $10.56 cost of a 2-gallon bottle, so the 2-gallon bottle offers a better buy for an equivalent quantity.
__
Additional comment
You could compare unit rates in terms of any of cost per ounce, cost per pint, cost per quart, cost per gallon. All that is needed is the cost for an equivalent quantity, or the quantity for an equivalent cost.
Or, one can look at cost and quantity ratios. The cost ratio is 10.56/1.86 ≈ 5.68; the quantity ratio is (16 pints)/(2 pints) = 8. The gallon size gives 8 > 5.7 times the product for 5.7 times the cost, so it is the better buy.
fond the 7th term of the geometric sequence whose common ratio is 1/3 and whose first term is 4
Answer:
[tex]a_7=\dfrac{4}{729}[/tex]
Step-by-step explanation:
General form of geometric progression: [tex]a_n=ar^{n-1}[/tex]
(where [tex]a[/tex] is the initial term and [tex]r[/tex] is the common ratio)
Given:
[tex]a=4[/tex][tex]r=\dfrac13[/tex][tex]\implies a_n=4\left(\dfrac13\right)^{n-1}[/tex]
Therefore, when n = 7:
[tex]\implies a_7=4\left(\dfrac13\right)^{7-1}[/tex]
[tex]\implies a_7=4\left(\dfrac13\right)^{6}[/tex]
[tex]\implies a_7=4\left(\dfrac{1^6}{3^6}\right)[/tex]

For which value(s) of x are the triangles congruent?
Step-by-step explanation:
The solutions are 2 and 5
Because it's asking what would make the triangles congruent, you would set up the equation like this because the angles (angle 3 and angle 4) need to be equal:
x^2 = 7x - 10
Next, you add 10 to both sides. This is so that you can move it to the other side, addition is the inverse of subtraction.
x^2 + 10 = 7x
Now subtract 7x from both sides. Subtraction is the inverse of addition. You do this to get it on the other side so you can factor it. You can move the 10 and 7x to the other side in any order or at the same time, I just did it like this.
x^2 - 7x + 10 = 0
Now, factor. I don't really know how to explain factoring, you just get a feel for it with a lot of practice.
(x - 2)(x - 5) = 0
You can use FOIL to check this if you want to. x(x) is x^2, -2(-5) is 10), -2x - -5x is -7x. Now, find what you need to do to make what's in each of the groups of parentheses equal to 0.
x - 2 = 0
x = 2
One of the solutions is 2, because you add 2 to x to get 0.
x - 5 = 0
x = 5
The other solution is 5, because you add 5 to x to get 0. Lastly, check your solutions by plugging them in to the original equation.
2^2 = 7(2) - 10
4 = 14 - 10
So 2 is definitely a solution.
5^2 = 7(5) - 10
25 = 35 - 10
5 is also a solution.
Hope that helps :]
Which equation represents a line that passes through (–9, –3) and has a slope of –6?
y – 9 = –6(x – 3)
y + 9 = –6(x + 3)
y – 3 = –6(x – 9)
y + 3 = –6(x + 9)
Answer:
y+3= -6(x+9)
Step-by-step explanation:
Slope is represented as M
Name the numbers in bracket as y1 and x1
You have to use the formula which is:y-y1=m(x-x1)
Then you substitute the numbers into the formula
y--3=-6(x--9)
when two negatives meet the turn to positive
thats how we can conclude that the answer is y+3=-6(x+9)

Shay's net earnings per month are $4000. Shay's total monthly expenses are $3000. The biggest expense is rent at $1500. If Shay takes on a roommate who pays $500 per month, by what amount has Shay reduced total monthly expenses?
Group of answer choices
1/8 or 13%
1/6 or 17%
1/3 or 33%
1/2 or 50%
Answer:1/6 or 17%
Step-by-step explanation:
Explanation:
Ignore the net earnings of $4000 as it's extra unneeded info. The same goes for the $1500 rent.
Shay has monthly expenses of $3000. If the roommate chips in $500, then Shay saves 500/3000 = 5/30 = 1/6 of her money toward expenses.
Using a calculator, 1/6 = 0.17 = 17% approximately

The first number indicates the row number and the second number indicates the column number. Therefore B13،That is, the first row and the third column. -1
A matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns. -1 is the value of B13.
What is Matrix?A matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns.
The given matrix is [tex]B=\left[\begin{array}{ccc}2&5&-1\\0&-3&8\end{array}\right][/tex]
We need to find the value of B13.
In B13 the number one represents the row 1 and 3 represents the columns 3.
So the element in B13 position is third element of first row or first element of the third column.
-1 is the third element of first row and first element of the third column
Hence -1 is the B13 of the matrix.

We also know that the ratio of students who A's to students who got B's is 3 : 4
The 8 students that got B's is represented by 4 in the ratio.
8 / 4 = 2
Since we can multiply 4 by 2 to get 8, we can do the same to 3 to find out how many students got A's

Given :
The Perimeter of the rectangle is 98 inchesThe ratio of the length to the width is 4:3.To Find :
The Length and width of the rectangle .⠀
Solution :
We know that,
[tex]\qquad{ \bold{ \pmb{2(Length + Breadth ) = Perimeter_{(rectangle)}}}}[/tex]
Let's assume the length of the rectangle as 4x inches. and the width is 3x inches.
⠀
Now, Substituting the given values in the formula :
[tex]\qquad \dashrightarrow{ \sf{2(4x + 3x )= 98}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{2(7x)= 98}}[/tex]

What is the perimeter of the triangle shown to the nearest tenths
Answer:
22 (I think)
Step-by-step explanation:
The picture is a lil blurry so I'm not sure if I counted the squares right. But basically, you count the squares from one dot to the next. For example, the one on the top that goes in a horizontal line is 6 squares. As for the other two lines, you count from the dot you're starting at and count VERTICALLY until you reach the same line as the point of the triangle. Like with the left side, it starts at point -5, 4 and you'll count how many squares it takes until you reach the same y-axis line as the tip of the triangle. So you should get to -5, -4 for the left side which counts to 8 squares. Same for the other side, also being 8 squares. Then just add it up. 8+8+6=22.
A manufacturing company has two assembly lines, one with old equipment and
one with new. The old assembly line generates products at a rate of 48 per hour,
the new one at 60 per hour. If both assembly lines are operating at the same
time, how long will it take them to create a total of 180 products?
Answer:
the first one would take 3 hours and 45 mins to make 180 by itself
the second one would take 3 hours to make 180 by its self
if this ant the answer let me know
Using unitary method, the manufacturing company will take 1 hour 40 minutes to create a total of 180 products.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Number of products generated by old assembly line in 60 minutes = 48
Number of products generated by old assembly line in 1 minute = 48/60 = 0.8
Number of products generated by new assembly line in 60 minutes = 60
Number of products generated by new assembly line in 1 minutes = 60/60 = 1
Total production in 1 minute = 1 + 0.8 = 1.8
Time taken to produce 180 products = 180/1.8 = 100 minutes = 1 hour 40 minutes
