Charmaine must choose a number between 61 and 107 that is a multiple of 3, 6 and 8. Write all the numbers that she could choose. If there is more than one number, separate them with commas.
Answer: 72, and 96
Step-by-step explanation:
Multiples of 3 between 61 and 107 are= 63,66,69,72,75,78,81,84,87,90,93,96,99,102,105
Multiples of 6 between 61 and 107 are:
= 66,72,78,84,90,96,102
Multiples of 8 between 61 and 107 are:
= 64,72,80,88,96,104
The common multiple to 3, 6 and 8 from 61 to 107:

I thought it was HL, but I was wrong. So I’m really confused. Help?
Answer:
Its asa
Step-by-step explanation:
Answer:
The answer to your question is the ASA(Angle-Side-Angle) postulate
Step-by-step explanation:
The reason this is not HL(hypotenuse leg) is because only one side, and two angles are marked as congruent, you need a congruent(equal measure) leg, hypotenuse, and right angle. In other words, you need a right triangle with a congruent hypotenuse, and leg ; tick marks, to indicate the sides have equal length(these are the slashes that go through the line or outline). An outline of the angle or tick on the outline corresponds to congruent angles.
Because you have two angles and a side, in the order of an angle then a side and then an angle, it is ASA.

Answer: A coordinate plane with straight line. The line starts at (negative 4, negative 5) and passes through points at (0, 0) and (4, 5). That is the answer.
A coordinate plane with straight line. The line starts at (negative 5, negative 2) and passes through points at (negative 1, 0) and (4, 5).
What is slope?The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as,
The slope of line is the measure of steepness or the direction of line the coordinate plane.
m = Δy/Δx
where,m is the slope
tan θ = Δy/Δx
We also refer this tan θ to be the slope of the line.
Slope of a LineThe slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane. Calculating the slope of a line is similar to finding the slope between two different points. In general, to find the slope of a line, we need to have the values of any two different coordinates on the line.
Given:
slope= 4/5
The graph which show the slope 4/5 is:
A coordinate plane with straight line. The line starts at (negative 5, negative 2) and passes through points at (negative 1, 0) and (4, 5).

Use the vertical line test to determine if the graph is a function or not a function.
Answer:
Use the vertical line test to determine if the graph is a function or not a function.
On a coordinate plane, a graph decreases to a minimum point, and then increases.
✔ function
On a coordinate plane, a graph increases to a maximum, decreases to a minimum, increases to the maximum, and decreases again to the minimum.
✔ function
On a coordinate plane, a graph decreases to the right, then decreases to the left, then decreases to the right.
✔ not a function
Step-by-step explanation:
As per the concept of the vertical line test, the third graph is not a function.
But the First and Second graphs represent a function.
The vertical line test is a method used to determine if a graph represents a function. It involves visually inspecting the graph and checking if any vertical line intersects the graph at more than one point.
Let's apply the vertical line test to the given graphs:
First graph:
For the first graph, if we draw any vertical line, it will intersect the graph at most once. Hence, the graph passes the vertical line test, indicating that it represents a function.
Second graph:
For the first graph, if we draw any vertical line, it will intersect the graph at most once. Hence, the graph passes the vertical line test, indicating that it represents a function.
Third graph:
The vertical line test is given in the image below.
In conclusion:
The third graph is not a function.

A company that manufactures widgets has fixed costs of $8,906.00 each month and a cost of $2.64 for each widget it produces. Which of the following equations could be used to determine the total production costs for the company if it produced x widgets last month?
(Let x represent the number of widgets the factory produced last month and y represent the total production costs for the factory.)
A.
y = $890.60 + $2.64x
B.
y = $8,906.00 + $2.64x
C.
y = $8,906.00x - $2.64x
D.
y = $2.64 + $8,906.00x
Answer:
The equation could be used to determine the total production costs for the company if it produced x widgets last month is
y = $8,906.00 + $2.64x ⇒ B
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope ⇒ rate of changeb is the y-intercept ⇒ initial amount∵ A company has fixed costs of $8,906.00 each month
→ That means it is a fixed value every month
∴ b = 8,906.00
∵ The cost of each widget it produces is $2.64 for
→ That means the value is changing according to the number of widgets
∴ m = 2.64
∵ y represents the total costs of production last month
∵ x represents the number of widgets the factory produced last month
→ Substitute the values of m and b in the form of the equation above
∴ y = 2.64x + 8,906.00
The equation could be used to determine the total production costs for the company if it produced x widgets last month is
y = $8,906.00 + $2.64x

The total cost for 10 pairs of headphones, including shipping was $125. The shipping charge was $15. What was the cost of each pair of headphones? Write and an equation and find the solution.
Answer:
y=15+12.5xStep-by-step explanation:
given data
chipping charge= $15
cost of 10 pair= $125
le the cost of 1 pair be x
given that 10 pairs cost $125
then 1 would cost x
cross multiply we have
10x=$125
x= 125/10
x=$12.5
therefore the equation for the solution is
let y be the total cost
y=15+12.5x

Rectangle A measures 12 cm by 3 cm. Rectangle B is a scaled copy of Rectangle A. Select all of the measurement pairs that could be the dimensions of Rectangle B.
A. 6 cm by 1.5 cm
B.10 cm by 2 cm
C. 13 cm by 4 cm
D.18 cm by 4.5 cm
E.80 cm by 20 cm
Answer:
The correct answers are:
A. 6 cm by 1.5 cm
D. 18 cm by 4.5 cm
E. 80 cm by 20 cm
Step-by-step explanation:
A scaled copy of the original rectangle will have different dimensions, but with the same ratio of the dimensions to the original unscaled rectangle. Therefore, to determine the dimensions that are scaled copies of the original rectangle, we have to determine the ratio of the dimension of the original rectangle and also find the ratios of the other rectangles, the ratios that match are scaled copies. This is done as follows:
Rectangle A:
12cm by 3 cm = 12/3 = 4
other rectangles:
A. 6cm by 1.5cm = 6/1.5 = 4
B. 10cm by 2cm = 10/2 = 5
C. 13cm by 4cm = 13/4 = 3.25
D. 18cm by 4.5cm = 18/4.5 = 4
E. 80cm by 20 cm = 80/20 = 4
The rectangles that match the original rectangle are A, D, and E, hence they are scaled copies of the rectangle A

Emir is creating sewing kits for local high school students who are heading off to college. He has 16 needles and 12 spools of thread, which he wants to divide evenly, with no materials left over. What is the greatest number of sewing kits Emir can make?
Answer: 4
Step-by-step explanation:
Given that :
Number of needles = 16
Numbe of spools of thread = 12
The greatest Number of sewing kits that can be made is found by obtaining the Greatest Common factor of both number of threads and number of spool of thread;
Factor of :
16 : 1, 2, 4, 8, 16
12 : 1, 2, 3, 4, 6, 12
Hence, the greatest common factor = 4
