Answer:
The probability that both spinners will land on 2 is A) 1/12.
Step-by-step explanation:
To get this answer you must:
-First, take the total number of outcomes and set that as you denominator, which would be 3.
-Since, your looking for the probability of two, and there is only one two you would put one as your numerator. By now you should have a fraction of: 1/3.
-Next, do the same exact thing for the next graph. Take the total number of outcomes for the graph which is 4, and set that as your denominator.
-Then, set one as your numerator since there is only one two in the other graph. You should now have a second fraction of: 1/4.
-Lastly, multiply both of the fractions. Multiply both of the numerator together and you should get one. Then, multiply both of the numbers which would result in you getting a number of 12.
1/3(1/4) = 1/12.

Step-by-step explanation:
Triangle ABC has vertices at A(2,3),B(-4,-3) and C(2,-3) find the coordinates of each point of concurrency.
Circumcenter ________
Orthocenter ________
Can someone please help me with this? and if you can explain how to do it?
Answer:
Circumcenter =(-1,0)
Orthocenter =(2,-3)
Step-by-step explanation:
Given : Points A = (2,3), B = (-4,-3), C = (2,-3)
Formula used :
→Mid point of two points- [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
→Slope of two points - [tex]\frac{y_2-y_1}{x_2-x_1})[/tex]
→Perpendicular of a line = [tex]\frac{-1}{slope of line})[/tex]
Circumcenter- The point where the perpendicular bisectors of a triangle meets.
Orthocenter-The intersecting point for all the altitudes of the triangle.
To find out the circumcenter we have to solve any two bisector equations.
We solve for line AB and AC
So, mid point of AB =[tex](\frac{2-4}{2},\frac{3-3}{2})=(-1,0)[/tex]
Slope of AB =[tex]\frac{-3-3}{-4-2}=1[/tex]
Slope of the bisector is the negative reciprocal of the given slope.
So, the slope of the perpendicular bisector = -1
Equation of AB with slope -1 and the coordinates (-1,0) is,
(y – 0) = -1(x – (-1))
y+x=-1………………(1)
Similarly, for AC
Mid point of AC = [tex](\frac{2+2}{2},\frac{3-3}{2})=(2,0)[/tex]
Slope of AC = [tex]\frac{-3-3}{2-2}=\frac{-6}{0}[/tex]
Slope of the bisector is the negative reciprocal of the given slope.
So, the slope of the perpendicular bisector = 0
Equation of AC with slope 0 and the coordinates (2,0) is,
(y – 0) = 0(x – 2)
y=0 ………………(2)
By solving equation (1) and (2),
put y=0 in equation (1)
y+x=-1
0+x=-1
⇒x=-1
So the circumcenter(P)= (-1,0)
To find the orthocenter we solve the intersections of altitudes.
We solve for line AB and BC
So, mid point of AB =[tex](\frac{2-4}{2},\frac{3-3}{2})=(-1,0)[/tex]
Slope of AB =[tex]\frac{-3-3}{-4-2}=1[/tex]
Slope of the bisector is the negative reciprocal of the given slope.
So, the slope of CF = -1
Equation of AB with slope -1 and the coordinates (-1,0) gives equation CF
(y – 0) = -1(x – (-1))
y+x=-1………………(3)
Similarly, mid point of BC =[tex](\frac{-4+2}{2},\frac{-3-3}{2})=(-1,-3)[/tex]
Slope of AB =[tex]\frac{-3+3}{-4-2}=0[/tex]
Slope of the bisector is the negative reciprocal of the given slope.
So, the slope of AD = 0
Equation of AB with slope 0 and the coordinates (-1,-3) gives equation AD
(y-(-3)) = 0(x – (-1))
y+3=0
y=-3………………(4)
Solve equation (3) and (4),
Put y=-3 in equation (3)
y+x=-1
-3+x=-1
x=2
Therefore, orthocenter(O)= (2,-3)
To find the coordinates of the Circumcenter of Triangle ABC, we find the equations of the perpendicular bisectors of two sides and solve them simultaneously. To find the coordinates of the Orthocenter, we find the equations of the altitudes and solve them simultaneously.
Explanation:The Circumcenter of a triangle is the point of concurrency of the perpendicular bisectors of the triangle's sides. The Orthocenter of a triangle is the point of concurrency of the triangle's altitudes. To find the coordinates of the Circumcenter, we can find the equations of the perpendicular bisectors of two sides of the triangle and solve them simultaneously. To find the coordinates of the Orthocenter, we can find the equations of the altitudes and solve them simultaneously.

I don’t want the answer but how to do solve this problem and how to solve scale factors...please help!!
Step-by-step explanation:
Scale Factor (SF)
The scale factor is the number you multiply the real by to get the model, it can also be used the other way, for instance if a map's SF was 1in=1ft (or times 12) every 2 inches on the map would be 24 inches (or 2 ft) in real life.
If the SF is lower than 1 (a decimal like .7 for instance) then the result will be smaller (for Real to Model)
for the first one, 80 times the SF will equal 25
80 * X = 25
^Here is it in equation form, X being the scale factor
isolate X (or find what x equals by getting it by itself)
divide each side by 80
X = 25/80
simplify or divide
X = 5/16 or x = 0.3125 (Both of these ca.
Lyla grew 16 flowers with 2 seed packets. How many seed packets does Lyla need to have a total of 40 flowers in her garden? Assume the relationship is directly proportional. ____ seed packets
Lyla needs 5 seed packets to grow a total of 40 flowers, assuming the relationship between flowers and seed packets is directly proportional.
Explanation:Lyla grew 16 flowers with 2 seed packets. To find out how many seed packets Lyla needs to grow a total of 40 flowers, assuming the relationship is directly proportional, we set up a proportion. We have the ratio of flowers to seed packets, which is 16 flowers for 2 seed packets. We need to find how many seed packets would be needed for 40 flowers.
First, write the proportion:
\(\frac{16 \text{ flowers}}{2 \text{ seed packets}} = \frac{40 \text{ flowers}}{x \text{ seed packets}}\)
Solve for \(x\):
\(\frac{16}{2} = \frac{40}{x}\)
\(8 = \frac{40}{x}\)
Multiply both sides by \(x\) and divide both sides by 8 to find the value of \(x\):
\(x \cdot 8 = 40\)
\(x = \frac{40}{8}\)
\(x = 5\)
Therefore, Lyla needs 5 seed packets to grow 40 flowers.

Answer:
A and D. SSS theorem
B. ASA or AAS theorems
C. SAS theorem
E. AAS theorem
Step-by-step explanation:
SSS theorem states that if three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
SAS theorem states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
AAS theorem states that if two angles and the non-included side one triangle are congruent to two angles and the non-included side of another triangle, then these two triangles are congruent.
ASA theorem states that if two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
Thus:
A. If each pair of corresponding sides is congruent, then two triangles are congruent by SSS theorem.
B. If two pairs of corresponding angles are congruent and a pair of corresponding sides are congruent, then two triangles are congruent by ASA or AAS theorems.
C. If two pairs of corresponding sides and the angles included between them are congruent, then two triangles are congruent by SAS theorem.

What is the relationship between 0.8 ÷ 10^2 and 0.8×10^2
[tex]0.8\times10^2\ \text{is 10,000 times greater than}\ 0.8\div10^2\\\\\dfrac{0.8\times10^2}{0.8\div10^2}=\dfrac{10^2}{1\div10^2}=\dfrac{10^2}{\frac{1}{10^2}}=10^2\times10^2=10^4=10,000[/tex]
Dividing 0.8 by 10² moves the decimal two places to the left, resulting in 0.008. Multiplying 0.8 by 10² moves the decimal two places to the right, resulting in 80. Thus, the two operations produce different magnitudes of the original number.
Understanding the Relationship Between 0.8 ÷ 10² and 0.8 × 10²:
In mathematics, it's essential to understand how operations involving powers of ten affect numbers. Let’s break down the operations:
0.8 ÷ 10²: When you divide a number by 10 raised to the power of 2 (which is 100), you move the decimal point two places to the left. So, 0.8 ÷ 100 = 0.008.
0.8 × 10²: When you multiply a number by 10 raised to the power of 2, you move the decimal point two places to the right. So, 0.8 × 100 = 80.
We can conclude that 0.8 ÷ 10² results in moving the decimal to the left, making the number smaller (0.008), while 0.8 × 10² results in moving the decimal to the right, making the number larger (80).

which equation describes the line which passes through the points (0. 17, 0) and (0, 0.51)
The equation of the line passing through the points (0, 17) and (0, 0.51) is x = 0.
Explanation:The equation of the line that passes through the points (0, 17) and (0, 0.51) can be found using the slope-intercept form of a linear equation, which is y = mx + b. To find the slope (m), we use the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.
Substituting the given points, we get m = (0.51 - 17) / (0 - 0) = -16.49 / 0, which is undefined.Since the slope is undefined, we cannot write the equation in the slope-intercept form.However, we can write the equation as x = 0, since the line passes through the x-coordinate of both points.

The height y (in feet) of a toss in bocce ball can be modeled by y=-x^2+4x, where x is the horizontal distance (in feet)
Interpret the x-intercepts of the graph of the equation.
How far does the bocce ball land on the ground?
The x-intercepts of the equation represent the points where the height of the toss is equal to 0. The bocce ball lands on the ground at a horizontal distance of 0 feet and 4 feet.
Explanation:The x-intercepts of the graph of the equation represent the points where the height of the toss is equal to 0.
In other words, these points represent the horizontal distance where the bocce ball lands on the ground.
o find the x-intercepts, we set y=0 and solve the equation:
0=-x^2+4x
x(x-4)=0
Therefore, the x-intercepts are x=0 and x=4.
This means that the bocce ball lands on the ground at a horizontal distance of 0 feet and 4 feet.

Juan rolls a 6-sided number cube 4 times. The result is 2. Which best describes the events?
Answer:1/6
Step-by-step explanation: because there are 6 side to a cube and you can only have a outcome of 1 so therefore, the answer is 1/6
Final answer:
Juan's experience of rolling the number 2 on a six-sided die 4 times deals with the concept of independent events in probability. The probability of getting a 2 on any single roll is 1/6 and to roll a 2 four times consecutively, you multiply the probabilities, resulting in a much smaller overall probability.
Explanation:
The question involves understanding the probability of rolling a certain number on a six-sided die, which is a concept in mathematics. When Juan rolls the six-sided number cube 4 times and gets the result of 2 each time, we are analyzing a sequence of independent events in probability. Since each roll of the die is independent, the outcome of one roll does not affect the outcome of the next roll and the probability of rolling a 2 on each individual roll remains constant at 1/6.
Event X, described as rolling an even number, has a probability of 3/6 or 1/2, since the even numbers on a die are 2, 4, and 6. However, the probability of rolling multiple 2's in sequence would be the product of probabilities for each roll. That is, the probability of rolling a 2 four times in a row would be (1/6) * (1/6) * (1/6) * (1/6), which is a much smaller probability. This reflects the notion that rolling the same number consecutively multiple times is less likely than rolling it once.

The 10% of people who received the email are in the original 15 people.
What is percent?A number or ratio that can be expressed as a fraction of 100 is called a percentage. Divide the number by its whole number and multiply it by 100 if we have to figure out the percentage of that number. Consequently, the percentage represents one part per hundred. The word "per 100" means "per percent." The number "%" is used to symbolize it.
Given email received by people = 15
sent to 3 different people
the number of people have email = 15 x 3 = 45
then 45 people send it to 2 new
number of people email have = 45 x 2 = 90
total number of person who have email = 15 + 45 + 90 = 150
To the percent of 15 people in a group of 150 people by diving 15 by 150
15/150(100) = 10%
Hence people who received the email are in original 15 is 10%.
