Select the procedure that can be used to show the converse of the Pythagorean theorem using side lengths chosen from 5 cm, 9 cm, 12 cm, and 15 cm
Answer:
Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.
Step-by-step explanation:Pythagorean Theorem: According to this theorem the result obtained by squaring the value of the hypotenuse of a right angled triangle is equal to the sum of the squares of the values other two sides of the triangle.
Hypotenuse = h
Altitude = l
Base = b
l²+b²=h²
Here 6²=36
9²=81
12²=144
15²=225
From the above it is clear that
81+144=225
⇒9²+12²=15²
Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.
Hope this helps!

Answer:
Equation: y = 2x
Graph: see attachment
Step-by-step explanation:
Pieces of paper = x
Number of Valentines = y
The equation is a proportional equation and can be represented as y = kx
k is the constant of proportionality
k = y/x
Using (2, 4),
k = 4/2 = 2
To find the equation, substitute k = 2 into y = kx
Thus:
y = 2x

Describe the congruence transformation that maps quadrilateral ABCD to quadrilateral A'B'C'D'.
Question 27 options:
270° counterclockwise rotation
Reflection across the y-axis
90° clockwise rotation
90° counterclockwise rotation
Answer:
90 degree counterclockwise rotation
Step-by-step explanation:
After a 90° counterclockwise rotation, we get the required quadrilateral A'B'C'D'.
Hence the fourth option is correct.
The rotation of axes refers to a transformation in which the coordinate axes in a coordinate system are rotated to form new axes.
When we rotate the quadrilateral ABCD about 90 degrees counterclockwise,
The new position of vertices be,
A ⇒ B'
B ⇒ C'
C ⇒ D'
D ⇒ A'
Hence,
After this rotation, we get the required quadrilateral A'B'C'D' as shown in the figure.
Hence,
After 90° counterclockwise rotation we get such a triangle.

g A survey of athletes at a high school is conducted, and the following facts are discovered: 41% of the athletes are football players, 52% are basketball players, and 35% of the athletes play both football and basketball. An athlete is chosen at random from the high school: what is the probability that the athlete is either a football player or a basketball player
Answer:
0.58 = 58% probability that the athlete is either a football player or a basketball player
Step-by-step explanation:
We solve this question treating the probabilities as Venn's sets.
I am going to say that:
Event A: Athlete is a football player.
Event B: Athlete is a basketball player.
41% of the athletes are football players:
This means that [tex]P(A) = 0.41[/tex]
52% are basketball players
This means that [tex]P(B) = 0.52[/tex]
35% of the athletes play both football and basketball.
This means that [tex]P(A \cap B) = 0.35[/tex]
What is the probability that the athlete is either a football player or a basketball player
This is [tex]P(A \cup B)[/tex], which is given by the following equation:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]. So
[tex]P(A \cup B) = 0.41 + 0.52 - 0.35 = 0.58[/tex]
0.58 = 58% probability that the athlete is either a football player or a basketball player

c. Solve Renard’s system of equations to find the number of bags of Carmel and number of bags of taffy that Ariel bought.
d. How you can verify that your solution is correct?
Answer:
20 taffy bags and 15 caramel candy bagsStep-by-step explanation:
Given:
t = the number of taffy bagsc = the number of caramel bagsNumber of taffy's are 5 more than caramel bagsTaffy bags weigh 8 ounces and caramel bags weigh 16 ouncesTotal weight is 400 ouncesEquations:
t = c + 5 (the difference in number of bags)8t + 16c = 400 (the weight of the bags)Simplify the second equation by dividing all terms by 8:
t + 2c = 50Substitute t and solve for c:
c + 5 + 2c = 503c = 50 - 53c = 45c = 45/3c = 15Find the value of t:

How can we get system B for system A?
And
Are the systems equivalent?
Answer: Subtract the equations in system A.
=============================================================
Explanation:
The first equation of each system is the same, so we'll try to transform the second equation of system A into the second equation of system B.
There are probably a number of ways to do this, but the quickest way that I can see is to subtract the equations of each system.
For system A, notice how the x terms line up and subtract to 5x-4x = 1x = x. In that same system, we have the y terms subtract to y minus (-7y) = y-(-7y) = y+7y = 8y
So far we have x and 8y as the results. So the left side is x+8y, which matches with the x+8y in the second equation of system B. So far so good.
Now we subtract the values on the right hand sides of each equation of system A. We get 3-8 which turns into -5, which also matches with the -5 in the second equation of system B.
Overall, subtracting the two equations of system A leads to x+8y = -5, which is the second equation of system B.
