Answers
Answer:
Right Triangles:
(5.1, 6.8, 8.5) and (12.5, 30, 32.5)
Not Right Triangles:
(2.2, 4.5, 6.7) and (4.7, 8.6, 10.7)
Step-by-step explanation:
I solved by using the pythagorean theorem (a^2+b^2=c^2)
Plug the side lengths in, the largest side length is always c. If the equation comes out true, it is a right triangle.

A pound of chocolate costs 8 dollars. Kala buys p pounds. Write an equation to represent the total cost c that Kala pays.
Answers
Answer:
8p=c
Step-by-step explanation:
For questions like this, it isn't asking for a numerical answer or anything complicated. It's mainly just using common sense and figuring out what you would do if you had actual numbers instead of variables. You would multiply the amount of pounds (p) by the cost per pound of $8, and that would be your answer (c). I hope I could help.

Answer:
they are supplementary so
180-101
=79 degrees
Answer:
9.
Angle 1 and angle 2 are supplementary angles, which means they add up to 180. Thus, as angle 1 is 101 degrees, angle 2 is 180-101 degrees, which is 79 degrees.
8. complementary angles are angles that add up to 90 degrees. The picture shows us that angle AGB is 90 degrees because there is a square symbolizing it. Therefore AGE also must be 90 degrees because it is congruent to angle AGB. The two angles that makeup AGE are AGF and FGE. Therefore, it is the first option.
7.
Adjacent angles are two angles that have a common vertex and a common side but do not overlap. The only pair of angles given that are next to each other is the second option, DGE and DGC.

Vector V has components of (6,9) determine the angle in degrees that vector vee makes with the X axis
Answers
Given :
Vector V has components of (6,9).
To Find :
The angle in degrees that vector V makes with the x-axis.
Solution :
The x-component of vector is, x = 6 units.
The y-component of vector is, y = 9 units.
So, the angle the vector makes from the horizon is :
[tex]\theta = tan^{-1}{\dfrac{y}{x}}\\\\\theta = tan^{-1}{\dfrac{9}{6}}\\\\\theta = 56.31^o[/tex]
Hence, this is the required solution.

Assume you have five candidates for recruitment and their scores on interview and job knowledge test is below. The interview is measured on scale of 1-25 points and job knowledge is measured on a scale of 1-100 points. Based on the scores of these two tests for the five candidates, who would you select as a finalist. Please note that you need to use the method we used in class to find out the finalist for selection. Describe the answer with the appropriate calculations as we did in the exercise in class.
Answers
Answer: Hi your question is incomplete below is the missing part
Candidate Interviewscore Job Knowledge Test Score
Frank. 14 89
Sally 21 77
Lilly 20 75
Peter 17 82
Jordyn 19 80
Answer : Select Sally because she has the highest Test score
Step-by-step explanation:
For Franck :
Interview score / 25 = 14 / 25 = 0.56
Job knowledge score = 89 /100 = 0.89
Test score = 0.56 + 0.89 = 1.45
For Sally
interview score = 21 / 25 = 0.84
Jon knowledge = 77 / 100 = 0.77
Test score = 0.84 + 0.77 = 1.62 ( Highest test score )
Repeat the same procedure for Lilly , Peter and Jordyn
Lily test score = 1.55
Peter test score = 1.5
Jordyn test score = 1.56
conclusion : select Sally as a Finalist

Answer:
Hey! Sorry im too late lol but here-
Step-by-step explanation:
Example of tangent in the real world-
When a stone gets tied at one end of a string & the other end is rotated, then the stone will form a circle.
How you know the tangent and radius are perpendicular:
The radius is formed vertically and is completely straight, while the tangent is completely straight but horizontal. You can draw a right triangle angle between the radius and tangent line by adding a third line, and a right angle is 90 degrees. So, this forms a perpendicular line.

Part A: The path of the ball in relation to the curved path of the thrower
Part A: The path the ball takes is perpendicular to the hand, bat or feet at the point of last contact
Reason for the selection:
Part A
A real world example of tangents is the direction of a ball immediately it is released and the circular path of the motion, that provides the force input that is given to the ball to cause it to move in the required direction
The tangent is the path the ball takes immediately it is moving without contact to the bat, hand or feet that causes it to move
The circular path is the motion of the hand, leg, bat or feet that makes before the ball is released
The radius is the hand, leg, or bat that rotates in a circular path, so as to move the ball
Part B
How the radius is perpendicular to the tangent
The radius, such as the leg kicking a ball is perpendicular to the tangent of the which is the path of the ball because a kick to send the ball into air, the orientation of leg at the point the ball leaves is perpendicular to the angle of elevation with which the ball is launched
