A) -20a
B) -18a
C) 6a
D) 18a
E) 20a
With steps please
Answers
Answer:
D) 18a
Step-by-step explanation:
y - x
= 4x - x (plug y = 4x)
= 3x
= 3(2z) (plug x = 2z)
= 6z
= 6(3a) (plug z = 3a)
= 18a

x = 16
Step-by-step explanation:
Supplementary angles = 180
K + L = 180
137 + 3x - 5 = 180
132 + 3x = 180
3x = 180 - 132
3x = 48
x = 48/3
x = 16

Answers
Answer:
The Identity Property of Zero, also called the Additive Identity Property, states that if you add 0 to any number, the result will be that number. Likewise, if you subtract 0 from any number, the result will be that number. Believe it or not, this works for all real numbers.

Workers at the Pythagorean Construction Company are building a new house. They need to make sure that proper right triangles are formed to ensure that a safe house is built. What statement should the builders use to ensure that right triangles are formed? If the sum of the two shorter sides equals the longest side, then the triangle is a right triangle. If the sum of the squares of the two longer sides equals the square of the shortest side, then the triangle is a right triangle. If the sum of the squares of the two shorter sides equals the square of the longest side, then the triangle is a right triangle. If the difference of the squares of the two shorter sides equals the square of the longest side, then the triangle is a right triangle.
Answers
Answer: C.) If the sum of the squares of the two shorter sides equals the square of the longest side, then the triangle is a right triangle.
Step-by-step explanation: i hope this helps! :)
The correct statement is (C)
What is Pythagoras theorem?The Pythagoras theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides.
The Pythagoras theorem equation is expressed as, c2 = a2 + b2, where 'c' = hypotenuse of the right triangle and 'a' and 'b' are the other two legs. Hence, any triangle with one angle equal to 90 degrees produces a Pythagoras triangle and the Pythagoras equation can be applied in the triangle.
example:
The hypotenuse of a right-angled triangle is 16 units and one of the sides of the triangle is 8 units. Find the measure of the third side using the Pythagoras theorem formula.
Given : Hypotenuse = 16 units
Let us consider the given side of a triangle as the perpendicular height = 8 units
On substituting the given dimensions to the Pythagoras theorem formula
Hypotenuse2 = Base2 + Height2
162 = B2 + 82
B2 = 256 - 64
B = √192 = 13.856 units
So, Using the definition of Pythagoras theorem
the statement would be
If the sum of the squares of the two shorter sides equals the square of the longest side, then the triangle is a right triangle.

Write an application that determines which employee will be selected each week for the next 52 weeks. Use the Math.random() function explained in Appendix D to generate an employee number between 1 and 30; you use a statement similar to:
Answers
Answer:
In Java:
import java.util.Random;
public class Main{
public static void main(String args []){
int Employee;
for(int weeks = 1;weeks<=52;weeks++){
Employee = 1 + (int)(Math.random() * 30);
System.out.println("Week "+weeks+" selected employee: "+Employee);
}
}
}
Step-by-step explanation:
This imports the Random package into the program
import java.util.Random;
public class Main{
public static void main(String args []){
Declare employee as integer (represents employee 1 to 30)
int Employee;
Iterate from week 1 to 52
for(int weeks = 1;weeks<=52;weeks++){
Randomly select an employee from 1 to 30 (inclusive)
Employee = 1 + (int)(Math.random() * 30);
Print the selected employee
System.out.println("Week "+weeks+" selected employee: "+Employee);
}

Fresh air, with the CO2 concentration of 400 ppm starts flowing into the room at the rate of 40 m^3/min. The pressure in the room is constant, so an equal amount of stale air flows out as fresh air flows in, and the CO2 is evenly distributed.

What is the original price of a pair of shoes if there is a 5% discount and the sale price is $47.03?
Answers
Answer:
$49.51
Step-by-step explanation:
100-5(the discount) =95%equate 95%=47.03 what about 100%(100%×47.03)÷95$49.51 ansThe original price of the shoes is $49.50.
What is the discount?The pricing scheme in which the cost of a thing (or service) is less than its marked price listed price is referred to as a "discount." Simply put, a discount represents a percentage off the advertised price. In consumer interactions, a discount is a type of product price reduction where customers have suggested a percentage of rebates on various goods to increase sales.
Given discount = 5%
sale price = $47.03
to find original price
discount is given by
Discount (percentage) = (List Price - Selling Price)/ List Price x 100
5% = 1 - SP/LP
SP/LP = 1 - 5%
47.03/LP = 1 - 5/100
LP = (47.03 x 100)/95
LP = $49.50
Hence the original price of the shoes is $49.50.
