I'm having a hard time with this. A new housing development extends 4 miles in one direction, makes a right turn, and then con-

tinues for 3 miles. A new road runs between the beginning and ending points of the development. What is the perimeter of the triangle formed by the homes and the road? What is the area of the housing development?

Answer:

perimeter = 12 miles

area = 6 square miles

Step-by-step explanation:

Since it makes a right triangle, use the Pythagorean Formula.

3^2+4^2=c^2

9+16=c^2

25=c^2

5=c, so the hypotenuse of the right triangle is 5.

Perimeter = 3+4+5 = 12 miles

area = 1/2bh (1/2 base times height)

=1/2x3x4

=6

Area = 6 square miles

liq [111]
Here, scale factor = 1 : 20
On scale, Tree's height = 6 3/4 = 27/4

Height of Actual Tree = 27/4 * 20 = 27 * 5 = 135

In short, Your Answer would be 135

Suppose the average yearly salary of an individual whose final degree is a​ master's is ​$(blank) thousand less than twice that
cupoosta [38]

Complete question :

Suppose the average yearly salary of an individual whose final degree is a​ master's is ​$41 thousand less than twice that of an individual whose final degree is a​ bachelor's. Combined, two people with each of these educational attainments earn ​$118 thousand. Find the average yearly salary of an individual with each of these final degrees.

Answer:

Bachelors = $53000

Masters = $65000

Step-by-step explanation:

Given that :

Let Salary of bachelor's degree holder = b

Salary of Master's degree holder = 2b - 41000

Master's + bachelor's salary = $118,000

Hence,

2b - 41000 + b = 118,000

3b = 118000 + 41000

3b = 159000

b = 159000 / 3

b = $53,000

Bachelor's degree salary = $53,000

Master's degree salary ; 2b - 41000

2(53000) - 41000 = 65000

20 POINTS!In this unit, you worked with geometric proofs. A proof is a logical sequence of justified conclusions that lead from
Masja [62]
Not only in mathematics, scientific proof also are required in the other field of science. Also maths proofs are of particular structure, containing steps and logics. So proving is like doing science, it is science. That's why it is important to prove. 
An inaccurate proof leads to errors, or stating results that are not accurate. 
Example 1:
If the derivative of a function is negative, then the function is decreasing. 
Example 2:
The sum of the measures of the angles of any triangle is 180°.
Example 2:
Given a triangle whose vertices are on a circle and one side is the 
diameter of the triangle, then the triangle is right angled.
