An engineer is designing three triangular traffic signs with a computer program. The vertices of Sign A are located at (2, 2) , (2, 12) , and (17, 7) . The vertices of Sign B are located at (4,4),(11, 19) and (18, 4) . The vertices of Sign C are located at (4, 8), (24, 1) , and (24, 15) . Put the signs in order from largest to smallest perimeter. Sign A Sign B Sign C
Answer:
sign C, sign B, sign A
Step-by-step explanation:
Given the vertices of triangular post A as (2, 2) , (2, 12) , and (17, 7). Let us find the length of side of the post using the formula for calculating distance between 2 points using the formula:
D = √(y₂-y₁)²+(x₂-x₁)²
For the coordinate (2, 2) , (2, 12)
S₁ = √(12-2)²+(2-2)²
S₁ = √(10)²+(0)²
S₁ = √100
S₁ = 10
For the coordinate (2, 2) , (17, 7)
S₂ = √(7-2)²+(17-2)²
S₂ = √(5)²+(15)²
S₂ = √25+225
S₂ = √250
S₂ = 15.8
For the coordinate (2, 12) , (17, 7)
S₃ = √(7-12)²+(17-2)²
S₃ = √(-5)²+(15)²
S₃ = √25+225
S₃ = √250
S₃ = 15.8
Perimeter of sign A = S₁+S₂+S₃
Perimeter of sign A = 10+15.8+15.8
Perimeter of sign A = 41.6
FOR SIGN B with coordinate of vertices (4,4),(11, 19) and (18, 4)
For the coordinate (4, 4) , (11, 19)
S₁ = √(19-4)²+(11-4)²
S₁ = √(15)²+(7)²
S₁ = √225+49
S₁ = 16.6
For the coordinate (4, 4) , (18, 4)
S₂ = √(4-4)²+(18-4)²
S₂ = √(0)²+(14)²
S₂ = √196
S₂ = 14
For the coordinate (11, 19) , (18, 4)
S₃ = √(4-19)²+(18-11)²
S₃ = √(-15)²+(7)²
S₃ = √225+49
S₃ = 16.6
Perimeter of sign B = S₁+S₂+S₃
Perimeter of sign B = 14+16.6+16.6
Perimeter of sign B = 47.2
FOR SIGN C with coordinate of vertices (4, 8), (24, 1) , and (24, 15)
For the coordinate (4, 8) , (24, 1)
S₁ = √(1-8)²+(24-4)²
S₁ = √(-7)²+(20)²
S₁ = √49+400
S₁ = 21.2
For the coordinate (4, 8) , (24, 15)
S₂ = √(15-8)²+(24-4)²
S₂ = √(7)²+(20)²
S₂ = √49+400
S₂ = 21.2
For the coordinate (24, 1) , (24, 15)
S₃ = √(15-1)²+(24-24)²
S₃ = √(14)²+(0)²
S₃ = √196+0
S₃ = 14
Perimeter of sign C = S₁+S₂+S₃
Perimeter of sign C = 14+21.2+21.2
Perimeter of sign C = 56.4
Arranging in order from largest to smallest perimeter, Sign C(56.4), Sign B (47.2), sign A (41.6)

Step-by-step explanation:
How can we re-write the expression below into “friendlier” terms? 6 ∙ 29
options:
A. 6 ∙ (30 - 1)
B. 6 ∙ (16 + 13)
C. 6 ∙ (19 + 10)

How much interest will the account earn over this period?
Answer:
3250
Step-by-step explanation:
Multiply 5,000 times 6.5 percent
5000 X 6.5% = 3250
Big money Bank has an offer for new customers and the interest earned by the account over a period of time will be 3250.
What is Simple Interest?Simple interest is a quick and straightforward approach to figuring out how much interest has accrued on a sum of money. Interest is always applied to the main sum, and there is a constant rate of interest applied during the course of the calculation.
According to the question, the given information in the question is,
Principle amount, P = $5000
Rate, R = 6.5% and,
Time, T = 10 years
Make use of the simple interest formula, SI= [tex]\frac{P*R*T}{100}[/tex]
SI = [5000 × 6.5 × 10] / 100
SI = 325,000 / 100
SI = 3250
Hence, the interest earned by the account in this period will be 3250.

The 2 triangles formed are similar to the given triangle and to each other.
Δ ADB ~ Δ BDC
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{DB}{DC}[/tex] = [tex]\frac{AD}{BD}[/tex] , substitute values
[tex]\frac{10}{4x}[/tex] = [tex]\frac{x}{10}[/tex] ( cross- multiply )
4x² = 100 ( divide both sides by 4 )
x² = 25 ( take the square root of both sides )

The length of a rectangle is 6 inches longer than the width. The perimeter of the rectangle is eight times the width. What is the width of the rectangle?
Answer:
The width is 3 inches.
Step-by-step explanation:
First, let's identify our variables.
L=Length
W=Width
P=Perimeter
P=2W+2L
We know that L=W+6
We can substitute L for W+6, and we can substitute P for 8W, which gives us the equation:
8W=2W+2(w+6)
If you go through all the steps to isolate the variable W, you'll end up with W=3

Michael has 2 liters of a 10% solution. How much of a 17% solution would he need to add to get a 15% solution?
Answer:
5 liters
Step-by-step explanation:
Let x represent the number of liters of the 17% solution, and represent the percentages as decimal values:
0.1(2) + (0.17)(x) = 0.15(x + 2)
Simplify:
0.2 + 0.17x = 0.15x + 0.3
Solve for x:
0.17x = 0.15x + 0.1
0.02x = 0.1
x = 5
So, you would need 5 liters of a 17% solution to get a 15% solution

A) vehicle 1 is traveling at greater speed
B) vehicle 2 is traveling at a greater speed
C) vehicle 1 and 2 are traveling at the same speed
D) there is not enough information to determine which vehicle is traveling at a greater speed
========================================================
Explanation:
Let's find the slope of the graph
m = (y2-y1)/(x2-x1)
m = (120-80)/(3-2)
m = 40/1
m = 40
Each time x goes up by 1, y goes up by 40.
Vehicle 1 travels 40 miles for each hour, ie, its speed is 40 mph.
-------------
Now find the slope of the table
m = (y2-y1)/(x2-x1)
m = (240-150)/(8-5)
m = 90/3
m = 30
Vehicle 2's speed is 30 mph.
We see that Vehicle 1 is traveling 10 mph faster compared to Vehicle 2.
