Answer:
The answer to your question is 20 feet
Step-by-step explanation:
Data
A = (-2, 1)
B = (4, 1)
C = (-2, -3)
D = (4, -3)
Process
1.- Calculate the distance from C and D
dCD = 
dCD = 
dCD = 6
2.- Calculate the distance from A to C
dAC = 
dAC = 
dAC = 4
3.- Calculate the perimeter
Perimeter = 2(dCD) + 2(dAC)
-Substitution
Perimeter = 2(6) + 2(4)
-Simplification
Perimeter = 12 + 8
-Result
Perimeter = 20 ft
Answer:
see explanation
Step-by-step explanation:
the perimeter is the sum of the 3 sides of the triangle
add the parts of the ratio 21 + 8 + 14 = 43
divide the perimeter by 43 to find the value of one part of the ratio
= 5 ft ← 1 part of the ratio, hence
21 parts = 21 × 5 = 105 ft
8 parts = 8 × 5 = 40 ft
14 parts = 14 × 5 = 70 ft
the 3 sides of the triangle are 105 ft, 40 ft and 70 ft
Answer:
x= −5±√−7 / −2 --> (No Real Solution)
Step-by-step explanation:
−x^2+5x−6−2=2−2
−x^2+5x−8=0
x= −(5)±√(5)2−4(−1)(−8) / 2(−1)
x= −5±√−7 / −2
Answer:
<h2>31 tickets</h2>
Step-by-step explanation:
Step one:
number of tickets sold
monday=14
tuesday=10
the number of tickets sold for Monday and Tuesday combined is
14+10= 24
step two:
we want to find how many tickets make 30%
so 30/100*24
0.3*24
=7.2 tickets,
Approximately 7 ticket
Therefore the total ticket is
14+10+7
=31 tickets
Let's calculate the slope of the A(3,1.5) and B(5, 2.5)
The formula of the slope m =(y₂-y₁)/(x₂-x₁)
m = (2.5 - 1.5)/(5 - 3)
m = (1)/(2) = 0.5
