Answer:
see explanation
Step-by-step explanation:
Calculate AC and AB using the distance formula
d = 
with (x₁, y₁ ) = A(1,8) and (x₂, y₂ ) = C(4,2)
AC = 
= 
= 
=
=
= 3
Repeat with
(x₁, y₁ ) = A(1, 8) and (x₂, y₂ ) = B(2, 6)
AB = 
= 
= 
= 
So AB =
and AC = 3
Thus
AC = 3AB
Answer:
14%
Step-by-step explanation:
28/200 = x/100
x = 14
Answer:
Explanation:
Let x be the age of the person who enter the room
(18 + 25 + 18 + 21 + 16 + x)/6 = 25
(77 + x)/6 = 25
77 + x = 25(6)
77 + x = 150
x = 150 - 77
x = 73
Answer: 9 inches.
Do the pythagorean theorem to find your answer.
Formula: a^2 + b^2 = c2
12 = b
15 = c
a^2 + 12^2 = 15^2
Simplify the equation
a^2 + 144 = 225
Subtract 144 on both sides.
a^2 = 81
Square root of 81 is 9.
36
