Answer:
9.103
10. 77
11.60
12. 6.4
13. 20
14. 36
Step-by-step explanation:
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
180 - (47 + 30) = 103
DEG = 180 - 103 = 77 angles on a straight line equals 180
An equilateral triangle has all 3 sides equal
if the sum of angles in a triangle is 180 degrees, each angle measures 180 / 3 = 60
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
5² + 4² = 41
squareroot of 41 = 6.4
b : √(25² - 15²) = 20
√(60² - 48²) = 36
5.5 • 5= 27.5+27.5+65+65+71.5+71.5=328
13•5=65
13•5.5=71.5
THE ANSWER IS 328
Step-by-step explanation:
EZ = $0.15/min...eqn 1
Go = $40 + $0.05/min...eqn 2
let x be no of minutes then combine both eqns...
=> 0.15x = 40 + 0.05x...eqn 3
=> 0.1x = 40
x = 400
thus at 400mins both plans are equal
at 200mins go wit EZ...
total bill = $0.15 × 200 = $30.00
