Answer:
AB=8cm
Step-by-step explanation:
Since ABC is a right angled triangle,
Using pythagoras theorem,
h²=p²+b²
or, BC²=AC²+AB²
or, 17²=15²+AB²
or, 289=225+AB²
or, 289-225=AB²
or, AB² = 64
so, AB=8 cm
<h3>Given:</h3>
angle CED = 45°
angle EDC = x
angle DCE = 2x
<h3>To Find:</h3>
The value of x.
<h3>Angle Sum Property:</h3>
The sum of all the Interior Angles of a triangle is 180°.
<h3>Solution:</h3>
x + 2x + 45° = 180°
or, 3x = 180° - 45°
or, 3x = 135°
or, x = 135/3 = 45°
<h2>Answer:</h2>
The value of x is 45°.
The ordering cost using the Lot-for-Lot method is 900.06.
<h3>How to calculate the cost? </h3>
The ordering cost using the Lot-for-Lot method will be calculated thus:
C = Q/2(H) + D)Q(S)
C = 450/2(4) + 100/450(3)
C = 450(2) + 30/45
C = 900 + 0.7
C = 900.7
The ordering cost using Wagner-Whitin algorithm will be:
= 300 + 900 + 300 + 1700 + 2150 + 600
= 5750
The ordering cost using fixed order quantity will be:
= 6/(300 + 450 + 100 + 450 + 450 + 100)
= 6/1850
= 0.00324
