Split up each force into horizontal and vertical components.
• 300 N at N30°E :
(300 N) (cos(30°) i + sin(30°) j)
• 400 N at N60°E :
(400 N) (cos(60°) i + sin(60°) j)
• 500 N at N80°E :
(500 N) (cos(80°) i + sin(80°) j)
The resultant force is the sum of these forces,
∑ F = (300 cos(30°) + 400 cos(60°) + 500 cos(80°)) i
… … … + (300 sin(30°) + 400 sin(60°) + 500 sin(80°)) j N
∑ F ≈ (546.632 i + 988.814 j) N
so ∑ F has a magnitude of approximately 1129.85 N and points in the direction of approximately N61.0655°E.
Answer: 1,3,5
Step-by-step explanation:
The question is incomplete :
However, assume Number of cups of flower 10
Number of flour cups for each pie 1/4
Answer:
8
Step-by-step explanation:
Number of cups of flower = 10
Number of flower cups per crust pie = 1/4 cups
Since, the cups of flower was divided equally into to 5 containers;
Number of flower cups per container :
10 / 5 = 2
Each container has 2 cups of flower each.
1 container was used in making crust pie :
The number of crust pies made is:
Cups of flower in container / cups of flower per crust pie
= 2 ÷ 1/4
= 2 * 4 /1
= 8 crust pies
Answer:
90%
Step-by-step explanation:
50x2=100, 45x2=90, if 45/50=90/100, thats your %
