Answer:
∠ 2 = 60°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles fro 180° for ∠ 2, that is
∠ 2 = 180° - (57 + 63)° = 180° - 120° = 60°
Answer:
1x3=3
0.4x3=1.2
0.5x1=0.5
0.4x0.5=0.2
Step-by-step explanation:
The 9 combinations that exist for two movements:
R,R
R,L
R,U *
L,R
L,L
L,U
U,R *
U,L
U,U
Walker would only be able to make it to (1,1) with only 2 of these combinations.
So if he were only allowed to make two movements, his chances of arriving at (1,1) would be 2/9.
Answer:
1. 4.5 g
2. 56.25 g
Step-by-step explanation:
3 % substance solution means :
3 g of dry substance is present in 100 g of solution.
By unitary method:
The weight of dry substance in 1 g of solution = 
The weight of dry substance in 150 g of solution = 
Let the weight of solution be w.
8 % solution contains 8 g dry substance in 100 g.
We have to find the weight of the solution(w) which contains 4.5 g of dry substance.
