In the figure above, if PQRS is a parallelogram, then y-x=?
Correct Answer:
A: 30
Explanation:
In the figure above, if PQRS is a parallelogram, then y-x=? Correct Answer 30 In parallelogram corresponding angles are equal and consecutive angles supplementary (supplementary angles are two angles that add up to 180°), thus : 140 = 2y 2y + x = 180 y = 70 = > 140 + x = 180 = > x = 40 Now, y - x = 70 - 40 = 30 So, the answer choice is (a) 30

In each of the following questions, count the number of triangles and squares in the given figure.
Correct Answer:
C: 36 triangles , 9 squares
Explanation:
In each of the following questions, count the number of triangles and squares in the given figure. Correct Answer 36 triangles , 9 squares A Collection of 16 coins,each with a face value of either 10 paisa or 25 paisa, has a total face value of Tk. 2.35 How many of the coins have a face value of 25 paisa? We can let the number of 10 - paisa coins = d and the number of 25 - paisa coins = q. We are given that there are 16 total coins; thus, d + q = 16. We are also given that the total face value isTk.2.35, thus: 0.1d + 0.25q = 2.35 10d + 25q = 235 Isolating d in our first equation, we have d = 16 - q. We can substitute 16 - q for d in our second equation and we have: 10(16 - q) + 25q = 235 160 - 10q + 25q = 235 15q = 75 q = 5 There are 5 coins with a face value of 25 paisa.
