Answer:
28.75 m.
Step-by-step explanation:
It is given that a ball is dropped from a height of 10 meters. Each time it bounces, it reaches 50% of its previous height. So,
For first bounce the vertical distance
For next bounce ball has to travel up and down by 50% of previous distance, i.e., 10 m.
For second bounce the vertical distance
Similarly,
For third bounce the vertical distance
For fourth bounce the vertical distance
For fifth bounce the vertical distance
The total vertical distance down the ball has traveled when it hits the the 5th time is
Therefore, the total vertical distance down the ball has traveled when it hits the the 5th time is 28.75 m.
Answer:
(2,5)
Step-by-step explanation:
Answer:
a) $175 b) It will be $126
Step-by-step explanation:
Cost price of 3 games= $140
Let the original price of games= $ x
Discount is given= 30%
According to question
x = $140
x = $140
x ×0.8= $140
x= $
x= $175
Hence, the original price of games $ 140
(b) If Sam had given a discount of 20%
Again a discount = 10%
The price of games=$ 140
Now, the selling price will be= 175×
Now, the selling price will be= $ 126
Hence, the price will be different.
