309124 clips were shared among Lisa, Mary, and Ria. Lisa got 64 clips and the rest was divided between Mary and Ria so that Mary got twice as many clips as Ria. How many clips did Mary get? Anton planted a tree 24 cm tall in his garden. Each week it grew by 12 cm. How many weeks would it take the plant to grow to 3 metres?
Answer (1)
To solve the question about the number of clips Mary received, let's break down the information given:
Total clips available : 309124 clips
Clips given to Lisa : 64 clips
Clips remaining for Mary and Ria : 309124 - 64 = 309060 clips
Mary received twice as many clips as Ria .
Let's assume the number of clips Ria got is x . So, Mary would have twice that amount, which is 2 x .
The equation for the remaining clips shared between Mary and Ria will be:
x + 2 x = 309060
3 x = 309060
To find x , divide both sides by 3:
x = 3 309060
x = 103020
Thus, Ria got 103020 clips. Since Mary's amount is 2 x :
2 x = 2 × 103020 = 206040
So, Mary received 206040 clips .
Now, let's calculate how long it takes for Anton's plant to grow:
Initial height of the plant : 24 cm
Growth per week : 12 cm
Target height : 3 metres, which is equivalent to 300 cm
To find out how many weeks it will take for the plant to reach 300 cm, we calculate:
First, find the required growth:
300 − 24 = 276 cm needed for growth
Since the plant grows 12 cm each week, we find the number of weeks by dividing:
12 276 = 23
So, it would take 23 weeks for the plant to grow to 3 metres.
