Answer:
The distance between the posts is feet.
Step-by-step explanation:
In the attached figure, let DB and AC be the posts and let AD be the wire attached to the top of the posts.
BC is the distance between the posts and we need to find BC.
Note that BC = DE
Also, EC = DB = 8m and AE = AC - EC = 17 - 8 = 9 m.
Now, in the right triangle ADE,
= (24+9) (24-9)
= 33(15)
= (3 × 11) × (3 × 5)
Since DE = BC,
Hence, the distance between the posts is feet.
Answer:
344
Step-by-step explanation:
Number of coins added per day in the collection = 9
Number of coins in the collection after 22 days = 218
To find:
Number of coins in the collection after 36 days.
Solution:
First of all, let us find how many coins did he have initially.
Let the number of coins present initially with Wil =
Number of coins added per day = 9
Number of coins added after 22 days = 22 9 = 198
Therefore,
Number of coins present with Wil initially = 20
Number of coins added after 36 days = 36 9 = 324
Total number of coins after 36 days = Number of coins present initially with Will + Number of coins added = 324 + 20 = <em>344</em>
