Answer:
She paid $251.40 in interest only for the loan.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this problem:
So
She paid $251.40 in interest only for the loan.
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.
