Buying cost of the investment or the principle amount = $1000
Time, n = 5 years
Selling cost of investment or amount received = $1700
Now,
the formula for compound interest is given as:
here, r is the rate of interest
on substituting the respective values, we get
or
(1 + r)⁵ = 1.7
or
1 + r = 1.11196
or
r = 0.11196
or
r = 0.11196 × 100% = 11.196%
Answer:
8 ft
Step-by-step explanation:
The area (A) of a triangle = bh
where b is the base and h the perpendicular height
Using b = 20 and h = 12, then
A = 0.5 × 20 × 12 = 120 ft²
Using b = 30 and perpendicular height = h, then
0.5 × 30 × h = 120
15h = 120 ( divide both sides by 15
h = 8
