Answer:
528 birds
Step-by-step explanation:
100%-15%= 85% = .85
1400 (.85)^6
= 528
Answer:
55
Step-by-step explanation:
Divide 715/13 and the quotient is the answer.
The area of a circle by definition is given by:
A = pi * r ^ 2
Where,
r: radius
Substituting the values we have:
A = (3.14) * (15) ^ 2
A = 706.5 mm ^ 2
Answer:
The approximate area of the compass is:
A = 706.5 mm ^ 2
Answer:
After 12 years the investment will be worth $5145.
Step-by-step explanation:
The formula used for compounded interest is:
A = P(1+r/n)^nt
where,
A = future value
P = Principal Amount
r = interest rate
n = no of times interest is compounded
t = time
In the question given:
A=?
P = $2100
r = 7.75% or 0.0775
n = 1
t= 12
A= 2100*(1+0.0775/1)^1*12
A= 2100 *(1+0.0775)^12
A= 2100 *(1.0775)^12
A= 2100 * 2.45
A= 5145
So, after 12 years the investment will be worth $5145.
