Answer:
The answer is the CD was for 3 years.
Step-by-step explanation:
First, write the equation.
I=Prt
Next, substitute the given values.
$198=$1,200×5.5%×t
Next, write the percent as a decimal.
$198=$1,200×0.055×t
Next, simplify.
$198=$66×t
Then, solve for t.
3=t
Answer:
r = 6
Step-by-step explanation:
Given that M is directly proportional to r³ then the equation relating them is
M = kr³ ← k is the constant of proportionality
To find k use the condition r = 4 when M = 160
k =
=
= 2.5, so
M = 2.5r³ ← equation of proportionality
When M = 540, then
540 = 2.5 r³ ( divide both sides by 2.5 )
216 = r³ ( take the cube root of both sides )
r =
= 6
