The answer is: "2.5 years" .

Note: I = P * r * t ; { " Interest = Principal * rate * time "} ;
→ Solve for "t" {"time", in years} ;
Divide each side of the equation by "{P * r}" ;
to isolate "t" on one side of the equation ;
→ I / (P * r) = {P * r * t) / (P * r} ;
to get: " I / (P * r) = t " ;
↔ t = I / (P * r) ;
Given: I = $450 ;
<span>P = $2400 ;
r = 7.5% = 7.5/100 = 0.075 ;
Plug in these values into the formula to solve for the time, "t" :
</span>→ t = I / (P * r ) ;
= $450 / (<span>$2400 * 0.075) ;
= </span>$450 / ($2400 * 0.075) ;
= $450 / $180 ;
= $45 / $18 ;
= ($45 ÷ 9) / ($18 ÷ 9)
= $5 / $2 ;
= 2.5 ;
→ t = 2.5 years.

The answer is 4 1/2 (four and a half).
Answer:
72 cubic inches
Step-by-step explanation:
Volume of cone =
--1
Volume of cylinder =
--2
We are given that a cylinder should fit exactly inside the cone
On comparing 1 and 2 we can see:

Since we are given the volume of cone is 24 cubic inches .
So, 


Hence the volume of cylinder is 72 cubic inches
Option D is correct.
Answer:
s = 10
Step-by-step explanation:
Given s is inversely proportional to t , then the equation relating them is
s =
← k is the constant of proportion
To find k use the condition when s = 0.6, t = 5
0.6 =
( multiply both sides by 5 )
3 = k
s =
← equation of proportion
When t = 0.3, then
s =
= 10
