Answer:
20 years
Step-by-step explanation:
Using the formula; A = P(1 + r)^t
We can plug in the known to find t
400 = 220(1.03)^t
then solve for t;
1.818 = 1.03^t
Introducing In
In 1.818 = t × In (1.03)
t = 20.225
t = 20 years to the nearest year
Answer:
<h2>
29.30cm^3</h2>
Step-by-step explanation:
If the two cone are similar then the heights are the same
let us find the height of the bigger cone

For the bigger cone
r= 3cm
v= 66cm^3

For the smaller cone
r=2cm
v=?
h=7cm

the 3rd vertex is on the x axis line which means Y =0
since the longer leg is twice as long as the shorter leg and the length of the shorter leg is a, then twice the length would be 2a ( 2 times a)
so the 3rd vertex is (2a,0)
18 hours cause 95/5 =19 then 342/19 is 18!
-8 I believe is the answer
