Step-by-step explanation:
Final amount that Kate wants to have (A) = $25000
Time for which the money needs to be invested (T) = 16 years
Rate of interest that Kate will get per year (R) = 6%
Let us assume the principal amount (P) = x
Then
A = P (1 + RT)
25000 = x[1 + {(6/100) * 16}]
25000 = x[1 +(96/100)]
25000 = x[196/100]
196x = 25000 * 100
x = 2500000/196
= 12755.10 dollars
So the principal amount that needs to be invested is $12755.10.
Answer:
4 : 25
Step-by-step explanation:
Given the ratio of 2 similar figures = a : b, then
ratio of areas = a² : b²
Given the similarity ratio = 2 : 5, then
ratio of areas = 2² : 5² = 4 : 25
Answer:
Step-by-step explanation:
a = 6
c = 6
b = 13
ac = 6 * 6 = 36
4 and 9 multiply to 36 and 4 and 9 add to 13
