Answer: 64
Step-by-step explanation:
By definition, a perfect square is the square of a whole number.
The information given in the problem that you must keep on mind is:
- The number has two digits.
- The number is a perfect square ( Is obtained by squaring a whole number).
- The sum of its two digits is 10.
The number 64 is formed by the digit 6 and the digit 4. The sum of both digits is:
![6+4=10](https://tex.z-dn.net/?f=6%2B4%3D10)
The number 64 can be written as:
![64=8*8=8^2](https://tex.z-dn.net/?f=64%3D8%2A8%3D8%5E2)
Then, it is perfect square.
Match up each of the corresponding sides, and simplify the ratio.
That ratio is the scale factor.

Answer:
19 years
Step-by-step explanation:
The compound interest formula tells you the future value of principal P invested at annual rate r compounded n times per year for t years is ...
A = P(1 +r/n)^(nt)
Solving for t, we get ...
t = log(A/P)/(n·log(1 +r/n))
Using the given values, we find t to be ...
t = log(2.13022)/(4·log(1 +0.04/4)) ≈ 19.000
The investment will be worth $213,022 after 19 years.
Answer:
c=79/34
Step-by-step explanation:
First, let's set up the equation:
"29 more than" is just
29+
"t" is
t
"equal to one" is
=1
put it all together to get
29+t=1
subtract 29 from both sides to get your answer:
t=-28
