svlad2 [7]
Theorem : If two similar triangles have a scale factor of a : b, then the ratio of their areas is a^2 : b^2<span>.
We have a</span>: b = 1: 1; then a^2 : b^2 = 1^2 : 1^2 = 1;

What is one-fourth of four sevenths
AlekseyPX
1/4  x 4/7
do the top numbers first. 1 x 4 is 4do bottom numbers next 4 x 7 is 28

that leaves you with 4/28. But you have to reduce.

4/28 = 2/14 = 1/7 (notice I just cut both the top and bottom numbers in half each time I reduced until I couldn't reduce any more).
So, final answer is 1/7

Answer:

  • 10%

Step-by-step explanation:

<u>Given:</u>

  • Borrowed amount P = Rs 100000
  • Time t = 3 years
  • Number of compounds n = 3
  • Interest I = Rs 33100
  • Rate r = ?

<u>Use formula:</u>

  • I = P(1 + r)³ - P

<u>Substitute values and solve for r:</u>

  • 33100 = 100000(1 + r)³ - 100000
  • 133100 = 100000(1 + r)³
  • (1 + r)³ = 133100/100000
  • (1 + r)³ = 1.331
  • 1 + r = ∛1.331
  • 1 + r = 1.1
  • r = 0.1  or 10%
