We have to find the simplest ratio between length, breadth and the height.
Here,
- Length = 10 cm
- Breadth = 15 cm
- Height = 25 cm
Note:
- Always check the units first.
- Then find the HCF of the numbers to simplify them into the simplest ratio.
So,
HCF of 10, 15 and 25 is 5. Cancelling with respect to 5.
Then, the ratio will be 2:3:5 (Option A)

Alrighty
P=2000
A=2543
t=4


solve

divide both sides by 2000

take ln of both sides




divide both sides by 4

use your calculator
0.060049=r
convert to percent
that is about 6%
the interest rate is 6%
Answer:
1.523
Explanation:
cos (-t) = 0.983
-t = cos^1(0.983)
t = cos^1(-0.983)
t = 1.523
