Step-by-step explanation:
height = constant / width
that means
constant = height × width.
so, we only need to multiply the 2 coordinate numbers of one of the points.
the easiest is clearly (0.8, 1).
0.8 × 1 = 0.8
so, the constant is 0.8
Answer:
16%
Step-by-step explanation:
Solution for 0.40 is what percent of 2.50:
0.40:2.50*100 =
(0.40*100):2.50 =
40:2.50 = 16
Given:
Amount = Rs. 9,144
Time = 3 years.
Rate of simple interest = 9%
To find:
The principal value.
Solution:
The formula for simple interest is:

Where, P is principal, r is the simple rate of interest, and t is the number of years.
Putting
in the above formula, we get



We know that,



Divide both sides by 1.27, we get


Therefore, the principal value is Rs. 7200.
