If 80% is 60 marks, what is full marks?

1 answer:

4 0

Full marks is 75.

Explanation:
Let's set up a proportion to better understand the problem

80% 100%
----- = ----
60 ?

Since we want to know what is FULL, we know we have to find 100%. Now, to get from 80 to 100, we multiply by 1.25 (100/80 = 1.25. After we know that, all we have to do is do the same to 60. So we multiply 60 by 1.25 as well, to get 75. Therefore, full marks is 75.

Answer:

<em>The x-coordinate is changing at 10 cm/s</em>

Step-by-step explanation:

<u>Rate of Change</u>

Suppose two variables x and y are related by a given function y=f(x). If they both change with respect to a third variable (time, for instance), the rate of change of them is computed as the derivative using the chain rule:

$\displaystyle \frac{dy}{dt}=\frac{dy}{dx}\cdot \frac{dx}{dt}$
