Step-by-step explanation:
Given
m cups of water = p cups of rice
Required
Cups of water required for p + 2 cups of rice
<em>The question shows a direct proportion between cups of rice and cups of water.</em>
<em>So, the first step is to get the proportionality constant (k)</em>
<em />
This is calculated using the following expression;
Where k represents cups of water and p represents cups of rice
Make k the subject of formula
Let x represents cups of water when cups of rice becomes p + 2;
k becomes:
Equate both expressions of k; to give
Multiply both sides by p + 2
<em>Hence, the expression that represents the cups of water needed is </em><em></em>
Answer: 32
Step-by-step explanation:
Given: The energy needed for 1 hour of running for an adult
Therefore. the energy needed for seven hours of running=
Since, he energy released by metabolism of 1 average candy bar
