S is inversely proportional to t When s = 0.5, t = 7 Work out s when t = 0.8
1 answer:
Given:
s is inversely proportional to t.
When s = 0.5, t = 7.
To find:
The value of s when t=0.8.
Solution:
s is inversely proportional to t.
...(i)
Where, k is the constant of proportionality.
Putting s=0.5 and t=7, we get
Putting k=3.5 in (i), we get
This is the equation of proportionality.
Putting t=0.8, we get
Therefore, the value of s is 4.375 when t=0.8.

<h3>What are Algebraic equations?</h3>With one exception, algebraic equations are essentially algebraic expressions.
An = sign is required in all algebraic equations.
No matter what kind of equation it is, all equations use the = sign.
The next topic is algebraic expression, which lacks the operators =,,, >, and.
To put it simply, there is no comparison between two terms in an algebraic statement.
Algebraic expressions frequently use terms like polynomial and square root.
So you now recognize the distinction between the two?
1) An algebraic equation has the symbol =, and 2) an algebraic expression lacks any comparison symbols (such as > and =).
As per the question:
55/9 + 10/3 = 85/3
(55m+30m)/9 = 85/3
85m/9 = 85/3
85m = (85*9)/3
85m = 85*3
m = (85*3)/85
∴ m = 3
