Answer: 30 feet per second
========================================
x = diameter, y = speed of water
y varies inversely with respect to x, so, y = k/x for some constant k
If x = 0.6 and y = 5 pair up, then y = k/x turns into 5 = k/0.6 which solves to k = 3 when you multiply both sides by 0.6
So the equation y = k/x turns into y = 3/x
Now plug in the diameter x = 0.1 to find the speed to be...
y = 3/x
y = 3/0.1
y = 30 feet per second
Answer:
150
Step-by-step explanation:
The mathematical expression that represents the given statement is 4/(7-x)
<h3>Writing an Expression </h3>
From the question, we are to write a mathematical expression for the given statement
The given statement is
"4 is divided by the difference of 7 and a number."
First,
Let the number be x
"the difference of 7 and a number" means
7 - x
Thus,
"4 is divided by the difference of 7 and a number" is
4/(7-x)
Hence, the mathematical expression that represents the given statement is 4/(7-x)
