Answer:
1.6
Step-by-step explanation:
Given :
X/4 = 2/5
To solve for X ;
We can use cross multiplication ; multiply opposite values :
X * 5 = 2 * 4
5X = 8
To isolate X ;
Divide both sides by 5
5X/5 = 8/5
X = 8/5
X = 1.6
Answer:
h = 3V/(πr²)
Step-by-step explanation:
You are asked to solve a one-step linear equation for h.
<h3>Solution</h3>
The "one step" is to divide by the coefficient of h.
__
<em>Additional comment</em>
The equation is "linear" because the variable of interest is h. It has an exponent (degree) of 1. The other "variables" are treated as though they were constants. The equation is conceptually no different from ...
2 = (5/3)h
which you solve by dividing by 5/3 (or multiplying by 3/5).

Now put in the data:
Answer:
80 feet
Step-by-step explanation:
c=d
Substitute 250 in for circumference
250=d
Divide by or 3.14
d=79.617...
So, the diameter is approximately 80 feet
