<em><u>The equation to the rate of increase of the radius in terms of the radius is:</u></em>
<em><u>Solution:</u></em>
<em><u>The rate of increase (R) of the radius (r) in meters per second is inversely proportional to the radius</u></em>
Therefore,
<em><u>The radius is increasing at 1400 meters per second when the radius is 10 meters</u></em>
r = 10 m
R = 1400 meter per second
<em><u>Substitute in eqn 1</u></em>
<em><u>Substitute k = 14000 in eqn 1</u></em>
Thus the equation is found
12+4x=5x
x=12

Answer:
4
Step-by-step explanation:
20 x 4 = 80
so 1 per 20 minuets,and 4, 20 min. magazines would mean he needs 4 to make it to 80
Answer/Step-by-step explanation:
Let x = 4 (you and 3 friends)
Ticket cost per head = $5.50
Drink cost per head = $2.50
Popcorn cost per head = $4.00
<em>Expression representing total amount of money spent = $5.50(x) + $2.50(x) + $4.00(x)</em>
<em />
Evaluate the expression by plugging in the value of x = 4
Total amount of money spent = $5.50(4) + $2.50(4) + $4.00(4)
= $22 + $10 + $16 = $48
<em>Total amount of money spent = $48</em>
