Step-by-step explanation:
The equation of circle in standard form is 
<h3><u>Solution:</u></h3>
Given that circle having center point (3,7) and the radius r = 4
To find: equation of circle in standard form
<em><u>The equation of circle is given as:</u></em>

Where center (h,k) and radius r units
Given that center point (h , k) = (3, 7) and radius r = 4 units
Substituting the values in above equation of circle,

Thus the equation of circle in standard form is 
A.) 135 miles in 3 hours = 45 miles per hr
B.) 22 miles in 1 hour= 22 miles per hr
C.) 7.5 miles in 1/4 hour = 30 miles per hr
D.) 100/3 in 2/3 hour = About 49.9 mph
E.) 97.5 in 1.5 hours = 65 miles per hr
Answer:

Step-by-step explanation:
Battery is down currently = 2/5
Battery drains at the rate of 1/9 every hour.
Remaining battery life of Vera = 1 -2/5 = 3/5
Let y we the number of hours battery will last.
So, 1/9 y = 3/5
y = 27/5
y = 5 + 2/5 hours
y = 5 hrs and 24 mins
So battery will last another 5 hrs and 24 mins.
hope this helps:)
