X^2+y^2-6x+2y-36=0. Use the equation of the circle (x-h)^2+(y-k)^2=radius^2, center (h,k) is (3,-2)
Answer: 36th customer.
Step-by-step explanation: 36 is divisible by both 9 and 12, and is the least common multiple.
Using proportions, the approximate length of time, in years, for the watch to lose exactly 24 hours is:
(d) 240.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
24 hours have 24 x 3600 = 86400 seconds, hence the <em>rule of three</em> is given by:
One second - 1/365 year
86400 seconds - x years
Applying cross multiplication:
x = 86400/365
x = 240.
Hence option D is correct.

First you need to find a expression that gives you any number of sticks for a number(n) of houses. Start by looking at one house, then two and the third. You will see that the number of sticks is found by 4n + 1, and n is the number of houses.
So to find how many houses there will be if 61 sticks are used, you set 61 equal to the expression 4n + 1 and you should get n = 15
