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.

The first paragraph is (it explains that the wood frog is a unique animal
Second (explains how the wood tree frog can survive in cold weather
That’s all I know hope it helps
This really depends on the fraction; if there are variables in the equation, if they are full numbers,etc. I'd really recommend looking up khan academy on YouTube and that will really help you out!
A. slope is rise/run. can count up 3 right 2. slope = 3/2
also by slope formula m = (y - y1)/(x - x1)
B. y-intercept is the y coordinate where the line crosses the y-axis.
See that it is at y = -4 on the graph?
To use the slope.. go backwards from the closest point (4,2) down 2 left 3 gets you to the next point (2,-1) then go down 2 left 3 again to get to y-intercept (0, -4)
C. y = (3/2)x - 4
How you get it is by putting in the values into the standard equation for a line; y = mx + b
m is slope and b is y-intercept.
