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.

Answer:
always true
Step-by-step explanation:
Distribute the left side
2(x + 3) = 2x + 6
Simplify the right side
5x + 6 - 3x ← collect like terms
= 2x + 6
Thus
left side = right side , so always true
Answer:
These are the inequalities
A: ![W\geq -7](https://tex.z-dn.net/?f=W%5Cgeq%20-7)
B: ![W > -7](https://tex.z-dn.net/?f=W%20%3E%20-7)
C: ![W < -7](https://tex.z-dn.net/?f=W%20%3C%20-7)
D: ![W\leq -7](https://tex.z-dn.net/?f=W%5Cleq%20-7)
I assume the "different" one is referring to the wording of the expression. B, C, and D are all similarly worded so I believe A is the "different" one.
Basically, you take the amount of money earned, and divide it by the hours worked. So 734.15 divided by 37= 19.84189189189189 hope I helped
Answer:
1300
Step-by-step explanation:
the right answer is 1280.5
but becuase you estimate it doenst have to be exact, so 100x13 is the easiest to calculate in your head, so the estimate is 1300
