The decay factor here is 0.85, and it means the car’s value changes by 85% every year, or goes down by 15% every year.
The formula for exponential decay is y = a(1 - b)^x
y is the final amount.
a is the initial amount, which is $30,000 in this case.
(1 - b) is the decay factor, or the number the original value gets multiplied by each year, which is 0.85 here.
b is the percent decrease in decimal form. In this case, we can find it using the formula (1 - b) = 0.85. We soon find that b = 0.15, or 15%.
x is the number of years.
8+(16)/4 (divide 16 and 4 first, PEMDAS)
8+4 (add these two together)
12
If you would like to know how much does a 93-pound person weigh on the Moon, you can calculate this using the following steps:
120 pounds on the Earth ... 20 pounds on the Moon
93 pounds on the Earth ... x pounds on the Moon = ?
120 * x = 20 * 93 /120
x = 20 * 93 / 120
x = 15.5 pounds on the Moon
The correct result would be 15.5 pounds on the Moon.
Answer:
1.9 years
Step-by-step explanation:
There are 365 days in a year
694.44 / 365 = 1.9
Hope this helps!
Using the probability (conditional) formula, where P is equals to the number of favorable outcomes over the total number of outcomes. Calculating using five and the thirty percent, 1.5 is the answer. But that cannot be the answer.
So we look for the probability using this formula derived from the original, (total outcomes) x (percentage) = (favorable outcomes), 5x=2. That gives us the answer of 0.4 or 40%.
