Answer: -129
Step-by-step explanation:
Given the sequence {-3, 6, -12, 24, ... }, we can see that the first term (a) is -3 and the ratio (r) is .
Input those values into the Sum formula:
What is the exponential equation for this problem?
What is the decay FACTOR?
What is the decay RATE?
144.64 is the number whose 56% is 81.
To find what number 81 is 56% of, we can set up the equation:
81 = 0.56x
To solve for x, we divide both sides of the equation by 0.56:
81 / 0.56 = x
x ≈ 144.643
Therefore, 81 is approximately 56 percent of 144.643.

Let p = number of pennies we need to find.
(3/10)/(4/5) = p/440
Solve for p to find your answer.
Answer:
880
Step-by-step explanation:
Multiply the numerator and the denominator of 4/5 by 2 so it can be added. Rachel's bank would now be 8/10 full. If 440 pennies made it half full (8/10-3/10= 5/10, which equals 1/2) then 880 pennies (440 times 2) would fill it up completely. Hope this helps!
