Answer:
y = 8(.88)^x
y = 4.221855 for the fifth reduction
Step-by-step explanation:
We can use the formula
y =ab^x
where a =the initial value
b= 1 -percent decrease
a = 8 inches
b = 1-12%
= 1-.12
= .88
y = 8 (.88)^x
The fifth reduction is
y = 8 (.88) ^5
y = 4.221855
Answer:
20 stacks of 5 pennies weight 0.33 pounds
Step-by-step explanation:
<u>First, we need to calculate the weight in kilograms of 20 stacks of 5 pennies:</u>
20 stacks= 0.0075*20
20 stacks= 0.15 kg
<u>Now, we can determine the weight in pounds:</u>
1kg = 2.2 pounds
0.15kg = ?
Weight in pounds= (0.15*2.2)/1
Weight in pounds= 0.33 pounds
20 stacks of 5 pennies weight 0.33 pounds
4.5/9. It is technically an improper fraction but it still counts.
Answer:
V = 1/3 * b * h...divide both sides by 1/3h
V / (1/3h) = b
3V/h = b
