Answer:answer is b
Step-by-step explanation: Just makes since
Answer:
Step-by-step explanation:
2(l+b)=16
Also it is given that l=2b+2
2(2b+2+b)=16
3b+2=8
b=2metre
l=2(2)+2
l=6metre
The given formula is f(x) = 20(1.2)^x
The formula is the starting amount multiplied by 1 + the percentage raised to the number of weeks.
A) the percent increase is 20% ( 1.2 in the formula is 1 +20% as a decimal)
B) the original amount is $20
C) for 2 weeks, replace x with 2 and solve:
20(1.2)^2
20(1.44) = $28.80
After 2 weeks the coupon is $28.80
D) To solve for the number of weeks (x) set the equation equal to $100:
100 = 20(1.2)^x
Divide both sides by 20:
5 = 1.2^x
Take the natural logarithm of both sides:
ln(5) = ln(1.2^x)
Use the logarithm rule to remove the exponent:
ln(5) = x ln(1.2)
Divide both sides by ln(1.2)
x = ln(5) / ln(1.2)
Divide:
X = 8.83
At 8.83 weeks the coupon would be $100, so after 9 weeks the coupon would be greater than $100
The answer is 9 weeks.
Answer:

Step-by-step explanation:
- We first compute the ratio of this geometric sequence.

- We simplify the fractions:

- We deduce that it is the common ratio because it is the same between each pair.

- We use the first term and the common ratio to describe the equation:

Answer:
2 1/3 cups
Step-by-step explanation:
The total number of cups of mixed nuts purchased is ...
(8 bags)·(3 1/2 cups/bag) = 8·3.5 cups = 28 cups
When those are shared 12 ways, each share is ...
(28 cups)/(12 shares) = (28/12) cups/share = 2 1/3 cups/share
Each share is 2 1/3 cups.
