Answer: 2.66 × 10⁻¹³
<u>Step-by-step explanation:</u>
First, use the decay formula
where
- A is the final amount (amount left)
- A₀ is the initial amount (amount you started with)
- k is the rate of decay (you need to solve for this)
- t is the time
Given:
- A = 1/2(300) = 150
- A₀ = 300
- k = unknown
- t = 28.8

Next, input the k-value and the new t-value to solve for A.
- A = unknown
- A₀ = 300
- k = -0.0240676
- t = 1440

Answer:
Solved using the <u>Exterior angle theorem</u>.
2x-5+x-17 = 128
3x-22 = 128
3x = 150
x = 50
Answer:
$0.75
Step-by-step explanation:
Given
Normal price - $3.70
If Hamburger is on sale for 20% off the normal price
The amount that can be saved will be 20% of $3.70
Amount that can be saved = 20/100 * 3.70
Amount that can be saved = 1/5 * 3.70
Amount that can be saved = 3.7/5
Amount that can be saved = 0.75
Hence the Amount that can be saved on $3.70 is $0.75
The monthly amortization is P23,511.63
<h2>Compound interest</h2>
The formula for calculating the compound interest is expressed as:

whrere:
- P is the principal = P700,000
- r is the rate = 12% = 0.12
- t is the time = 4 years
- n = 12
Substitute the parameters

Calculate the monthly payment:
Monthly payment = 
Hence the monthly amortization is P23,511.63
