Answer:
Definitions of alpha, beta and gamma radiation, decay equations and half-life definition and calculations. Fission and fusion definitions and an example.
Answer:
1) 18^2 = 324
324 x 3.14 = 1,017.36 in2
2) half of 25 is:
12.5
12.5^2 = 156.25
156.25 x 3.14 = 490.625 m2
Answer:
4 years and 2 months
Step-by-step explanation:
<u>Simple interest formula</u>
A = P(1 + rt)
where:
- A = final amount
- P = principal amount
- r = interest rate (in decimal form)
- t = time (in years)
Given:
- A = $500 × 2 = $1,000
- P = $500
- r = 24% = 0.24
Substitute the given values into the formula and solve for t:







Therefore, it takes 4 years and 2 months for the initial investment of $500 to double at a simple interested rate of 24%.
Answer:
there is no equivalent ratio

Answer:
The angle x is 32 degrees.
Step-by-step explanation:
As the angles make supplementary angle then
148+x=180
x=180-148
=32 degrees
Hence Prooved!
