Answer:
5040
Step-by-step explanation:
1 * 2 * 3 * 4 * 5 * 6 * 7 = 5040
Answer:
140 in²
Answer as a decimal rounded to the nearest hundredth = 140.00 in²
Step-by-step explanation:
Area of a triangle = 1/2 × base × height
Given:
- base = 20 in
- height = 14 in
Substituting the given values into the formula:
⇒ Area = 1/2 × 20 × 14
= 140 in²
Answer as a decimal rounded to the nearest hundredth = 140.00 in²
A = pi x r^2
A = pi x 8^2
A = pi x 64
A = 201.061..
A = 201cm^2 (3sf)
Ok so
for a thing that is P amount at first, with a half life of k days
after t days, the amount left is A
the equation is
given
13% of P remained=A
t=400
replace A with 0.13P and t with 400
0.13P=
divide both sides by P
take the ln of both sides
multiply both sides by k
divide oth sides by ln0.13
k=
evaluate
k=135.897 days
the half life is 135.897 days
