3.25 * 7.8 = 25.35
10^3 * 10^6 = 10^(3+6) = 10^9
so we have 25.35 * 10^9 but in scientific notation the first number mus be <10
so the answer is 2.535 * 10^10
Answer:
The answer to your question is Apothem = 9 cm
Step-by-step explanation:
Data
Area = 216 cm²
Perimeter = 48 cm
Formula
Area = Perimeter x apothem / 2
Perimeter = length of the side x number of sides
Process
Substitute the values in the area formula and simplify it.
1.- Substitution
216 = 48a/2
-Solve for a
216 x 2 = 48a
432 = 48a
a = 432 / 48
-Result
a = 9 cm
Answer:
<h2>600 km</h2><h2 />
Step-by-step explanation:
<u>400 km</u> = <u> x </u>
6 min 9 min
cross multiply:
6x = 400 ( 9)
x = 3600 / 6
x = 600 km
Alright, so we do 100*(0.9)^5 due to that you do 0.9 5 times. This equals to approximately 59
