You find area by multiplying base and height.
The formula is A=bh
so 100=25h
25 times 4 is 100
100=25*4
4cm is your answer
Answer:
The answer is B :)
Step-by-step explanation:
Basically for a you subtract 4.5 from 4.1 and get -0.4 and for b you subtract 7.05 from 7.2 and get 0.15. Overall the answer is B, have a nice day.
The answer is: " <span>1.045 * 10¹⁰ " .</span>

Explanation:
______________________________________
"5.5 million = 5,500,000 = 5.5 * 10 ⁶ " ;
______________________________________
"1.9 thousand = 1,900 = 1.9 * 10³ " ;
______________________________________
So; "<span>5.5 million * 1.9 thousand" ;
_________________________________________
= (</span>5.5 * 10 ⁶) * (1.9 * 10³) = 5.5 * 10⁶ * 1.9 * 10³ ;
= 5.5 * 1.9 * 10⁶ * 10³ ;
___________________________________________
Note the following properties of exponents:
____________________________________________
xᵃ * xᵇ = x⁽ᵃ⁺ᵇ⁾ ;
____________________________________________
As such, " 10⁶ * 10³ = 10⁽ ⁶ ⁺ ³⁾ = 10⁹ " ;
_____________________________________
So; rewrite:
______________________________________
5.5 * 1.9 * 10⁶ * 10³ ;
_______________________________________
= 5.5 * 1.9 * 10⁹ ;
__________________________________
5.5 * 1.9 = 10.45 ;
__________________________________
Rewrite as: " 10.45 * 10⁹ " ;
In scientific notation, we need to rewrite as an single digit integer, followed by a decimal and other values (if applicable); following by * 10 raised to the appropriately adjusted exponential power.

As such, we write the value as:
________________________________________________
" 1.045 * 10¹⁰ " .
