52% is equivalent to 52/100. 52 and 100 can both be divided by 4 so the simplest form is 13/25.
{1,3,5}
ie, sub 1, 3 and 5 for x and see which one is true
20-2(1)=10
20-2=10
18=10
false
20-2(3)=10
20-6=10
14=10
false
20-2(5)=10
20-10=10
10=10
true
answer is 5
Kite, x = 3. since that really long line is an angle bisector bc it’s a kite, then the two x angles should be equal to each other
$40 minus the $2 for the water bottle = $38 minus the $20 he has remaining = $18 divided by the 4 water bottles he bought = 4.5 which is $4.50
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 " .
