i dont knpw haha. sorry
Step-by-step explanation:
the answer is 58
because to find the perimeter all you do is add all the sides together which is 12+15+8+9+14=58
i hope this helps you
For 25, I would begin with working out the difference in price.
$450 - $360 = $90
Then, $450 is 100% of the cost, therefore we want to know how much it has decreased.
I would work out 1% of $450. [$450 / 100 = $4.50]
Now if we divide $90 (the change in cost) by $4.50, we can tell what percent of a decrease we have.
90 / 4.5 = 20
Therefore we have a 20% decrease.
Answer:
60,480 is the correct answer.
Step-by-step explanation:
First of all, let us have a look at the <em>formula of factorial of a number 'n'</em>:
i.e. multiply n with (n-1) then by (n-2) upto 1.
<em>Keep on subtracting 1 from the number and keep on multiplying until we reach to 1.</em>
<em></em>
So, can be written as:
Similarly can be written as:
Re-writing :
Now, the expression to be evaluated:
