11 shelves
Step-by-step explanation:
96/9= 10.6666
since you have more books you cannot round down you have to round up. so you need 11 shelves
Answer:
1/p^2
Step-by-step explanation:
To get rid of a negative exponent, make it under a 1/
If a divides c,
then 'a' is a factor of 'c'.
Also,
If 'b' divides c,
then 'b' is also a factor of 'c'
therefore,
'a' and 'b' are factors of 'c'
Hence, a and b divides 'c'
so, c = a*b
and ab will also divide c.
Hence, proved.
Answer:
28.26ft^2
Step-by-step explanation:
The formula for area of circle is:
A=3,14*r^2, where r =3 and 3,14 is pie number, so we have
A=3.14*9=28,26
Answer:
$213.41
Step-by-step explanation:
To do this question, you have to use the formula for compound interest:
A=P(1+r/n)^nt
The A is the final amount of money you make which is $237.60. P is your initial amount that you are trying to solve for. R is the rate of interest. However, for r you have to convert the percent into a decimal so divide 1.2 by 100, which would be 0.012. N is the number of times it is compounded annually which is once. And finally, t is the number of years taken, which is 9. If you substitute the numbers into the equation it should look like this:
237.60=P(1+0.012/1)^1*9
If you solve for P, you should get $213.41.
Hope this helps :)
