Answer:
Angelica's bouquet has 7/12 pink roses.
Step-by-step explanation:
A dozen is defined to be a set of 12 in number or group pf anything. Here, in this case we have roses so a dozen of roses means '12 roses'.
5 of the roses in the bouquet are white roses, so the fraction of white roses will be 5 divided by the total number of roses i.e. 12:
White roses =
Rest of the roses are pink, so we can simply subtract 5 from 12 to get the number of roses which will be 12 - 5 = 7
Or
we can subtract the fraction of white roses from 1 to get the fraction of pink roses in the bouquet:
Pink roses = =

Answer:
The required recursive formula is
Step-by-step explanation:
Mohamed decided to track the number of leaves on the tree in his backyard each year.
The first year there were 500 leaves
Each year thereafter the number of leaves was 40% more than the year before so that means
For the third year the number of leaves increase 40% than the year before so that means
Similarly for fourth year,
So we can clearly see the pattern here
Let f(n) be the number of leaves on the tree in Mohameds back yard in the nth year since he started tracking it then general recursive formula is
This is the required recursive formula to find the number of leaves for the nth year.
Bonus:
Lets find out the number of leaves in the 10th year,
So there will be 10330 leaves in the 10th year.
