Step-by-step explanation:
An + c = d
an=d-c
a=(d-c)/n is your answer
Answer
a= 15
b= 2
So, 647÷3= 215 + 2/3

i just got it correct
Answer:
25.1cm
Step-by-step explanation:
since circumference =
d and d=2r
c=(2*4)
c=8
c=25.132741229
c=25.1cm
The possible orders in which Elliott can do these tasks is 24
<h3>
What is Permutation ?</h3>
Permutation is defined as the number of ways r number of objects can be arranged in total n number of objects.
P(n,r) = n! / (n-r)!
As Elliot have 4 tasks to do practices the piano (A), walks his dog(B), does his homework(C), and cleans his room(D)
4 Task can be done in 4! ways = 4 * 3 * 2 * 1 = 24 ways
ABCD ABDC
ACBD ACDB
ADBC ADCB
This is for when Elliot does piano first (A)and then walks his dog(B), does his homework(C), and cleans his room(D) .
Similarly for other 3 works , total 24 possible orders can be followed.
