Answer:
1.23 repeating
Step-by-step explanation:
divide 37 and 30
We know that
We can write an Arithmetic Sequence as a rule:
<span>an = a1 + d(n−1)</span>
where
<span>a1 = the first term
<span>d =the "common difference" between terms
in this problem
a1=15 a2=7 a3=-1 a4=-9 ..... an=-225
d=a2-a1
d=7-15-----> d=-8
</span></span>an = a1 + d(n−1)
for
an=-225
d=-8
a1=15
find n
-225=15+(-8)*(n-1)--> (n-1)=[-225-15]/-8----> n-1=30---> n=30+1---> n=31
the answer is31
It has line symmetry and rotational symmetry, so A is the answer, hope this helps
Answer:
6 bracelets
Step-by-step explanation:
If she can make 3 in 15, just multiply by 2 to get 30 minutes. Therefore she can make 6 bracelets in 30 minutes.
