Answer: 222 parts per hour
Step-by-step explanation: To find how many parts a manufacturer Can produce in 1 hour if it can produce 1,554 parts in 7 hours, then look for the unit rate. (1,554/7) To do this, simply divide 1,554 by 7, which gives you a final answer or result of 222. Hence, a manufacturer can produce 222 parts in 1 hour.

Answer:
the value of y is D.100
Step-by-step explanation:
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
