This is the concept of algebra, to calculate the proportion of wool in each item we proceed as follows;
Let the amount of wool used for hat be x
amount of wool in sweater will be 5x
the amount of wool used in scarf will be x-5
therefore the total amount of wool will be:
x+5x+(x-5)=550
x+5x+x-5=550
7x-5=550
7x=550+5
7x=555
hence;
x=555/7
x=79
the amount used in hat x=79g
amount used in sweater 5x=395g
amount used in scarf=79-5=74g
Answer:
781250
Step-by-step explanation:
We first need to find the common ratio
-10 /2 = -5
50 / -10 = -5
The common ratio is -5
an = a (r) ^ (n-1)
a9 = 2 ( -5) ^(9-1)
= 2 (-5)^8
=781250
