Use the geometric sequence formula to solve for rate:
an=a1r^(n-1)
6.75=4.5r^(2-1)
6.75=4.5r
6.75/4.5=r
r= 1.5
and if you want to make sure just multiply each number by 1.5 and see if it gets you the next number
4.5 4.5×1.5=6.75 (holds true)
6.75 6.75×1.5=10.125 (holds true)
10.125 10.125×1.5=15.1875 (holds true)
15.1875
1.5 is the multiplicatice rate hope that helps :)
If im looking at it correct theres no solution
Answer:
24 cent
Step-by-step explanation:
If 13 inches of wire cost 39 cent.
We have to calculate how much 1 inch of wire would cost first, before determining the cost of 8 inches of wire.
If 13 inches of wire costs 39cents, Then 1 inch of wire would cost 3 cent.
That is 39/13, which gives 3.
If 1 inch of wire cost 3 cents. Two inches of wire would cost 6 cents we 3 inches of wire costs 9 cents.
To get the cost of 8 inches of wire, we therefore multiply 8 by 3, which gives 24.
8 inches of wire costs 24 cents.
