2 answers:
Answer:
200,-1000,5000
Step-by-step explanation:
First we need to find the common ratio
Take the second term and divide by the first
-10/2 = -5
To find the 5th term take the 4th term and multiply by the common ratio
-40*-5 = 200
To find the 6th term take the 5th term and multiply by the common ratio
200 *-5 = -1000
To find the 7th term take the 6th term and multiply by the common ratio
-1000*-5 = 5000

I believe it would be 41.25, just multiply the two numbers. Hope this helps
20+8(q-11)=-12
20+8q-8•11=-12
20+8q-88=-12
-68+8q=-12 add 68
+68 +68
8q=-12+68
8q=56 divide by 8
/8 /8
q=56/8
q=7 solved for q
Annual ROI is approximately 83.3%
Find annual profit: $75,000/6 = $12,500
ROI = Annual Profit/ initial investment
ROI = $12,500/$15,000 or 83.3%
Remember that "of" means to multiply.
(1/12) of 180 coins are dimes. The number of dimes will be
(1/12)*180 = 180/12 = 15
