Answer:
yes, it is arithmetic as the common difference is -8
To calculate this you need to multiply 225 by how many months,
6 * 12 = 72,
And so 225 * 72 = $16,200,
To find interest, minus the amount paid by the amount loaned:
16,200 - 15,000 = 1200, so the interest was $1200.
Hope this helps.
Answer:
34,860
Step-by-step explanation:
In a sample of 32 residence, 24 take Vitamin C. From here we can get the proportion of residents who take Vitamin C, which is 24/32 = 3/4 = 0.75
0.75 in percentage is 75%. This means 75% of the residents in sample take Vitamin C.
We can expect the same percentage of people in entire population to take Vitamin C.
Total population of city = 46480
Expected number of residents who take vitamin C in the city = 75% of 46480
= 0.75 x 46480
= 34860
This means, 34860 is an estimate of number of city residents who take Vitamin C supplement daily.
1) 2m - 16 = 2m + 4
2m - 2m = 4 + 16
0 = 20 (no solution)
2) -4(r + 2) = 4(2 - 2r)
-(r + 2) = 2 - 2r
-r - 2 = 2 - 2r
-r + 2r = 2 + 2
r = 4
3) 12(5 + 2y) = 4y - (6 - 9y)
60 + 24y = 4y - 6 + 9y
60 + 24y = 13y - 6
24y - 13y = -6 - 60
11y = -66
y = -6
