The arithmetic sequence has a pattern of +4. From 17 you add 4, resulting to 21 and you continue.
Hope this helps !
Ratio:
Red : Total
2 : 5
(x2) (x2)
4 : 10
Green : Total
3 : 10
Total of red and green marbles = 4 + 3 = 7
Blue marbles = 10 - 7 = 3
10 parts = 40 marbles
1 part = 40 ÷ 10 = 4
3 parts = 4 x 3 = 12
Answer: There are 12 blue marbles.
Step-by-step explanation:
(-24)+19
= 19 - 24
= -5 (Ans)
Volume = L * W * D 6,510
= 40 * W * 10.5
W = 6,510/(40 * 10.5)
= 15.5 ft
hope this helps
