Answer: 130
Step-by-step explanation:
Let x be the original number of hip- hop CDs in the music store.
Given : A music store has sold 3/5 of their hip-hop CDs, but 10 were returned.
i.e. The number of hip- hop CDs in the store will be :
Original No. of CDs - CDs sold + CDs Returned
If the store has 62 Hip-Hop CDs now , then required euation will be :-
Subtract 10 from both sides , we get
Hence, the number of CDs they originally have = 130
Answer:

5 Parts Yellow with 3 Parts blue
5Yellow with 3 Blue
1Yellow would be with 3/5 Blue
Hence ,
2 Yellow = (3/5)*2 Blue =6/5 Cans of blue or 1.2Cans of blue.
Answer:
15.6
Step-by-step explanation:
First, multiply the midpoint of each class by its frequency, as follows:
Class midpoint frequency midpoint*frequency
0-9 4.5 24 4.5*24 = 108
10-19 14.5 20 14.5*20 = 290
20-29 24.5 32 24.5*32 = 784
Total 76 1182
The mean is computed as the division between the addition of the "midpoint*frequency" column by the addition of "frequency" column.
mean = 1182/76 ≈ 15.6
Answer:
3.75 L
Step-by-step explanation:
3 liters / 36 m^2 = x liters / 9 x 5 m^2
3 liters / 36 m^2 = x liters / 45 m^2
(45)(3) = (x)(36)
(135) = (x)(36)
x = (135)/(36)
x= 3.75 L
