An ice cream factory makes 29 quarts of ice cream in 5 hours. How many quarts could be made in 48 hours ? What was that rate per
Vadim26 [7]

We can easily get the quarts per hour rate by dividing the number of quarts by the number of hours:

\text{29 quarts in 5 hours} \implies \dfrac{29}{5} = 5.8 \text{ quarts in 1 hour}

Now that we have the quarts per hour rate, we can easily address the question: the factory could make

5.8\cdot 48 = 278.4

quarts in 48 hours, with a daily rate of

5.8\cdot 24 = 139.2

quarts per day

What is the missing number in the series?<br><br> 1, 16, 81, __, 625, 1296
Alinara [238K]

Answer:

256

Step-by-step explanation:

We are given the series

1, 16, 81, __, 625, 1296

The missing number in the sequence is the fourth term

From the above sequence, we know that

1, 4², 9² , __, 25² , 36²

Difference between first term = 4 - 1 = 3

9 - 4 = 5

x - 9 = 7

x = 9 + 7 = 16

Hence, the fourth term = 16²

= 256
