A chef uses 3 3/4 pounds of semolina flour and 1 5/8 pound whole wheat flour for each batch of pasta she makes.one week she uses
Maurinko [17]
It is to be noted that for this item, we more concern of the pounds of flour. The number of batches is calculated by dividing the total mass of flour used by the amount per batch. That is,
                                              n = 86 lbs / (1 + 5/8 lbs/batch)
                                              n = 52.92 batch
Thus, the chef makes approximately 53 batches of pasta.

Make a conjecture about the next item in the sequence 1, -4, 9, -16
Snezhnost [94]
To get -4 from 1, we must either subtract 5 from 1 or mult. 1 by -4.  Unfortunately subtracting 5 from -4 does not result in 9, and mult -4 by -4 does not result in -16.  So neither "works"  in predicting the next term.

Can you think of any other experiments to do that would help you discover the pattern 1, -4, 9, -16?

Round 6.5008 to the nearest .001
kicyunya [14]

Answer: 6.501

Step-by-step explanation:

so we are not rounding to the nearest TENTH... we are not rounding to the nearest HUNDRETH... we are rounding to the nearest THOUSANDTH.

so it would be whichever 8 is closest to: 10 or 0? 8 is closest to 10.

so 6.5008 becomes 6.501
