Answer:
Explanation:
The number of emails is multiplied by <em>4</em> every <em>9.1 weeks.</em>
Thus, since <em>Tobias initially sent the chain letter to 37 friends</em>, the number of letters will grow as per this geometric series:
Start: 37 letters
- In 2 × 9.1 weeks: 37 × (4)²
- In 3 × 9.1 weeks: 37 × (4)³
As you see, the exponent is the number of weeks divided by 9.1
Thus, if your variable is the number of weeks, t, then the exponent is t/9.1
And the exponential function, P(t) will be:

Gram and milligram are in the metric system and are for weight. Pound is the United States system and kiloliter measures liquids
Answer:
O weight in kilograms = 25 x 3.5 ÷ 2.2
Step-by-step explanation:
As a butcher, you sell beef in 3.5-pound packages. You anticipate needing 25 packages for the next two days.
Therefore, the total number of pounds for the 25 packages =
3.5 pound packages × 25
= 87.5 pounds
We are told that : The wholesaler from whom you purchase large pieces of meat measures the weight of the beef in kilograms.
Note that:
2.2 pounds = 1 kg
Hence:
87.5 pounds =
= 87.5÷ 2.2
= 39.772727273 kg
He needs to buy 39.772727273kg from the wholesaler
The equation can you use to determine the weight of the beef, in kilograms, that you need to purchase from the wholesaler is:
O weight in kilograms = (25 x 3.5) ÷ 2.2
