Answer:

Step-by-step explanation

Kittens weigh about 100 grams when born and gain 7 to 15 grams per day. if a kitten weighed 100 grams at birth and gained 8 grams per day, in how many days will the kitten trie its weight.If you answer please, if possible tell me how u solved it.

Answers

For it to triple its weight, it would need to be 300 grams. It already starts off with 100 grams, and so it needs to gain at least 200 grams in x days. If it gains 8 grams a day, we can calculate the number of days it takes to gain 200 grams by dividing. 200/8 = 25. So, it would take the kitten 25 days after its birth to triple its weight.

Answer:300

Step-by-step explanation:

Find the product of 21 and (6.3 • 10-4).

Answers

Answer:

1,239

Step-by-step explanation:

This problem can be rewritten as 21 • (6.3 • 10 - 4)

Following the order of operations (PEMDAS) we first have to solve what's in the parentheses.

The next letter is M for multiplication so we have to do 6.3 times 10 which makes 63. That makes 63 - 4 which is 59.

Lastly, since we finished the parentheses, we then do 21 • 59, which solves to be 1,239.
