<u>Answer:</u> The final answer must have only one decimal place.
<u>Step-by-step explanation:</u>
Significant figures are defined as the figures present in a number that expresses the magnitude of a quantity to a specific degree of accuracy.
We are given:
An addition problem having values (34.530 g + 12.1 g + 1222.34 g)
<u>The rule that is applied for the addition and subtraction is:</u>
The least precise number present after the decimal point determines the number of significant figures in the answer.
For the given problem, the least precise number after the decimal is '1'
Evaluating the value: (34.530 g + 12.1 g + 1222.34 g) = 1268.97 ≈ 1269.0
Hence, the final answer must have only one decimal place.
Answer:
w = weight of Adrian's cat
c = weight of Lauren's cat
c = 3 + w/2
given: c=10
10 = 3 + w/2
Solve to get 'w': 20=6+w; w=14 pounds
Step-by-step explanation:
Answer: 90 textbooks
Step-by-step explanation:
everytime you multiply the number of students you multiply the books by the same number. to find how many times 72 was multiplied you divide it by 12.
72 ÷ 12 = 6
then multiply the original number of books (15) by 6.
15 * 6 = 90
so for every 72 students the school orders 90 textbooks
2.14 x 6 + 53.87 = y
12.84 + 53.87 = y
66.71 = y
Sooo the predicted height at the time of 6 weeks is 66.71 and then you’d put inches or centimeters or whatever unit after that. :) hope this helps!
