Answer:
No, her answer is unreasonable because 0.2 * 6 = 1.2
Step-by-step explanation:
Here in this question, we are trying to use an approximation to see if what was said to be the result of a calculation is reasonable as an answer.
Looking at her division, 2.76/6 = 0.19
To the nearest tenth , 0.19 is same as 0.2, now multiplying 0.2 by 6, what we have is 1.2 ( of which even 0.19 * 6 is expected to be less than this). we can see that this value is quite far from our expected answer of 2.76 which makes the answer an unreasonable one
Thus, the division 2.76/6 = 0.19 is not a reasonable answer

He would have walked 5 kilometers because 12 goes into 60 5 times
Vertical angles are always equal. The vertical angles are the ones opposite each other. Therefore x would equal 40.
"<span>9 1/4 ounces of fertilizer, 3/4 ounce of fertilizer for each plant."
Divide the total amt. of fert. by the amt. that goes to each plant:
9 1/4 oz
-----------------------
(3/4) oz per plant
Convert 9 1/4 to an improper fraction: 9 1/4 = 37/4.
Now divide 37/4 by 3/4, or divide 37 by 3. Result: 12 1/3 plants.
Ms. Marks can fertilize 12 plants and have 1/3 oz of fertilizer left over.</span>
