Answer: 98.1
Step-by-step explanation:
Given: mass= 970 gm
Time = 14 min
rate of decay= 15.1% per minute.
Now, computing to get amount of element remaining after 14 minutes.
Formula; Element remaining=
Element remaining=
⇒ Element remaining=
⇒ Element remaining= ≅ 98.1 (nearest 10th of a gram)
∴ 98.1 element is still remaining after 14 minutes.
So what we do is we first get the x on the right side: 7x-x = 6x.
Now we get the 5 to the left side: 71-5= 66.
Now our equation is 66=6x.
We divide 66 by 6 which makes x=11
Answer:
+ 1 or - 1
Step-by-step explanation:
= ± 1
Since 1 × 1 = 1 and - 1 × - 1 = 1
Assuming those are all the lengths of the shape you need to take the sum of all the lengths to get the perimeter.
2+5+5+2=14m is the perimeter
