Answer:
7/2
Step-by-step explanation:
1/8 + 1/4, you must change the denominator so that they are the same.
So that would mean 1/8+ 1/8, but since the denominator for the second one was 1/4 we must multiply the top by 2. So it becomes 1/8+2/8. You then change the denominator for the rest of them like this and it becomes 1/8+2/8+3/8+4/8+6/8+7/8 which simplified equals 7/2.
Answer:
The absolute value is always positive no matter if there's a negative.
Step-by-step explanation:
Okay, so the y-intercept is the "b" in this case and the m is your slope so, therefore, you have y=- 1/2x-5
Answer: 44g
Step-by-step explanation:
Half life refers to the length of time it takes for half of the atoms of the element in question to decay.
The half life here is 1 minute which means that in a minute, the amount of protactinium left would be:
= 352 / 2
= 176g
After the second minute:
= 176 / 2
= 88g
After the third minute:
= 88 / 2
= 44g
