Answer:
60 lb. 17 oz
Step-by-step explanation:
Just add each same values together.
<u>2x
</u> 2
The 2's will reduce down to 1's
<u>1x</u>
1
<em><u>x</u></em>
Answer:
<em>The coordinate of the midpoint is 1/2</em>
Step-by-step explanation:
<u>Midpoint</u>
The midpoint of a segment defined in a one-dimension system is

Where x1 and x2 are the coordinates of the points.
The given segment has endpoints x1=-7 and x2=8, thus:


The coordinate of the midpoint is 1/2
Answer: d - the amount of space occupied by an object (its capacity)
Explanation:
[a] The total distance around a figure is the perimeter, this does not answer our question.
[b] The average of the sum of all items is the mean, this does not answer our question.
[c] The exposed surface of a solid shape is the object's surface area, this does not answer our question
[d] The amount of space occupied by an object is the object's volume, so this <em>does</em> answer our question.
Answer:

Step-by-step explanation:
We will use the standard formula for half-life:

Where A₀ is the initial amount, a is the half-life, d is the time for one half-life, and t is the number of days.
So, we will substitute 1/2 for a and 24.3 for d. This yields:

We have a 3 gram sample. Therefore, our initial amount A₀ is 3:

And we want to find the remaining sample after 10 days. So, t=10. Substitute:

Use a calculator. So:

Therefore, for a 3 gram sample of Phosphorous-32 with a half-life of 24.3 days, after 10 days, there will be approximately 2.255 grams remaining.
