Answer:
D. The rate of change must be 20 pounds per minute.
Step-by-step explanation:
At time 0, the amount of sand is 200 lb. Time zero is when it starts, so it is also called the initial time. The initial value is 200 lb, so choices A and B are wrong.
Now look at the difference from time 0 minutes to time 1 minute. The amount of sand went from 200 lb to 220 lb. The amount of sand placed in 1 minute is 20 lb, so the rate of change is 20 lb per minute. That makes choice C wrong and choice D correct.
Answer: D. The rate of change must be 20 pounds per minute.
n, n + 2, n + 4 - three consecutive even integers
3n = 2(n + 4) + 4 |use distributive property
3n = (2)(n) + (2)(4) + 4
3n = 2n + 8 + 4
3n = 2n + 12 |subtract 2n from both sides
n = 12
n + 2 = 12 + 2 = 14
n + 4 = 12 + 4 = 16
Answer: 12, 14, 16.

Hello!
<h2>Answer:</h2>
The accountant's yearly salary is $57,668.00.
<h2>___________________________________</h2><h2>Explanation:</h2>
We know that she earns $1,109 per week.
There are about 52 weeks in a year.
$1,109 × 52 = 57,668
6*40 for how much u make a week then divide 16 by 2 for every other week. Then multiply your sum for 6*40 by 16/2
So you would make $1,920
