Answer:
D.
Step-by-step explanation:
The wildfire begins at a size of 8 square feet
It means that initial area =8
It then doubles its width every x hours,
and doubles its length every y hours
so, we can set up equation
now, we can simplify it
we are given
After a period of time, the wildfire covers 14,000 square feet
so, we can set A(x,y)=14000
we get
You worded this weird but wouldn't it be eight?
Multiply the hours buy her hourly pay:
6 × 40 = 240
6 × 6.5 = 39
6 × 8 = 48
Add them together:
240 + 39 + 48 = 327
ANSWER: Mary Stevens made $327.
I really hope this helped you! c:
The sum of all the even integers between 99 and 301 is 20200
To find the sum of even integers between 99 and 301, we will use the arithmetic progressions(AP). The even numbers can be considered as an AP with common difference 2.
In this case, the first even integer will be 100 and the last even integer will be 300.
nth term of the AP = first term + (n-1) x common difference
⇒ 300 = 100 + (n-1) x 2
Therefore, n = (200 + 2 )/2 = 101
That is, there are 101 even integers between 99 and 301.
Sum of the 'n' terms in an AP = n/2 ( first term + last term)
= 101/2 (300+100)
= 20200
Thus sum of all the even integers between 99 and 301 = 20200

The answer is 12. All you had to do was divide.
So, 30 divided by 2.5 equals 12.
I hope this helps!
