Answer: A
Step-by-step explanation:
Sams is greater than Wendy’s
To find the answer you have to find the area of the fountain using A= pi r^2.
=(3.14)(64)
=200.96
Then you have to find the area of the big circle.
=(3.14)(11^2)
=379.94
Then subtract them both (379.94-200.96) and you get the answer 178.98 which can be rounded to 179 aka A.
Answer:
This system have 9000 different numbers.
Step-by-step explanation:
We know that the internal telephone numbers in the phone system on a campus consists of 4 digits, with the 1st not equal to 0.
We have total 10 digits.
In the first place we have 9 possibilities, because from the conditions of the task in the first place there cannot be 0.
In second, third and fourth place we have 10 possibilities.
Therefore, we get

This system have 9000 different numbers.
Answer:

Step-by-step explanation:
We have to use the slope formula: m = slope
(x1, y1) = coordinates of the first point in the line
(x2, y2) = coordinates of the second point in the line
Here, we'll plug into our given points to give; 
Solving this, we get,
, but we're not done, as this fraction can be reduced.
Diving both sides of the fraction by 2, we get our final answer of
.
The second one. She did not correctly distribute 3 to (x-10) it’s supposed to be 3x-30 not 3x+30
