60/100 is 3/5 so Anna colored 60% of the paper blue
Answer:
28 ft squared
Step-by-step explanation:
The 4 sides of a square are equal in length, so if the perimeter is 20ft that means each side would have to be 5ft, (20/4 = 5). If you increase the length by 2ft, one of the sides would now become 7ft (5+2 = 7). If you decrease the length of the other side by 1ft, the length would now be 4ft (5-1=4). Now to find the area, all you have to do is length * width. So you would do 7ft*4ft which is 28ft squared.
Answer: The first day the author reaches 100 days is on day 16.
To solve this problem, you could use a graphing calculator to graph the given equation. Then, determine when this line crosses 100. It crosses when x = 15.539. Therefore, we would have to round up to 16 so it is at least 100.
You could use the quadratic equation to solve: 100 = x^2 -12x + 45
Either you will get 16. If you use the quadratic formula, make sure to only use the positive answer.
Answer:
C. 
Step-by-step explanation:
Let 
, 
and 
. From statement we know that 
, which is equivalent to the following linear algebraic formula:
![B(x,y) -A(x,y) = \frac{1}{2}\cdot [C(x,y)-B(x,y)]](https://tex.z-dn.net/?f=B%28x%2Cy%29%20-A%28x%2Cy%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D%5Ccdot%20%5BC%28x%2Cy%29-B%28x%2Cy%29%5D)
(1)
(2)
Then, the coordinates of point B on AC are:
Which means that correct answer is C.
