Answer:
Just count and find the area of the units shown below,
6 x 2 = 12, 12 divided by 2 = 6
6 x 2(two of the triangles) = 12
7 x 3 = 21
21 x 2 = 42
7 x 6 = 42
Add all given areas:
12 + 42 + 42 = 96 is your answer
Answer:
(21, 5)
Step-by-step explanation:
y = -x
y = -(-7)
y = 7
The point is reflected, so it is equidistant on both sides of the reflection line. It takes 14 units to get to the reflection line, -7 + 14 = 7 (the reflection line).
So, another 14 on the other side would be 14 + 7 = 21

Answer:
12.2
Step-by-step explanation:
A^2 + B^2 = C^2
(7)^2 + (10)^2 = (C)^2
49 + 100 = C^2
149 = C^2
sqr(149) = C
12.2 = C
Step-by-step explanation:
a.
Let's give the starting amount of water as s. Every minute, 2 inches of water are lost, meaning that given the starting amount, s, we subtract 2 inches from s every minute, so s - 2 every minute = height of water left, so s - 2t (t representing minutes) = h
To figure out s, we simply plug our known value -- 9 minutes in and 11 inches left. s - 2(9) = 11, s-18=11, s= 29
29 - 2t = h
b. We know that we cannot have negative minutes, so the minimum amount of time that makes sense is 0. To figure out the maximum, we stop counting how much time has occurred when there is no water left, so we have to figure out when h = 0
29-2t = h = 0
t=14.5
Therefore, anything between 0 and 14.5 minutes makes sense
c. Anything between 0 and 29 makes sense because the height of water cannot be negative and we cannot get higher than the starting amount
