A^2 + b^2 = c^2
4^2 + b^2 = 10^2
16 + b^2 = 100
b^2 = 100 - 16
b^2 = 84
b = SqrRt 84 = 9.2 <- Correct answer!
We have two equation with two unknowns. Therefore, we can solve the x and y easily. There are a number of methods to apply here but I will be using substitution method. We do as follows:
-2x + y = 1
y = 1 + 2x
4x + y = -1
4x + 1 + 2x = -1
6x = -1 -1
6x = -2
x = -1/3
y= 1 + 2(-1/3)
y = 1/3
Answer:
B. 29.7
Step-by-step explanation:
All you have to do is find the area of the half circle (r² × 3.14 × ½) and subtract that from the initial area of the rectangle ( 9×4 ) After doing that it gives you 29.7ft².
Answer: 12
Step-by-step explanation: because each pack is 50cents so multiply .50 by 24 so the answer is 12
