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:
y= 11.4
Step-by-step explanation:
In an equilateral triangle, each angle is the same
180/3=60
So each angle equals 60
5y+3 =60
Subtract 3 from each side
5y +3-3 = 60-3
5y = 57
Divide by 5
5y/5 = 57/5
y = 11.4
The answer to that question is 11
Hey there!
Let's first define our goal. Our goal here is to be able to isolate the variable, n, and solve for it by moving everything to the other side. We see that we have two sides of the equation, and by using the property of equality which states that whatever you do to one side you do to the other and the expression remains equal, we can solve this equation.
It looks like the only thing we have on the left side with n is that 6 1/2. In order to get rid of it, we must subtract it from both sides, because the property of equality states you must do the inverse operation.
We have:
n = 12 - 6 1/2
n = 5 1/2
Hope this helps!
