10 x 8 = 80ft for the rectangle
To work out the area of the semi circle you do pi (3.14) x the radius squared, the radius is half the diameter.
3.14 x 4 squared
3.14 x16 = 50.24ftsqaured for the whole circle so you divide it by 2 which is 25.12ft squared.
And then finally you add 25.12 and 80 so your answer is 105.12 ft squared
The answer would be -9
I hope this helps.
Answer:
8
Step-by-step explanation:
So first do 104+76+104=284
Now form the equation 10x-4+284=360
It is 360 because this is a quadrilateral.
Now combine like terms.
10x+280=360
10x=80
x=8
Check 80-4=76
The other angle is 76 so you know your answer is correct
Well without seeing the tables it is hard to answer. However, I will offer some help. f(x) is actually y. A function of x=y. So, now you have y=2x-1. Plug the x and y values in from the tables and make sure the equations are true with the given values (equal on both sides). For example, (2,3).. 3=2(2)-1...... 3=3. Hope this helps.
3 5/10 = 35/10
Therefore, (35/10)/2
= 35/20
