This process will just repeat forever so the answer is .8888888 repeating
So the answer is 1 and 1/9 or 1
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
Answer:
Step-by-step explanation:
This question is asking you "what angle gives you a cos of -square root 3/2"? The cosine by definition is the side adjacent to the angle over the hypotenuse. So set up the right triangle. We do not know which quadrant we are in since we are not told that, but if the cos is negative, then we are in either QII or QIII. In QII this is a 150 degree angle, and in QIII this is a 210 degree angle.
Yes, you are correct.
The two numbers you add to make twenty and have a difference of four are 12 and 8.
