Hello,
The formula for finding the circumference of a circle is
where r is the radius. SO we can plug 4 in for r in this formula because 4 is the radius:
. We are told to use 3.14 for
so we get
. Therefore, the circumference is 25.12 meters.
For the second work sheet:
5 2/8 - 4 1/4= 1 so NO
8 3/4 - 7 1/2= 1 1/4 so YES
2 1/8 - 1 7/8= 1/4 so NO
9 5/12 - 8 1/6= 1 1/4 so YES
Sorry if its not enough explanation, hope it helps!
Remark
When talking about straight lines, D is never true. Never.
C is possible, but in this case not true. Read on.
B. Might be true but in this case it is not. The lines (to be parallel) have to have the same number in front of the x. These two lines do when you divide through by 5. But the y intercept has to be different. That is not so in this case. So B is incorrect.
A is your answer. If you divide through by 5 on the second one, you get the first one. They are identical.
Answer:
9 - 7x - x²
Step-by-step explanation:
-4x+2x2-x²+5-3x = -4x-3x+2x2+5-x²
I arranged the like terms together so it is easier to do the calculations.
-4x-3x+2x2+5-x² = -7x+4+5-x²
Simplify.
-7x+4+5-x² = 9-7x-x²
Answer:
56
