Hello there! Circumference is pi * diameter. Radius is ½ of the diameter. In order to find the diameter, all you have to do is divide the circumference by pi (3.14). 84.78/3.14 is 27. Now, divide that number by 2 to get 13.5. There. The radius of the Brazillian coin is 13.5 mm.
Answer:
C
Step-by-step explanation:
First we need to find W. You can do that by dividing 47.25 by 5.25.
47.25 / 5.25 = 9
So W = 9.
Now we do both equations to see which one is correct.
Equation A: 3/4 × 9 = 6 3/4, which is true.
Equation B: 9 - 10.24 = -1.24, which is also true.
Therefore, both equations give you the same solution, C.
X/31=55/100 31×55=1705 1705÷100= 17.05 so x=$17.05
Answer:
It would be $12.15.
Step-by-step explanation:
You would multiply 45% of 27.
45 * 27 = $12.15
From the given table, the points can be written as : (6,7.55) , (12,7.85), (18, 8.15) and (24, 8.45)
Slope
m =
m = 0.05
slope intercept form of line =
We plug m = 0.05, x = 6 and y = 7.55 and find c.
c= 7.25
