Answer:
C. 88 in.
Step-by-step explanation:
This is because the equation for the circumference of a circle is pi times diameter. To get the diameter, multiply the radius by 2. Then do 28*3.14 to get the circumference of the circle then round your answer to get the nearest whole number which is 88 in.
Answer:
None are equivalent
Step-by-step explanation:
Answer:
124 miles.
Step-by-step explanation:
From the question given above, the following data were obtained:
1 in = 20 miles
6 1/5 in =?
Next, we shall express 6 1/5 in decimal for easy calculation . This can be obtained as follow:
6 1/5 = 31 / 5
6 1/5 = 6.2 in
Finally, we shall convert 6.2 in to miles. This can be obtained as follow:
1 in = 20 miles
Therefore,
6.2 in = 6.2 in × 20 miles / 1 in
6.2 in = 124 miles
Thus, 6 1/5 in is equivalent to 124 miles.
Therefore, there are 124 miles between the two towns.
Answer:
D. Minimum at (3, 7)
Step-by-step explanation:
We can add and subtract the square of half the x-coefficient:
y = x^2 -6x +(-6/2)^2 +16 -(-6/2)^2
y = (x -3)^2 +7 . . . . . simplify to vertex form
Comparing this to the vertex for for vertex (h, k) ...
y = (x -h)^2 +k
We find the vertex to be ...
(3, 7) . . . . vertex
The coefficient of x^2 is positive (+1), so the parabola opens upward and the vertex is a minimum.
