The answer as a mixed number is 
Step-by-step explanation:
Given:
5 1/4 ÷ 1/3.
Now, to solve as a mixed number in simplest form.

<em>Now, changing the mixed fraction into improper:</em>

So, to solve we change the division into multiplication.
Thus, R.H.S of the fraction will get reverse:


<em>Now, changing the improper fraction into mixed:</em>

Therefore, the answer as a mixed number is 
Answer
C. 14
Explanation
The area of triangle = 1/2(base)(height)
The height:
the height is the distance from point (2,-3) perpendicular to the base intersecting it at point (2,1)
the height is then the distance between the 2 points = 4
The base:
the base is the distance between points (7,1)and (0,1) = 7
The area:
the area = 1/2 x 4 x 7 = 28/2 = 14 units²

Step-by-step explanation:
the circumference of a circle is
2×pi×r
with r being the radius, which is always half of the diameter.
r = 1.8 / 2 = 0.9 cm
circumference :
2×pi×0.9 = 1.8×pi = 1.8 × 3.142 = 5.6556 cm ≈ 5.7 cm
