Answer:
a. 60%
b. 37%
c. 3%
Step-by-step explanation:
a. 72/ 120 then multiply by 100
b. 120- 72 + 4 = 44/ 120 x 100
c. 4/120 x 100
(5+x)/x
K*H = 1/x(5+x) or (5+x)1/x which = (5+x)/x because (5+x)1/x = [(5+x)/1] * [1/x] and anything multiplied by one is equal to itself.
Required area = lb + 2 × h ( l + b)
= 4 × 3 + 2 × 7 (4 + 3)
= 12 + 14 × 7 = 12 + 98 = 110 m²
Cost of white-washing at the rate of $6/m²
= $ 110 × 6 = $ 660
The number of miles run in all 6 days: 6 * 12 3/4
Change 12 3/4 to improper fraction = (12*4 + 3) / 4 = (48 + 3) / 4 = 51 / 4
6 * 51/4
3 * 51/2 = 153/2 = 76.5
Miles run in all = 76.5 Miles.
Hope this explains it.
