Answer:
(i) 8.5 × 10^-12
(ii) 9.42 × 10^-12
(iii) 602 × 10^15
(iv) 8.37 × 10^-9
(v) 3.186 × 10^10
Step-by-step explanation:
(i) 0.0000000000085
= 0.0000000000085 × 10^12/10^12
= 8.5/10^12
<u>= 8.5</u><u> </u><u>×</u><u> </u><u>10^-12</u>
(ii) 0.00000000000942
= 0.00000000000942 × 10^12/10^12
= 9.42/10^12
<u>= 9.42</u><u> </u><u>×</u><u> 10^-12</u>
(iii) 6020000000000000
<u>= 602 </u><u>×</u><u> </u><u>10^15</u>
(iv) 0.00000000837
= 0.00000000837 × 10^9/10^9
= 8.37/10^9
<u>= 8.37</u><u> </u><u>×</u><u> </u><u>10^-9</u>
(v) 31860000000
<u>= 3.186 </u><u>×</u><u> 10^10</u>

Answer:
The answer is at 8:00 o’clock.
Step-by-step explanation:
So the Martinez family started 30 min after the Smith’s family. Smith’s family started one hour before Carson’s family. So it means the Smith’s family started at 7:30 and Martinez family started 30 min later. It means at 8:00 o’clock.
Set up a proportion of acres to days. 1/2 acre is to 4 days as 2 3/4 acres is to x days.
x= # days to clear 2 3/4 acres
2 3/4 to improper fraction= 11/4
(1/2)/4 = (11/4)/x
cross multiply
(1/2 * x) = (4 * 11/4)
on the right, the 4 "cancels out"
1/2x= 11
divide both sides by 1/2
x= 11 ÷ 1/2
to divide fractions, multiply by reciprocal/inverse of 1/2
x= 11 * 2/1
x= 22 days
ANSWER: It would take 22 days to clear 2 3/4 acres.
