Percentage by which the average value of mid sized car decreases each year = 8%
Retail value of a car today = v dollars
Amount of decrease in the value of the car after 1 year = (8/100) * v
= 2v/25 dollars
Then
The equation that represents the value of the car after 1 year = v - (2v/25) dollars
= (25v - 2v)/25 dollars
= 23v/25 dollars
So following this expression the value of the mid sized car can be easily determined after 1 year. I hope this is the answer you were looking for and the procedure is also clear to you.
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>

6, 12 18 24 30 36 42 48 54 60...
12, 24 36 48 60...
15, 30 45 60...
Voila. 60 shows up in all three. Its the first one to show up, hence lcm (least common multiple)
Answer:
x = 61
Step-by-step explanation:
x and 29 are complementary angles so they add to 90 degrees
x+29 = 90
Subtract 29 from each side
x+29-29 = 90-29
x = 61
