BY taking the square root you can find each of them as follows:
1. sqrt(144) = 12
2. sqrt(25/289) = 5/17
Answer:
1) Is 90° because that's what the little square in the corner means.
2) Is 60° because if you take everything to the right of the vertical line and add them up, and then subtract the total from 180° you can find the missing angle.
3) Is 30° because if you use what's below the horizontal line and do the same thing as number 4 (add the existing angles together and subtract the total from 180) you can find the missing angle.
4) Is 20° because if you add the existing angles together (40° + 90° + 30°), you'll get 160°, and since the diagonal line that's separating everything from 40° to 30° looks as though it equals 180°, you'd subtract 160° from 180° in order to get the missing angle.
5) Is also 90° because the angle across from it (1) looks to be around the same size.
I solved for each in the following order:
1, 5, 4, 3, 2.
I hope this helps. Also please let me know if I got something wrong or if you still need help :)
Hi,
Here is the solution.
3 years = 36 months
Leased amount for 3 years = $3000 + 36*350
= $3000 + $12600
Leased amount for 3 years = $15600
Residual value = $12000
Assume you didn't buy the car, you took it for lease, so your expense = $15600.
Now Assume you bought the car for $21,000.
After using 3 years, you can sell it for $12000.
Your expense = $21,000 - $12,000 = $9000.
Conclusion:
It is less expensive to buy the car.
The cost for buying the car and selling it after 3 years = $9000.
Hope you will understand the steps. Thank you :)
