RSTV is a quadrilateral

Interior angles of a quadrilateral sum to 180

<u>Sum of given angles:</u>

  • 2n + 6n + 2n + 5n = 180°
  • 15n = 180°
  • n = 12°

<u>The angles are:</u>

  • 2*12°= 24°, 6*12° = 72°, 2*12° = 24°, 5*12° = 60°

(3)

<u>Sum of angles of a regular 18-gon:</u>

  • S = 180°(18 - 2) = 2880°

<u>Each interior angle is:</u>

  • 2880°/18 = 160°

(4)

<u>Sum of interior angles of a convex heptagon (7-sided polygon):</u>

  • S = 180°(7 - 2) = 900°

(5)

Sum of exterior angles of any polygon is 360°

<u>Each exterior angle of a regular nonagon (9-sided polygon) is:</u>

  • 360°/9 = 40°

Nathan opens a new savings account and makes an initial deposit of $400.
AfilCa [17]

Answer:

The answer to the first one is 6

Step-by-step explanation:

If the time frame given is 9 months, then we can find that 9 months is 3/4 of a year. 3/4 x 2% = 0.015.     0.015 x 400 = 6. He would have made 6 dollars in 9 months.

Answer the the second one:

4.5% x 5 (years) = 0.225.     0.225 x 10,000 = 2,250. Since this is a car loan and not a bank interest for example, we add it to the total cost. I'm pretty sure its the third one.

Ashley took $20 out on her savings account each week on Friday. How many weeks ago did she have at least $250 in her account
tatuchka [14]
If she took $20 out of her savings account, given the information, she could easily have no money remaining now. Given this, we'll assume the current value of her account is the minimum it can be. Now you just need to find how many times her withdrawal can factor into the original amount, $250. Therefore, t=250/20= 12.5. Since it's asking for a number of weeks, the answer can't be a decimal, so your final answer is 12 weeks.
