Answer:
9 months.
Step-by-step explanation:
Well we subtract the one time fee of $150 from $420
420-150=270
Now we need to divide $270 by $30, the price she pays every month.
270÷30=9
She has had the service for 9 months.
Answer:
- <u>x = -0.5 , x = -5.5</u>
Step-by-step explanation:
<u>Solving</u>
- -4x² = 24x + 11
- 4x² + 24x + 11 = 0
- 4x² + 24x + 36 - 36 + 11 = 0
- (2x + 6)² - 25 = 0
- (2x + 6)² = 25
- ⇒ 2x + 6 = ±5
<u>Case 1 : x = +5</u>
- 2x + 6 = 5
- 2x = -1
- x = -1/2
- <u>x = -0.5</u>
<u></u>
<u>Case 2 : x = -5</u>
- 2x + 6 = -5
- 2x = -11
- x = -11/2
- <u>x = -5.5</u>

Answer:
x = 4
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = , then using the upper 45°
sin45° = = = ( cross- multiply )
x = 4
