Answer:
Step-by-step explanation:
The area is the product of two dimensions.
If the ratio of sides is k, then the ratio of areas is k²
<u>We have:</u>
- k² = 200/8
- k² = 25
- k = √25
- k = 5
Correct choice is C
Answer:
a. s = .9*r
b. Yes, because the regular price is only being multiplied by a number without any additional operations.

Answer:
Step-by-step explanation:
The measure of an inscribed angle is exactly half the measure of the arc it forms. Thus, we have the following equation:
Solving, we get:
Plugging in 
into 
:
Sin(225)
225 degrees is in the 3rd quadrant. And in the third quadrant only tangent is positive, sin is negative.
For third quadrant, basic angle = 225 - 180 = 45
sin225 = - sin45
sin225 = - sin45 = -0.7071
sin 225° ≈ -0.7071
