Answer:50
Step-by-step explanation:
3/5 = 3 ÷ 5 = 0.6
30 ÷ 0.6 = 50
otra explicacion:
30/1 ÷ 3/5= 30/1 x 5/3 = 150/3 = 50
5 pencils to 2 pens is 5/2 in simplest form
The measure of the interior angle at vertex C is D. 144.
<h3>How to calculate the angle?</h3>
Based on the information given, the angle will be calculated thus:
8x + 8x + 8x + 3x + 3x = (5 - 2) × 180
30x = 540
Divide both side by 30
30x/30 = 540/30
x = 18
Therefore, at vertex C, we have 8x. This will be:
= 8x
= 8 × 18
= 144

The answer is x^2 + y^2 = 9
For this problem, you should use the equation of circle:
(x - h) ^2 + (y - k)^2 = r^2
where (h,k) is the coordinates of the center
and r is radius
(x - 0) ^2 + (y - 0)^2 = 3^2
Therefore:
x^2 + y^2 = 9
