Answer:
The area of circle 1 is 9 times greater than area of circle 2.
Step-by-step explanation:
Given that:
Radius of circle 1 = 12
Area of circle 1 = πr²
Area of circle 1 =
Area of circle 1 = 452.16
Radius of circle 2 = 4
Area of circle 2 =
Area of circle 2 = 50.24
Let,
x be the number of times circle 1 is bigger than circle 2.
Area circle 1 = x * Area circle 2
Hence,
The area of circle 1 is 9 times greater than area of circle 2.
The measures of the angles are given as follows:
<h3>What is the value of x?</h3>
Angle ABD is the sum of angles BCD and ABC, hence:
ABD = BCD + ABC.
We replace the measures to find the value of x, hence:
6x - 9 + 4x - 1 = 82.
10x - 10 = 82.
10x = 92.
x = 9.2.
<h3>What are the measures of the angles?</h3>
With x, we can find the measures of the angles, as follows:
- ABC = 6(9.2) - 9 = 46.2º.
- CBD = 4(9.2) - 1 = 35.8º.

Answer:
6
Step-by-step explanation:
2 * (729* 1/243) = 2 * 3 = 6
Equation:
distance + distance = 2250 miles
3x + 3(x-110) = 2250
6x - 330 = 2250
6x = 2580
x = 430 mph (rate of the westbound plane)
x-110 = 320 mph (rate of the eastbound plane)
