Answer:
The answer to your question is the letter D.About 22
Step-by-step explanation:
Data
China's area = 3 700000 mi²
Asia's area = 17 200000 mi²
Process
1.- Consider the Asia's area as 100% and use proportions to solve this problem
17 200000 -------------------------- 100 mi²
3 700000 -------------------------- x
x = (3700000 x 100) / 17200000
- Simplification
x = 370000000 / 17200000
-Result
x = 21.51 ≈ 22
The answer is 1. 3/8x = 510
We know this because if we are eating 3/8 of the pizza, and we assume that the total number of calories in the pizza is x, then 3/8 of x will give us the amount of calories that we ate, which is 510. Therefore when we write this equation we get:
3/8x = 510 (3/8 of x is equal to 510)
The secant of circle D is the 'line GH'. Where the line segment EF is the diameter of the circle, line segment DC is the radius, and the ray AB is the tangent of the given circle.
<h3>What is the secant of the circle?</h3>
The line that passes through the circle and touches the circle at two points is said to be a secant line of the circle.
<h3 /><h3>Which is the secant line in the given circle D?</h3>
The given circle D has a center at D.
The radius of the circle is given by the line segment CD
The diameter (or) the longest chord of the circle is given by the line segment EF
The ray AB passes touches the circle at point B, which is called the tangent of the circle.
Where the line GH passes through the circle and touches at two points. So, this line GH is said to be the secant of the circle.
