Answer:
rational numbers are real numbers that statement is true
Step-by-step explanation:
because all rational numbers are belong to real number ,
real number contain all type of numbers rational and real number.
The answer to both the subparts using the circumference of the circle is:
- (A) If an athlete runs around the track then the athlete traveled (168.78+73π)m.
- (B) The area of green space on the track is 0.64m².
<h3>What is a length of a rectangle?</h3>
- The length of the rectangle is traditionally thought of as being the longer of these two dimensions, however, when the rectangle is depicted standing on the ground, the vertical side is typically referred to as the length.
What is a circumference of a circle?
- The distance along a circle's perimeter is referred to as its circumference.
- Circumference of the circle formula: C = 2πr.
Here,
(A) A circuit of a racetrack is equal to the sum of the two lengths of a rectangle and the circumference of the circle.
We get:
- = 84.39 * 2 + 73π
- = (168.78 + 73π)m
(B) Let the area of the green space of the track is x.
Then, calculate as follows:
- 168.78 + xπ = 400
- x = (400 - 168.78)/π
- x = 73.64m
So, the inner circle of distance is 73.64 - 73 = 0.64m.
Therefore, the answer to both the subparts using the circumference of the circle is:
- (A) If an athlete runs around the track then the athlete traveled (168.78+73π)m.
- (B) The area of green space on the track is 0.64m².

Answer:
The correct option is y ≤1/3 x – 4
Step-by-step explanation:
If you look at the attached graph you will see that the inequality is the shaded area below the solid line.
The slope of the line is positive which is 1/3.
The y intercept is equal to -4
Thus the inequality must be:
y ≤1/3 x – 4
Therefore the correct option is:
y ≤1/3 x – 4 ....
check the picture below.
