y/2
Step-by-step explanation:
is not included as a rational number !
<u>Step-by-step explanation:</u>
Here we have , following expressions & we need to identify which of the following is not a rational number . Let's find out:
We know that , Rational Number : A number which can be expressed in form of p/q , where q is not equal to zero !
Here Expressions are:
:

Therefore , It is not a rational number , as pi is included ! .
A circle is a collection of points all of which are on the circumference of the circle. If you use algebra and (x-h)^2 + (y-k)^2 = r^2 and the info contained in the coordinates (x,y) of each city, you can find h, k and r. Then r is the (equal) distance between each city and the center of the circle, where the new tower will be built.
Answer:
1,260°
Step-by-step explanation:
Nonagon is a 9 sided polygon
Exterior angle = 360 ÷ 9
= 40
Interior angle + exterior angle = 180
Interior angle = 180 - 40
= 140°
Sum of interior angles = 140° × 9
= 1,260°
Answer:
x+3≤20
x≤17
Step-by-step explanation:
let the amount of money left for misc expenditures = x
Number of pencils bought = 6
cost of each pencil = $0.50
Total expense on pencil = 6 x $0.50 = $3
Total expenditure =x+3
Maximum expenses allowed = $20
Hence
Total expenditure must be less than or equal to $20
Hence
x+3≤20
Subtracting 3 from both sides
x≤17
