Step-by-step explanation:
1500 divided by 5
<u>Answer</u>
C. 4 + 6
D. 3.15151515.. + 4.6
E. √64 × √25
<u>Explanation</u>
A rational number is a number that can be expressed as a quotient or a fraction. That is it can be written as a/b.
π×6 = 6π ⇒ can not be written as a rational number.
√3 + √5 ⇒ the sum of two irrational numbers can not be rational.
4 + 6 = 10. Ten is a rational number. it can be written as 10/1
3.15151515.. + 4.6 = 104/33 + 23/5
= 1279/165
√64 × √25 = 8×5=40 This can be written as 40/1

Answer:
Step-by-step explanation:
Area of plane figures
Being r the radius of a circle, the area of a sector defined by an angle is
If a is the repeated side of an isosceles triangle and is the angle they define, then the area of the triangle is
The figure shows a circle with radius of r=7 cm. The white area is equal to the area of the circle minus the blue area
The area of the circle is
The blue area is the sum of the sector defined by the angle (360-150)= and the triangle. An angle of is equivalent to
The area of the sector is
The area of the triangle with center angle 150^o is
The blue area is
Finally, the white area is
