The operation between a rational and a irrational number that results in a rational number is a multiplication, hence the expression ab could represent a rational number.
<h3>What are rational and irrational numbers?</h3>
If a number can be represented by a fraction, it is rational, otherwise, it is irrational.
The addition/subtraction of a rational and an irrational numbers is irrational, while the multiplication is rational, hence the expression ab could represent a rational number.

Answer:
5:05
6
10
Step-by-step explanation:
3:30 + 1 hour = 4:30
4:30 + 35 mins = 5:05 pm
5 days per 1 gallon, 30 days for :
30/5 = 6
500/50 = 10
. Correct option C)5.38
<u>Step-by-step explanation:</u>
Here we have , Find the value of x. O is the center of the circle. Round your answer to the nearest hundredth. picture is attached . Let's find out:
In the given figure , Let's draw a line from center to the point where cord of length 8 unit is touching the circle or intersecting or , where this chord finishes . This line is radius of circle and is denoted by x , So now we have a right angle triangle with dimensions as :
![Perpendicular =3.6\\Base=\frac{8}{2}=4\\Hypotenuse=x](https://tex.z-dn.net/?f=Perpendicular%20%3D3.6%5C%5CBase%3D%5Cfrac%7B8%7D%7B2%7D%3D4%5C%5CHypotenuse%3Dx)
By Pythagoras Theorem ,
![Hypotenuse^2=Perpendicular^2+base^2](https://tex.z-dn.net/?f=Hypotenuse%5E2%3DPerpendicular%5E2%2Bbase%5E2)
⇒ ![x^2=(3.6)^2+(4)^2](https://tex.z-dn.net/?f=x%5E2%3D%283.6%29%5E2%2B%284%29%5E2)
⇒ ![x=\sqrt{(3.6)^2+(4)^2}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B%283.6%29%5E2%2B%284%29%5E2%7D)
⇒ ![x=\sqrt{12.96+16}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B12.96%2B16%7D)
⇒ ![x=\sqrt{28.96}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B28.96%7D)
⇒ ![x=5.38](https://tex.z-dn.net/?f=x%3D5.38)
Therefore ,
. Correct option C)5.38
Find the GCF (Greatest Common Factor)
GCF = 2x
Factor out the GCF (Write the GCF first and then, in parentheses, divide each term by the GCF.)
2x (2x^3/2x + 4x^2/2x + 6x/2x)
Simplify each term in parentheses
-2x(x^2 + 2x + 3)
<u>Answer D. -2(x^2 + 2x + 3)</u>
Answer:
1/36
Step-by-step explanation:
If a cube rolls and it landed on one it’s 1/6 if u rolled he same cube and got one too then it’s still 1/6 so now u just multiply them
Hope this helps
