Answer: C) 3pi
pi is irrational, and so is 3pi
The expression 3pi+0.4 is overall irrational as well.
If x is irrational and y is rational, then x+y is irrational
This is why choice C is the answer.
The other answer choices are rational values which would make the sum rational, so that's why we can rule them out.

Select the correct answer from each drop-down menu. The velocity, v, in meters/second, of an object with a mass of m, in kilograms, and kinetic energy of K, in joules, is given by this equation. Use the equation to complete this statement. The kinetic energy of a ball with a mass of 2 kilograms that is rolling at a velocity of 5 meters/second is joules.
Answer:
25
Step-by-step explanation:
The kinetic energy of a ball with a mass of 2 kg that is rolling at a velocity of 5 m/s is 5 Joules
Calculating Kinetic energyFrom the question, we are to determine the kinetic energy of the ball
From the given equation for the velocity,
[tex]v = \sqrt{\frac{2K}{m} }[/tex]
We will make K the subject of the equation
[tex]v = \sqrt{\frac{2K}{m} }[/tex]
Take the squares of both sides
[tex]v^{2} ={\frac{2K}{m} }[/tex]
Multiply both sides by m
[tex]mv^{2} ={\frac{2K}{m} } \times m[/tex]
[tex]mv^{2} =2K[/tex]
∴ [tex]K = \frac{1}{2} mv^{2}[/tex]
Now, for the kinetic energy of a ball with a mass of 2 kilograms that is rolling at a velocity of 5 meters/second
That is,
m = 2 kg
and v = 5 m/s
Putting the parameters into the equation, we get
[tex]K = \frac{1}{2} \times 2 \times 5^{2}[/tex]
K = 25 J
Hence, the kinetic energy of a ball with a mass of 2 kg that is rolling at a velocity of 5 m/s is 5 Joules

144 students enter a spelling bee, but only 1/6 of the group will make it into the semi-final round, and only 2/3 of that group will make it into the final round. How many students will enter the final round of the spelling bee?
I know I'm sorry the person that made this problem did a terrible job on wording it. HELP!!!!!!
Answer:
Hey buddy, here is your answer. Hope it helps you.
Step-by-step explanation:
144 students enter a spelling bee contest.
Step 1
For the semi final round we are told that only 1/6 of the group will make it into that round.
This is calculated as
1/6 × 144/students = 24 students.
This means that only 24 students would make it into the semi final rounds.
Step 2
We are also told in the question that only 2/3 of THAT group would make it into the final round.
" THAT" group been referred to in the question means the number students that made it to the semi final round
This is calculated as
2/3 of that group( the group that made it to the semi finals)
= 2/3 × 24 students
= 16 students.
Therefore, the number of students that will enter the final round of the spelling bee is 16 students.

Find the Error A student graphs the relationship y = x on a coordinate plane. She says the slope is O because there is no coefficient. Find her
mistake and correct it.
Answer:
y=x times factor of 12 abstracted by -93
Step-by-step explanation:
The slope is the ratio of y's coordinate to x's coordinate thus the slope of y = x will be y/x = 1.
What is the slope?A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
A linear equation or function is given as ;
y = mx + b
Now,
At x = 0 ⇒ y = b so it will be a y-intercept.
As per the given, y = x
The x's coefficient is 1 thus slope will be 1.
Or, y/x = 1
Hence "The slope is the ratio of y's coordinate to x's coordinate thus the slope of y = x will be y/x = 1".

The value of y varies directly with x. If x=6, then y=21
.
Find the value of x when y=70
Answer:
Direct proportionality
If the value of y varies directly with x, the value of x when y=70 is 20.
Given that, the value of y varies directly with x.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
We know that, the value of y varies directly with x
y ∝ x
⇒ y = kx
⇒ k = y/x
⇒ k = 21/6
⇒ k = 7/2
So, k = y/x
7/2 = 70/x
⇒ 1/2 = 10/x
⇒ x = 20
Therefore, if the value of y varies directly with x, the value of x when y=70 is 20.

A square root function, that is stretched by a factor of 3, and shifted 4 units left and 6 units up.
Answer:
The square root function will turn to;
y = 3 √(x + 4) + 6
Step-by-step explanation:
Let the square root function be ;
y = √x
Now, let’s stretch this by a factor of 3
This means we are dilating by a factor of 3
Mathematically, this will be
y = 3 * √x = 3 √x
Shifting this 4 units up means that we are extending the x-axis value by 4 units
That will be ;
y = 3 √x + 4)
Now shifting this 6 units up, we finally will have;
y = 3 √(x + 4) + 6
