Step-by-step explanation:
The decimal number 3.4 terminating decimal. So, it is rational number. Therefore, option B is the correct answer.
What is the rational number?Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0. This means that rational numbers include natural numbers, whole numbers, integers, fractions of integers, and decimals (terminating decimals and recurring decimals).
A) The decimal number 3.456733244… is not repeating and non recurring
So, it is irrational number
B) The decimal number 3.4 terminating decimal
So, it is rational number
C) Infinity is not a rational number because it is undefined as far as being an integer.
D) ∛4 =1.58740105197 is not repeating and non recurring
So, it is irrational number
The decimal number 3.4 terminating decimal. So, it is rational number. Therefore, option B is the correct answer.

Can someone write a real-world problem for this?
Answer:
2.5(x)+6=3.25(x)+3 4=x. Real world problem below
Step-by-step explanation:
Nico is organizing a party. Going skating, admission is 6 dollars, and each person pays 2.5 dollars for a pair of skates. If he has 3 other people in his group, the equation is 2.5(4)+6=24. He is also looking at going to a trampoline park. It is 3 dollars to get in, and 3.25 per person for an hour on the trampolines. This equation can be shown as 3.25(4)+3 which equals 24.

A passenger plane left the airport and flew
south at an average speed of 425 mph. A
cargo plane left sometime later flying in
the opposite direction with an average
speed of 302 mph. After the passenger
plane had flown for eight hours the planes
were 4608 mi. apart. How long did the
cargo plane fly?
Answer:
The cargo plane flew 1208 miles, and it took 4 hours.
Step-by-step explanation:
4608 miles is the distance between the passenger plane and the cargo plane.
This distance can be expressed as the sum of the distance that the passenger plane had flown and the distance that the cargo plane had flown.
Distance Apart = Distance Flown (Passenger) + Distance Flown (Cargo)
So, to find the distance flown by the cargo plane, we need both the distance between the 2 planes and the distance flown by the passenger plane.
We know that the distance apart is 4608 mi.
How far did the passenger plane fly?We can find the distance flown by the passenger plane by multiplying its speed by the time it was flying.
[tex]distance = speed * time[/tex]
Speed = 425 mph
Time = 8 hours
[tex]distance\ (passenger) = 425 * 8\\distance\ (passenger) = 3400[/tex]
The passenger plane flew 3400 mi.
How far did the cargo plane fly?Now we can find the distance flown by the cargo plane:
Distance Apart = Distance Flown (Passenger) + Distance Flown (Cargo)
[tex]4608 = 3400 + distance[/tex]
Subtract 3400 from both sides:
[tex]1208 = distance[/tex]
The cargo plane flew 1208 miles.
For how long did the cargo plane flow?If we want to find for how long it flew, we can divide the distance by its speed.
[tex]distance = speed * time[/tex]
[tex]time = \frac{distance}{speed}[/tex]
Distance = 1208 mi
Speed = 302 mph
[tex]time = \frac{1208}{302} = 4[/tex]
Answer: The cargo plane flew 1208 miles, and it took 4 hours.

are collinear, CE = 15.8 centimeters, and DE=
3.5 centimeters.
Given :
C, D, and E are col-linear, CE = 15.8 centimetres, and DE= 3.5 centimetres.
To Find :
Two possible lengths for CD.
Solution :
Their are two cases :
1)
When D is in between C and E .
. . .
C D E
Here, CD = CE - DE
CD = 15.8 - 3.5 cm
CD = 12.3 cm
2)
When E is in between D and C.
. . .
D E C
Here, CD = CE + DE
CD = 15.8 + 3.5 cm
CD = 19.3 cm
Hence, this is the required solution.
Which rays form the 65 angle in this figure?
Answer:
BD and BC
Step-by-step explanation:
The angle is between this two lines
The rays BD and BC form the angle 65° in the figure.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
When two lines or rays intersect at a single point, an angle is created.
Here, the angle measure is 65°.
An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
And it is created between two rays.
And those rays are BD and BC.

Write a sentence describing each of the following probabilities. (Note: A' = the complement of event A) P(A or A') = 1 P(A and A') = 0
Answer:
The following properties hold for all events A, B.
• P(∅) = 0.
• 0 ≤ P(A) ≤ 1.
• Complement: P(A) = 1 − P(A).
• Probability of a union: P(A ∪ B) = P(A) + P(B) − P(A ∩ B).
For three events A, B, C:
P(A∪B∪C) = P(A)+P(B)+P(C)−P(A∩B)−P(A∩C)−P(B∩C)+P(A∩B∩C).
If A and B are mutually exclusive, then P(A ∪ B) = P(A) + P(B).
• Conditional probability: P(A | B) = P(A ∩ B)
P(B)
.
• Multiplication rule: P(A ∩ B) = P(A | B)P(B) = P(B | A)P(A).
• The Partition Theorem: if B1, B2, . . . , Bm form a partition of Ω, then
P(A) = X

P(A ∩ Bi) = X

P(A | Bi)P(Bi) for any event A.
As a special case, B and B partition Ω, so:
P(A) = P(A ∩ B) + P(A ∩ B)
= P(A | B)P(B) + P(A | B)P(B) for any A, B.
• Bayes’ Theorem: P(B | A) = P(A | B)P(B)

More generally, if B1, B2, . . . , Bm form a partition of Ω, then

A) -9 1/2
B) 1 1/2
C) 2 1/2
D) 10 1/2
Answer:
B is the correct answer for this question
Step-by-step explanation:
The number that could represent point Q is to be considered as the option c. 2 1/2.
Calculation of the number:Since
p = -4
q could be 6.5 units to the right or to the left of point p.
So, to the right it should be like
=p + q
= -4 + 6.5

What is the answer to.. –2m = 8 − m
Answer:
-8
Step-by-step explanation:
Solve the equation:
-2m = 8 - m
-2m + m = 8
-m = 8
m = -8
If you would like to check the answer, plug the value of m back into the equation:
-2 (-8) = 8 - -8
16 = 16
Answer:
m = -8
Step-by-step explanation:
add m to both sides
-2m + m =8 - m + m
simplify
-m = 8
divide sides by -1
-m/-1 = 8/-1
simplify
m = -8

Let w represent the width of the playing field in yards. Then the length is 3w-3. The perimeter is given by ...
P = 2(L+W)
362 = 2((3w-3) +w)
181 = 4w -3

Answer:
y = [tex]\frac{1}{9}[/tex] x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
y = - 9x + b ← is in slope- intercept form
with slope m = - 9
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-9}[/tex] = [tex]\frac{1}{9}[/tex] , thus
y = [tex]\frac{1}{9}[/tex] x + b ← is the partial equation
To find b substitute (- 18, 3) into the partial equation
3 = 2 + b ⇒ b = 3 - 2 = 1
y = [tex]\frac{1}{9}[/tex] x + 1 ← equation of perpendicular line
