Is 2.89 rational or irrational
Answer:
Rational
Step-by-step explanation:
Rational numbers:
Rational numbers are such numbers that can be expressed in the form p/q, where the value of q must not be equivalent to 0.
Irrational numbers:
These numbers cannot be expressed in the form p/q, where the value of q must not be equivalent to 0.
[tex]\implies 2.89 = \dfrac{289}{100} \ \ \text{[In} \ \frac{\text{p}}{\text{q}} \ \text{form (\text{q}} \neq 0)]}[/tex]
Thus, 2.89 is a rational number.

I need help with a question.
Some students are playing a game. they roll a number cube and spin the arrow on a spinner on each turn.
-The number cube has sides numbered 1 through 6.
-The spinner has 3 equal-sized sections colored red(r), yellow(y), and blue(b).
This tree diagram shows the sample space for the possible outcomes of rolling a number cube one time and then spinning the arrow on the spinner once.(I'll put the diagram on the bottom)
What is the probability that, on a student's turn, the number cube will land with an even number on the top face and the arrow on the spinner will stop on the blue(b) section?
A. 1/3
B. 3/6
C. 3/18
D. 9/16
Answer:
option c
Step-by-step explanation:
3/6probability of number cube lands on an even number
1/3 probability that it will land on the spinner
multiply 1/3 x 3/6 =3/18
let me know if i get it correct
The probability that on a student's turn, the number cube will land with an even number on the top face and the arrow on the spinner will stop on the blue(b) section is P = 3/18
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
The probability of the number cube landing with an even number on the top face is 3/6 or 1/2 since there are three even numbers (2, 4, and 6) out of the six possible outcomes (1, 2, 3, 4, 5, and 6)
The probability of the arrow on the spinner stopping on the blue section is 1/3 since there is only one blue section out of the three possible outcomes
To find the probability of both events occurring together, we multiply the probabilities of each event:
P(even number and blue section) = P(even number) × P(blue section)
P(even number and blue section) = 1/2 × 1/3
P(even number and blue section) = 1/6
P = 3/18
Therefore, the probability that, on a student's turn, the number cube will land with an even number on the top face and the arrow on the spinner will stop on the blue section is 1/6.
Hence , the probability is P = 3/18

Mr Ahmad bought 2 fans and 3 table lamps for $540. Each fan cost 3 times as much as a table lamp. (a) Find the cost of each table lamp. (b) Find the cost of each fan.
Answer:
(a) $60
(b) $180
Step-by-step explanation:
Let the price of 1 table lamp be t.
Then the price of a fan is 3t.
2(3t) + 3t = 540
6t + 3t = 540
9t = 540
t = 60
A table lamp costs $60.
3($60) = $180
A fan costs $180.
A 400 pound metal star is hanging on two cables which are attached to the ceiling. The left hand cable makes a 18° angle with the ceiling while the right hand cable makes a 72° angle with the ceiling. What is the tension on each of the cables? (Round your answers to three decimal places.)
Answer:
left: 123.607 lbright: 380.423 lbStep-by-step explanation:
By balancing horizontal and vertical forces, we find the cable tensions to be ...
Ta = W·sin(b)/sin(a+b) . . . . . where W is the weight being held
Tb = W·sin(a)/sin(a+b)
Where Ta is the tension in the cable that makes an angle of 'a' with respect to the vertical, and Tb is the tension in the cable that makes an angle of 'b' with respect to the vertical.
__
The given angles are with respect to the ceiling, so the angles with respect to the vertical will be their compmements.
left cable (a)angle 'a' is 90° -18° = 72°
angle 'b' is 90° -72° = 18°
a+b = 72° +18° = 90°
Ta = (400 lb)sin(18°)/sin(90°) = 123.607 lb
right cable (b)Tb = (400 lb)sin(72°)/sin(90°) = 380.423 lb
_____
Additional comment
The nice expressions for cable tension come from the balance of forces.
vertical: Ta·cos(a) +Tb·cos(b) = W
horizontal: Ta·sin(a) = Tb·sin(b)
Solving the horizontal equation for Ta, we get ...
Ta = Tb·sin(b)/sin(a)
Substituting into the vertical equaiton gives ...
Tb·sin(b)cos(a)/sin(a) +Tb·cos(b) = W
Multiplying by sin(a) gives ...
Tb(sin(b)cos(a) +sin(a)cos(b)) = W·sin(a)
Using the trig identity for the sine of the sum of angles, we can rewrite this in the form shown above:
Tb = W·sin(a)/sin(a+b)
The problem is symmetrical with respect to 'a' and 'b', so the other tension is found by interchanging 'a' and 'b' in the equation:
Ta = W·sin(b)/sin(a+b)

Please solve this system of equations using the elimination method ONLY.

Part B)
Which number is the most convenient to multiply by when solving this linear system of equations by elimination?
A) -3
B) -1
C) 1
D) 2
Thank you in advance.
Answer:
D) 2
Step-by-step explanation:
When solving a system of equations using elimination, it often works well to start with them in a form that has all of the variables on the same side of the equal sign. Putting the second equation into standard form will accomplish that:
3x -2t = 42x +t = 5To eliminate one of the variables from the system, the equations are multiplied by numbers and combined (added or subtracted) so that the coefficient of one of the varibles becomes 0.
__
Choosing a multiplierThe coefficients of x are 3 and 2. If we are to eliminate x, we either need to multiply one equation by a rational number (2/3 or 3/2), or we need to multiply the two equations by two different numbers (2, 3).
The coefficients of y are -2 and 1. If we are to eliminate y, it is convenient to multiply the second equation by 2. This is probably the most convenient choice.
__
SolutionMultiplying the second equation by 2 and adding it to the first equation, we have ...
(3x -2t) +2(2x +t) = (4) +2(5)
7x = 14 . . . . . simplify; the y-variable is eliminated
x = 2 . . . . . . divide by 7
Using the original second equation, we have ...
2(2) -5 = -t = -1
t = 1
So, the solution is (x, t) = (2, 1).

Part A
Multiply each age with its corresponding frequency
19*2 = 3820*3 = 6021*1 = 2122*4 = 8823*1 = 23Then add up those products
38+60+21+88+23 = 230
We divide that sum over the total frequency of 11 (since 2+3+1+4+1 = 11).
mean = 230/11 = 20.9 approximately
Answer: 20.9Nice work on getting the correct answer.
============================================================
Part B
x = age of the new player
Adding x to the sum of the products 230, and then dividing over 11+1 = 12 will get us the new mean of 22.
The 230 represents the sum of the ages of the original eleven people. The expression 230+x represents the sum of the twelve ages.
So,
(230+x)/12 = 22
230+x = 12*22
230+x = 264
x = 264-230
