Everything is rational
Answer:
the rational numbers are 6, 3/4, 1.5, 103, 0.863 so all of them.
Step-by-step explanation:
Any number that can be written, numbers like 2.3373648489 with no pattern or rationality are not rational.
However number like 2.3333 are rational because you can predict the pattern.

What is the problem, can you write it better pls?
Answer:
x = - 3 and x = 1
Step-by-step explanation:
4x - 2 - 2x = x - 5, that is
2x - 2 = x - 5 ( subtract x from both sides )
x - 2 = - 5 ( add 2 to both sides )
x = - 3
----------------------------------------
- (x + 3) = 2x - 6 ← distribute left side
- x - 3 = 2x - 6 ( subtract 2x from both sides )
- 3x - 3 = - 6 ( add 3 to both sides )
- 3x = - 3 ( divide both sides by - 3 )
x = 1
Mario made 2 goals for every 5 shots on goal. What is the probability that Mario would make 2 goals on two shots?
Answer:
16%
Step-by-step explanation:
To calculate this we first need to calculate the probability of Mario scoring for every individual shot that he takes. Since he makes 2 goals for every 5 shots on average, we simply divide these numbers to get the probability of a goal per shot.
2 / 5 = 0.4 ...multiply by 100 to get percentage value
0.40 * 100 = 40%
We see that the probability of scoring a goal per shot is 40%. Now we need to multiply this probability twice to get the probability of scoring 2 consecutive goals in two shots.
0.40 * 0.40 = 0.16 ... multiply by 100 to get percentage value
0.16 * 100 = 16%
Answer:
16%
Step-by-step explanation:
I know that 2/5 = 0.4 or 40%
and 0.4 x 0.4 = 0.16
or 16%

the ratio with the bigger number first would be the answer because it's bigger than 1 3.
Answer:
His Son
Step-by-step explanation:
2/7=0.29
1/3=0.33
In total 19/21 of the laundry still needs to be complete.
9.5% is done
90.5% needs to be done between the both of them.
71.43% of Mr. Vardar's laundry needs to be done.
66.67% of his sons needs to be done.
If the expression
(3v+7) - (8v+6)
needs to be equivalent to
(-5+n)
What is the value of n?
Answer:
n = 1
Step-by-step explanation:
So the first step is to simplify the top equation:
(3v + 7) - (8v + 6)
distribute the negative sign to get rid of the second parentheses:
3v + 7 - 8v - 6
now, combine like terms
-5v + 1
Since it says it needs to be equivalent to (-5v + n), n is 1
How many solutions does the following. system of equations have? 6x-3y= -9 y=2x+3. one solution, infinitely many solutions or no solution?
Answer:

Step-by-step explanation:
Kenji drives 18.4 miles in 16 minutes. He passes a sign, which gives the speed limit as 60 mph. By how much, in mph, did Kenji's average speed exceed the speed limit?
The amount of speed by which kendri exceeded the speed limit is; 9 mph
We are given;
Distance; d = 18.4 miles
Time; t = 16 minutes = (16/60) hours
Now, the formula for speed is;
Speed = distance/time
Thus, let's Calculate kenji's speed;
Kenji's speed = 18.4/(16/60)
Kenji's speed = 69 mph
We are told that the speed limit is to be 60 mph, this means that kendri exceeded the speed limit by;
69 - 60 = 9 mph

Select the solution(s) of log2x=1−log(x+4).
Step-by-step explanation:
log2x = 1 - log(x+4)
log2x = log10 - log(x+4)
log2x = log[10/(x+4)]
2x = 10/(x+4)
2x(x+4) = 10
2x² + 8x - 10 = 0
÷2 both sides of equation
x² + 4x - 5 = 0
(x+5)(x-1) = 0
x = -5, 1
x isn't be -5 because logA, A need to be > 0
So, x value is 1

A certain model car has a keypad with 5 numbers on the door. To open the door, 5 numbers must be entered in the correct
order and no number can be used more than once. What is the probability that someone could guess the correct code?
OA. Ito
OB.
OC.
OD.
Answer: A. [tex]\dfrac{1}{120}[/tex]
Step-by-step explanation:
Total digits on keypad = 5
According to permutation,
If repetition of digits is not allowed then the number of 5-digits passwords can be formed = 5!
= 5 x 4 x 3 x 2 x 1 [n!=n x (n-1) x (n-2)x ... x 1]
=120
The probability that someone guesses the correct code = [tex]\dfrac{\text{Number of correct codes}}{\text{Total possible codes}}[/tex]
[tex]=\dfrac{1}{120}[/tex]
Hence, the correct option is A.

Which expression is equivalent to (-5/6) / (10/3)?
Answer:
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=-\frac{1}{4}[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}[/tex]
Let us solve the expression
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=\frac{-\frac{5}{6}}{\frac{10}{3}}[/tex]
Apply fraction rule: [tex]\frac{-a}{b}=-\frac{a}{b}[/tex]
[tex]=-\frac{\frac{5}{6}}{\frac{10}{3}}[/tex]
Divide fractions: [tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}[/tex]
[tex]=-\frac{5\cdot \:3}{6\cdot \:10}[/tex]
Multiply the numbers: [tex]6\cdot \:10=60[/tex]
[tex]=-\frac{5\cdot \:3}{60}[/tex]
Multiply the numbers: [tex]5\cdot \:3=15[/tex]
[tex]=-\frac{15}{60}[/tex]
Cancel the common factor: 15
[tex]=-\frac{1}{4}[/tex]
Therefore, we conclude that the equivalent expression is:
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=-\frac{1}{4}[/tex]
