Answer:
5/18 is a rational number because a rational number is any integer,fraction terminating decimal,or repeating decimal.
5/18 is rational number.
What is Rational Number?The word "ratio" is where the word "rational" first appeared. Rational numbers are therefore closely tied to the idea of fractions, which stand for ratios. In other terms, a number is a rational number if it can be written as a fraction in which the numerator and denominator are both integers.
Any number of the form p/q, where p and q are integers and q is not equal to 0, is a rational number. The letter Q stands for the set of rational numbers. Look at the following illustration to see what a rational number looks like.
Given:
5/18
For rational we need to first divide the fraction and then check whether the fraction is a decimal or not.
Or if it is a decimal then it is terminating or non terminating
5/18 = 0.2777777777777778
Hence, it is terminating because rational number is any integer, fraction terminating decimal or repeating decimal.

. On the opening night of a new movie, a local movie theater sold 630 tickets and filled 90% of the seats in the theater. How many seats are in the movie theater?
Answer:
700 seats
Step-by-step explanation:
- If 630 tickets filled 90% of the seats, [tex]x[/tex] tickets filled 100% of the seats
multiply 630 by 630 tickets = 90/100
- Set up a proportion
630 tickets/90 = [tex]x[/tex] tickets/100
[tex]x[/tex] = 700 tickets = 700 seats

please help find the top angle
Answer:
130 degrees
Step-by-step explanation:
So u can see those little lines on two of the sides of the triangle, it means that it's congruent also meaning the same length, and if u didn't, the angles had to be the same in order for the sides to be the same length. So the other missing angle degree is also 25 degrees. A triangle is 180 degrees, so with this info:
25 + 25 + 4x + 2 = 180
4x + 52 = 180
4x = 128
x = 32, now we have x so replace the x in the equation with 32
4(32) + 2
128 + 2

Carlos pays $25 for skis and borrows the remaining amount. The loan payments are $75 every 3 months for 1/1/2 years. The interest rate is 16.2%/a compounded quarterly. What was the selling price of the skis?
Answer:
$417.52
Step-by-step explanation:
Present value of annuity = P * {1-[1/(1+r)^n]/r}
P =Periodic payment i.e. 75
r = rate of interest per period i.e. 16.2% /4 = 4.05% or 0.0405
n =no. of compounding period i.e. 1.50*4 =6
Present value of annuity = Loan amount
Present value of annuity = 75 * {1-[1/(1+0.0405)^6]/0.0405}
Present value of annuity = 75 * {1-[1/(1.0405)^6]/0.0405}
Present value of annuity = 75 * {1-[1/1.268973)/0.0405}
Present value of annuity = 75 * (1-0.78804)/0.0405
Present value of annuity = 75 * (0.21196/0.0405)
Present value of annuity = 75 * 5.23361
Present value of annuity = 392.52
Loan amount = $392.52
Selling price = $392.52 + $25.00
Selling price = $417.52
Thus, the selling price of the skis is $417.52

This week is representative of how many hours Ricki will work each week during Summer Break. If she earns $9 per hour and there are 12 weeks in summer vacation, what will Ricki’s gross earnings be? Explain your reasoning. Please answer ASAAAAP
Answer:
The answer would be $18,144.
Step-by-step explanation:
First you have to figure out how many hours are in one week. 168 hours are in one week. The problem is asking us for 12 weeks. You would have to multiply 168 by 12 to see how many hours it would be. 168 times 12 is 2,016. Ricki earns $9 every hour. Next, you would have to multiply the 2,016 by 9 to give you 18,144.

En el siguiente esquema se presentan en rojo las diferentes rutas que existen para llegar de una ciudad a otra. Por ejemplo, para llegar de la ciudad B a la ciudad C hay 4 posibles rutas. Si se quiere viajar desde la ciudad A a la ciudad D, ¿por cuántas rutas se podría ir? * A. 14 B. 36 C. 12 D. 24
Answer:
La respuesta es D. 24
Step-by-step explanation:
Falta el esquema. Lo adjunto en la resolución de la pregunta.
En el esquema se puede ver que hay 3 maneras de ir desde la ciudad A a la ciudad B, 4 maneras de ir desde la ciudad B hacia la ciudad C y finalmente 2 maneras de ir desde la ciudad C hacia la ciudad D.
Necesitamos saber por cuántas rutas se podría ir si se desea viajar desde la ciudad A a la ciudad D.
Utilizaremos el principio de multiplicación para responder a ésta pregunta ⇒
Supongamos que estamos realizando un experimento [tex]N[/tex] el cuál está conformado por una serie de sub - experimentos [tex]m_{1},m_{2},...,m_{n}[/tex].
Ahora, cada uno de estos sub - experimentos se puede desarrollar de [tex]n_{1},n_{2},...,n_{n}[/tex] maneras diferentes respectivamente. Entonces, el número total de maneras diferentes en las que el experimento [tex]N[/tex] se puede llevar a cabo se calcula como [tex]n_{1}[/tex] x [tex]n_{2}[/tex] x . . . x [tex]n_{n}[/tex]
Ahora bien, siguiendo con ésta idea escribimos :
3 x 4 x 2 = 24
''3'' porque es el número de rutas distintas para ir de A hacia B
''4'' porque es el número de rutas distintas para ir de B hacia C
Y finalmente ''2'' porque es el número de rutas para ir desde C hacia D
Si hacemos éste producto el resultado es 24 y por lo tanto la opción correcta es D. 24

I thought of a two-digit number. The unit digit of my number is a prime number, and the tens digit is four times as big as the unit digit. What is my number?
Please help! I'm very bad at these "what's my number" problems, so please respond ASAYC! (as soon as you can)
====================================================
Explanation:
Let A be the tens digit and B be the units digit
We can write the number as AB. So if A = 9 and B = 2 for instance, then the number is AB = 92. Keep in mind I'm not multiplying A and B here.
"The unit digit is a prime" means B could be any of these values {2,3,5,7}. We only list the single digit primes. The value 1 is not prime.
Now multiply each of those items by 4
4*2 = 8
4*3 = 12
4*5 = 20
4*7 = 28
Of those results, only 4*2 = 8 leads to a single digit answer.
This must mean that A = 8 and B = 2
Therefore the number is AB = 82.
Rachel multiplied each side of ≥x greater than or equal to 2 by 3. She wrote the result as ≤3 x less than or equal to 6 . Explain the error Rachel made.
Answer:
Rachel's error is in the inequality sign
Step-by-step explanation:
Given
[tex]x \geq 2[/tex]
Required
Determine the error in Rachel's workings
From the question, we understand that both sides of the inequality were multiplied by 3
i.e.
[tex]3 * x \geq 2 * 3[/tex]
This gives
[tex]3 x \geq 6[/tex]
Comparing this to Rachel's result: [tex]3 x \leq 6[/tex]
We can conclude that Rachel's error is in the inequality sign.
The sign of an inequality will only change is it is being multiplied or divided by a negative number; otherwise, the sign remains unchanged
