You are going on a field trip and need to choose where to go, The zoo charges a $100 fee plus $10 per student. The museum charges $200 plus $5 per student. How many students have to go on the trip to make the museum a better deal
Answer:
21 kids have to go on the trip to make the museum a better deal
Step-by-step explanation:
Zoo: y=10x+100
Museum: y=5x+200
10x+100=5x+200
5x=100
x=20
When 20 kids go on trip the costs will be the same. Therefore, once 21 kids go the museum will be cheaper then the zoo as it is increasing at a rate of 5 dollars

Jill says that 23/1000 can be written as 0.23. Which explains whether or not Jill is correct? A. Yes, Jill is correct. The fraction 23/1,000 is equivalent to 0.23. B. No, Jill is not correct. The fraction is equivalent to 0.023. The decimal 0.23 is equivalent to. C. No. Jill is not correct. The fraction is equivalent to 0.0023. The decimal is 0.23 is equivalent to 23/100. D. No, Jill is not correct. The fraction 23/1,000 is equivalent to 2.3. The decimal 0.23 is equivalent to 23/100. D. No, Jill is not correct. The fraction 23/1,000 is equivalent to 2.3. The decimal 0.23 is equivalent to 23/100.
Answer:
B. No, Jill is not correct, the fraction is equivalent to 0.023.
Step-by-step explanation:
The given fraction is [tex]\frac{23}{1000}[/tex]
Observe that in the denominator there is 1000, which has three zeros after 1.
In changing the given fraction to decimal, there must be 3 significant digits after the decimal.
According to this option (b) is correct.
Moreover, when 23 is divided by 1000, we have
[tex]\frac{23}{1000}=0.023[/tex]
But Jill says that 23/1000 can be written as 0.23, so, Jill is not correct.
Hence option (b) is correct,

Which function has a greater degree?
Answer:
I think it's either B or C because A and D don't make sense in my opinion.
Step-by-step explanation:
The degree of the p (x) is greater because r (x) is quadratic.
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The function p (x) is,
⇒ p (x) = 4x³ - 2x² + 15
And, The function of r (x) is find by table.
Here, By the given table;
The degree of r (x) is 2, because it is quadratic.
And, The degree of p (x) is 3.
Thus, We can conclude that;
The degree of the p (x) is greater because r (x) is quadratic.

Imaginá que tenés 125 dados cúbicos del mismo tamaño ¿Cuantos dados de altura tiene el cubo de mayor tamaño que podés armar apilando de manera conveniente todos ellos? Mostrá cómo lo pensaste Si quisieras formar un "cuadrado" con la mayor cantidad de cubos posibles, ¿cuántos deberías poner sobre cada lado? ¿Te quedarían cubos sueltos? ¿Cuántos? Mostrá cómo razonás
Answer:
(i) Debemos apilar 5 dados para construir el cubo de mayor tamaño.
(ii) Se necesita 121 dados cuadrados para formar el cuadrado con la mayor cantidad de dados posibles, quedando 4 dados sobrantes.
Step-by-step explanation:
(i) Sabemos por la Geometría Euclídea del Espacio que un cubo es un sólido regular con 6 caras cuadradas y longitudes iguales. Cada dado tiene un volumen de 1 dado cúbico y 125 dados dan un volumen total de 125 dados cúbicos.
El volumen de un cubo está dado por la siguiente fórmula:
[tex]V = L^{3}[/tex]
Donde:
[tex]L[/tex] - Longitud de la arista, medida en dados.
[tex]V[/tex] - Volumen del cubo, medido en dados cúbicos.
Ahora, necesitamos despejar la longitud de la arista para calcular la altura máxima posible:
[tex]L = \sqrt[3]{V}[/tex]
Dado que [tex]V = 125\,dados^{3}[/tex], encontramos que la altura del cubo de mayor tamaño sería:
[tex]L =\sqrt[3]{125\,dados^{3}}[/tex]
[tex]L = 5\,dados[/tex]
Debemos apilar 5 dados para construir el cubo de mayor tamaño.
(ii) El área cuadrada formada por cubos está determinada por la siguiente fórmula:
[tex]A = L^{2}[/tex]
Donde:
[tex]L[/tex] - Longitud de arista, medida en dados.
[tex]A[/tex] - Área, medida en dados cuadrados.
Puesto que la longitud de arista se basa en un conjunto discreto, esto es, el número de dados disponibles, debemos encontrar el valor máximo de [tex]L[/tex] tal que no supere 125 y de un área entera. Es decir:
[tex]L \leq 125\,dados[/tex]
Si cada cubo tiene un área de 1 dado cuadrado, entonces un cuadrado conformado por 125 dados tiene un área total de 125 dados cuadrados. Entonces:
[tex]L^{2}< 125\,dados^{2}[/tex]
Esto nos lleva a decir que:
[tex]L < 11.180\,dados[/tex]
Entonces, la longitud máxima del cuadrado con la mayor cantidad de cubos posible es de 11 dados. El número total requerido de cubos es el cuadrado de esa cifra, es decir:
[tex]n = (11\,dados)^{2}[/tex]
[tex]n = 121\,dados[/tex]
Se necesita 121 dados cuadrados para formar el cuadrado con la mayor cantidad de dados posibles, quedando 4 dados sobrantes.
Lucy runs at an average speed of 3.5 miles per hour. John runs 2 miles per hour faster than Lucy. How far will John run (r) he runs x number of hours?
Answer:
It is 5.5 miles/hour if you are trying to figure out how fast john runs.
Step-by-step explanation:
if john run 2 mile/hour faster than lucy, you just have to add how fast lucy is running by 2. This will equal john's miles/hour. now you times 5.5 by how many hours he runs.

Jebrel borrowed $7000 from his friend. He saves $110 each month to pay him back.
Answer:
What is the question? This is just a statement
Step-by-step explanation:
William must have at least $250 this month. He has already earned $100, how much more
should he earn this month? Use m to represent the amount of money he still needs to eam.
Subtract the amount he has from the amount he needs:
M = 250 -100
M = 150
He needs to earn$150 more
Answer:250-100=150
Step-by-step explanation:
9) Carla's credit card statement showed that she owed $350. She
Thade a payment of $200, then she charged $23 for gasoline She
returned a sweater she had charged earlier for a refund of $35
Then she charged $15 at the bookstore. What is her new balance?
35
Answer:
the answer is -153
Step-by-step explanation:
350-200(she paid off 200$)=150
150+23(she charged her account 23$)=173
173-35(she paid off 35$)=138
138+15(she charged her account 15$)=135
her new balance is -153$ because that is how much she has left to pay off before she reaches 0 then she can gain credit.

Solve 3kx + 24 = 9 kx for x.
Answer:
Step-by-step explanation:
3kx + 24 = 9kx
First subtract 3kx to both sides.
24 = 9kx - 3kx
24 = 6kx
Divide both sides by 6
24/6 = kx
4 = kx
Divide both sides by k.
4/k = x
