Answer:
1. 7/10, 2. 25, 3. 1/4 4. 4. 3/5, 5. A
Step-by-step explanation:
1. Make a fraction with the total number of cards at the bottom (60) and all the cards that are not green (aka yellow and blue) on top (42). Then simplify the fraction 42/60 by dividing both terms by 6 to get 7/10
2. For this one, first find how many students out of the first 80 liked basketball by subtracting the 60 students who liked other sports from 80. This gives you 20. Now you know that 20/80 students like basketball. Now simplify the fraction to get 1/4. Then find 1/4 of 100, because we know that 1/4 of students like basketball. 1/4 of 100 is 25.
3. This problem is exactly the same as number 1, except instead of adding all the other colors and putting them as a fraction over the total, just put the number of pink shirts over the total number of shirts to get 3/12. Then simplify it to 1/4, and that's your answer.
4. This is also similar to problems 1 and 3. Just put the number of heads coin tosses over the total and simplify it.
5. This one is very similar to all the problems so far. I will let you do this one on your own. Remember: The number of cases (rolls or colors or sports or cards etc.) that you want to find the probability for goes on top, and the total number of those things goes on the bottom. The bigger the fraction, the greater probability there is.
Note: Please only ask one question at a time on here instead of 5 at once. Since these problems are so similar, chances are, you could have figured them out on your own with a little help on one of them. You are more likely to get a quick answer if the answerer doesn't have to do as much work.

There are two answers to this.
1) The lines could be parallel if their y intercepts are different.
2) The lines are different forms of the same line.
For example

An online games club charges $5.75 for the first game download and $2 for each additional
download per month. Write a rule for describing the total monthly fees f as a function of
additional downloaus d. What are the fees for 15 game downloads in a month?
Answers
Answer:
a) The rule is;
f = 5.75 + 2d
b) f = $33.75
Step-by-step explanation:
Here, we want to write a rule
The rule is that we have a standard download fee of 5.75 for the first download, and then a download fee of $2 per download for the rest
We have this as;
f = 5.75 + 2(d)
f = 2d + 5.75
Now for 15 downloads;
first download is $5.75, remaking 14 is at a rate of $2 per one
Thus, we have the fee value as;
f = 5.75 + 2(14)
f = 5.75 + 28 = $33.75

Answers
Answer:
x = 23
Step-by-step explanation:
This entire angle makes up 90° b/c of the square box
65 + x + 2 = 90
x + 67 = 90
x = 23
Answer: x=23
Step-by-step explanation:
This is a right angle. A right angle is 90°. It already gives us 65°. So 90-65=25°. We now know (x+2) ° = 25°. 25-2=23.
We can prove this is correct by answering the problem they gave us. (23+2) is 25. 25+65=90° 90° is a right triangle which also happens to be the triangle they have shown us.

Rachel made 2 cups of trail mix containing all of the almonds, pumpkin seeds, and granola. How much trail mix did Ian make? How much more trail mix did Rachel make than Ian? Trail Mix Ingredients 4 cup almonds 4 cup pumpkin seeds 4cup coconut 4cup dried cranberries 1 4cup walnuts 1 cup granola4cup dried bananas
Answers
Answer:
The values written as Trail mix ingredients is not well written below is the trail mix ingredients
answer :
i) Ian made : 1 3/4 cups of trail mix
ii) Racheal made 1/4 more cup of trail mix
Step-by-step explanation:
Given that :
Trail Mix Ingredients
3 /4 cup almonds
1 /4 cup pumpkin seeds
2 /4 cup coconut
3 /4 cup dried cranberries
1 2 /4 cup walnuts
1 cup granola
2 /4 cup dried bananas
i) Ian used all of coconut , dried cranberries and dried Bananas
= 2/4 + 3/4 + 2/4
Amount of trail mix made = 7/4 = 1 3/4 cups
ii) Racheal made 2 cups of trail mix containing ; all almonds , pumpkin seeds and granola
= 3/4 + 1/4 + 1 = 2 cups of trail mix
Hence Racheal made ( 2 - 1 3/4 ) more trail mix than Ian
= 1/4 more cup of trail mix was made by Racheal
An inspector of school have wishes to distribute 84 balls and 180 bats equally among the number of boys . Find the greatest number recieving the gift in this way

3x = 15
x = 5
RS corresponds with LK so...
y + 10 = 27

De las 30 preguntas del examen de matematicas, por cada respuesta correcta se obtenian 5 puntos y por cada respuesta incorrecta, o pregunta no contestada,se perdian 2 puntos teodolindo obtuvo 94 puntos en este examen ¿cuantas respuestas correctas tuvo?
Answers
Answer:
Teodolindo obtuvo 22 respuestas correctas y 8 respuestas incorrectas o no contestadas.
Step-by-step explanation:
Un sistema de ecuaciones lineales, también conocido como sistema lineal de ecuaciones o simplemente sistema lineal, es un conjunto de ecuaciones lineales (es decir, un sistema de ecuaciones en donde cada ecuación es de primer grado), en el cual se relacionan dos o más incógnitas.
En los sistemas de ecuaciones, se debe buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en ambas ecuaciones.
En este caso se debe establecer un sistema de ecuaciones, donde las variables son:
x: cantidad de respuestas correctasy: cantidad de respuestas incorrectas o no contestadasSiendo 30 preguntas en el examen, se tiene la ecuación:
x + y= 30
Por cada respuesta correcta se obtenían 5 puntos y por cada respuesta incorrecta o pregunta no contestada, se perdían 2 puntos. Teodolindo obtuvo 94 puntos en este examen. Entonces se representa esta situación mediante la expresión:
5*x - 2*y= 94
Entonces el sistema de ecuaciones a resolver es:
[tex]\left \{ {{x+y=30} \atop {5*x-2*y=94}} \right.[/tex]
El método de sustitución consiste en despejar o aislar una de las incógnitas (por ejemplo, x ) y sustituir su expresión en la otra ecuación. De este modo, obtienes una ecuación de primer grado con la otra incógnita, y . Una vez resuelta, calculas el valor de x sustituyendo el valor de y calculado.
Entonces, despejando el valor de x de la primer expresión obtienes:
x= 30 -y
Reemplazando en la segunda ecuación obtienes:
5*(30 -y) - 2*y= 94
Resolviendo:
5*30 - 5*y - 2*y= 94
150 - 5*y - 2*y= 94
- 5*y - 2*y= 94 -150
-7*y= -56
y= (-56)÷(-7)
y= 8
Reemplazando el valor de y obtenido en la expresión x= 30 -y se obtiene:
x= 30 - 8
x=22

If the area of a rectangle is 64cm squared, how many different perimeters are possible when the dimensions are whole numbers
Answers
Answer:
2 different perimeters, 32 cm and 40 cm
Step-by-step explanation:
Given the area of a rectangle is 64 cm squared.
We know, Area of the rectangle is = length x breath
∴ 64 = 8 x 8
Hence the sides can be 8 cm by 8 cm.
So the perimeter of the rectangle is = 8 cm + 8 cm + 8 cm +8 cm
= 32 cm
Also, Area of the rectangle is = length x breath
∴ 64 = 16 x 4
So the perimeter of the rectangle is = 16 cm + 4 cm + 16 cm +4 cm
= 40 cm

= -r - 4n + 9y
4. 12y - 6x + 5y - 3n
