Answer:
La fracción de bombones que se comieron entre los dos es [tex]\frac{7}{10}[/tex]
La caja tenía 40 bombones.
Step-by-step explanation:
Sabes que Andrés se comió 1/5 de los bombones de una caja y Ana 1/2 de la misma. Para conocer la fracción de bombones que se comieron entre ambos, debes sumar las fracciones que comieron cada uno:
[tex]\frac{1}{5} +\frac{1}{2}[/tex]
Para hacer suma de fracciones con distinto denominador, lo primero que hay que hacer es determinar un denominador común. Para eso debes calcular el mínimo común múltiplo (mcm) entre los denominadores.
En este caso, el mcm entre 5 y 2 es 10.
Ahora tienes que multiplicar cada numerador por el número que hayas multiplicado el denominador. Para ello, dividís el m.c.m entre el denominador inicial y el resultado se multiplica por el numerador de esa fracción:
10÷5= 2 ⇒ 2*1= 2 Por lo tanto, 2 es el numerador de la primera fracción.10÷2= 5 ⇒ 5*1= 5 Por lo tanto, 5 es el numerador de la segunda fracción.Entonces:
[tex]\frac{1}{5} +\frac{1}{2}=\frac{2}{10} +\frac{5}{10}[/tex]
Ahora simplemente sumas los denominadores:
[tex]\frac{1}{5} +\frac{1}{2}=\frac{2}{10} +\frac{5}{10}=\frac{7}{10}[/tex]
La fracción de bombones que se comieron entre los dos es [tex]\frac{7}{10}[/tex]
Sabes que quedaron 12 bombones en la caja. Representando 1 la cantidad total de bombones, y si se comieron 7/10 de la caja, entonces quedaron:
[tex]1-\frac{7}{10}[/tex]
Restando de manera similar al procedimiento usado para la suma se obtiene:
[tex]1-\frac{7}{10}=\frac{3}{10}[/tex]
Finalmente podes aplicar la siguiente regla de tres: si 3/10 representa los 12 bombones que quedaron en la caja, entonces en 1 (que representa la cantidad total de bombones) cuantos bombones hay?
[tex]cantidad total de bombones=\frac{1*12}{\frac{3}{10} }[/tex]
cantidad total de bombones=40
La caja tenía 40 bombones.

Answer:
C. 43.96
Step-by-step explanation:
2 × 3.14 × 7
Equation is 2×pi×radius
Answer: The answer is B
Step-by-step explanation:
The formula is 2πr. 2 * 3.14 * 7 6.28 *7 = 43.96The scale of a map says that 3 cm represents 8 km.
What distance on the map (in centimeters) represents an actual distance of 20 kilometers?
What is the actual number of kilometers that is represented by 12 centimeters on the map?
PLEASE HELP ME ASAP I WILL MAKE YOU BRAINIEST!!
Answer:
Step-by-step explanation:
Problem 1
Set Up the Proportion
3 cm / 8 km = x / 20 km Cross multiply
3*20 = 8x Combine the left
60 = 8x Divide by 8
60/8 = x
7 4/8 = x
7 1/2 km = x
7.5 km = x
Problem 2
3 cm / 8km = 12 cm / x Cross multiply
3x = 12 * 8 Combine the right
3x = 96 Divide by 3
3x/3 = 96/3
x = 32 km
What is the slope of the line that passes through (2,5) and (6, 7)?
Answer:
1/2
Step-by-step explanation:
Slope is the change in y over the change in x so:
(7 -5) /(6-2) = (2)/(4) = 1/2
(-12,8), (6,2)
What is the point-slope form of the equation of the line?
Answer:
x-
Step-by-step explanation:
A square and a rectangle have the same area. The length of the rectangle is twelve more than twice times the side of the square. The width of the rectangle is eight less than the side of the square. Let x be the length of the side of the square. Using the information above, what is the value of x?
Answer:
[tex]x = 12[/tex]
Step-by-step explanation:
Given
Shapes: Square and Rectangle
Square:
[tex]Length = x[/tex]
Rectangle:
[tex]Length = 12 + 2x[/tex]
[tex]Width = x- 8[/tex]
Required
Find x
First, we calculate the area of the square.
[tex]Area = x * x[/tex]
[tex]Area = x^2[/tex]
Next, we calculate the area of the rectangle
[tex]Area = (12 + 2x) * (x - 8)[/tex]
[tex]Area = 12x -96 + 2x^2 - 16x[/tex]
[tex]Area = 2x^2 - 16x + 12x -96[/tex]
[tex]Area = 2x^2 -4x -96[/tex]
Since both areas are equal, we have:
[tex]x^2 = 2x^2 -4x -96[/tex]
Equate to 0
[tex]2x^2 -x^2 -4x -96= 0[/tex]
[tex]x^2 -4x -96= 0[/tex]
Expand:
[tex]x^2 - 12x + 8x -96 = 0[/tex]
[tex]x(x - 12) + 8(x - 12) = 0[/tex]
[tex](x + 8)(x - 12) = 0[/tex]
[tex]x + 8 = 0[/tex] or [tex]x - 12 = 0[/tex]
[tex]x = -8[/tex] or [tex]x = 12[/tex]
But x can't be negative.
Hence:
[tex]x = 12[/tex]

recipe for two dozen cookies calls for 234cups of sugar. How much sugar is needed to make one dozen cookies? A 38cupsover33, cups B 138cupsove1r, cups C 134cupsover34, cups D 512cups5 and 1 half cup
Answer:
117 cups
Step-by-step explanation:
two dozen cookies calls for 234cups of sugar
2 dozen cookies = 234 cups of sugar
How much sugar is needed to make one dozen cookies?
Let x = cups of sugar needed
1 dozen cookies = x cups of sugar
2 dozen cookies : 234 cups of sugar = 1 dozen cookies : x cups of sugar
2 : 234 = 1 : x
2 / 234 = 1 / x
Cross product
2*x = 234 * 1
2x = 234
x = 234 / 2
= 117 cups

An amusement park charges a $12 parking fee plus 25 per person. What is the total cost for 32 people?
Answer:
The total amount for 32 people is 15.36
Step-by-step explanation:
we know that for 25 people is $12 so we need to find how much it would be for one person. you would need to divide $12 / 25. from this you would get 0.48, so for one person it's 48 cents. next you're going to subtract 25 from 32, this leaves you with seven people who aren't in a group of 25. you then multiply 7 × this equals to 3.36, add 3.36 to $12 and you'll get your total 15.36.

Graph a line that contains the point (3,-6) and has a slope of
2
khan academy i need it!!
Answer:
[tex]\boxed {\boxed {\sf y= 2x-12}}[/tex]
Step-by-step explanation:
We are given a slope and a point, so we can use the point-slope equation.
[tex]y-y_1=m(x-x_1)[/tex]
where m is the slope and (x₁, y₁) is the point.
The slope is 2 and the point is (3,-6).
[tex]m= 2\\x_1=3 \\y_1=-6[/tex]
Substitute the values into the formula.
[tex]y--6=2(x-3)[/tex]
[tex]y+6=2(x-3)[/tex]
Distribute the 2 on the right side of the equation.
[tex]y+6=(2*x)+(2*-3)[/tex]
[tex]y+6=2x-6[/tex]
We want to get the line into the form: y=mx+b. We have to isolate y on one side of the equation. 6 is being added to y. The inverse of addition is subtraction; subtract 6 from both sides of the equation.
[tex]y+6-6=2x-6-6[/tex]
[tex]y=2x-6-6[/tex]
[tex]y=2x-12[/tex]
The line is y=2x-12 (slope=2 and y-intercept=-12)
