Al principio Eduardo y Adrián tenían el mismo número de dulces. Eduardo le dio a Adrián la mitad de los dulces que tenía. Después, Adrián le dio a Eduardo la mitad de los dulces que tenía él en ese momento, así que a Adrián le quedaron 12 dulces. ¿Cuántos dulces tenía Eduardo al final? *
Answer:
Al final, Eduardo tenía 20 dulces.
Step-by-step explanation:
Dado que al principio Eduardo y Adrián tenían el mismo número de dulces, y Eduardo le dio a Adrián la mitad de los dulces que tenía, y después, Adrián le dio a Eduardo la mitad de los dulces que tenía él en ese momento, así que a Adrián le quedaron 12 dulces, para determinar cuántos dulces tenía Eduardo al final se debe realizar el siguiente cálculo:
Eduardo 1X = Adrián 1X
Eduardo 0.5X = Adrián 1.5X
Eduardo 1.25X = Adrián 0.75X
0.75 X = 12
X = 12 / 0.75
X = 16
1.25 X = 16 x 1.25 = 20
Así, al final, Eduardo tenía 20 dulces.
A waffle cone has a volume of 31.254 cubic centimeters and a radius of
2.5 centimeters. What is the approximate height of the cone?
Answer:
4.78 cm
Step-by-step explanation:
The formula for the volume of a cone of radius r and height h is
V = (1/3)πr²h. Here, V = 31.254 cm³ and r = 2.5 cm.
We begin by solving V = (1/3)πr²h for the unknown height, h:
31.254 cm³ 3(31.254 cm³) 93.762 cm³
h = ------------------------ = -------------------------- = -------------------- ≈ 4.78 cm
(1/3)πr² π(2.5 cm)² 19.635 cm²

What is the
approximate value of x?
Answer:
There is no work shown
Step-by-step explanation:
So you find the derivative root X you'll get 1 over 2 X to the power 1 by 2 and exactly after that you write the formula for the approximation.
which is grater .856 or .8561
Answer: .8561
Step-by-step explanation: If you make them the same number by adding a 0 to .856 it would look like
.8561
.8560
Answer:
I think it would be .856
Step-by-step explanation:
0.5 is greater than 0.05. There are many ways to deduce this:
The more the # of zeroes after the decimal point the smaller the number is. Suppose there are x number of extra zeroes after the decimal point in number a than number b. Then, b is 10^x times larger than a.
Multiply both numbers by 100. we can see 0.5*100 (=50) > 0.05*100 (=5)
Fractionalize both numbers, we get 0.5=(5/10) but 0.05=(5/100). This makes 0.05<0.5

The function y=f(x) is graphed below. What is the average rate of change of the function f(x) on the interval 7≤x≤8?
Answer:
-2Step-by-step explanation:
We see on the graph:
f(7) = 2f(8) = 0Average rate of change:
(f(8) - f(7))/(8 - 7) =(0 - 2)/1 = -2Triangle LMN has vertices at L(0, 0), M(0,4), and N(-3,0). The triangle will be rotated 270° counterclockwise about the origin. What will

Solve the system of equations -3x+7y=-18 and 4x-4y=8 by combining the equations.
Explaining Is Required
Answer:
[tex]\huge \colorbox{red}{(x,y)=(-1,-3)}[/tex]
Step-by-step explanation:
multiply first equation by 4 and second by 3 respectively:
[tex] \begin{cases} \displaystyle - 12x + 28y = - 72 \\ \: \: \displaystyle \: 12x - 12y = 24 \end{cases}[/tex]
combine the equations:
[tex] \underline{ \begin{cases} \displaystyle - 12x + 28y = - 72 \\ \: \: \displaystyle \: 12x - 12y = 24 \end{cases}} \\ \displaystyle16y = - 48[/tex]
divide both sides by -48:
[tex] \displaystyle \: \frac{16y}{16} = \frac{ - 48}{16} \\ y = - 3[/tex]
substitute the value of y to the second equation
[tex] \displaystyle \: 4x - 4. - 3 = 8[/tex]
simplify multiplication:
[tex] \displaystyle \: 4x + 12 = 8[/tex]
cancel 12 from both sides:
[tex] \displaystyle \: 4x = - 4[/tex]
divide both sides by 4
[tex] \displaystyle \: \frac{4x}{4} = \frac{ - 4}{4} \\ x = - 1[/tex]
therefore our solution is
[tex]\displaystyle (x,y)=(-1,-3)[/tex]
Answer:
Solution given:
-3x+7y=-18
3x-7y=18.................[1]
4x-4y=8
4(x-y)=8
x-y=[tex] \frac{8}{2} [/tex]
x-y=2..........….........[2]
multiplying equation 2 by 3 and subracting equation 1 and 2,we get
[tex]3x-7y - 3x + 3y = 18 - 6[/tex]
-4y=12
y=[tex] \frac{12}{ - 4} [/tex]=-3
substituting value of y in equation 2,we get
x-(-3)=2
x=2-3
x=-1
:.
x=-1
y=-3
Solve the simultaneous equation:
2x+3y=13
X+2y=9
Answer:
2x + 3y = 13
4x - y = -2
In the second equation, subtract 4x from both sides.
-y = -2 - 4x
Divide both sides by -1.
y = 2 + 4x
Put this into the first equation in place of y.
2x + 3(2 + 4x) = 13
Multiply everything in the parenthesis by 3.
2x + 6 + 12x = 13
Combine like terms.
14x + 6 = 13
Subtract 6 from both sides.
14x = 7
Divide 14 on both sides.
x = 7 / 14
x = 0.5
Put this into the second equation in place of x.
4(0.5) - y = -2
2 - y = -2
Subtract 2 from both sides.
-y = -4
Divide both sides by -1.
y = 4
So x = 0.5 and y = 4.

A mad scientist is trying to turn herself into a superhero in her lab at point B. There is an explosion and
anyone within a radius of 8 miles from the lab turns into a superhero. Unfortunately, anyone between 8 and
10 miles from the blast turns into an evil villain. If the population is evenly distributed over the total area,
are there more evil villains or more superheroes?
Answer:
superheros
Step-by-step explanation:
area of the 8 milrs- 201.06sq miles
area of 10 miles- 314.16sq miles
subtract the 210.06 from 314.16, 104.1
so, 210.06 square miles of heros, 104.1 square miles of villians
