Nina is making pink candles to use as decorations on Valentine's Day. She melts red and white wax together and pours them into a heart-shaped mould. Then, she melts double the amount of red wax and double the amount of white wax together and pours them into a flower-shaped mould. Which candle is a lighter shade of pink?
Answer:
answer is neither, they are both the same shade.
Step-by-step explanation:
if she doubled the colors exactly then it wouldn't be any different. Also IXL told me I'm right :)
Answer:
Neither.
Step-by-step explanation:
Originally, she used the same amount. For the second one, she used double the same amount, but it was still the amount of red wax as of white wax. So, they both had the same amount, which means it is neither.

Find the measure of b.
Answer:
b = 55°
Step-by-step explanation:
The angle at the centre is twice the angle on the circle subtended by the same arc, then
a = 0.5 × 110° = 55°
Angles on the circumference subtended by the same arc are congruent, so
b = a = 55°

HELP PLSSS. Combine these radicals. - 12sqrt(12) - 2sqrt(3) O - 50sqrt(3); - 22sqrt(3); - 26sqrt(3); - 10sqrt(12)
The combined radical is: [tex]- 26\sqrt{3}[/tex]
The radical is given as:
[tex]- 12\sqrt{12} - 2\sqrt{3}[/tex]
We start by expressing 12 as 4 * 3
[tex]- 12\sqrt{12} - 2\sqrt{3} = - 12\sqrt{4* 3} - 2\sqrt{3}[/tex]
Split the radical
[tex]- 12\sqrt{12} - 2\sqrt{3} = - 12\sqrt{4}* \sqrt{3} - 2\sqrt{3}[/tex]
Take square root of 4
[tex]- 12\sqrt{12} - 2\sqrt{3} = - 12*2* \sqrt{3} - 2\sqrt{3}[/tex]
[tex]- 12\sqrt{12} - 2\sqrt{3} = - 24* \sqrt{3} - 2\sqrt{3}[/tex]
[tex]- 12\sqrt{12} - 2\sqrt{3} = - 24\sqrt{3} - 2\sqrt{3}[/tex]
Combine like terms
[tex]- 12\sqrt{12} - 2\sqrt{3} = - 26\sqrt{3}[/tex]
Hence, the combined radical is: [tex]- 26\sqrt{3}[/tex]

Un ingeniero civil a cargo de una obra contrata una cierta cantidad de obreros. Estima que, si le
pagara S/ 1.400 a cada uno de los obreros, le faltarían S/ 8.000, pero si le pagara S/ 1.200 a cada
uno, le sobrarían S/ 2.000. El número de obreros que contrató es
Al plantear un sistema de ecuaciones lineales, encontramos que el número de obreros que contrató el ingeniero civil fue 50.
Para encontrar el número de obreros que el ingeniero contrató debemos plantear un sistema de ecuaciones lineales de dos ecuaciones con dos incógnitas, tal como sigue:
[tex] M - 1400*x = -8000 [/tex] (1)
[tex] M - 1200*x = 2000 [/tex] (2)
En donde:
M: es la incógnita igual al monto de dinero del ingeniero
x: es la incógnita igual al número de obreros
De la ecuación (1) tenemos:
[tex] M = 1400*x - 8000 [/tex] (3)
Podemos encontrar el valor de x (número de obreros), introduciendo la ecuación (3) en la ec (2):
[tex] 1400*x - 8000 - 1200*x = 2000 [/tex]
[tex] 200*x = 10000 [/tex]
[tex] x = 50 [/tex]
El monto de dinero inicial del ingeniero sería entonces (ec 3):
[tex] M = 1400*50 - 8000 = 62000 [/tex]
Por lo tanto, el número de obreros que contrató el ingeniero es 50.

Step-by-step explanation:
On the median TW the distance from the vertex to the centroid is twice the distance from the centroid to the midpoint , then
YW = [tex]\frac{1}{2}[/tex] × TY = [tex]\frac{1}{2}[/tex] × 30 = 15

Answer:
The Answer is P = (-2.5 , 1 )
Step-by-step explanation:
Let, the point is P(x,y)
then, [tex]x=\frac{m_{1}x_{2}+ m_{2}x_{1}}{m_{1}+m_{2}}[/tex]
=>[tex]x=\frac{5*(-1)+ 3*(-5)}{5+3}[/tex]
∴[tex]x=-2.5[/tex]
Again, [tex]y=\frac{m_{1}y_{2}+ m_{2}y_{1}}{m_{1}+m_{2}}[/tex]
=>[tex]y=\frac{5*7+ 3*(-9)}{5+3}[/tex]
∴[tex]y=1[/tex]
Thus, P = (-2.5 , 1 )

Step-by-step explanation:
A father's age now is three times the age that his son was 4 years ago. In 12 years, the father will be twice as old as his son. find their ages now.
Answer:
In this problem, we can assign X to the son’s age and Y to the father’s.
We know that a father is 3 times as old as his son.
Therefore, we can create the equation 3X=Y.
We must now create a second equation from the remaining information, being “In 12 years he will be twice as old as his son”. We know we can add 12 years, along with including 2X in the equation.
The equation that we can gather from this second piece of information will be Y=2X+12. This is because the father’s age, in 12 year’s time, will be twice that of the child.
Now we have our two equations:
Y=3X
Y=2X+12
Because both equations are set equal to the age of the father, we can use the substitution method to solve in terms of the son’s age, as follows:
3X = 2X+12
Now we subtract 2X from each side to isolate the variable:
X=12
The son’s age is therefore 12 years old. Should we plug that age back into our first equation, we get Y=3(12) or Y=36.
The father’s present age is 36, while the son’s present age is 12.
The current age of the father is 12, while the age of the son is 0.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let say,
X = age of sun
Y = age of father
Given that
A father's age now is three times the age that his son was 4 years ago
So,
Y = 3(X -4)
Y = 3X - 12
And In 12 years, the father will be twice as old as his son
Y + 12 = 2( X + 12 )
Y = 2X - 12
From booth equation
X = 0 and Y = -12 which is not practical so Y =12

Hello,
[tex]Answer:\ 2.8 < x < 5.4[/tex]
Step-by-step explanation:
The simpliest is to use the triangular inequality:
in a triangle, a side must be inferior to the sum of the 2 others sides.
[tex]\left\{\begin{array}{ccc}4.1& < &x+1.3\\1.3&< &4.1+x\\x & < & 4.1+1.3\\\end{array}\right.\\\\\\\left\{\begin{array}{ccc}2.8& < &x\\1.3-4.1&< &x\ not\ used\\x & < & 5.4\\\end{array}\right.\\\\\\Finaly:\ 2.8 < x < 5.4[/tex]
Answer:
2.8 < x < 5.4
Step-by-step explanation:
Given 2 sides of a triangle then the third side is in the range
difference of 2 sides < x < sum of 2 sides , that is
4.1 - 1.3 < x < 4.1 + 1.3 , then
2.8 < x < 5.4

2π(a-r)(a+r)+4 = 52π
=> 2π(a²-r²)+4= 52π
=> (a²-r²)+4 = 52π/2π
=> (a²-r²)+4 = 26
=> (a²-r²)= 26-4
=> a²-r²= 22
[tex]\sf{}[/tex]
Answer:
=> a²-r²= 22
Step-by-step explanation:
2π(a-r)(a+r)+4 = 52
=> 2π(a²-r²)+4= 52π
=> (a²-r²)+4 = 52π/2π
=> (a²-r²)+4 = 26
=> (a²-r²)= 26-4
=> a²-r²= 22

a vegetable garden and a surrounding path are shaped like a square that together are 12 feet wide. the path is 1 foot wide. if one bag of gravel covers 9 square feet, how many bagas are needed to cover the path? round your answer to the nearest tenth.
Answer:
The answer to your question is: 8 bags of gravel
Step-by-step explanation:
Data
width = 11 ft
path = 2 ft
bag of gravel = 9 ft²
Area of a square garden with path= 11 x 11 = 121 ft²
Area of the square garden = 7 x 7 = 49 ft².
Area of the path = 121 - 49 = 72 ft²
# of bags = 72 / 9 = 8 bags
