Answer:
DE is 4 units long.
Step-by-step explanation:
These are the 30-60-90 triangle side relationships:
Short leg × 2 = hypotenuseShort leg × √3 = long legLong leg ÷ √3 = short legHypotenuse ÷ 2 = short legWe are given the long leg and need to find the short leg. As seen above, the relation ship between those sides is:
[tex]S*\sqrt{3}=L[/tex]
or:
[tex]L \div \sqrt3 =S[/tex]
Given the long leg, divide it by √3 to find the short leg.
[tex]4\sqrt3 \div \sqrt3 = 4[/tex]
The short leg is 4 units long.

Can someone help with this ? Will mark brainlest
Answer:
x = 24
Step-by-step explanation:
According to the vertical angles rule, x - 17 = 180 - (7x + 5) or x - 17 = 180 - 7x -5 and when we solve for x we get x = 24
The function h (d) = 2d + 4.3 relates the height (h) of the water in a fountain in feet to the diameter (d) of the pipe carrying the water in inches. Find h (1.5) and interpret your solution in the context of the problem find the value of d when h (d) = 10.3 and interpret your solution in the context of the problem
Answer:
h(1.5) = 7.3 ft
h(10.3) = 24.9 ft
Step-by-step explanation:
Given the function h(d) = 2d + 4.3,
where:
h = height of the water in a fountain (in feet)
d = diameter of the pipe carrying the water (in inches)
h(1.5)Substitute the input value of d = 1.5, into the function:
h(1.5) = 2(1.5) + 4.3
h(1.5) = 3 + 4.3
h(1.5) = 7 feet
The height of the water in a fountain is 7 feet when the diameter of the pipe is 1.5 inches.
h(10.3)Substitute the input value of d = 10.3, into the function:
h(10.3) = 2(10.3) + 4.3
h(10.3) = 20.6 + 4.3
h(10.3) = 24.9 feet
The height of the water in a fountain is 24.9 feet when the diameter of the pipe is 10.3 inches.
Context of the solutions to h(1.5) and h(10.3):The solutions to both functions show the relationship between the diameter of the pipe to the height of the water in a fountain. The height of the water in fountain increases relative to the diameter of the pipe. In other words, as the diameter or the size of the pipe increases or widens, the height of the water in a fountain also increases.
Which of the following values are solutions to the inequality
-10 + 3.x > -4?
I. 8
II. 2
III. - 6
To solve x, you need to isolate the variable with the following steps.
-10 + 3x > -4
3x > 6 Add 10 to both sides.
x > 2
The solution is x > 2, or answer II and III.
In the triangle below, which equation can be used to solve for x?
Answer:
4th option
Step-by-step explanation:
We require to find the 3rd angle in the triangle, that is
third angle = 180° - (75 + 50)° = 180° - 125° = 55°
Using the Sine rule in the triangle
[tex]\frac{x}{sin75}[/tex] = [tex]\frac{13}{sin55}[/tex] ( cross- multiply )
x × sin55° = 13 × sin75° ( divide both sides by sin55° )
x = [tex]\frac{13sin75}{sin55}[/tex]

Hello, your
Step-by-step explanation:
For this particular problem (with units in mind), the formula for arc length is
Arc length
=
2
π
r
⋅
(
x
360
∘
)
,
Where
x
is the central angle measure and
r
is the radius of the circle.
You don't really have to work too hard to remember this formula. The arc length formula is easy to remember because it is just the circumference of the circle times the central angle over
360
∘
.
Anyway, let's continue with the problem. We are given that the central angle is
60
∘
, and that
r
, our radius, is
9
feet. So, let's plug that into our equation to find the arc length, in feet:
Arc length
=
2
π
r
⋅
(
x
360
∘
)
Arc length
=
2
π
(
9
)
⋅
(
60
∘
360
∘
)
Now, you might be tempted to plug this in your calculator, but let's simplify it a little bit more.
Arc length
=
2
π
(
9
)
⋅
(
60
∘
360
∘
)
Arc length
=
18
π
⋅
(
1
6
)
Arc length
=
3
π
feet
So, if you wanted an exact answer, it would be that the arc length is
3
π
feet
. If you wanted an approximate answer, then you can type
3
times
π
in your calculator to get a value of about
9.425
feet
as you alternative answer.

Drag each label to the correct location on the image. Identify which equations have one solution, infinitely many solutions, or no solution.
Answer:
"1/2y+3.2y=20" One solution
"15/2+2z-1/4=4z+29/4-2z" Infinitely many solutions
"3z+2.5=3.2+3z" No solution
"1.1+3.4x+2=3.1+3/4x" infinitely many solutions
"4.5r=3.2+4.5r" No solution
"2x+4=3x+1/2" one solution
To determine the number of solutions for each equation in the given image, we need to analyze each equation separately. Let's go through each equation and identify whether it has one solution, infinitely many solutions, or no solution.
Equation 1: 3x - 2y = 6 Equation 2: 6x - 4y = 12 Equation 3: 2x - y = 3
To find the solutions, we can use the method of substitution or elimination.
First, let's consider Equation 1: 3x - 2y = 6
If we rearrange this equation to solve for y, we get: y = (3x - 6) / 2
Now, let's examine Equation 2: 6x - 4y = 12
If we rearrange this equation to solve for y, we get: y = (6x - 12) / 4 y = (3x - 6) / 2
Comparing the two equations for y, we can see that they are the same. This means that Equation 1 and Equation 2 represent the same line.
In other words, they have infinitely many solutions.
Any point on the line formed by these equations satisfies both equations simultaneously.
Moving on to Equation 3: 2x - y = 3 If we rearrange this equation to solve for y, we get: y = 2x - 3
This equation represents a line with a specific slope and y-intercept. Since it is different from the line represented by Equation 1 and Equation 2, we can conclude that Equation 3 has one solution.
This means that there is a unique point of intersection between Equation 3 and the other two equations.
In summary: - Equation 1 and Equation 2 have infinitely many solutions since they represent the same line.
- Equation 3 has one solution since it intersects the other two equations at a unique point.

Answer:
4.9 = 490%
15.27% = .1527
Step-by-step explanation:
1. To convert a decimal into a percentage, you multiply the decimal by 100.
For example, if we convert the number 1.01 into a percentage by multiplying it by 100, we get 101%. When converting from percentage to decimal, you divide by 100.2. (Solving)

How to solve 3x+12=2x
Answer: x=-12
Step-by-step explanation:
subtract 12 from both sides
3x=2x-12
subtract 2x from both sides
x=-12
Subtract 12 from both sides of the equation:
3x + 12 = 2x
3x + 12 - 12 = 2x - 12
Simplify:
3x = 2x - 12
Subtract 2x from both sides of the equation:
3x = 2x - 12
3x-2x = 2x - 12-2x
Simplify:
combine like terms --> multiply by 1 --> combine like terms
x = -12 <-- ANSWER

Benjamín le dijo a Gustavo el doble del dinero que tengo más la mitad de esa cantidad es 200 pesos ¿con cuánto dinero cuenta Benjamín?
Considerando la definición de una ecuación, Benjamín cuenta con una cantidad de dinero de 66.67 pesos.
Una ecuación es la igualdad existente entre dos expresiones algebraicas conectadas a través del signo de igualdad en la que figuran uno o varios valores desconocidos, llamadas incógnitas, además de ciertos datos conocidos.
Los miembros de una ecuación son cada una de las expresiones que aparecen a ambos lados del signo igual.
En este caso, "el doble del dinero que tengo más la mitad de esa cantidad es 200 pesos" puede ser expresado mediante una ecuación, donde consideras que "x" es la incógnita, que representa la cantidad de dinero que tiene Benjamín.
Teniendo en cuenta que la mitad de un número se calcula dividiendo el número por 2, mientras que el doble de un número se calcula multiplicando el número por 2, entonces:
El doble del dinero que Benjamín tiene es: 2xLa mitad de esa cantidad es: (2x)÷2= xEntonces, la ecuación queda expresada como:
2x + x= 200
Resolviendo:
3x= 200
x=200÷3
x= 66.67
Finalmente, Benjamín cuenta con una cantidad de dinero de 66.67 pesos.
