Answer:

DE is 4 units long.

Step-by-step explanation:

These are the 30-60-90 triangle side relationships:

We 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.

Answer:

-45

Step-by-step explanation:

Answer:

7 is isosceles so x= 55 bc the other angle is. 8 is isosceles so x= 68 and 9 is right angle all angles in a triangle add up to 180 so 180-90 /2 = 45 so x=45

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.

2. (Solving)

4.9:

15.27%:

Therefore, the answers are 490% and .1527.

Answer: 490% and .1527

Step-by-step explanation:

Decimal to percentage: move decimal place 2 spaces to the left

Percentage to decimal: move decimal 2 space to the right

Answer:

the smaller number is 27.

Step-by-step explanation:

set two numbers are a and b

one number is less that twice of a number:

let's say a is 5 less than twice of b

so we have : a=2b-5

sum of the two numbers is 76: we have a+b=76

then we set up the system of equation[tex]\left \{ {{a=2b-5} \atop {a+b=76}} \right.[/tex]

substitude a = 2b - 5 into the second equation

we have,

2b - 5 + b = 76

3b - 5 = 76

3b = 81

b = 27

Since a + b = 76 so a = 49

Answer:

216 boxes

Step-by-step explanation:

you can see by the highlighted point that in 5 hours 60 boxes are shipped. that means 12 boxes per hour (60/5=12)

When you know this just multiply the hours by 12 and you get 12*18=216

Let's solve for x.

3x+y+z=6

Step 1: Add -y to both sides.

3x+y+z+−y=6+−y

3x+z=−y+6

Step 2: Add -z to both sides.

3x+z+−z=−y+6+−z

3x=−y−z+6

Step 3: Divide both sides by 3.

3x3

=−y−z+6/3

x=−1/3y+−1/3z+2

2x - 7 = 4

Step-by-step explanation:

Answer:

2x-7=4

Step-by-step explanation:

seven less is a number minus 7 so __ - 7

a product of a number and 2 is multiplication so 2 * x or 2x therefore 2x-7

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]

Answer:

$700

Step-by-step explanation:

  First, multiply 5,000 times 7:

  5,000 × 7 = 35,000

  Since 7% is 0.07, move the decimal place in 35,000 two times:

  35,000.

The lights which were on was 48%.

A percentage is a number or ratio that can be expressed as a fraction of 100.

Given that there were 72 lights on, and 78 lights turned off.

We need to find the percent of the lights turned on.

So, percentage of something =

= number of thing / total number of the thing x 100%

Here, the number of thing = light on = 72

Total = 72 + 78 = 150

So, the percent of light on = 72 / 150 x 100% = 0.48 x 100%

= 48%

Hence the lights which were on was 48%.

Answer:

Step-by-step explanation:

Two angles are supplementary, that means their sum is equal to 180 degrees

3e - 4 + e + 8 = 180 add like terms

4e + 4 = 180 subtract 4 from both sides

4e = 176 divide both sides by 4

e = 44

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:

Entonces, 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.

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.
