hallar la medida del angulo "y"​

Answers

Answer: y = 11.25

Step-by-step explanation:

Mi espanol es terrible :l

Todos los angulos terminaran acompletando 90° grados

Entonces hagamos una ecuacion

3y + 4y + y = 90

8y = 90

Divide por 8

y = 11.25

Esta parte no es necesaria

Para ver si es verdad hagamos el math

3(11.25) = 33.75

4(11.25) = 45

y = 11.25

33.75 + 45 + 11.25 = 90

Can you help me on quadratic formulas?

Answers

Sure. Where is the question and I hope I can answer it

I take it as you want to learn about the formula.

The quadratic formula is a formula where you can solve x for any quadratic equation in form  ax^2+bx+c=0.

The formula is x= [tex]\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex].

The +- means + or - for the 2 solution in each equation.

*All above information is what you need to know about the quadratic formula and solve for answer, but I will go a step further in my answer to prove the quadratic formula always work.

[tex]0=ax^2+bx+c[/tex]

[tex]0=(ax+\frac{b}{2})^2-\frac{b^2}{4}+c[/tex] (This step is completing the square)

[tex](ax+\frac{b}{2})^2=\frac{b^2}{4}-c[/tex]

[tex](2ax+b)^2=b^2-4ac[/tex]

[tex]2ax+b=+or-\sqrt{b^2-4ac}[/tex]

[tex]2ax=-b+ or -\sqrt{b^2-4ac}[/tex]

[tex]x=\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex]

This is my way of proving this formula although there are many other ways to do it too, if there is any questions, feel free to ask me in the comment :-).

Six more than twice a number is greater than negative fourteen. Solve the inequality for the unknown number

Answers

Answer:

Step-by-step explanation:

2x+6 > -14

Subtract 6 from both sides

2x > -20

Divide both sides by 2

x > -10

The solution of the inequality 2x + 6 > - 14 will be greater than the negative 10.

What is the solution to the equation?

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Six more than twice a number is greater than negative fourteen.

Let x be the number. Then the equation will be

2x + 6 > - 14

Simplify the inequality, then the value of x will be

2x > - 20

x > - 10

The solution of the inequality 2x + 6 > - 14 will be greater than the negative 10.

Mary and Ardella are saving money for a trip. Mary started her savings with $20 and is now saving $12 each week. Ardella started her savings with $40 and is now saving $10 each week. After how many weeks will Mary and Ardella have saved the same amount of money To determine,

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements.

Let the number of weeks is x and total saving is y.
Now equation for Mary started her savings with $20 and is now saving $12 each week.
y = 12x +20 - - - (1)

The equation for Ardella, started her savings with $40 and is now saving $10 each week.
y = 10x + 40   - - - - (2)

Equating equation 1 and 2
12x +20 = 10x +40
12x -10x = 40 -20
2x = 20
x = 20/2
x = 10

Now put this x in equation 1
y = 12 * 10 + 20
y = 140

Thus, at the end of the 2 week both Mary and Ardella has an equal amount of saving i.e. $140.

How many tablespoons of blue paint should elena mix with 6 cups of white paint? How many batches would this make?

Answers

Answer:

there is no batches but there is gallons

Step-by-step explanation:

Answer:

18 tablespoons of blue paint; 3 batches

Step-by-step explanation:

For 1 batch of paint, she uses 2 cups of white paint and 6 tablespoons of blue paint.

She needs to mix blue paint using 6 cups of white paint.

6 cups is 3 times 2 cups, so she will be making 3 batches.

She also needs to use 3 times the amount of blue paint that she would use for 1 batch.

Since she uses 6 tablespoons of blue paint in 1 batch, she needs to use 3 times as much blue paint.

3 * 6 tablespoons = 18 tablespoons.
