Quadrilateral Practice Test, I’ll give brainliest to the correct answer with explanation

Mathematics
1 answer:
pshichka [43]3 years ago

Answer:

120 Degrees

Step-by-step explanation:

Angle T and R are vertical angles meaning they are equal so combine the equations: 31x - 4 = 29x + 4, then solve using inverse operations

subtract 31x from both sides to get -4 = -2x + 4

Then subtract 4 from both sides to get -8 = -2x, now that we have isolated the variable we have to divide by -2 on both sides getting us x = 4, then plug in the four to the equation for angle R getting you 29 times 4 which equals 116 + 4 = 120

A square piece of fabric has an area of (9x2 + 24x + 16) square inches. The length of each side of the fabric is (cx + d) in., w
horrorfan [7]
If the area of the square is 9x^+24x+16, then the side length wouldd be the square root of that. That would be 3x+4. The perimeter would be 4 times that so the perimeter is 4(3x+4) = 12x+16

Hope that helped

Maria necesita un par de zapatos de tacon para un evento de gala y ya vio tres pares que le gustaron mucho cada uno cuesta $500,
Art [367]

Answer:

Mária debe trabajar mínimo 9 horas si quisiera tener la cantidad para pagar cualquiera de los pares de zapatos.

Step-by-step explanation:

Tenemos que calcular la cantidad de horas que tiene que trabajar María para alcanzar la cantidad de dinero necesaria para comprar alguno de los pares. La cantidad de dinero que Mária gana por trabajar x horas es 50.50*x. La cantidad total de dinero que tiene María está dada por 200+50.50*x (se le suma la cantidad que tiene ahorrada). Luego, basta con que esta cantidad sea mayor o igual al precio de cada par de zapatos.

Para hacerlo de manera más general, considerando unos zapatos que cuestan y, tenemos la siguiente inecuación

200+50.5x \geq y

Restando 200 a ambos lados y dividiendo por 50.5 obtenemos que

x \geq \frac{y-200}{50.5}

Basta reemplazar y por el valor de cada par de zapatos, para obtener su x correspondiente.

Si y = 500, entonces x \geq 5.94. Es decir, debe trabajar mínimo 6 horas.

Si y = 580 entoncesx \geq 7.52. Es decir, debe trabajar mínimo 8 horas

si y = 620 entoncesx\geq 8.31. Es decir, debe trabajar mínimo 9 horas.

Es decir que si quisiera tener la cantidad para pagar cualquiera de los pares, debe trabajar mínimo 9 horas.

Select the best equation needed to solve for x; then solve for x:
Lena [83]

Answer:

x=28 or C

Step-by-step explanation:

The graph shows a right angle which is 90 degrees

This means that the two angles seperated by line C added together will get 90 degrees.

That means the formula will be 2x+1+33=90

With that shown we can get rid of A and B

Next step is to add 33 and 1 together

This gives us 2x+34=90

Then we will move 34 to the other side by subtracting giving us 2x=90-34

Then we will subtract 90-34 which will get us 56

The equation is now 2x=56

The last step is to devide 2 from each side

This lets us get the answer x=28

Hope this helps!
