The perimeter of an equilateral triangle is 15 inches more than the perimeter of a square, and the side of the triangle is 7 inches longer than the side of the square. What is the side of the triangle?

Answers

Answer 1

Answer:

13 inches

Step-by-step explanation:

in an equilateral triangle all sides had we the same length.

so, the perimeter is simply 3×one triangle side.

and the perimeter of the square is 4×one square side.

x = triangle side length

y = square side length

3x = 4y + 15

x = y + 7

we use the second equation as substitution in the first equation.

3(y + 7) = 4y + 15

3y +21 = 4y + 15

6 = y

x = y + 7 = 6 + 7 = 13 inches

Margarita entrena tres semanas para participar en un maratón. En la segunda semana recorre 1 km más que en la primera y en la tercera semana, corre el doble de km que los corridos en la segunda, ¿cuál es la representación algebraica simplificada de los kilómetros recorridos durante el entrenamiento?

Answers

Queremos encontrar una expresión algebraica que representa la situación dada.

Encontraremos que está es: 4*D + 3

Lo primero que debemos hacer es definir la variable.

Definamos D como la distancia que Margarita recorre en la primer semana.

En la segunda semana, Margarita recorre un kilometro más que en la primera, entonces en la segunda semana Margarita recorre:

D + 1km

En la tercera semana, Margarita recorre el dolbe de km recorridos en la segunda.

En la segunda ella recorrio D + 1km, y el doble de eso es:

2*(D + 1km) = 2*D + 2km

La distancia total recorrida sera la suma de las 3 semanas:

D + (D + 1km) + (2*D + 2km)

Simplificando los km, así solo queda una expresión algebraica, obtenemos:

D + (D + 1) + (2*D + 2)

Podemos simpliicar esto para obtener:

D + D + 1 + 2*D + 2

(D + D + 2*D) + (1 + 2)

4*D + 3

Entonces la representación algebraica simpliicada de los kilómetros recorridos durante el entrenamiento es:

4*D + 3

30, 32, and 34 Please! I WILL GIVE BRAINLIEST

Answers

Answer:

see explanation

Step-by-step explanation:

Since AL bisects ∠ KAT then ∠ 1 = ∠ 2

(30)

7x + 3 = 6x + 7 ( subtract 6x from both sides )

x + 3 = 7 ( subtract 3 from both sides )

x = 4

(32)

SAT is a straight line , then

∠ 1 + ∠ 2 + ∠ 3 = 180° , then

x + x + 4x = 180

6x = 180 ( divide both sides by 6 )

x = 30

(34)

Similar to (32)

x + 12 + x + 12 + 6x - 20 = 180 , that is

8x + 4 = 180 ( subtract 4 from both sides )

8x = 176 ( divide both sides by 8 )

x = 22

Answer:

30) x= 4

32) x=30

33) x=22

B. 452.16in^2
C. 37.68in^2
D. 354.95in^2

Please, show your work if you have a answer to this question.

Answers

Answer:

A: 113.04in^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2 where r is the radius

We know the diameter is 12 inches so the radius is 1/2 the diameter

r = 1/2 d =1/2(12) = 6inches

A = (3.14) (6)^2

A = 113.04 in ^2

Answer:

A. 113.04 in^2

Step-by-step explanation:

A = πr^2 where r is the radius of the circle

Radius = diameter/2

Radius = 12/2

Radius = 6

A = π(6)^2

A = π(36)

A = 113.04
