Answer: The correct equation is the option A.)A = x(x − 4) − 0.5(8)(x − 4) − 4(8)
Step-by-step explanation:
To find the painted area of the theater room in square feet, the following steps must be followed:
1. Determine the area of the theater room
Length: x
Width: x-4
A (theater room) = x (x-4)
2. Determine the area of the right triangle
Height: x-4
Base: 8
A (right triangle) = 0.5 (8) (x-4)
3. Determine the area of the rectangle inside labeled closet
Length: 8
Width: 4
A (closet) = 8 (4)
4. The area to be painted will be the substraction between the total area of the theater room, less the area of the right triangle and less the area of the rectangle of the closet like this:
A= A(theater room) - A(right triangle) - A (closet)
A = x (x-4) -0.5 (8) (x - 4) - 4 (8)
Therefore, the correct equation to solve by area is option A
So 1 yard=3 feet
1 feet=12 inches
1 yard=3 times 12 inches=36 inches
she has 3 pieces of ribbon each is 25 yards long
total inches=3 times 25 times 36=2700
how many 22's are in 2700
divide
2700/22 and round down
122.7
you can't have 0.7 of a 22 inch piece so round down to 122
the nasewr is 122 pieces
Answer:
22.25 ft long
if you add 10.5 with 11.75 you'll get 22.25
Answer:
El precio de la entrada al cine es de <em>$56</em>
Step-by-step explanation:
Cada uno de los 4 amigos las 2 veces por semana consumen un paquete de palomitas que cuesta: $28 ; entonces debemos multiplicar el costo de las palomitas por las dos veces que las consumen para saber el costo total de las palomitas:
28 x 2 =$56
El ejercicio nos dice que al no comer esas dos veces palomitas pueden ingresar a cine una tercera vez por semana ,lo que significa que al no pagar los $56 en palomitas podrán pagar una tercera entrada,lo que quiere decir que la entrada a cine es de $56.
Entonces podemos hacer la siguiente relación matemática: <em> Precio total de las palomitas dos veces por semana = Precio de la entrada a cine</em>.
