Answer: 8,100 cm^2
Step-by-step explanation: Area = S^2 so each side is sqrt(900) = 30cm
A square 3 times bigger has sides 30cm*3 = 90cm. The area for that square is 90^2 = 8,100 cm^2
Answer:
Y=6X+4
Step-by-step explanation:
Para este ejercicio solo disponemos de dos datos conocidos que son la pendiente que es 6 y un punto de la recta (0,4)
Para hallar la ecuación de la recta usaremos la conocida ecuacion punto pendiente:
Y-Yo=m(X-Xo)
Donde Xo y Yo son respectivamente las coordenadas del punto dado (0,4)
Xo=0
Yo=4
m=6----> m es la pendiente
Entonces remplazamos
Y-4=6(X-0)------>Remplazamos los valores dados
Y-4=6X-0-------->Destruimos los parentesisi aplicando distributiva
Y=6X+4 ----------->Finalmente despejamos el 4 que acompaña a la Y
Answer:
sinx = √2/3
Step-by-step explanation:
cos2x = 1-2sin²x
5/9 = 1-2sin²x
2sin²x =1-5/9
2sin²x = 4/9
sin²x = (4/9)/2
sin²x = (4/9)*(1/2)
sin²x = 2/9
sinx = √2/3
The cost of labour per hour is $90.56
The total amount paid by Austin is the sum of the total cost of labour and the cost of the parts
Total amount paid = total cost of labour + cost of parts
$553.50 = total cost of labour + $126
total cost of labour = $533.50 - $126
= $407.50
The total cost of labour = cost of labour per hour x total time worked
$407.50 = xx × 4.5
xx = $407.50 / 4.5
xx = $90.56
