The Pyraminx is a Rubik's cube-type toy in the shape of a triangle-based pyramid. Every edge of the Pyraminx below is 15\,\text{cm}15cm15, start text, c, m, end text long. The pyramid's height is h=12.2\,\text{cm}h=12.2cmh, equals, 12, point, 2, start text, c, m, end text. The triangle drawn with dashed lines is a right triangle.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
