Agrain of sand weights approximately 0.011 grams. there are approximately 7.5x10^18 grains of sand in the world. use scientific notation, calculate approximately how much all the grains of sand weight in the world.

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
