We know that 455 students are in school today. This number represents only 70%.
We can write an equation to figure out how many students total go to
the school.
Equation:
0.70.5 = 455
What is the total numer of students?

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
