Mai made costumes for the annual school play. She used 6 rolls of blue fabric. If each role has 392.4 in of fabric, what is the total length of the fabric she used? Write your answer in yards.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

anser is a

step-by-step explanation:

negitive slope

positive

step-by-step explanation:

the quadrant is facing upwards

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
