Answer:
$0.07
Step-by-step explanation:
nails = 3.10/155 = 0.02/piece
screws = 7.65/85 = 0.09/piece
0.09 - 0.02 = 0.07
Take a single digit number with a decimal (Two digits total), times ten to the power of whatever. E is used for very large or very small numbers and helps shrink the writing down. Ex. 1E+20 is 1.0 with the decimal moved to the right twenty spaces.
AC is not the bisector of angle BAD. AC made both sides a triangle and every triangles angles have to add to 180 degrees. So 115+30= 145 meaning angle DAC is 35 degrees. So AC cuts through BAD but one side is 30 degrees and the other is 35(DCB and DAB are the same angle…they both have to add up to 65 degrees)
