Answer:
-3
Step-by-step explanation:
Perpendicular slopes are always the opposite reciprocal of the original slope.
opposite= flip it
EX: 2→1/2, 1/4→4
reciprocal=change the sign
EX: 2→-2, 1/4→-1/4
So...
1/3→-3

Answer:
assuming no scrap loss, 32 pieces of standard 4x8 sheets
Step-by-step explanation:
1020/(8x4)=31.875
The answer is 78 because when you add all the numbers it equals 780 and you need to divide the end sum by the amount of numbers added to get it. So in the end there were 10 numbers added to equal 780 so 780\10 equals 78
If she only had 1 hour sessions she had 8 sessions in the first week because if you do 35 times 8 you get 280.
