Answer:
the correct answer is b (4,2)
Vectors and scalars are not the same quantity
4/3
you do y2-y1 divided by x2-x1
so 4-0 divided by 3-0 which gets you 4/3
Answer:
13
Step-by-step explanation:
243.50 - 130.50 = 104
104 ÷ 8 = 13
Assuming no border or waste, 9m by 16 m translates to 29.52' x 52.49'.
use 32/8=4 sheets of plywood to cover the width on the 8' side.
For the length, use 52/4=13 pieces on the 4' side.
This gives a total of 4*13=52 sheets.
The extra 0.49' x 29.52 can be covered using the extra from the last four sheets for the width.
Check:
Area to be covered: 29.52*52.49=1550 sq. ft.
Area of plywood supplied = 52*4'x8'= 1664 sq. ft, > 1550 sq.ft.
