Answer:
A
Step-by-step explanation:
The projection of vector B on unit vector a is
(B•a)a
av(unit vector of v)= 1/√2(-1,1)
u•av= 1/√2 × (-5+7)= √2
(u•av)av= √2 × 1/√2(-1,1)= (-1,1)
The maximum possible volume of this type of box that can be made from a 20 cm by 20 cm square of paper is 512cm³.
<h3>How to calculate the volume?</h3>
From the information, when the side of 1cm are cut, this will become an open box. The volume will be:
= 18 × 18 × 1
= 324cm³
Also, when 2cm is cut, the volume will be:
= 16 × 16 × 2
= 512cm³

Answer: 60 oranges
Step-by-step explanation:
<u>Given information</u>
Weight = 75 g / orange
Total = 4.5 kg
<u>Given formula</u>
Total = Number of oranges × Average weight
<u>Convert Kilogram unit to Gram</u>
1 kg = 1000 g
4.5 kg = 4.5 × 1000 = 4500 g
<u>Substitute values into the given formula</u>
Total = Number of oranges × Average weight
Number of oranges = Total / Average weight
Number of oranges = 4500 / 75
<u>Simplify by division</u>
