Answer:
1/7
Step-by-step explanation:
Since we do not know the number let us use the alphabet A to represent the unknown number
A × 1/3= 1/21
A/3= 1/21
Cross multiply both sides
A×21= 3×1
21A= 3
Divide both sides by the coefficient of A which is 21
21A/21=3/21
A=1/7
Hence the unknown number is 1/7
Answer:
a. 
Step-by-step explanation:
The given vector is v= 4i - 5j
The magnitude of this vector is;



The unit vector u in the direction of v is;



We rationalize to get

450/5= 90 units
90/5= 18 units
All you need to do is divide the real dimensions by the scale dimensions, and turn that answer to units. Notice: It said 1 unit: 5 feet
The scale drawing was 90 to 18 units.
I hope this helps!
