Answer:
The correct answer is 15 cm.
Step-by-step explanation:
Let the width of the required poster be a cm.
We need to have a 6 cm margin at the top and a 4 cm margin at the bottom. Thus total margin combining top and bottom is 10 cm.
Similarly total margin combining both the sides is (4+4=) 8 cm.
So the required printing area of the poster is given by {( a-10 ) × ( a - 8) } 
This area is equal to 125 as per as the given problem.
∴ (a - 10) × (a - 8) = 125
⇒ 
- 18 a +80 -125 =0
⇒ - 18 a -45 = 0
⇒ (a-15) (a-3) = 0
By law of trichotomy the possible values of a are 15 and 3.
But a=3 is absurd as a 
4.
Thus the required answer is 15 cm.
Answer:
105°, 75°, and 105°.
Step-by-step explanation:
If two straight paths intersect at a point , four angles will be formed.
These are pairs of vertical angles.
The adjacent angles add up to 180°
If one of the angles is 75°, the supplement will be
Therefore the three other angles will be , 105°, 75°, and 105°.
Answer:
Step-by-step explanation: fifty-four point zero three nine
Diameter is 9 inch so the radius is 9/2=4.5inch
Part A: 2πr=28.26inch
π=28.26/(2r)
π=28.26/(2*4.5)=3.14
Part B: πr^2=63.585inch
π=63.585inch/(4.5inch)^2
π=3.139753086
Part C: Both of the answers are correct but Part B is more percise because it has more significant figures.
