Answer:
The correct answer is D. 3 % p. a .
Step-by-step explanation:
For the investment offered, Martin is supposed to get $180 as an interest ($6,180 - $6,000).
Now Martin is borrowing $6,000 from the bank to make this investment. He should be charged $180, so that he breaks even on investment.
Thus using the formula:
Interest= Principal × Time ( per annum) × 
; (Here simple and compound interest are same as the sum borrowed is to be charged for a single year)
⇒ 180 = 
× 1 × Interest rate
⇒ 180 = 60 × Interest rate
⇒ Interest rate = 3
Thus the correct answer is 3% per annum.
Answer:
126
Step-by-step explanation:
A Nonagon has 9 sides. To answer this, the polygon has to be regular.
The Perimeter is 9*14 = 126
Answer:
18. Scalene
19. Quadrilateral
20. option i)
Step-by-step explanation:
18. A triangle whose all the three sides are different is called a scalene Triangle . Where are whose two sides are equal is called an isosceles triangle and whose all the sides are equal is called an equilateral triangle. Here all the sides are of different measurement hence it is a scalene triangle.
19. A polygon containing
3 sides is a triangle
4 sides is Quadrilateral
5 Sides is a Pentagon
6 sides is a Hexagon
8 Sides is Octagon
Our polygon contains four sides, it is hence a quadrilateral
20.
Option i)
In two congruent figures , the corresponding sides and angles are equal.
corresponding side of s is side measuring 14 ft and that of t is the side measuring 12 ft
Hence s = 14 and t = 12
corresponding angles of u is angle measuring 90° and that of r is the angle measuring 90°
Hence ∠u = 90° and ∠r=90°
Answer:
Both graphs have a “y-intercept” at (0,0), so i believe the answer would be they don’t have y intercepts
