Answer:
n = 15
Step-by-step explanation:
Since the triangles are similar the corresponding sides are in proportion, that is
=
( cross- multiply )
2n = 30 ( divide both sides by 2 )
n = 15
Answer:
I think its 150,not sure
Step-by-step explanation:
Answer:
The final amount would be about $365
Step-by-step explanation:
The formula for that would be A = P(1+i)^n
A = 300(1.05)^4
A = 300(1.21550625)
A = 364.651875
<u>Answer:</u>
The correct answer option is B. 72°.
<u>Step-by-step explanation:</u>
A polygon is said to be a regular polygon when all its sides and angles are equal.
So a regular pentagon coincides with its pre-image when it is rotated at an angle of 72°.
When rotated at an angle of 72°, a regular pentagon produces the same pentagon regardless of being rotated clockwise or anticlockwise.
Therefore, option B is the right choice.
Answer:
infinitely many
Step-by-step explanation:
You have the system
(1/2)x + 5y = 6
3x + 30y = 36
Multiplying the first equation by 6 results in 3x + 30y = 36, which is exactly the same as the second equation. The two graphs coincide, and so there are infinitely many solutions to this system
