Its just asking which angles are similar just list them in the same order on both sides
abc abc
cba cba
Answer:
A
Step-by-step explanation:
To find surface area of a cylinder, find the 2 circles which is the formula a=pi(r)^2, when you get that, multiply that by 2 because both sides count. Than the middle which I would imagine like a soda can. Cut a line right down the middle and hen you take it out, it looks like a Rectangle. Find the circumvented of the circle which would be pi(d)=circumfrence. Now after that you found the top side now the other side is 12 as shown here on the model and multiply thm together you’ll get 84 pi. Now those 2 circles would add up to 32 pi. Add them together youll get 116 pi. Now pi could be any but I’d Use 3.14 which will get you about to A becuase after all 3.14 is an approximate.
Total cost = 62 + (6% of 62) + (20% of 62)
- Find 6% of 62:
1% = 62 / 100 = 0.62
0.62 x 6 = 3.72
- Find 20% of 62:
10% = 6.2
6.2 x 2 = 12.4
Add everything together:
62 + 12.4 + 3.72 = 78.12
The total cost was $78.12
Answer:
x = -3
y = 7
Step-by-step explanation:
x + 3y = 18
-3x - 12y = -75
multiply first equation by 4
4 × (x + 3y) = 18 ➡ 4x + 12y = 72
now add the two equations up
4x + 12y - 3x -12y = 72 - 75 (-12y will eliminate 12y)
x = -3
