The millions place is before the second comma form left to right and fifty means tens place so skip to the left to times
Example:
←LEFT RIGHT→

Given:
The sides of the right triangular base measures 9 cm, 12 cm and 15 cm.
The height of the prism is 20 cm.
To find:
The surface area of a triangular prism.
Solution:
We know that, the area of a triangular prism is
Where, P is the perimeter of the triangular base and h is the height of the prism.
The sides of the right triangular base measures 9 cm, 12 cm and 15 cm. So, the perimeter of the right triangular base is
Now, the area of the triangular prism is
Therefore, the surface area of a triangular prism is 720 square centimetres.
Answer:
$72
Step-by-step explanation:
in a calculator type 20%x60 and it will say 12
so 12 is 20% of 60
then just add 60 and 12 together and it equals 72
here 8x and (2x+60) are corresponding angles
since line l1 and l2 are parallel, so the two angles will be equal
8x=2x+60
8x-2x=60
6x=60
dividing by 6
x=10
option D. 10 is correct
A(n) = 9 + (n - 1) * 8
2nd term....n = 2
A2 = 9 + (2 - 1)*8
A2 = 9 + 1 * 8
A2 = 9 + 8
A2 = 17 <==
4th term...n = 4
A4 = 9 + (4 - 1) * 8
A4 = 9 + 3 * 8
A4 = 9 + 24
A4 = 33 <==
11th term...n = 11
A11 = 9 + (11 - 1) * 8
A11 = 9 + 10 * 8
A11 = 9 + 80
A11 = 89 <==
