Scientific notation means a* 10 ^b
where a is number between 1 and less than 10
Move the decimal 9 places to the right which means the power of 10 is negative since we moved the decimal to the right
6.5
The power of 10 is -9
6.5 * 10 ^ -9
Answer:
C. A = 150
Step-by-step explanation:
A + 3x = 180
A = 9x + 60
9x+60+3x = 180
12x = 120
x = 10
A+3(10) = 180
A +30 = 180
A = 150
It would be 270 cm given that the top chape is 72cm and the bottom rect. is 198 cm.
