Answer:
1280
Step-by-step explanation:
I think it is 1280 because 20*16*8/2=1280. I am not 100% sure.
Answer:
We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits. We then round the last digit. We fill in any remaining places to the right of the decimal point with zeros.
The square root of 49/196 is 1.01
1) First, solve one linear equation for y in terms of x .
2) Then substitute that expression for y in the other linear equation.
3)Solve this, and you have the x -coordinate of the intersection.
4)Then plug in x to either equation to find the corresponding y -coordinate.
