Aheart beat takes 0.8. how many seconds os it written as a fraction

The problem is asking you to convert 0.8 into fraction form. The number 0.8 is in decimal form and to change it to fraction form you have to get the number after the decimal point which is 8 in this problem.

8 would be the numerator of the fraction. Next step is to count how many numbers are there after the decimal point. In this problem, there is only one number so there will only be one zero beside 1 (10). 10 will be the numerator.

So, the fraction would be 8/10 or 4/5 (simplified form)

idk man good luck man

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
