Please help asap A plane traveling with the wind travels 900 miles in 5 hours. The return trip is against the wind and takes 9 hours. Find the rate of the plane in still air and the rate of the wind

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
