Answer:
It took 8 seconds for the leaf to reach the ground.
Step-by-step explanation:
The height of the leaf in feet can be found using the function:
y = -3.5*x + 28
where x is the time in seconds the leaf has been in the air.
You want to know how long it took for the blade to reach the ground. That is, the time it took for the blade to reach a height of 0 feet. So, replacing this value in the expression:
0= -3.5*x + 28
and solving you get:
-28= -3.5*x
(-28)÷ (-3.5)=x
8=x

___________________________________
;
= 95 ÷ 100 ;
Note: to divide a number by "100" ; you take the decimal place of the original number, and move the decimal space two spaces backward.
= 95. ÷ 100 = .95 ; → write as: " 0.95 " .

<u> Other method</u>:
19/20 = 19 ÷ 20 ; Use calculator; to get the exact number:
→ " 0.95 " ;
→ which is already rounded to the nearest hundredths place.
