Answer:
4.097 s
Step-by-step explanation:
The formula for ballistic motion usually used is ...
h(t) = -4.9t² +v₀t +s₀
where v₀ and s₀ are the initial vertical velocity and height, respectively. Here, we have v₀ = (35 m/s)sin(35°) and s₀ = 0. We want to solve for h(t) = 0.
0 = -4.9t² +35sin(35°)t = t(-4.9t +35sin(35°))
This is true for t=0 and for ...
t = 35sin(35°)/4.9 ≈ 4.09697 . . . seconds
It will take about 4.097 seconds for the projectile to reach the ground.

Desmos has a setting option for angles in degrees. That is what we used here.
12 ÷ 3/4:
First, there are many ways to divide a whole number by a fraction. In my way, I take acknowledgment to the rules. There are other ways to do this, like the reciprocal way. To first get started, I'm going to give you the rule which is: (a ÷ b/c = a × c/b). We can now replace our numbers in the variables place.
Second, we can simplify. To do so, (12 × 4 = 48). 48 is our new numerator while we keep the denominator we started out with (3).
Third, this is where long division comes in handy. I can't exactly do it on a website, but I am going to try. It is best if done on a piece of paper.
