Answer:
hmmm i think you need to dod
Step-by-step explanation:
yeah
For example if we have 7/10 we have one 0 in the denominator so we move the decimal spot 1 to the left
So:
7.0 becomes 0.70 or .7
To make a decimal into a fraction:
0.32
Just add two zeros to the right and that means 2 0's will be added in the denominator
so:
0.32
32.0/100 or 32/100
Hope that helps :)
Answer:
30 s
Step-by-step explanation:
When the ball hits the ground h=0. To find the time t when this happens we must solve the equation h=0.
●h= 0
● -12t^2+360t =0
● t(-12t +360) = 0
● t = 0 or -12t +360 =0
● t=0 or -12t = -360
● t=0 or 12t =360
● t=0 or t=360/12
● t=0 or t= 30
The equation has two solutions.
The ball was fired with an initial speed of 800 feet per second so it cannot hit the ground at t=0.
So the ball hits the ground after 30 s.
One of the answers is equilateral because all of the sides are of equal length.
The other answer is acute because all of the angles are under 90º since they are all 60º. Hope this helps!
