A baseball player throws a baseball from a height of 1 m above the ground and its height is given by the equation h= -3.2^2+ 12.
8t +1, where H is the height in meters above the ground, and t, in seconds, is its time in the air [see the image below]. When, to the nearest tenth of a second, will the ball hit the ground? (You must solve by factoring)!!!<<<<< it's important that you do. please solve this ASAP
<span>Let us use the variable x for length. So width will be 1/2x + 3.
Perimeter = x+x+ 1/2x + 3 +1/2x + 3 = 3x + 6 = 66
Therefore 3x = 66-6 = 60
So x = 60/3 = 20
The length is 20 cm.
Therefore the width = 1/2 of 20 + 3 = 10 + 3 = 13 cm
Check: 20+20+13+13 = 66</span>
Step-by-step explanation: there are two white marbles and you want to know the probability of you not getting white so just subtract the white from the rest and put the rest of the marbles over ten
