22.9 is the closest but not exact. It was probably rounded off.
I used the formula: leg^2+leg^2=hypotenuse^2
(You can use that formula for any right triangle.)
Answer:
$1.44
Step-by-step explanation:
<u>Store A:</u>
12 bottles of water for $3.36
Then
48 bottles of water for 
(48 bottles is 4 times greater than 12 bottles)
<u>Store B:</u>
24 bottles of water for $6.00
Then
48 bottles of water for 
(48 bottles is twice greater than 24 bottles)
<u>Difference:</u>
When it hits the ground the height would be 0.
Set h to 0 and solve for t ( time)
0 = -16t^2 + 112t + 144 divide both sides by -16:
T^2 -7t -9
Factor the polynomial :
( t- 8.1) (t+1.1
Solve for t setting each equation to 0:
T = 8.1 or t = -1.1
Time has to be positive, so the answer is
8.1 seconds
Depending on how everything gets rounded it could also be 8 seconds.
-vp+40<95
subtract 40 from each side
-vp < 55
divide by -p (which flips the inequality) assuming p>0
v > -55/p
When you roll a dice you will have side with 1-6 each has equal chances.
so the possible outcomes are 1,2,3,4,5,6
