There are 12 different possibilities. Landing a heads and a six on top is 1 out of those 12 possibilities, there fore the answer is 1 in 12 or 8.33333333.
Answer:
5 seconds
Step-by-step explanation:
d = 16t^2
You are given the distance, d, and you need to find the time, t. Replace d with the given distance, 400 ft.
d = 400
400 = 16t^2
Switch sides.
16t^2 = 400
Divide both sides by 16.
t^2 = 25
Take the square root of both sides.
t = 5
Answer: 5 seconds
Answer:
12
Step-by-step explanation:
since you already know that the short sides together are 4 inches, that means there's 18 inches left, so 9 inches for each long side. Add 3 to 9 and you have your unknown number.
<span>A-2b=2
A-b=6
</span>
<span>A-2b=2
-2(A-b=6)
-2A+2b= -12
A-2b=2
-2A+2b = -12
-------------------
-A = -10
-A/-1 = -10/-1
A = 10
a-b=6
10 - b = 6
10-10-b = 6 -10
-b = -4
-b/-1 = 14/-1
b= 4
Check
a - 2b =2
10 - 2(4) =2
10 - 8 = 2
2=2
