We are to solve the total area of the pyramid and this can be done through area addition. We first determine the area of the base using the Heron's formula.
A = √(s)(s - a)(s - b)(s - c)
where s is the semi-perimeter
s = (a + b + c) / 2
Substituting for the base,
s = (12 + 12 + 12)/ 2 = 18
A = (√(18)(18 - 12)(18 - 12)(18 - 12) = 62.35
Then, we note that the faces are just the same, so one of these will have an area of,
s = (10 + 10 + 12) / 2 = 16
A = √(16)(16 - 12)(16 - 10)(16 - 10) = 48
Multiplying this by 3 (because there are 3 faces with these dimensions, we get 144. Finally, adding the area of the base,
total area = 144 + 62.35 = 206.35
Answer:
0.66
Step-by-step explanation:
1.00 - 0.34 = 0.66
The probability of certainty is 100%=1
If Probability(p)=0.34
then
0.34+Probability=1
Probability(!p)=1−0.34=0.66
To square a number means to multiply it by itself. So 9 squared would be:
9x9
Which is
81
I hope this Helps!
The answer is (-4,-4) because y has to equal x, the first -4 is the x and the second one is the y
It's not time to try and simplify it until you HAVE an equation. You won't have an equation until you write down what. V*4x is equal to.
