Answer:

216

Step-by-step explanation:

Use geometric formulas to solve for each individual SIDE of the triangular prism

TOP and BOTTOM TRIANGLE sides:

$\frac{ab}{2}$
$\frac{6(8)}{2}$ <--- times 2 because we have TWO identical triangle sides

RIGHT RECTANGULAR side from our perpsective:

LxW
8(7)

FRONT RECTANGULAR side:

LxW
7(6)

BACK RECTANGULAR side:

LxW
7(10)

Now you add all of those formulas together for your answer.

$\frac{6(8)}{2}$ + $\frac{6(8)}{2}$ + 8(7) + 7(10) + 7(6)

= 216

Helen plays basketball. For free throws, she makes the shot 78% of the time. Helen must now attempt two free throws. C = the eve

Answer:

0.6708 or 67.08%

Step-by-step explanation:

Helen can only make both free throws if she makes the first. The probability that she makes the first free throw is P(C) = 0.78, now given that she has already made the first one, the probability that she makes the second is P(D|C) = 0.86. Therefore, the probability of Helen making both free throws is:

$P(C+D) = P(C) *P(D|C) = 0.78*0.86\\P(C+D) = 0.6708$
