100+b^2=676
100-100+b^2=676-100
b^2=576
√b^2=√576
b=24

The Hickory Stick has a selection of 3 meats and 6 vegetables. How many different selections of one meat and one vegetable are p

valentina_108 [34]

The different selections of one meat and one vegetable are possible are 18 selections.

Since the Hickory Stick has a selection of 3 meats and 6 vegetables, the number of ways we can select one meat out of 3 is ³C₁ = 3.

Also, the number of ways we can select one vegetable out of 6 is ⁶C₁ = 6.

So, the total number of selections of one meat and one vegetable is ³C₁ × ⁶C₁ = 3 × 6

= 18 selections

So, the different selections of one meat and one vegetable are possible are 18 selections.

The triangle to solve for has a leg or 12 feet, hypotenuse of 20 feet, so solve for Pythagoras $a^{2} + b^{2} = c^{2}$ for a

$a = \sqrt{c^{2} -b^{2}}$

a = 16 feet
