Hello,
The key to doing these problems is writing the fraction for each event and multiplying them.
I will do the first problem for you.
First, you have to draw an ace. The chances of that are 4/52.
Then, you have to draw a jack. The chances of that are 4/51.
We changed 52 to 51, because we didn't replace the ace that we drew the first time.
Multiplying those fractions gives us the answer 4/663.
I hope this gets you started in the right directions,

This is an obtuse triangle because one angle of it is greater than 90 degrees :)
Answer:
Step-by-step explanation:
Three equal sides, so lets find one by solving for x
6x + 16 = 9x-11
-3x = -27
x = 9
6(9) + 16 = 70
9(9) - 11 = 70
70(3) = 210 cm
The first one is 6 1/6 feet
The answer is, C
2x +3y=7.20
4x+2y=8.80
