Answer:
x≈12.5
Step-by-step explanation:
angle a=90°,angle b=28°,side c=11
a+b+Y=180°
Using
y=62°
Using the law of sines, we calculate unknown side x
c=11, a/c=sin a°/sin y°
a=c*sin a°/sin y°
a=11*sin 90°/sin 62°=12.46
12.46≈12.5
Answer:
18 chaperones
Step-by-step explanation:
1. How many times does 25 go into 225
2. Whatever that number is multiply it by two
3. That is how you get the number of chaperones
4. THE END
Answer:
I'm guessing its b, but I'm not too sure
Step-by-step explanation:
You would get something like this. This is because with the first kid, they can get either Heads or Tails, two possibilities.
After this, the second kid can also cause either Heads or Tails but they are building on what the first kid had already done, so four possibilities.
Thsi keeps on multiplying on and on by 2 the more kids who flip a coin.
Answer: 27/36
Step-by-step explanation: It says there are 36 bikes (18 pairs), meaning that there are 2 bikes per pair because 18 multiplied by 2 is 36.
1 pair (2 bikes) are yellow.
3 pairs (6 bikes) are red.
For purple, add yellow and red together: 2 + 6 = 8. Subtract the total number of bikes from this: 36 - 8 = 28 purple bikes.
If you take out 1 purple bike, this leaves you with 27. The probability of choosing a purple bike out of the total (36), is 27/36.
