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.
Please let me know if this is correct or wrong.
Answer: 89/13 km
Step-by-step explanation:
3 4/13 + 2 5/13 + 1 2/13
= 43/13 + 31/13 + 15/13

48 i know because i used a calculator
Answer:
The measure of angle C is ![30\°](https://tex.z-dn.net/?f=30%5C%C2%B0)
The draw in the attached figure
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In the right triangle ABC
The sine of angle C is equal to divide the opposite side to angle C by the hypotenuse
![sin(C)=\frac{AB}{AC}](https://tex.z-dn.net/?f=sin%28C%29%3D%5Cfrac%7BAB%7D%7BAC%7D)
substitute the values
![sin(C)=\frac{4.5}{9}](https://tex.z-dn.net/?f=sin%28C%29%3D%5Cfrac%7B4.5%7D%7B9%7D)
![C=arcsin(\frac{4.5}{9})=30\°](https://tex.z-dn.net/?f=C%3Darcsin%28%5Cfrac%7B4.5%7D%7B9%7D%29%3D30%5C%C2%B0)
The width is 48 and the length is 144. I think
