Answer:
7.5
Step-by-step explanation:
12/18 = 5/x
12x = 18(5)
12x = 90
/12 /12
x = 7.5

The speed of a yacht traveling a distance of 1.357 km in 165 minutes is 0.5 km/h
<h3>What is Speed?</h3>
The speed of an object is the distance covered by the object in respect to time.
Mathematically:
![\mathbf{Speed = \dfrac{distance}{time}}](https://tex.z-dn.net/?f=%5Cmathbf%7BSpeed%20%3D%20%5Cdfrac%7Bdistance%7D%7Btime%7D%7D)
![\mathbf{Speed = \dfrac{1.375 \ km}{165 minutes }}](https://tex.z-dn.net/?f=%5Cmathbf%7BSpeed%20%3D%20%5Cdfrac%7B1.375%20%5C%20km%7D%7B165%20minutes%20%7D%7D)
- We know that 60 minutes = 1 hour
- 165 minutes = 2.75 hours
![\mathbf{Speed = \dfrac{1.375 \ km}{2.75 \ hours}}](https://tex.z-dn.net/?f=%5Cmathbf%7BSpeed%20%3D%20%5Cdfrac%7B1.375%20%5C%20km%7D%7B2.75%20%5C%20hours%7D%7D)
Speed = 0.5 km/hour

Answer:
x=-8 then x times y coulum = x coulum answer same for if y=-9 then times x coulum =y coulum answers if y=x+5 solve for x be making y=0
Step-by-step explanation:
Start by piking the equations you want to use and put them on the lines below the box the take and put that into a table with that if it’s a x then you start with the y coulum and put -2,-1,0,1,2 ok then from their if you know what x is you times it by the y coulum and contiue to do that with all the x integers this is the same for the y integers except it’s switched. If you still don’t understand I suggest asking your teacher for help and be honest with them that you didn’t understand it.
Answer:
3/4
Step-by-step explanation:
Tangent is opposite/adjacent
Therefore, 6/8 would be the answer which simplifies to 3/4.
For cases like these, we need to find the base then multiply it by the height. Let’s separate the triangle and the rectangle of the base
Triangle:
1/2(6*9) = 27
Rectangle:
5 * 9 = 45
Total base:
45+ 27 = 72
Now for the area:
72 * 12 = 864 m^3
864 m^3 would be the volume.
