This look hard to do but it is not hard if you sort it out. Use vector addition.

North is 0 degrees. South is 180 degrees. N and S  will be the Y direction

East is 90. West is 270. E and W will be the X direction.

Use the cos function to give the Y values.

8*cos(0) + 2*cos(270) + 5*cos(120) = 5.5kph in the North direction

Use the sin function to give the X values.

8*sin(0) + 2*sin(270) + 5*sin(120) = 2.3kph in the East direction

Now take the arctan(5.5/2.3) =67.3 degrees. This is the true direction of travel.

Then take sqr(2.3^2 + 5.5^2) =6.0kph. This is the true speed to surface of Earth.

Rosala that is the funniest thing you ever write.

TR there is one writing by Edgar Allen Poe that remind me of you.  “Descent into the Maelstrom”   but you should really remember this one when you make a post "Quote the raven, Nevermore"

Maybe the rooster is bisexual. Hahaha

Maybe it should only depend if the “enemy” likes Rosala’s birthday or not.

Blast him!! Rosala

hahaha

Anon guest I think maybe you are picky about picket fences.

 Most paint cover 350 sq. ft. per gallon so that most likely what it is.

The fence is 26’ * 7’ = 182 sq.ft.

350/182 = 0.52 Gallon

Fences have two sides. I know because I painted a lot of them.

2 * 0.52 = 1.04 gallons

Hi Eloise

I know how to do this one.

Remember for a regular mirror the angle of incidents is equal to the angle of reflection.

Remember that 90 degrees is going directly into the mirror and 0 degrees is going across the surface and not reflect at all.

 The angle between an incident ray and the mirror is 30 degrees.  

subtract the 30 from the 90

90 – 30 = 60 degrees

The ray reflects at the same angle of 60 degrees

So the total angle is 120 degrees

My back is much better now. I go back to work next week. I have to take it easy for a while because it will take time to get back into shape. I visit the ranch some but I was not allowed to do any work because of insurance reasons. The dogs and horses and my mule were happy to see me and they really happy about the carrots and dog biscuits I brought.  They have their priorities. hahaha

Ninja I think you not have the right answer here.

The watch loose 12 minutes every hour so that is 20% loss. This mean the watch show 80% of real time. When the watch show 2:00 that is 5 hours past the 9:00 and that is 300 minutes. Divide the 300 minutes by 0.80 and that is 375 minutes. Divide the 375 minutes by 60 and that is 6.25. Adding 6.25 hours to 9:00 give 3:15.

The correct time is 3:15

Guest anon you are dumber than a box of rocks

Here’s another way

Call the long side X and the short side Y.

The parameter is

2X + 2Y = P

Also

Y=0.5X

So

2X + 2(0.5x) =10

3X = 10

X=3+1/3

Long side is 3+1/3  feet

Short side is 1+2/3 feet

Check

(2*(1+2/3))+2(3+1/3) =10 Feet

TR your answer look like a weapon of maths destruction

I hope you drive better than you do maths problems. Maybe you shouldn’t do both at the same time. I do maths while riding my mule, but he know where he is going better than I do. He help with the maths too.  hahaha

8 - 4[x - 3 - 7(x - 2)]

8 - 4[x - 3 - 7x + 14]

8 - 4x + 12 + 28x - 56

28x - 4x - 56 + 12 + 8

24x - 36
