Answer:
96.56 kilometers
Step-by-step explanation:
The angles of a triangle add to 180 degrees so the remaining angle must be 90°.
This triangle is half a square. It's one of the two tired triangles of trig, the other being half an equilateral triangle, 30°/60°/90°.
Answer:
8624.03
Step-by-step explanation:
(8×1,000)+(6×100)+(2×10)+(4×1)+(3×1/100)
8000+600+20+4+.03
8624.03
Answer:
The standard, or near-average, atmospheric pressure at sea level on the Earth is 1013.25 millibars, or about 14.7 pounds per square inch.
The gauge pressure in my automobile tires is a little more than twice that value. If you live at a higher altitude, the pressure will be lower since there is less air above weighing down upon you. The pressure also varies by relatively small amounts as high and low pressure systems move past.
Step-by-step explanation:
Ok. first you have to pick x or y or whatever variable you have and the number multiplied with it has to be the same in each equation but one has to be positive and one negative.
lets pick x
y=-2x+6
3y=x-3/ *2
so the x are positive and negative we have to multiply the equation with 2
y=-2x+6
6y=2x-6
now you have to add the equations. you do that by adding each side of the equatins together like this:
y+6y=-2x+6+2x-6 the x will cancel out
7y=0
y=0
now just go back to one of the previous equations and put the y in it.
0=-2x+6
2x=6
x=3
here you go
