You are sitting in a car going 20 m/s relative to the ground and decide to throw a ball backwards with a velocity of 4m/s relative to your car. A person in another car behind you sees the ball moving towards him with a velocity of 2.50 m/s relative to his...

How to Arrange multiplication and division symbol as you wish between number 1 to 9 to get a result of 1.

oooo I see thank you so much, I just figured that the ratio of the car1 to the ball would equal the ratio of the car2 to the ball for some reason but this makes so much sense ! much appreciated!!!

Given : x^2+y^2=26 x+y=6 squaring on both sides (x+y)^2=6^2 x^2+y^2+2xy=36 ==>26+2xy=36 ==>2xy=10 ==>xy=5 ==>x=5/y now (5/y)^2+y^2=26 ==>y^4-26y^2+25=0 on futher solving x=1 or 5 y= 5 or 1

if you add both the equations you will get an equation 2(x^2-11x=-24) solving this equation x=8 or 3 on solving this equation with values of x we get y=0

next three terms are 100,121,144 here the formula is 6^2,(6+1)^2,(6+2)^2,.............

In a quadrilateral sum of angels is equal to 360degrees given 2 of its angels are at 90 degrees and 100 degrees and two angels are equal. let the other angel be X degrees =>100+90+X+X= 360 => 190+2X=360 => 2X=360-190 => X= 170/2 => X=85
