R = Red's rate
R-6 = Wolf rate
432/R = 432/(R-6) -1
432(R-6) = 432 R - R(R-6)
Solve for R = 54 m/hr (via Quadratic Formula after simplifying) Wolf = 48 m/hr
12. a 5 laps * .526 mile/lap * 1.61 km / mile * 1000 m / km = ......... m
can you now try the rest of the Q's?
These questions are basically conversion of units
211 years * 365.25 days/year * 24 hours/day * 3600 sec/ hour = .......... secs
Right triangle has TWO angles 65o remaining angle (lower left)is 50o
180 - 50 = 130 = angle on right side of right triangle
remaining angles in right triangle are equal 180 - 130 = 50 equal angles means each are 25o
1/6 + 1/x = 1/4
x = 12 hrs
Subtracting 3 from x x-3 shifts the graph to the right 3 units , so the x-intercepts will now be -1 and 5
Just use the website calculator to divide 11 by 81 :
11/81 = 0.135802469135802469......
The second equation (y=3x-11) defines y substitute this for 'y' into the first equation
5x + (3x-11) = 13 now solve for x then use this value of x in one of the equations to solve for 'y'
y = 6x^2 + 18x + 14 divide by 6
= 6 (x^2 + 3x) + 14 complete the square
= 6 ( x + 1.5)2 - 13.5 + 14
= 6 (x+ 1.5)2 + .5
Use Pythagorean theorem to find the diagonal (hypotenuse) of the screen
d2 = 252 + 182 solve for d ( note: this equation finds d2 )
