Answer:
10 hours
Step-by-step explanation:
(150/x) + 1.5 + (450/(x+15)) = 600/x
Multiply through by x(x + 15):
150(x + 15) + 1.5x(x + 15) + 450x = 600(x + 15)
150x + 2250 + 1.5x^2 + 22.5x + 450x = 600x + 9000
150x + 2250 + 1.5x^2 + 22.5x + 450x - 600x - 9000 = 0
1.5x^2 + 22.5x - 6750 = 0
x = (-22.5 +/- sqrt(22.5^2 - 4(1.5)(-6750))) / (2*1.5)
x = (-22.5 +/- sqrt(506.25 + 40500)) / 3
x = (-22.5 +/- sqrt(41006.25)) / 3
x = (-22.5 +/- 202.5) / 3
x = 180/3 or -225/3
x = 60 or -75
But a negative number doesn't make sense, so therefore x = 60, so the journey took 600/60 = 10 hours.
Dont know a but b is
75=100-2p
75 minus 100 = -25=-2p
-25/-2= p
p=$12.50
Answer:
The area of a parallelogram is its base times its height.
Step-by-step explanation:
Area is for 2 dimensional shapes. (Shapes with two dimensions in parallelograms they are often referred to as base times height, or length times width). Area is the space inside a two dimensional object, and to find this use the length and the height to find the space in the 2-D figure.
Side note: Volume is "the area of 3 dimensional figures". Three dimensions meaning Length, Width and Height. So there is no area for 3-D figures. (unless you are using Surface Area)
Hope this Helps!
