Hi!
The formula for a triangular prism's volume is
(V = volume, b = base, h = height, w = width)
V = 0.5 · b · h · w
^ the answer
Hope this helps! :)
The total should be 287.59. You add the numbers (127.12+94.50+65.97) and it should equal to that.
0.91428571428 is 5 and 5/7- 4 and 4/5
Answer:
$132
Step-by-step explanation:
1) In this system of eqn x represents the price of washing cars and y represents the price of washing SUVs
2) From the given eqn,
y = (84 - 4x)/2
and
y = (126 - 3x)/5
equating both the equation,
(84 - 4x)/2 = (126 - 3x)/5
=> 210 - 10x = 126 - 3x
=> 7x = 84
=> x = 12
=> y = (84 - 48)/2 = 18
Hence the co-ordinate of intersection will be (12,18)
3) The total cost of 1 car and 1 suv = x + y = 12 + 18 = $ 30
4) The total earning of hour 3
= 5x + 4y
= 5.12 + 4.18
= 60 + 72
= $ 132
