Answer:
C
Step-by-step explanation:
standard form is ax + by = c, which is true for the third option.
2p - 3q - 4r + 6r - 2q + p = 0
2p + p - 3q - 2q - 4r + 6r = 0
3q - 5q + 2r = 0
Answer:
22 1/2 hours
Step-by-step explanation:
There are several ways you can get there. One way is to use table values to form a sum of 60:
cars = 32×2 - 8×(1/2) = 64 -4 = 60
Then the corresponding hours are ...
hours = 12×2 - 3×(1/2) = 24 -1.5 = 22.5
It will take 22.5 hours to wax 60 cars.
__
Another way to get there is to use proportions:
hours/cars = 3/8 = ??/60
Multiply by 60 to find ??
(60)(3/8) = ?? = 180/8 = 22.5 . . . . hours
_____
We can do these things because we have determined the relationship between hours and cars is proportional: 8/3 = 16/6 = 32/12. If it weren't proportional, some other strategy would be needed to answer the question.
<h3>Given:</h3>
- l= 5 meter
- b= 4 meter
- h= 3 meter
<h3>Note that:</h3>
- l= length
- b= breadth
- h= height
<h3>To find:</h3>
The volume of the given rectangular pyramid.
<h3>Solution:</h3>
First, multiply the length (5), breadth (4) and height (3).
Now, divide 60 by 3.
<u>Therefore,</u><u> </u><u>the</u><u> </u><u>volume</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>given</u><u> </u><u>rectangular</u><u> </u><u>pyramid</u><u> </u><u>is</u><u> </u><u>2</u><u>0</u><u> </u><u>cubic</u><u> </u><u>meters</u><u>.</u>
