-72+36=54n
-36=54n
n=-36/54
Answer:
27 more
Step-by-step explanation:
7/11 x 99 = 63
4/11 x 99 = 36
63-36 = 27
Answer:
Below in bold.
Step-by-step explanation:
Work in times to fill 1 pail:-
tap A takes 55/4 seconds
tap B takes 50/3 seconds
Let time to fill one pail be x when filling together, then:
3/50 + 4/55 = 1/x
165x + 200x = 55*50
x = 2750 /(365) = 7.5342 seconds
To fill 16 pails it takes 7.5342* 16
= 120.55 seconds
= 2 minutes 1 second to the nearest second..
You will start with representing the area with the given information.
Then distribute the x
Next, subtract 170 from both sides.
A = lw
170 = x (x + 7)
170 = x^2 + 7x
0 = x^2 + 7x - 170 is the quadratic equation in standard form representing the area.
Subtract the minimum data value from the maximum data value to find the data range,so in this case yur data range is
10 - 0.08 = 9.92
so yur answer is 9.92
