Answer:
11.11 hours
Step-by-step explanation:
Rita = 20 hours
Neha = 25 hours
Let the time that they can complete the work together be written as x
1/20 + 1/25 = 1/x
Lowest Common Denominator is 500
25 + 20/500 = 1/x
45/500 = 1/x
Cross Multiply
45x = 500
x = 500/45
x = 11.111111111 hours
Approximately = 11.11 hours
Therefore, it would take Rita and Neha 11.11 hours to complete the work together.

Answer:
Required equation is
.
Step-by-step explanation:
Given,
Height of the tree=5x+6
Distance from feet of the tree=2x-4
To find straight distance from feet of Madeline to top of the tree.
Let the tree as y-axis and distance from base along x-axis. Then the distence of straight line from foot of Madeline to top is become the hypotenuse of the triangle. Thus if we let,
Distance from feet of Madeline to top of tree= p, then, according to law of finding third side of a triangle we get,


Hence the result.
Answer:
20737
Step-by-step explanation:
12^4=12*12*12*12= 20736
1^4= 1*1*1*1=1
