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:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 4, 9) and (x₂, y₂ ) = (3, 5)
m = 
= 
= -
where is the original shape coordinates because we need the original coordinates to answer ir
The number 1 is neither prime nor composite. A prime number is a whole number with two divisors. Since the number 1 only has 1 divisor, itself, it is not prime. A composite number is a whole number with more than two divisors, thus it is not composite with only one divisor.
Answer:
-9,9
Step-by-step explanation:
To find the roots, we set this equal to zero
(x+9) (x-9) =0
Using the zero product property
x+9 =0 x-9=0
x =-9 x=9
