Answer:
It will take a total of 2.73 hours if they worked together
Step-by-step explanation:
Here, we are seeking to calculate the joint rate.
Let the amount of work to be done is say x
Seth’s rate will be x/6 , while violet’s rate will be x/5
Their joint rate will be ;
x/6 + x/5 = 11x/30
The time it will take them to build the house together will be equal to the amount of work divided by the joint rate.
That will be x divided by 11x/30
= x * 30/11x
= 30/11 hours which is Approximately 2.73 hours
Answer:
Step-by-step explanation:
Basically, if you want to find the probability of getting either outcomes, you will need to subtract the probability of getting neither outcomes in the question. The probability for both outcomes are 7/9 and 5/9 respectively. You will have to multiply to get the probability of getting both of the non-desired outcomes. Hence, it gives the equation above
the answer to the problem y=−15x3+18x2
Answer:
I cant tell is the 'x' is supposed to be a variable or a multiplication sign. IF its a multiplication sign then the answer is -30. Btu if its a variable then its in its simplest form there isn't any way to solve that equation.
13x = 39 can replace 3x + 5y = 59 in the original system and still produce the same solution.
