Suppose the time taken for the repairman to fix one pair of shoes is x, time taken by the assistant will be 1.5x.
The number of shoes repaired by shoe man in an hour will be:
1/x
the number of shoes prepared by assistant in 1 hour will be:
1/1.5x
the number of shoes repaired by both of them in 1 hour will be:
8/20
hence;
1/1.5x+1/x=8/20
2.5/(1.5x)=2/5
cross-multiplying our equation we get:
2.5*5=1.5x*2
7.5=3x
x=7.5/3
x=2.5 hours
therefore we conclude that it takes the repairman 2.5 hours to fix one pair of shoes.
Answer: 8.2×10-3^1, I think the second part of the answer is 4.4×10^1 (44)
I think this is right but I'm not a mathematician.
Step-by-step explanation:
The first problem is 7.9×10^1 (79)
Second problem 4.6×10^1 (46)
Third problem 3.5×10^1 (35)
Answer:
Step-by-step explanation:
y(x) = (1/8)^x
y(1/3) = (1/8)^(1/3) = 0.5
Answer: OPTION C.
Step-by-step explanation:
Given the following formula:
You know that "S" is the smelliness of cheese, "B" is the number of bacteria in the cheese and "A" is the surface area in square centimeters of the cheese.
For example, suppose that there are 
in a surface area of 
.
Substitute into the formula these values:
And then evaluate:
Therefore, you can conclude that the appropriate measurement unit for "S" is:
0,0
