Answer:
34 5/6
Step-by-step explanation:
Convert the mixed numbers into improper fractions:
57/10 × 55/9
We can reduce these fractions by using the greatest common factor, 3
19/2 × 11/3
Multiply
19/2 × 11/3 = 209/6
Convert to mixed number
209/6 = 34 5/6
184cm2
8x5=40x2=80
4x5=20x2=40
8x4=32x2=64
80+40+64=184cm2
Answer:
0.9 = 90%
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X between c and d is given by the following formula.

Miles per gallon of a vehicle is a random variable with a uniform distribution from 25 to 35.
This means that 
The probability that a random vehicle gets between 25 and 34 miles per gallon is:

So the answer is 0.9 = 90%
