892.50 because you would take 850 multiply by.05 which equals 42.50 add 850 x 42.50 and you get the 892.50

a ribbion is 3 2/3 yards long. Mae needs to cut the ribbion into pieces that are 2/3 yard long.how much ribbion will be left aft

Lemur [1.5K]

To answer this question you need to divide to get the number of pieces and then multiply whats leff by 3 2/3.

Divide 3 2/3 by 2/3. There are a few ways to do this but I am going to turn 3 2/3 into an improper fraction and then divide.

So $3\frac{2}{3} = \frac{11}{3}$
Now divide
$\frac{\frac{11}{3}}{\frac{2}{3}}$
$\frac{11}{3} \times \frac{3}{2} = \frac{11}{2} = 5\frac{1}{2} = 5.5$

We can see she can get 5.5 pieces at 2/3. So .5 is going to be left over so we ask our self, what is .5 of 3 2/3? We times .5 by 3 2/3 = 1.83 yards left. If you want it into a fraction, it would be $1\frac{83}{100}$ yards left

Miranda found 4 pieces of an ancient ceramic bowl.

Fofino [41]

Answer:

There are many variables to determine if you have all the complete pieces some are the following:

1.- bowl size

2.- the way it broke

3.- the size of the pieces

4.- if the pieces can fit together

5.- if the bowl paint has the same figures

This is important to determine, since if they do not have these requirements, you can find different pieces of different bowls, which will make the pieces never coincide with each other.

A bag contains a number of marbles of which 35 are blue, 10 are red and the rest are

photoshop1234 [79]

Answer:

Y = 45*p(y) / (1 - p(y)) if I knew what p(y) is, we can find how many yellow marbles there are. p(y) = probability of choosing yellow.

Step-by-step explanation:

Total marbles = 35 + 10 + yellow

If probability of choosing yellow =p(y) = yellow/Total

p(y) = Y/(35 + 10 + Y)

Solve for Y,

p(y)*(35 + 10 + Y) = Y

45*p(y) + p(y)*Y = Y

45*p(y) = Y - p(y)*Y

Y = 45*p(y) / (1 - p(y))
