Answer:   56.58

Step-by-step explanation:

679 hotdogs sold / 12 hotdog buns in a package = 56.58

You would have had to open a total of 57 packages though

Answer:

7 7/12

Step-by-step explanation:

Find the amount of rolls in all that were donated:

60 x 12 = 720.

The total amount used is 679. Subtract 679 from 720:

720 - 629 = 91.

Find the amount per dozen. Divide 91 with 12:

91/12 = 7 7/12

7 7/12 is your answer.

Consider two boxes, one containing one black and one white marble, the other, two black and one white marble. A box is selected
valina [46]

Answer:

\frac{7}{12}

Step-by-step explanation:

Probability refers to chance of happening of some event.

Conditional probability is the probability of an event A, given that another event B has already occurred.

B_1,B_2 denote the two boxes.

In box B_1:

No. of black balls = 1

No. of white balls = 1

In box B_2:

No. of black balls = 2

No. of white balls = 1

Let B, W denote black and white marble.

So, probability that either of the boxes B_1,B_2 is chosen is \frac{1}{2}

Probability that a black ball is chosen from box B_1 = \frac{1}{2}

Probability that a black ball is chosen from box B_2=\frac{2}{3}

To find:probability that the marble is black

Solution:

Probability that the marble is black = \frac{1}{2}(\frac{1}{2} )+\frac{1}{2}(\frac{2}{3})=\frac{1}{4}+\frac{1}{3}=\frac{7}{12}

Solve and write multiplication equations 2/5g=3/5
Yanka [14]

Answer:

g=1.5

Step-by-step explanation:

you want to eliminates the 2/5 so you do that by dividing it by itself (since you do the opposite equation) you do this on both side (so do 2/5 divided by itself, and 3/5 divided by 2/5) getting you 1.5 therefore all you have on the left side if this equation is g so g=1.5
